@@tulugusivakumar3510 ji your led driver (power supply ) may be faulty, mostly filter capacitor in case of smps type. or pf capacitor in case of pf driver type.
Pahle connectivity confirm karen, ki LEDs kaise or kitne lage hain oonki grouping kaise hai. Fir driver ka output voltage ke according per group voltage drop estimate karen. Each group ko diode ke seriey combination se bypass karen. Ek diode 0.7V ka drop dega. LED Circuit sahi tarike se complete ho jayegi to tube glow kar jaayegi.
If blinking is fast with sufficient brightness then probably the electrolytic capacitor (input side and/or output side) in driver circuit is faulty. Change the capacitor or replace the complete driver. Thanks for asking.
Check the voltage across the faulty LED and then connect the number of diodes by dividing that voltage by 0.7 (approx) . If your case is of a tubelight then probably other LEDs of that particular group will be blown off in a few days. Then apply 4-5 diodes for that particular group of LEDs.
It is a difficult situation, yet we can try following.Try to find any 20 watt faulty tube, use driver circuit of that. In second method we can try this take one diode 1 N 5408, one 40 watt or 60 watt incandescent bulb in series. Connect this series combination to the led strip. Connect the diode with appropriate polarity. I think tube should glow but I am not sure. Flickering may also be observed. If a bridge is used in place of single diode then flickering will be less.
You can cancel with a single wire and the electronic supply auto adjust down the voltage for the remaining LEDs in the row. Because it senses mili amps and when it reaches the amp the switching supply cut the current, so the less LEDs in the row the faster the supply switches... And the voltage is correct for the remaining number of LEDs.
Not necessarily SMPS will lower the voltage. In fect adding few more diodes will add life of remaining LEDs. If set of 5 to 7 LED can be soldered than it will work well .
1 watt ke liye 68 to 82 ohm 2 watts ke liye 47 ohm to 68 ohm. Hamesha pahle jyada ohm ko try karen. Agar sahi na lage to kum ohm se try karen. Resistor mota wala 2 watt wala use Karen.
Generally driver power supplies of LED tubes are slightly auto adjustable, so if diodes are not used then also the remaining diodes will glow but some generic drivers may not auto correct the voltage and remaining LEDs may got fused.
Agar driver ka DC output na aa rha ho to driver repair krne ki koshish karen. Driver mein adhiktar input and output electrolytic capacitor ka issue rahta hai.

Actually wo capacitors nahi balki diodes hain. Short karke v chal jata, but kuchh local company ke tubes mein driver supply auto adjust nahi hota hai. Fuse LED ko Short krne pe tube ke liye lower supply voltage ki requirement rahegi. Isliye agar short krne ke baad agar driver supply auto adjust nahi hui to baki led ko jayada supply milne lagegi aur unki life kum ho jayegi. Ek diode 0.7V ka drop deta hai to 5 diode 3.5V ka drop dega. Is tarah poori strip safe rahegi.
Shukriya Janab, 5 diode lagaye hai. Kyonki jo char LED kharaab hue the oonke badle Series mein voltage drop dene ke liye. Nahi to baaki LED pe jyada voltage chale jaayenge aur tube fir se jaldi kharab ho jayegi.
@@AnArjArt maximum 8-10 LEDs can be bypassed by direct soldering. It's driver supply voltage is auto adjustable up to some extant, so in case of bypassing also rest of LEDs will not burn. But dont bypass too many LEDs. Moreover, each faulty LEDs need not to short as some LEDs are grouped in parallel, so just short any oneLED of each group.

what if damaged LEDs are more in number than the good ones....? In that case we have to solder SMD LEDs to maintain the brightness of the tube-light rather than putting the PN Junction Diode..... Is not it??
Yes replacing the LEDs with new spare LEDs is the best way to repair the tube. But if the fault occurs frequently then it is better to replace the complete tubelight with a new one. Coz all equipments have limited operational life.

@@ShishuTechno Would it be possible to put one white LED in series and get the same 3.5 V drop and also get some light? Is your solution using ordinary diodes because you didn't have any white LEDs with you and used some equivalent readily available diodes as a fix? Is my understanding correct?
@@meta5291 Your idea is little closer to mine. I did not have spare LEDs available, so took five diodes to get 3.5 V drop. Whenever LEDs are fused in a LED tube, they always fuse in parallel. In my case, 4 parallel LEDs sharing current are fused together. Single LED will not be able to bear full current, it will fuse immediately. The four parallel leads will have to be replaced simultaneously. Thanks for sharing ideas.
@@ShishuTechno Thank you for the quick response. Also, I think you mean diodes in series, not parallel. I want to ask you about dimming these led lights (I saw the bigclivedotcom videos, but I think the circuits and IC used by the bulbs sold in UK are different.
@@meta5291 If you want to control the light intensity of the tube, you will need to install a variable buck converter, that too on the secondary side of the driver supply not on the primary side. For example, the driver output in my tube is 80 - 90 volts, so my tube can be controlled by using a 130 volt variable buck converter, considering 50% safety margin. Though it is a bit difficult to find such a high voltage buck converter. Such type of DIY implementation will be costlier and helter-skelter than readymade available products.

Sir mere led sab thik hai par main 2 points pe supply dene ke baad led glows nahi ho rahi hai
@@esmSKgaming6059iska driver output voltage kitna mil raha hai.
Dada 10-20 led kharab ho jay to kya kare
Pahle connectivity confirm karen, ki LEDs kaise or kitne lage hain oonki grouping kaise hai. Fir driver ka output voltage ke according per group voltage drop estimate karen. Each group ko diode ke seriey combination se bypass karen. Ek diode 0.7V ka drop dega. LED Circuit sahi tarike se complete ho jayegi to tube glow kar jaayegi.
Are bhai naya led le lo
Sir agar 1 led kharab hai to bhi 5 diode lagana parega kya ?????
@@mr.lucchaboys baki LEDs glow kar rahi hai hai? Ya off hain?
Can same process working for 18 watt ac led bulb.
Yes it will work for an LED bulb too.
If light is blinking ,new driver is required ?
If blinking is fast with sufficient brightness then probably the electrolytic capacitor (input side and/or output side) in driver circuit is faulty. Change the capacitor or replace the complete driver. Thanks for asking.
Sir in very few cases led is damage in maximum cases it is in rf or others location
Kitne volt ki hoti ye led light
3-3.2 V agar 2835 SMD LED use hua hai to
If 1 led is not working then how many diode to be used.
Check the voltage across the faulty LED and then connect the number of diodes by dividing that voltage by 0.7 (approx) . If your case is of a tubelight then probably other LEDs of that particular group will be blown off in a few days. Then apply 4-5 diodes for that particular group of LEDs.

#ShishuTechno If circuit is damage then which kind of circuit to be fix. Because there in market same circuit is not available. Pls suggest
It is a difficult situation, yet we can try following.Try to find any 20 watt faulty tube, use driver circuit of that.
In second method we can try this take one diode 1 N 5408, one 40 watt or 60 watt incandescent bulb in series. Connect this series combination to the led strip. Connect the diode with appropriate polarity. I think tube should glow but I am not sure. Flickering may also be observed. If a bridge is used in place of single diode then flickering will be less.
@@ShishuTechno Already try this method. 3/4 days is glowing ok but after 3/4 days 20/30w driver also damaged. Now what to do?
Very useful information sir 👍
Thanks for your compliments🙏
You can cancel with a single wire and the electronic supply auto adjust down the voltage for the remaining LEDs in the row. Because it senses mili amps and when it reaches the amp the switching supply cut the current, so the less LEDs in the row the faster the supply switches... And the voltage is correct for the remaining number of LEDs.
r u sure?
Not necessarily SMPS will lower the voltage. In fect adding few more diodes will add life of remaining LEDs.
If set of 5 to 7 LED can be soldered than it will work well .

Koi LED weak hai, led short method se check kijiye.
Driver supply ki voltage v check kijiye, low to nahi ho rahi hai
great and learned something today. i too have four tubes with me i will try out
अलग-अलग वाट के एसएमडी प्लेट में एसएमडी खराब हो जाने पर कितने वाट के एसएमडी के जगा पर कितने कितने नंबर का रजिस्टेंस यूज करें
1 watt ke liye 68 to 82 ohm
2 watts ke liye 47 ohm to 68 ohm.
Hamesha pahle jyada ohm ko try karen. Agar sahi na lage to kum ohm se try karen. Resistor mota wala 2 watt wala use Karen.
Very nice explanation thanks 👍 I'm a new subscriber ❤
Welcome my friend, Thank you very much🥰
What will happen if diodes are not used?
Generally driver power supplies of LED tubes are slightly auto adjustable, so if diodes are not used then also the remaining diodes will glow but some generic drivers may not auto correct the voltage and remaining LEDs may got fused.
@@ShishuTechno thank u
Agr dc he na ahy to phr kya krna pary ga
Agar driver ka DC output na aa rha ho to driver repair krne ki koshish karen. Driver mein adhiktar input and output electrolytic capacitor ka issue rahta hai.

@@ShishuTechno Sir Solution kya hai baaki bulb jalane ka.
@@राधेकृष्णा1 saamne dekhne se jyada pata chalega, waise mujhe lagta hai aapne jo LED nikalne ke liye jo desolder karne ka try kiya hai uske kaaran track short ho gayi hai, multimeter se short kijiye. Agar short mile to soldering iron se short clean kar dijiye ooske baad LED bypass kijiye.
My led tube same type - when starts it is lighting blow no problem. But after about 5 minutes start flicking. On off on off. It is disturbing. Having purchased for Rs.250.00 what is the use? If I bought same Rs.250.00 normal tube light Patti and tube set I would be able to change the tube as and when necessary. Please give solution for this on and off. Electric shop doesn't do this repair. Where can I get "diode"? It's price?
Flickering means probably some LEDs might be faulty. First identify the faulty LEDs then bypass it with diodes. Diodes are easily available at electronic spare shops. Price is maximum 1/- per piece. Sometimes driver capacitor may also be faulty.
Tub light 4 jagah led bandh hai to kaya kare
Jyada LED kharaab hai to poori tube hi change karna thik rahega.

Sir light tho On hora hai magar on honeke 10 second ke baad automatic off hora hai ,, so kya problem ho sakta hai ?
@@RealmeTv-i9v jyada possibility hai driver ke circuit mein koi electrolyte capacitor kharab hoga. Kabhi kabhi koi led weak hone pe v ye problem hota hai.
Aapne iske andee capacitor lagaya iske alawa aap us led ko direct bhi kar sakte the na, matlab jo led kharab hai usko nikal kar uske - aur + dono ko soldering se mila dete ho jata, to fir capacitor lagane se kya hota hai, aur capacitor 1 kyu nahi lagaya 4,5 kyu lagaye ek baar ye explain karke bataiye na ...
Actually wo capacitors nahi balki diodes hain. Short karke v chal jata, but kuchh local company ke tubes mein driver supply auto adjust nahi hota hai. Fuse LED ko Short krne pe tube ke liye lower supply voltage ki requirement rahegi. Isliye agar short krne ke baad agar driver supply auto adjust nahi hui to baki led ko jayada supply milne lagegi aur unki life kum ho jayegi. Ek diode 0.7V ka drop deta hai to 5 diode 3.5V ka drop dega. Is tarah poori strip safe rahegi.
Very informative video. 5 diode kue lagaiy hey? Shukeria.
Shukriya Janab, 5 diode lagaye hai. Kyonki jo char LED kharaab hue the oonke badle Series mein voltage drop dene ke liye. Nahi to baaki LED pe jyada voltage chale jaayenge aur tube fir se jaldi kharab ho jayegi.

@@ShishuTechno okay thanks for reply
Hi sir...what we do,when 8 or more led is gone in different places...
Hi sir, in case of too many faulty LEDs, it is not advisable to repair the strip, instead replace the complete tube. Thanks for asking.
@@ShishuTechno what will happen, solder or shorting each side of defective leds!
@@AnArjArt maximum 8-10 LEDs can be bypassed by direct soldering. It's driver supply voltage is auto adjustable up to some extant, so in case of bypassing also rest of LEDs will not burn. But dont bypass too many LEDs. Moreover, each faulty LEDs need not to short as some LEDs are grouped in parallel, so just short any oneLED of each group.
Для питания светодиодов наверное применен драйвер то есть стабилизатор тока ?
хорошо, вот почему ток остается постоянным, но напряжение постоянно немного меняется.
@@ShishuTechno есть понятие падение напряжения на светодиоде и напряжение меняется в зависимости от количества светодиодов а драйвер стабилизирует ток, считаю что цепочка из кремневых диодов бессмысленна в данном случае
@@logosrema7105 Да, вы правы, в современных лентах используется концепция падения напряжения на светодиоде с отслеживанием постоянного тока. Но я видел, что в некоторых нестандартных лампах используется только фиксированный регулятор напряжения. Как и в этом драйвере полосы, я проанализировал, что точное отслеживание постоянного тока не работает, поэтому он плавит меньшие полосы. Возможно, виноват водитель. В любом случае, я получил ценную информацию от вас. Спасибо, мой друг, что обновил меня.

Tube light blinking... What problm.... Pl reply
Either some LED fuse or driver capacitor faulty. First check LEDs by shorting method as shown in in this video.
बहुत अच्छी जानकारी दी
Sir ...यह tubelight कितने watt की है...
20 Watt ki hai sir ji syska ki.
great ! but better to replace the open leds with originals ones ...
Yes agree👍
LED check karte samay Sare led blink karta hay ab kaya karma caheay
Agar short karne pe saare LED blink karta hai to ho sakta hai ki driver supply kharaab ho , ya koi aur led kharaab ho. Jyada chance hai ki driver ka capacitor kharaab hoga.
@@ShishuTechno thank you sir
Very nice Jankari Kay liya Thanku @
Thank you very much
Jankari ke liye thank u🎉
what if damaged LEDs are more in number than the good ones....? In that case we have to solder SMD LEDs to maintain the brightness of the tube-light rather than putting the PN Junction Diode..... Is not it??
Yes replacing the LEDs with new spare LEDs is the best way to repair the tube. But if the fault occurs frequently then it is better to replace the complete tubelight with a new one. Coz all equipments have limited operational life.
@@ShishuTechno : Thanks for clarifying... Great

Ok noted
After connection life of tube?
I have repaired 4 such types of tubes, all are working ok, one oldest is working fine for last 4 months inside my house 🏠. Now it's a proven method.
@@ShishuTechno Would it be possible to put one white LED in series and get the same 3.5 V drop and also get some light? Is your solution using ordinary diodes because you didn't have any white LEDs with you and used some equivalent readily available diodes as a fix? Is my understanding correct?
@@meta5291 Your idea is little closer to mine. I did not have spare LEDs available, so took five diodes to get 3.5 V drop. Whenever LEDs are fused in a LED tube, they always fuse in parallel. In my case, 4 parallel LEDs sharing current are fused together. Single LED will not be able to bear full current, it will fuse immediately. The four parallel leads will have to be replaced simultaneously. Thanks for sharing ideas.
@@ShishuTechno Thank you for the quick response. Also, I think you mean diodes in series, not parallel. I want to ask you about dimming these led lights (I saw the bigclivedotcom videos, but I think the circuits and IC used by the bulbs sold in UK are different.
@@meta5291 If you want to control the light intensity of the tube, you will need to install a variable buck converter, that too on the secondary side of the driver supply not on the primary side. For example, the driver output in my tube is 80 - 90 volts, so my tube can be controlled by using a 130 volt variable buck converter, considering 50% safety margin. Though it is a bit difficult to find such a high voltage buck converter. Such type of DIY implementation will be costlier and helter-skelter than readymade available products.
