@@mostafa221 check for shorted SMD ceramic capacitor on the half where you read 0V of when this half( of source driver panel) is connected to t con. Also run cold diode test to see if this voltage line is not shorted to ground. If you dont find any shorts on resistance test the next test is to check COF driver on the affected side. You can cut Vgh/Vgl lines neer the corner of the screen or cut the entire COF off completely. Mąkę sure you cut the right COF on correct side though:)
Hello, good afternoon. Question what if the short is on the other side or right side of the panel so how can I block the clock signal on the other side?
If both sides are Short then its not Repairable, in most cases the complaints is in right side that as shown in video we can block vgh, vgl tracks using tapes by blocking connection in ffc cable as shown in video, if the complaint is in left side blocking is not possible we need cut the vgh, vgl tracks going to the panel in left side
@@ElectroPixels damn its the information that i search for , im on a samsung un65mu6900 with the first shorted COF in my case it affect the panel in all manner its for 99% of my sources , NOT repairable im about to try to isolate shorted lines betwerrn the cof and the pannel , i will mesure some thing before , like theses new lines ive just discover thanks man from quebec canada ( theses set have no side driver , i suspect this cof contain side drivers
It's just a temporary solution, Permanent Solution is Panel Replacement and its more costly so use the PANEL maximum using this type of methods then replace Panel or buy new Tv
Hello Give me a solution to the problem of the image being inverted on the 50-pin screen. For information, we turn on the TV with the receiver or a demo. The image appears inverted.
Sir mujhe same yahi issue aa raha hai aapne jesa bataya vese mene try Kiya last 3 block kiya par phir bhi nahi aa rahi display Walt Nahi Ata VGHP VGL VGH me Jab Start Karta Hu To.. or Jagah Pe Short Ho Sakta Hai?
Hi i have same problem with my tv short vgh in the leftside then i block the vgh going to leftside by tape ang the came up but the problem is little white ang humbars in the leftside what should i do?
Sum special cases after cutting burned track's in Cof Ic, if cof ic is at the end of the scalar pcb then image's will come, otherwise you need to change the cof ic using a Bonding Machine
Then you need to Trace out the vgh track point to the Right side cof then cut down that track, If both sides are short then not Repairable, After all it just a Temporary Solution, Permanent Solution is Panel Replacement
all videos amazing, thanks for doing this in English.. most videos on tv repair are in hindi..
Thanks for the valuable comment
Thank you for sharing your knowledge. It did work for me
Thanks for the video sir about TV repairing the information about shorting problem i
hallo bro, please advice, (the case in the same panel ) if vgh, vgl, and all test point present normally, but no display.
❤❤❤❤ good working tq
Thanks masters from cebu pi
Thank you for sharing sir godbless to you.
Thanks for the knowledge
Thanks for the Video. You instructed to block 3 signals. I assume one is VGH, the other VGL, but what is the 3d one ?
CKV
@@ElectroPixels Isn't there usually more than one CKV signal, e.g. CKV1, CKV2, ... and also the inverted clock, e.g. CKVB1, ... ?

good information sir thanks
Hi bro micromax 32 inch FHD backlight is ok ,sound ok, but vgh,vgl -0v video not display need to your support tell me clear the issue.
Thank you sir sharing this useful video
Thanks for you're valuable comments, please share this video in all of you're groups
Good and thanks master
Lovely thanks for your feed back!!!!!

Hello Sir watching from Phil.I've encouner also that kind of trouble and prrfectly fix aso like that.
Thank u so much. fix my problem. but there is still a dark spot with line visible.

you need to enter into the tv service mode to correct invert image for that contact nearest technician
Thanks bro your are a darling
Hi sir please i have innolux display in my samsung tv is it a good company in making display or no. Thanks
Good day sir,I've done the same and the result...all voltages is normal except vgh with only 23v,screen appears with vertical bar
Very good 👍👍🙏🙏🙏
Hola las señales lc1 lc2 en las tv lg como vienen marcadas?
Lg Panel its called as vgh odd and vgh even
nice video . thanks
Sir mujhe same yahi issue aa raha hai aapne jesa bataya vese mene try Kiya last 3 block kiya par phir bhi nahi aa rahi display Walt Nahi Ata VGHP VGL VGH me Jab Start Karta Hu To.. or Jagah Pe Short Ho Sakta Hai?
Nice information sir
Thanks sir
Hi sir my tv same panel which is showing virtical lines if there's any solution all voltages ok
May be Cof Bonding issues
@@ElectroPixels thanks for responding
Good job sar
Hi i have same problem with my tv short vgh in the leftside then i block the vgh going to leftside by tape ang the came up but the problem is little white ang humbars in the leftside what should i do?
block vgh track only and try
Otherwise panel change
clear explanation
Excellent
But if you have the same problem but the gate cof ic is burn what is the solution?
Sum special cases after cutting burned track's in Cof Ic, if cof ic is at the end of the scalar pcb then image's will come, otherwise you need to change the cof ic using a Bonding Machine
Well explanationed. Thanks Sir
my problem even i disconect the flexible..the capacitor in each cof still short..
Ok sir thanks 😊😊
Very good
And author scalars pcb chane oc on but over brightness so suggest
I have some problems , i've blocked the last 3 signals , picture now present , but it is like a slowmotion on the left side ... What should i do ?
Can you help me with the problems?
@@angelinajeanny8950 Same here.... Any solution for this?
I have the same problem, any solucion...
If the rightside of panel shorted how do clear short?
Then you need to Trace out the vgh track point to the Right side cof then cut down that track, If both sides are short then not Repairable, After all it just a Temporary Solution, Permanent Solution is Panel Replacement
greetings one hobby😙😙😙😙
Nice sir
Best video
Nice good help me my tv is on
Glad I could help
