I wish I had seen this about a week ago. I just got tired of messing with my Sharp and it had the same fault and symptoms. I had replaced the backlights because I had the one long one short fault code to begin with and it worked for a bit then went into the fault mode like yours. I also had a quarter of the screen stop displaying right before it happened. I couldn't find no info and got tired of troubleshooting it and ended up just breaking it down and giving up. Thank you for the info though because now i can locate where i put my power supply board and repair it and maybe sell it to recoup some of my loss. I know they want an arm and a leg for the boards in these tv. Good find bro!!
Mr. Ray speaks the truth. Seems to be a common problem on this model power supply board. Same fix for a a 70" LC-70LE847U Sharp Aquos. In my case, the power LED was 2 slow and 5 fast which indicates display (panel) fault. Normally fatal but having nothing to lose I checked the regulator anyway. 8.4 volts on pin 2. I want to say I got the replacement KA378R12 off eBay but not sure, anyway they were 2 for around 10 bucks shipped. It's a readily-available part; look it up on Google. Make sure to remove the old thermal paste on the heat sink and apply new. Don't overdo it, a light even coat on the back of the part is fine. The TV's been running sweet as a first kiss for a year or so now. (I got it free off off the local Craigslist) 10 bucks well-spent!
Excellent I have a similar tv with the same symptoms and started to doubt in my theory and internet start to convinced me that was TCon board, but thank your video now I know i'm not crazy
I will send you one litre of vodka if its Voltage Regulator on my TV mobo, almost same model, exactly same led flashing sequence. Just got a TV for free. Taking in my hand screwdriver to check tommorow. BR from Poland.
I have a similar issue with a lc55ub30u i just picked up off Facebook for free ordered all new boards for cheap off ebay I'm praying to jesus that after i replace all the boards it fixes it it's not hard to replace the leds i just don't want to have to resort to that and i truly don't think they're dead as I'm not positive but i think when i was tinkering with it they came on briefly at one point then shut off so I'm pretty sure it's power related
@@rays.2480 im pretty confident it is the power board aswell as the leds plug into that and the power light comes on so I'm hoping the boards fix it if they don't idk whats going on i think it's unlikely that its the lcd itself or backlights but i could be wrong
Mine is aqous LC-50LE570X it has red standby and blue (switch on) but still no display no backlight no sound I tried to check the output voltage on standby it starts on 9v slowly going zero...do u have some advice for my tv?
Hallo there I hope u still here I also have a sharp but mine is the model LC-60LE635E It looks really similar to the model you have, the power supply board is the same and I have the same issue, no sound and no backlight. On my tv it blinks two times maybe I'm Lucky as well and have the same problem. I'll check the the four pins and give you feedback. Thank you for the video!
Hi Ray, where did you find the a KIA378R12PI ( 12V Regulator with turn on control ) I have ordered two sets of regulators these are not the turn on control regulator? Can you please provide the manufacturer where you purchased your regulators? Thanks a million!
Hey what’s up man how you doing I had the same problem I got the same TV the only difference is I get sound but it’s a flashing light no picture I want to thank you have a blessed day
I have the same model... I've been having power freezes (power light on, black screen, no response to remote) for years...backlight has never functioned...but no flashing or error code... I have to unplug it, wait 10-15 minutes, then plug it back in... Assuming that It needs that time to disapate the charge... Do you think it's the same regulator causing it??? Thanks for posting this... :)
Hi Ray, thanks for your video. I have the same Sharp model... it's been an excellent TV, until recently. I was wondering if you or your readers have any experience with this model, regarding local digital channel reception (re: antenna)... We don't have cable (for channels), but currently are using internet sucessfully for internet channels like UA-cam.... we cannot any longer receive any local digital channels My Sharp will no longer receive any local Digital channels (have done several resets, as per set-up, which has always worked in the past. I'm getting an error message "remove scrambled channels", which we never had this message in past years.... is there a digital tuner chip in the TV that might be defective?, or is this scrambling new? Thanks The antennae, cable & transformer have all been changed,
sorry i cannot answer any of these questions, i do not have this tv any more, it was just a repair that i showed.. there was no videos related to the issue i had, so i shared what i did. if you have no power, then you must check all the regulators,, you must have a schematic to follow and test.
Hi I have Sharp Aquos LC70LE650U, I already change the power board what you did but still same flashing I get. Do you have any idea what else the problem is?
Hi Ray Thank you for the video I have the same TV model and the same symptoms unfortunately we don't see how you changed the regulator in the video is it possible to make another video where we see you change it as is it possible also to confirm the technical name of this regulator so that I can buy it online otherwise if you sell it it will be cool
@@rays.2480 thank you for your answer I checked all the comments but I did not find the regulator designation please give it to me please I will look for it on eBay
Good morning Mr., please I need a measurement if you have a A6069H chip of a tv SHARP between pins 7-8 and 3, I have 5 pieces and between those pins there is zero ohms, I want to be sure of that measurement to return them. Thank you very much.
Hello Sir, my sharp LC-60LE640U just has a blank screen with sound , I can see the screen get brighter when I change channels but still a blank screen, could this be the T Con board?
Hi Ray, thanks for the video. I realize you may not know the answer to this, but I appreciate that you are taking the time to respond at least to other questions.. I am wondering where that turn on voltage, pin 4 on that regulator is getting its 3 volts from? That seems to be the problem with mine... I have 12v on pin one, but only millivolts on pins 2 and 4, I changed out the regulator thinking it was at fault, but after researching your video a few times I think I’m understanding that pin 4 needs to be getting 3 volts from somewhere in order to “turn on” and send voltage out of pin 2... is this correct? And do you know where it should be getting that voltage from? Thanks again!
Check your other voltages on that board. You should have 5V standby voltage for one on another white connector and others. You could also trace the circuitry back to see where your missing voltage on that pin comes from. I wish these videos would show the schematic, if possible, so we could follow the voltage paths.
Hi I have ah sharp aquos lc-55le620ut model do you have a experience to fix that no power no blink but I try to test the supply have voltage and suggested pla thanks
i could replace the regulator, but i have no way to test the board afterwards. as i have said in previous post.. I no longer have the tv..it was a customer repair.
I have a sharp aquos lc-60le550u and it looks identical to this and doesn't seem to have a backlight even though the panel comes on. do you believe this is the same issue and should I go ahead and purchase the same resistor? I don't have much experience but i can go buy a solder to make it happen
Thank you for this video. But I do not have this issue, my issue is I get a box saying 'Unfortunately, TIF Test is not responding or working' and "AquosTV is not working or responding". I would like more information on how to get this working or removed. It interfers with tv channels with antenna, no cable. Does anyone else have this issue? How to get this working again?
Just curious if you have the schematics I'm looking for a couple of diodes on a dps167 cpa ...at d7202....d7201 looking for the part number cross reference number something I could find in the United States
hi i have the same tv whit the same symptoms did some power tests and i have the same as on you video by any chance you have one of those regulator ?can i buy it from you ?? i only found them from china delivery estimated February 22 thank you
Ray S. Thanks anyways I just figured I would ask just in case you may have remembered, I have looked everywhere with no luck , guess it’s time to replace a 5 year old TV again ugh!
I Read somewhere you have to enter service mode and reset error codes, press volume - and input then connect to power while pressing buttons, wait till the tv turn on
No, I had to order it, I got a few of them, they were cheap. I did my typical testing, found out which voltages were missing, Which happened to be my 12V regulator. Found it, Looked it up online. I was able to use a common regulator for testing purposes. The proper regulator has an on/off control. With the common 12v regulator, the set worked fine. But you could not control the functions of the tv to turn it off. So, when it worked, I then ordered the proper regulator, installed it, and the tv was good as new. An easy job for someone that has electronic experience. Not a job for an amateur.
@@rays.2480 i tried the VOL down, Channel up, and power button at sametime to bypass the blinking and it works, so now i have steady light, but i have no backlight now.

Thank you sir sharing idea 👏👏👏👏
Hi very informative great video have the same problem have to source a regulator thank you.
I bought a few off of Ebay.. Easy part to find..
Nice fix
It would be nice that you show how to change the regulator, for next time. Thankyou.
it's really easy if you have any electronics experience.. just desolder the pins and undo the heat sink.. nothing to it.
