Re: Panasonic TH-50PZ80U, powers up, no picture, no sound
Should I replace both the capacitors on both the MC201 and MC301?

Re: Panasonic TH-50PZ80U, powers up, no picture, no sound
Might as well of course can't be sure this will fix it but I have had the 2 blinker and after reflowing the cap it worked for a month then quit, did the caps and all good. Never had any freeze spray so it was a punt but the fact it was intermittent then working then quit I was confident. Could be the IC but ry the cap first. i bought a kit and never used the IC.Comment

Re: Panasonic TH-50PZ80U, powers up, no picture, no sound
Hello. I have a Panasonic TH-50PZ80U as well. 4 weeks ago I had no video for about 30 minutes, but then, everything started to work fine again.
Today I am watching a show on the unit and I loose the image. The unit is still powered on and primed. Remote control access all works including power, vol, menus, etc...
I was using HDMI input but tried component and composite, with same result. I tried Panasonic plasma D board test Tom had posted but no pattern appeared.
Any ideas for next steps if D board test fails? Could I have a loose LVDS Cable?
Thanks.Comment

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture

Hi everyone,
I've got this Panasonic TV here with the following symptoms:
* Standby Light is solid RED
* Turning on using the Button on the TV (long press) would change LED to blinking GREEN
* After a couple of seconds, LED is solid GREEN and without picture or sound.
I've tried a couple of things before tearing it apart:
* Resetting using various combinations of powerbutton and volume buttons pressing down while booting.
* Activating Self Check according to service manual using IR Blaster (we have no remote unfortunately)... -
I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started βfading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly βnew' Tcon board this time, and... -
Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon...
