I have an LG plasma that made a pop sound, and then the video went out, but it still powers on and has sound. Any ideas, or where to start? Thanks!

Re: LG DU-42PX12XC Plasma, Sound but no picture
One of your sustains most likely has failed. Check the fuses on your Y-Sustain and Z-Sustain to see if they've blown. If this TV uses IPMs on the sustains (under the large heat sinks?), it's likely one of them has failed.Last edited by capkid; 08-02-2013, 12:49 AM.

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
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 ‘fading' 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 ‘new' 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... -
This is my first Craigslist freebie fix attempt. 50 inch LG Plasma TV Previous owner said over time it was struggling to turn on, it would take 4-5 times to turn on, the one day it just did entirely. I took it home and plugged it in, I her a click, then a second later another click, and nothing. Dead as a doorknob
So I took the back off and check voltages. The power supply appears fine, I checked the VS, VA, and 5V voltages and they all measured correct, on the power supply board and on the display boards (Y and X boards). All the fuses are fine
