Is it me or does it click slightly on each flicker? Can you hear that? If so, try to narrow down the source of the noise, that may be a good place to look. Take the cover off the unit, and take some good clear pictures.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I picked up this TV that the prior owner said - just died.
Tested the fuse - burnt. A dead capacitor is visible too on the hot side (CP801). Got the replacement power board (cheaply - used). Replaced the board - the TV turned ON!
Now, about a month later (yesterday) I noticed the left side of the screen was flickering from time to time. That was already happening with the antenna input, not through HDMI.
Also, some glitchiness with a Fire stick on HDMI3 - I hit an app with quick dark screen in stick, the TV goes - no input. Then I had to choose the stick... -
Saved this beast from the landfill this weekend.
Manfactured July 2013 in Mexico.
I love working on plasma TVs.
Its been a while but I was lucky enough to find 2 this week.
The TV powers on and stays on but no picture. Havent checked for sound yet.
No bulging caps although the insides are pretty dusty and the boards are discolored from many years of high heat.
Will start troubleshooting tonight.

Hi all,
A few weeks back my plasma lg tv developed a flicker along with a red line across the very bottom if the screen.
The line appears to of disappeared but the flickering persists.
I have included links to a couple of videos.

I studied electrical engineering at college and build pcs but this will be the first time i have opened a modern tv.
Can anyone point in the direction of what i should be replacing based on the videos?
Thanks... -
Good picture but has ~200Hz+ faint flicker/strobing over entire screen. Also has a single green vertical line. Can mask out t-con signals (2pins) to stop flicker/strobing but 1/12 of screen will be all colorful vertical lines (single green vertical line is in this section)
Since can mask t-con signal to disable part of the screen and stop flicker/strobing. Obviously not backlight.
Panel has 4x driver boards each responsible for 1/4 of the screen. 3 tabs on each board. Each tab responsible for 1/12 of the screen. the 2 outer most tabs has additional horizontal gate control... -
Hello,
I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
Opened TV cover & observed foll
a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
How to confirm Y -Buffer board...
