Hi, I've got this lg model with the same problem and at the time it was to expensive to repair, but after watching you I can at least find out what the issue is and if the parts are now cheaper then fix it. Thanks for the video
Hi. Thank you for an excellent video. How do you check the MOSFETS and Diodes on the Y Sustain board please? You omitted that part from your video. That was the part that I was interested to find out how to check the transistors!
Excellent video. Thank you

Hello,
I have a L G tv with no picture. I watched your video and I think it
is the capacitors. How ever when I was trying to figure out the problem(
Before I watched your excellent video) I changed the Chanel on the T V
and now can't get it back to CH #3 or Ch# 4. so now I have no picture
and only static sound. I tried using the remote to command the channels
to change but no luck. I have the skills to change the capacitors, can
you tell me how to get the tv back to #3 or #4 ?
Thank you,
James Ferrigno

Hi, is the tv turned on or is it off when you`re checking those voltages?
thanks
I have a 50in lg plaza tv can see the screen light come on but remains black no picture no sound nothing when I push menu button any help just want to change the whole board if someone knows with one
Hi all, maybe somebody here can help. I was given a 51 inch Samsung
Plasma TV model PN51D530A3F. When I turned It on It would "tick" from
the "power board" and I traced the problem down to the "X main board".
On the "X main board" I replaced 2 ( RPJ30H1 transistors), 4 ((30G124 transistors) except I used (30J124 transistors)rated 170v higher) and 2 ( SF10A400H) diodes.
After replacing these parts the TV came to life but now for the problem.
The "X main board" gets so HOT that you can barely touch the metal cover on the back of the TV.
None of the Caps were bulging ,should I have replaced them and would replacing the Caps eliminate the very high temperature.
