SAMSUNG HG40ED450BW Striping Picture
MAIN BOARD BN41-02217B BN94-08383W
POWER SUPPLY BOARD BN44-00754A
Power board has steady 12.1v . TV works normally for about 30 mins, then has striping at the bottom of the screen. Heat sink on the mainboard feels hot. If I turn the TV off and back on again the striping is still there. If I wait until the heat sink is cold, the TV works normally again for about 30 mins. Any help would be welcome.

Picture looks stretched out and it looks like every other vertical line is not being drawn though hard to see that in the pics.
I've disconnected each half of the panel and the fault remains exact save for the disconnected side being white.
The original complaint was the tuner stopped working so the main was replaced however the new and old board exhibit the same picture defect.
Nothing is getting hot and pushing on the panel drivers effects no change in the picture.
So with that does anyone know how to enter the Service Menu on this... -
Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.
The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

First replacement T-con:
I thought it might be t-con and ordered new t-con from china(supposedly tested)... -
Good morning everyone.
This time I have a Mitsubishi HS-E82.
It was a bargain that I found with original remote included.
The problem reported by the owner is that it was working but no output video.
I took it appart and immediately saw that three 470uf capacitors were leaking on the signal board and one in the Hi-Fi board the same value too. I have located them in the pictures in red marker.
I replaced them, cleaned all the liquid remains and the video output got working again.
I saw too that were three surface mounted capacitors, two near the 470uf and... -
This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.
Problem
TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...
