Philips 32pfl6306/v7 LCD picture freeze

[zewarrior]

I have a Philips 32pfl6306/v7 LCD TV bought ages ago very sparingly used, probably a maximum of 20 hours. The TV works fine for 15-30 minutes when switched on and then the picture freezes with vertical lines but the sound works. If i switch of the TV and switch it back on again after some time it works fine again for 15-30 min and then the problem repeats. Can you please guide as to where the problem might lie.

Heres what it looks like -

Hello
This 6000 series is for the Indian market.
Therefore I can only guess what is installed. Is it a Q552.2ELA chassis ??? Then the Tcon RUNTK4593 could be installed.
Please check.
Greetings Thomas

Hi,
I dont have the tv open so cannot confirm the chasis number. Where exactly is it mentioned? Went into the service menu and got this info -
Model Name - MTK 5301B
Version Number - MTK5301B-4.2.7-2011825
Is this of any use?

Sorry but I need a picture from the nameplate and if possible a picture without a back wall. Then I see what's installed. MTxxx are the chip sets.

The video is not clear, better to post a variety of images.

Please see attached images....red and yellow markers indicate vertical lines being formed when the picture freezes. Theres a horizontal blue line also which forms at the bottom of the screen. Sound works and channel changes work too, but picture is frozen. Im assuming some IC starts misbehaving when heated up as after giving it a break the TV works fine for 15-20 minutes and then same thing happens again.

I understood earlier but couldnt send as the TV wasnt hooked up. Have reattached TV and taken pics. Pictures here are when the TV is working...see bottom part of screen.

Can we see the internal of the tv? Maybe there's a FRC with a failing regulator like the Philips i own.. If you are familiar to read schematics i think you can find them, locate the various regulators and check them in the moment you turn on and when it freezes.. otherwise post big pictures without flash of the frc board and the main board.
