Philips 47PFL5603D/10, loses picture after about 50 minutes

[Nicholas]

Hi guys.

I have this Philips 47pfl5603d/10 LCD TV that loses the image after about
50-60 minutes. Sound is still there only image goes away.

I just opened the set, all caps on the PSU *looks* okay. I just wanted
to hear if anybody else has come across the problem before?

Thanks,

Nicholas

is the backlight still on when the picture disappears?

Hamie, it seems that the backlight is on, and only the image on the panel goes away.

Worth monitoring the voltage supply to the T-Con board....

Does the sound remain OK?

Hi, yes the sound is still present! Also, menus are gone as well,
so complete image loss.

I can see the T-Con board only has one cable running to it (attached picture)
from the main board. Could this still be PSU-related, or maybe main board?

Thanks,

Dunno--Check the voltage on the fuse of the T-Con when fault present--That will tell you whats what....

Voltage OK--Check LVDS signals with scope....

Hi again.

I ordered a new T-Con board, and that seem to have fixed the problem.
However, the new board wasn't 100% the same version number etc. as
the older one....so now I have a strange problem Hard to describe, but
some lines has extra lines. Please see my attached pictures. There are vertical lines
between the letters for instance. The video image looks, well, like high res
scaled down to 150 lines or something like that.

Any idea if this is fixable without getting yet another T-Con board?

Thanks!

Have you tried re-seating the t-con cables? Post a photo of the old and new t-con boards.
