LCD L32X10M2 menu OSD OK but no picture!

[Ahakim]

I need some help to fix the problem of a PANASONIC LCD TV:
TV on, with a source signal (from DEMO for instance): sound normal but no picture at all (i.e. black screen). TV (not demo) menus appear on screen normally...Remote control functions perfectly.
SMPS V outs all good. Would it be an EPROM programmation problem??
Information on back cover:

PANASONIC
Model No: TH-L32X10M2
Power rating: AC auto 110-240V - 50/60Hz
Power consumption: 99W
Made in malaysia.
PANASONIC CORPORATION

Many thanks...

Try doing factory reset.

VOL- held on TV.
Menu on remote. Diagnostic pops up, check for any errors.
Power off TV by unplugging it.

TV boots as if it were new from the factory.

Thanks TOM for the reply. I will try the factory reset.
Any schematic for this LCD TV?

Yes I tried the the Factory Reset, but no result, nothing has changed at all. Diagnostic says: all settings are OK. Most probably the problem could be in the video part on the main board...Don't you think so? Or should I look elsewhere? Any clues or tests that could reveal the cause?
Thanks for your time Tom...
