Problem with Pana TX-P50UT30 - black screen

[gldiana]

Dear all, my TX-P50UT30 randomly (sometimes after 15 min, sometimes after 90 min) gets black screen, no sound, and green led still on. OSD menus are ok...
Can anyone help me to fix? Thank you!!

Sounds like a mainboard issue. Don't know how to fix it but maybe a BGA Chip is losing contact with heat.

Does it do this on all inputs?

Try heating/cooling down the bga and see if that makes any difference.

You did not waste any time. Good job getting a board so quick. Usually by this age they're very hard to find.
