Hi there :-)
I have this Prosonic 30 LCD TV-B-30 with a Beko LB-6 mainboard inside. The mainboard version is Y51.190-05.
No picture, sound is okay and all power supply voltages seems to be okay.
When switching on the TV by the power switch or RC, it turns on and stays on. But besides a quick "flash" on the screen it stays black.
Any ideas? :-)
Kindest regards,
Karsten
