Beko L6-B, no picture
« on: October 11, 2011,18:29:38 »
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

HI

Sounds like the inverter is faulty, try feeding the scart out to another set and see if you get a picture

Remove the inverter nd have a look for signs of distress or bulging caps etc

Hi Karsten,

What inverter, should you need it and if Scart out is OK. Some Quuqer might have one - Chris.

Hi Brian,

You were right! It was one of the transformers on the inverter board. I've ordered a new one. Hopefully that's it :-)

Thank you for tipping me! That was very helpful.
