Hi Westfield1,

Don't have it listed - who made it  ? - Some piccies, maybe - Chris.

PS - Sounds like duff caps, warming up perhaps  -

westfield1:
Hi Chris, i dont really know who made it but it has got a vestel 17pw20.1 psu board when i got it it was completely dead but now its got this  fault it happens about 1 in 20 turn on's i thought a bad cap but without an esr meter i will struggle to find it as all the caps look ok and read capacitence ok.

When it happens i get sound and thats it and it will stay like that until you turn it off.......Paul.

Ohm Supplies:
paul.

Do you get a backlight or just sound only?

Is the 24v present from the psu when this happends?

regards
Andy

Hi Andy, no backlight i have not check the 24 volt, when it happens i get only sound if you put a torch to the screen i cannot see a picture so i am asuming no backlight, no picture just sound....Paul.
