Try reseating all the connectors
Hi TV gurus.
My mates plasma has sound but no picture.
I've had a look in side and checked the two fuses on the PSU board.
There are no visibly stressed parts.
I know it's not much to go on but any advice is welcome.
I've downloaded the service manual.
Thanks.
For most of my life, I lived a delusion

I'd start with checking out the Y sustain, buffer boards and zsus for failure

Hi Bibliophile,
did you fix your tv?
i have the same tv and problem
cheers
Check Va and VS first If they are good check -Vy on ysus usually across a resistor.If it missing it can mean buffer board failure.If still no -Vy ysus faulty.Some later LGs drop Vs after 10 seconds and if there are no shorts it can be real hard I mean tech support cant help you.
