Schematics for PSPU-J704A for an LG tv?
MarkZ:
Hi.
I have a LG 42PG6000-ZA. (Manufactured 2008)
Sometimes it starts full up but lately it gets stuck more than not in blink mode (red/green on power on) and increasingly so.
It does so even when it hasn't been on for a day.
When it actually starts it works fine for hours (til I turn it off).
I exchanged 4 pieces of 3.3mF capacitors that was bulging on the PSU board, but no change.
Anyone has a manual for that model or an idea where to look next?
Thanks, Mark
Edit:
Changed the headline.
MarkZ:
More info:
I replaced the capacitors with red circles because they were bulging.
Now I noticed that the component in the corner (blue circle) looks like it have been warm.
It says VA101. What is it and how can I tell if its broken?
MarkZ:
Is there an easy way of telling if it's the PSPU-J704A (PSU) that is broken?

hi, mark look like a varistor, you can heat them up and test with a mulitmeter, look on youtube

MarkZ:
Thanks for your answer.
Now I'm looking for a schematic for the PSU so I know what specs the component have, to exchange it.
Any ideas where I might find one?
Br, Mark
