Hi, I have gained one LG based Plasma TV set.
This TV is maked around model 42V5 chassis.
In dark scenes, I see high quantity of green dots that is very numerous
immediately after brightness change from light to dark, then decreases if
scene persist dark.
How I can check?

Sounds like a Vs adjustment...

Ditto.

The Serviceman column in the April 2009 issue of Silicon Chip Magazine
identifies the problem as a V Setup adjustment. FWIW, on the
PDP42V72462 chassis it is VR1 on the Y Sus board.

Thanks to all.
If Vs and VR1 adjustment does not solve the problem, is it possible that
this is an electrolytic capacitor failure?

Thansk.
