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?
Thanks and excuse me for my english.

Bye.

Usually just below 200 volts; adjust to lower the voltage until the speckes
disappear. If no change, return the adjustment to it's original position.

Just exactly where this is located in your unit I don't know. In Samsung
models it is usually in one corner of the Y main board, near a Vs test
point.
