Hi again Davy,

Just realised it's plasma not LCD, but have no shematic with an UB801 listed. Guess it's an 8 pin S/by chip, but usual sites don't list it.

Try again in 'Plasma' as some quuq 'Plasma' folks can be 'sniffy' with LCD entries - All the best - Chris.

BN44-00237A is equal to 00222A
and here is the schema.
Look at page 3,
there you got UB801
