Hi,

On this model flashing 2 times means either +B over current or Vertical
output stage failure.

Disconnect D505, the set will now come on if it is vertical output failure -
if so replace V-out chip.

If not, the problem will be over-current which usually happens when the
flyback transformer fails.

Philip
