Hallo,

I think there are some dry joints in the vertical circuit.
So have a look to the IC TDA or TEA....
Perhaps you ll see your problem at once.

Also there can be more dry joints on the chassis board.

Greetings Alde :lol:

Hi,

Generally sony is well known for dry joints so Alde is right. You should consider to rework the board competely . especially you can find dry joints under the plastic frame where you don’t expect them. So be aware!
