Sony Trinitron tv - Model: KV-T25SF1

KV-T25SF1 PROBLEM

I have this model tv,its problem is that it turns itself off or returns to standby 5 seconds after being turned on.

I suspect a power surge is to blame.

can anyone help point out what is to be replaced?

I have replaced all the capacitors in the power supply

regards marc

  Hi, I am having a similiar problem. My tv will not turn on at all with the remote, and if I turn it on with the power button it will just cycle through on/off about 10 times. We have ours connected to a power surge cord. So I am under the impression that we were protected from surges. Let me know what you find out. This tv cost of a small fortune, and I really an not currently in the position to purchase a new one. Man this stinks!
  Thanks,
  Melinda

    Not too sure what you mean,suspect your picture goes bright and then dark,check all connections and components on CRT board.
