Sony Kv21Se42 stby light displays 4 blinks.

[SEAWOLF]

I recently replaced 3 elec capacitors in the vert circuit of a Sony Kv21se42 with
the stand by light blinking 4 times.When the tv was powered up,there were
vertical lines on the screen and I replaced the ver IC and the television worked
ok for 3 days and shut down again and stby light is blinking 4 times.
Can anyone offer a solution for this problem?

I would check the Hor Osc cct for cold solder joints, also. Hor Osc Transformer, transistor, Horiz Output Transistor, Horiz Osc IC, etc. Ther may even be a Hor Osc Crystal that may be faulty.
