You got a weak CRT. Turn up the screen a little and the video will come on.

Subject: [TechAssist] sony tv KV-27S66 no video, led blinks nonstop


> I'm  sorry if this message got sent twice... problem with this browser
based email. Anyway, I have a Sony KV-27S66 that was blinking the led 2
times....B+ OCP. After searching I found C641 was loading down the 12v
line.... down to 6v. I also found Q601 and Q603 were leaky in the PS
section. I replaced those also. The problem is, now with the new cap in
place, I have audio but no video and the led just blinks non stop. When you
first turn on the tv the relay kicks in and you can hear the HV and the
audio comes up but the led just keeps blinking and the picture does not come
on. I have checked all the voltages and they are fine except one....TP504,
it should be 200v but I have 156 volts.  I have spent a lot of time on this
and would appreciate a little help so I can move on....
