I've been in the process of recapping a Sony KV-27S42. I first recapped the power and horizontal sections and it was working great. The other night I recapped the vertical section and also several caps near the jungle IC.
Now when I turn on the TV, I get high voltage but just a black screen with a constantly blinking standby light. The remote still turns the TV on and off, but I get no OSD or picture. If I turn up the G2, I can see retrace lines. I can't test if the sound works, because the sound stopped working on the TV a while back.
I double checked that all the caps I put in were the correct value and polarity. I measured the cathodes and get 200v on each one.
I looked for cold solder joints but didn't find anything obvious. I reflowed several points just to be safe.
From what I read in a Sony training manual I found somewhere online, a continuous blinking standby light means no jungle IC communication. Is the jungle fried?
