Sony Trinitron KV1926RA No HV
Hi! I found a Sony Trinitron KV1926RA TV set from February 1990. It had been out in the rain for a short period of time, then dried. A few drops when I first plugged it in. It's really cool because it has a "SIMULATED WOOD" sticker on the side, haha! So, of course, it didnt work so I took a hair dryer and Q tips to the motherboard, and dried and cleaned it. Now, the relay clicks on/off normally but no picture and I can't hear the flyback! What can this be? On the main board, there is a fuse for the flyback I think, and its OK. The big mains fuse is a little white on the ends, but I think its also ok. The big cap was bulging but turns out it was just the plastic cap expanding. Thanks!

A couple of days ago I finally got my hands on a locally sourced Trinitron and after lugging all 175 LBS home I gave it a good cleaning inside and out. The guy said it had been in a shed for 2 years, but the outside wasn't too bad. The inside was another story and while there was no evidence of mouse, it had certainly been kept in a VERY dirty home.
I cleaned it to an acceptable level of grime, at least clean enough to where nothing would heat up from the dust insulation. I then tried it out and it worked!
I'd say I had it on for about 15 minutes or so and then lugged... -
Hi everyone, I've been troubleshooting my 20" Sony Trinitron (KV-20FV12) CRT after it failed to show a picture. The standby LED is blinking 4 times, which according to the service manual is a failed vertical deflection via the self-diagnostic check during power up.
After getting the TV checked out by a technician and doing research on my own. The most obvious first step was to replace the IC502. I've done so with an exact NOS replacement with no luck. I've read a few suggestions to make sure the 12V supply to pin 2, but that voltage check would seem misleading? It seems if the... -

This is a CRT I sold a few months ago and it's came back with this weird issue. It's intermittent, but not a thermal fault, or tap sensitive - just completely random. The right side of the picture completely blanks out (picture is not shifted). The on screen display is unaffected though, so not a fault in the line section. Anyone seen anything like before in a CRT?
