Repairing a TV set is actually a skilled work. If you're not sound in electronics, make sure, that you can't do it; especially to Sony sets. If the set switches ON; with audio output OK, and there is no Video, surely the fault should be with its horizontal scan output section circuit. Check that circuit for fault.

SOURCE: SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK

You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!

My remote worked fine, but suddenly won't work at all. TV is older Sony Wega 24" Trinitron (KV-24FS100). The satellite remote will change the channels, cause it's using the box, but it won't control...


Could be the IR receiver in the TV.
Make sure nothing is in front of the TV that would block the IR from receiving commands from the remote, I've seen customers put VHS tapes on the front of their TV that caused the remote to not to work.

Good luck

Sony FD Trinitron Wega Model KV-24FS 100 TV. Good morning from Arizona. The set is connected to Direct TV, and I use that remote, except when watching DVDs. A few days ago, the screen went blank, and the...


Hello,

The 2X blink indicates that either the Horizontal output transistor is shorted, or the RGB amp is shorted (on the CV board).

The Horizontal output is probably the cause, and as a general rule, the flyback should be replaced along with the H-Out transistor. Good news is that Sony is pretty good about having parts in stock. In fact, a lot of times they will have the A board with all the parts on it for only a few bucks more than just the flyback, so you basically get a new TV (electronics-wise).

Any decent repair shop should help get the parts/do the repair for you if you don't have the electronic experience.

Hope this helps you...
