Question about Sony FD Trinitron WEGA KV-34HS420 34" TV
Just watching the tv and the top half of the screen just went black and there is a line through the middle and there is picture down the bottom. Is this problem worth fixing and how much would it cost?
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!!

Usually when a tv is dropped the phospher screen inside the picture tube will detatch making the rainbow color This cannot be fixed as it requires changing the picture tube. Only other thing is demagnatize it with a demagnitizing coil (used by tv techs) but not likely to fix it since it was dropped. You have a bad picture tube.

Sounds like a problem with the vertical circuit. If yuo can solder and are comfortable with working inside the set, you may be able to repair this.
Keep us posted.

If hte set is a Sony, the standby light should be blinking a code. Report that code here and we should be able to guide you. That code will indicate the problem circuit within the set that has the fault.

Hello jorge and welcome to FixYa. With your particular model of television six blinks mean a Horizontal Drive Failure has occurred. If you have any television repair experience you could try checking the jungle for loose or possibly bad soldering. In some case the jungle IC was found to be defective on this model as well. You should also inspect the horizontal drive transformer windings if at all possible. If you are unable to repair this yourself I would personally say to you no it is not worth the cost to repair it as purchasing a new television would probaly be a more prudent decision. I hope you found this helpful and thank you for visiting FixYa.
