At first it was lots of horizontal lines over the screen, and later TV screen went completely black. The sound still is perfect. Perhaps I just need to replace the fuse? I love this TV! Thanks...


Hello
You have stated that your TV has a lot of horizontal lines before it went off picture. We say that lines as retrace lines. So many of them will there on the entire screen, at about one inch or so apart, horizontaly scattered along with picuture. At that time, you may be unable to down the brightness control also. Even though you have reduced the brightness control to zero position, there will be some brightness level on the screen. You should have to repair that fault at the begining. There is a voltage going to the picture tube base, known as screen voltage. That voltage determine the emission of the picture tube, and we call it a bias voltage. When it goes higher than normal, this trouble ie retrace lines will occur. In long run it may spoil the picture tube itself. I don't know what the case of yours.
Anyway it is best for you to consult an experience technician in this case. Ok.

CRT TV with only a horizontal line through the center of screen.


Hi,

Yeah. Unfortunately you are right. It is normally the ic that controlls power to the gun. And it is expensive.
Your only chance is to find another model of the same TV that some is ready to trash or throw away at low cost and that TV having some other defect. Advertise in the local newspaper or other channels. It is worth a shot.

WD-52525 screen is jumping all around with wavy horizontal lines etc.


Good Day;

Keep talking to the factory, it is their product. Best Buy won't replace unless it is deemed not repairable and/or terms of the contract. You purchased the extra warranty because you most have felt that the TV might break down. Well, it did, now use the contract to repair your TV.

Good Luck, big IRISH.

No Blue. Horizontal Lines.


Not to me, but it also depends on if you could do this yourself or not. And the area you are in sometimes is responsible for the cost being high.

Green screen with almost horizontal zigzag lines


Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
