The flyback transformer, and some other components may have failed. The main power supply may also be damaged.

It is impossible to know the exact failed parts without trouble shooting the set.

There are some components in the vertical deflection circuit area that are failing. An experienced TV service man should be able to troubleshoot and repair this for you. It could take several hours of labour cost.

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...

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.

Sony trinitron

check the heater as your tv is ON, there must be a yellow light at the rear of the CRT tube. If the heater is ok then check the IC jungle side. resoldering the leads sometimes will solve. If not refer to your local Tech.

Sony Trinitron - Picture Disappears

Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

WEGA 36" : Screen is low contrast and green

Sorry to say, it sounds like a bad picture tube, But could be also the capacitor that filters the screen voltage on the crt drivers. In all my years though, your complaint has been the picture tube. Good Luck.
