TV has bright horizontal line

My tv turned off an on continously. I replaced a condensor C901 and now it stays on with a black screen and a bright white horizontal line. I replaced condensor C421 and have resoldered the vertical IC. I have sound and can run channels. Can some one help?

Do some voltage checking on the ic and make sure that volages are reaching there, about 32 volts. if it is reaching, then you can change the ic there. but before you do that, check around that ic and make sure everything is ok there. good luck

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.

Black screen with bright horizontal line through center

Your vertical IC may need resolder. You may have a bad capacitor or two that created an extra warm IC and create bad grounds. So resolder and check those caps near and around your vertical IC. If you continue to see this horizontal line you may have to replace the vertical IC. And you may as well check all grounds as well. Good Luck and be careful!

The brightness is very dark. Any nightime scene

Your CRT's getting old. Plus dust on lenses don't help much. You have to open front frill (below screen) and back of the TV. Clean up lenses using dry paper towels, do not wet.
In front of the TV after grill remove center cover and locate "black box" that have 6 potentiometers on it that looks like plastic adjustment screws for philips #2 screwdriver slots. 3 of them should read "Focus" These you don't touch. Another 3 reads "Screen". Put some still image on your screen (like paused DVD movie frame). Carefully add brightness in all 3 colors trying to avoid horizontal lines appearance. If lines show up, just turn it back a little. Try to keep color balance looking at the picture.
This procedure will brighten up image but further reduce CRT's life.

In case that you posted wrong model here and you have DLP Projection TV - just replace the lamp.

Rca 32 inch tv

this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.

Won't stay on

The quick horizontal line through the center of the screen usually denotes a failure in the vertical output circuit, and that would keep the set from staying on. You would have to take it to a repair shop for repair.

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.
