Question about Standard (CRT) Televisions
Television stopped showing the picture. Only have a thin, bright horizontal line in the middle of the screen. Do you know what causes this and what parts will be necessary? The TV has a manufacture date of 1989. Thank you.
SOURCE: stationary horizontal lines
Thjeres a problem with the screen voltage driver voltage capacitor or the crt is going bad. have the shop test the b+ on the crt board first off . then remove the crt board and see if the voltage comes up. If it does the capaicitor is bad as it can take the load. But remeber theres extremly hi Voltage inside these sets so its never a good idea to try to do this your self unless you have the training to deal with HI Voltage and the proper saftey and test equipment. Good Luck

Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.

you need to replace the electrolytic capacitor in the horizontal section of of your tv sets,cause the capacitor is weak.need to repair

Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.
