Vertical section problem

To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

Capacitors failure at vertical deflection section.

go to the vertical section n change caps like 100uf, 2.2uf around the section in addtion check some caps in the line o/put like 22uf 250v

Sounds like vertical problems on your circuit board. Unless you have some electronics experience you'd better take it in for repair.

The inside of a tube TV contains high voltages even when off and unplugged.

Hello dacrewof6,

This sounds like your vertical section is malfunctioning. This can be caused by the vertical drive section which connects to the yoke transformers of your CRTs. I would suggest taking the set to a qualified repair shop and having them check the vertical section of the TV.

I hope this helps

Thank you,

replace cap. 2465, cap. 2561, cap. 2460, and d6460

hi there, you have vertical section prob., repalce imeditely the electrolytic capacitor at the vertical section. do some test and check up. ty

your problem in vertical outout section only. check feed back line. most probably electrolytic capacitor failure.

This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.

Hi you have lose solder in yor vertical section have a tech resolder it or that problem will cost you .hope you have already have it remedied.
