No sound is probably because you're not on the right input but the horz line is a failure in the vertical circuit. Could be the vertical Ic itself Ic401 (LA7833) or the feeder caps just in front of it... In either even it in itself not an expensive repair. Be aware though that's an old unit and it is likely that several caps going bad through-out the unit. Make sure that you ask the tech to go through the unit with an ESR meter and test all the remaining caps in the power supply, horizontal, HV and regulation circuits. A little preventative and that set will still be running long after I'm dead and gone...

I have an old mitsubishi TV model cs 35203 serial 515512, and all that shows up on the screen is a thin horizontal line through the middle.


You either have a cold solder connection on the vertical output IC401 or a failure of the Vertical output IC altogether. The part number should be labeled clearly on the front of the chip and is likely LA7836 or LA7837. It's difficult to reference parts on a set this old. Remove the chassis and visibly inspect the solder connections. If they look good, replace the chip. Good luck

We had a blue cone on the screen. We have adjusted the sharpness, contrast, and cross hairs. The cone has almost completely disappeared, but we still have blue shadows. Could this mean a blown color tube?

Any suggestions would be greatly appreciated.

Picture has horizontal lines that move to middle of screen........


Just got this fixed. The problem is the 21 (yes, 21) main capacitors. It'll only get worse if they aren't replaced. The whole screen'll start jumping, multi-hour "warm up" times until you get a clear picture, maybe not even then... it isn't pretty. Just nip it in the bud now, and more power to you if you tackle it yourself. A good repair shop ought to be able to do this for under $400 if you can't.

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.
