Your vertical output IC is either defective or needs re-soldering

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

My screen has a blue line that sags from the left side to the right. It is in the top 3rd of the screen. It is not a single thin line.


Your TV has bad convergence IC's. This problem needs a professional Tech to replace these parts. The average cost should be around $450. Call a factory authorized dealer.

I have a Mitsubishi CS-3125R that displays a horizontal line with sound. I suspect the horizontal transistor is out and cannot find one. Any ideas?


You are misleading yourself. When you have a horizontal line across the screen it means that the vertical circuit is not working. You see, the vertical circuit moves the beam up and down which is not happening. The horizontal circuit moves the beam left and right and it is working. Your set probably needs a new vertical output IC and some electrolytic capacitors that work with it. The caps dry up with time and harm the output IC.

there is a section in the tv working just to keep the screen fitting top to down (vertical section) some capacitors are dry now in that area. this one has not to be a expensive job in the workshop. Try estimates

No Picture On Screen


it sounds to me like your tube has gone , go to your local tv repair shop and order a new tube its quite cheap to do so and they should be able to get it you quite fast.

The Picture on my Mitsubishi vs-60805 "shrank" then disappeared


it isnt worth it, your verticle diflection is out, that board is about 3-4 hundred, and you would probabily need a service center do it(messing with like 30000 volts)and they will probabily charge around 200

That sounds like vertical failure. Does the blue line run across the screen from side to side? Try resoldering the vertical output IC and see if that straightens it out. This is sometimes been a problem with that chassis. Let me know how you make out or if you need additional help.
