Thin Bright line is all I got on the tube

I already paid for service on this set, different problem. The picture went "thin on me, with black belts on top and bottom. Shortly after it went to a thin white line, side to side. I threatened it with my 9mm, but it just smelt hot... kill it or what?

Sounds like a capacitor and/or the Vertical amp Ic has gone out in the set. Maybe a bad solder joint. Depending on where you live, the cost of repair could be between $100.00 to $150.00. Kill it or what? What would Braveheart do. FFFRRRREEEEEEEDDDOOOMMMM

It sounds like you have a bad capacitor in the vertical circuit. The circuit needs to be checked out by a technician. Stargazer

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

Picture is now a thin horizontal line


now only visible in a thin horizontal line. first of all you reduce brightness to monimum. it just to protect your tv from crt demage. your problem is in horizontal output section as you have mentioned that week or so ago the right and left bottom edges of the picture began to move in like a sideways triangle filled with black so this sympton is due to hor. section problem. your flyback transformer or horizontal output might be defective. but remember check for power supply is ok from surge protector hope this will help.

Top half of screen black


The vertical circuit is going bad,this is the one in charge of opening the picture up and down,try taping on the side to see if the picture reacts ,if it does your set has a loose conection and the vertical IC will need to be resoldered only but if it does not react the IC will have to be replaced,if you are familiar with tv service this will give you a place to start but if you are not be safe and seek the help of a servicer,please let Us know how it goes.

Picture went black


The good thing is you see something in the screen,with age the set has developed loose conections in a few different places,my suggesion is to call professional for service now and the repair will not as expensive,if the picture quality is good is worth it.
