For that type of problem you will probably want to call a local tv repair shop and set up a service call. Average price is 60-80 dollars to have a professional check the set and provide you with an estimate. To me it sounds like maybe the vertical circuit has failed if you have colors across the center of the screen. Also there is probably a resistor and capacitor that need to be replaced on this one. Usually it is a repair that most shops will be able to handle for less than 1/2 the value of the unit which is the breakoff point for most people. I wouldn't suggest trying to self diagnose this one without test equipment. Good luck, Russmann..

From reading your question i have decided this isn't something you have any hope of fixing yourself. Take the TV to a service center/technician they will be happy to fix any "vertical convergence" issues you may have.

Sounds like you're having vertical problems. I saw the vertical chip on this set go bad several times. Location is CN301. Sometimes you may see a big dent or even a hole in it. If that is the case, you need to replace it and check around it for any blown parts or loose solder joints. If you don't do that, the new chip will be destroyed. I have it in stock if you want it.

Samsung makes that set . They are notorious for leaking fluid onto the picture tube socket or the chassis. I do believe this is your chance to say goodby. Take it.

This is not an "STK" problem. Your problem is VERTICAL. You need to check your vertical chip for damage CN301 and check around it for any bad parts or loose connections. I've seen loose connections on the chip itself cause it to self-destruct.
