Picture becoming distorted at the top/bottom of the screen is due to the convergence circuit going bad, and is a common issue with big screen projection TVs.

The convergence circuits will need to be repaired, which will generally require some soldering and ordering new parts for ~$75. If you want to get a TV technician to repair it then you will probably be looking in the region of about $300 for a repair.

Here is a link to repair guide for a Mitsubishi TV. Obviously a different model, but the convergence circuits are generally the same for most makes/models - this will give you an idea of the work involved to fix it: http://www.techlore.com/article/22530/DIY-Repair-Replacing-Convergence-IC-s-on-a-Mitsubshi-TV-Set/

SOURCE: bad picture at the top and bottom

If you're not a professional TV repair person, the following information is good only for reference. If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. You will need to change the Stk convergence amplifier Ic's. You will need to check for the proper Ic, but it might be an Stk 392-110 (Q751&Q752). These Ic's fail sometimes due to lack of heat sink grease, and also because they expend lots of heat. Good luck

I have the same problem with a 61uwx10b. I


the ics could have been defective, or maybe you missed a resistor or something. the ics could short out and cause the tv to totally shutdown if dead shorted, as some of these have no fuses. I would doublecheck all your solder connections and make sure nothing is shorted out and look for other bad resistors. here is my tutorial if this helps

Tv is messed up


I got a question.

Do you have any stereo speakers anywhere near your television?

This sounds like something a magnetic field could cause from speakers being too close to the tv.

If so try to relocate them and see if the problem goes away.
