    Is it very dangerous or hard to replace the IC's? Where could I buy the replacements? A local shop said they would come to my house and repair it for around $300. Would I save significant money by repairing it myself?

Your symptom sounds like a damaged convergence IC.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

If your colors line up in the middle of the set and at the top but the picture is concave then you may have a faulty component in the pincushion circuit. If the top and bottom are the only things that are wrong then it may be just be the top and bottom pin cushion circuit.

You may want to consult a Television Repair Technician, or repair this yourself. If you want to tackle this yourself, let me know, I can give you some direction for the repair

I hope this information allows you to resolve this issue.

SONY PROJECTION TV MODEL # KP-51WS510.


If the entire screen is curved, and it is not taking the whole screen, then you have a vertical deflection problem.

If the colors are double and do not match, with lines of different colors around pictures , then you have a convergence problem, often caused by a faulty convergence board.

The curving effect can be a side effect of bad convergence, or you may have both problems at once.

Unless you are a TV repairer yourself, better calling technical support. Usually you can ring the number listed on the owner manual.

Multi-color double images or shadows and curved screen


Alrighty, very common problem on this set. Here's a rundown of the repair if you're a DYI:

With the back cover off you'll notice a set of boards on the bottom of the TV and a pair of boards sitting up over the two bottom boards. The problem lies in the upper-right hand board which is the color convergence power supply. Either replace or repair this board. The repair involves the main power mosfet (a three legged regulator on a heat sink) and two diodes next to it.

Next, the bottom right hand board needs to be removed and a fuse replaced next to the flyback. If you are versed in electronics I can detail the repair further otherwise you're going to have to have a shop do the repair.

Convergence. shadowing, arch top and bottom, red and green colors


You have a convergence problem. i see these set all the time at shop. first consult the article in tips and tricks section the fl231 fuse problem. it might provide some answer and might turn out to be a simple repair. If you do not have the convergence option under setup in customer menu then i say you have that problem.. otherwise it sounds like a convergence power board issue. if you have the options try autocovergence first and then if that fails try manual convergence of red and blue if the dont move then it will be convergence power board. let me know and ill try to talk you through it
