Mitsubishi WS-55807 "Bow-Tie" Problem

I have Mit WS55807 about 5 yrs and I do have a problem with my tv about 2 months. It is experiencing the "bow-tie" effect, where the (in my case) the red and green is off, and squezed in the middle. How can I fix this problem by myself?

If your not a tech, its highly advisable to not even open the set because of the high voltage and x-ray radiation issues. Now if your a technician ,you gonna need to get a service manual, Look up the convergence circuit, Find the two or three convergence driver ics, find the b+ feed resistors to those ic, and order the exact replacement parts. if you dont replace all at once, and with exact replacements, you will be in the same boat a few months down the road. This is not a repair a handi-person should consider doing as even if you get the ics replaced, your gonna need to do some minor or could be major convergence alighnment and your gonna need a cross hatch generator to do this. This repair should cost ya about 300 to 400 bucks? Sorry man Good Luck

Mounting motherboards without brass or nylon standoffs


Usually the brass stand offs are used by the slots and ports to provide a bit more solid support. The problem when mounting directly is that you don't want anything on the board touching the metal that isn't supposed to. Usually they will make mounting pads around the holes. These keep the board from shorting out. Without seeing the case all I can tell you is to see if the pads are the only thing that are touching. If you are not sure then just get some electricians tape and put a piece over the case mounts. Thats is faster and works as well as using the proper brown insulating washers. Just check first and tape and you'll be fine.

Mitsubishi vs 60719 - Wavy bow in picture


Either a bad solder connection on your convergence module or a bad convergence IC. Repair costs will probably be in the $350-$500 range.
