Lost color - Mitsubishi WS-55511 55" Rear Projection Television

You have several bad grounds on the convergence board. Boy! I mean several and to numerous to mention. If you know which is the convergence board, pull this out of the TV. This will be difficult and requires your best patience. The convergence IC is located on a large heat sink. The IC will be an STK 393-110. Start by re soldering the pins on this IC. Check all resistors that are 3.9 ohms at 2 watts for values with a DMM. I do not believe these will be need replacing, check to be sure any way. You may have to re solder these as well. You will note you will need to re solder the jumper jacks (these connect to boards on either side of the one you are working on. Locations of these jumper jacks are PM, VU, and PF. Now if you can, inspect the rest of the board, and look very close for solder breaks on diodes, transistors, capacitors, resistors and transformers. You must really look close to find these. Don't expect to do this in one day. Spend about thirty minutes a day for week, for inspection and corrections. Thanks for (yawning!) asking me and show all hands of support! G'dnite.
