I have a mitsubishi 60inch
You will need to replace IC8c00 (STK 393-110) . This is your convergence IC. You will need to measure all of the 6.8 ohm resistors, replace as necessary. These resistors will have blue,gray and gold stripes, there may be sixteen of these. Expect to replace at least three of these if not more. Replace caps C8c05 (25 volts at 100Mf),C8c07 (25 volts at 100Mf). Other caps to replace are C2c86 (25 volt at 10Mf),C2V17 (25 volt at 10 MF) and C601 (350 volt at 1 Mf). you will also need a keen eye to resolder connections behind tuner TU1A02 (says RF). Jumper sockets CE,RG,DM,VU,DP,EL. Check and resolder socket connections KC,KB,AV1,AV2 and resolder IC 2p30. And you will also need to pull the power supply board, resolder jumper connections CE, RG, DM, VU, DP, and EL. Resolder the vertical IC , this IC will be of the LA78XX series,(do not use excess solder and short the pins). Resolder the horizontal transformer, and the flyback transformer. You will need a keen eye to visually inspect bad grounds on power resistors,horizontal transistor, horizontal output transistor any any and all regulator transistors located on heat sinks. This may seem complicated, time and patience will repair this. Spend an hour a day for two weeks to fix this. Thanks for asking and show all hands of support!
