First you need to determine if the convergencecircuit has failedWhen you got to Convergence on the customer menuthere may be two options1)auto focus and 2)manual adjustOlder mitsubishi's had the red/blue horiz/verttrim adjustments under the front door to the ritghtYou need to see if the Red and Blue move up and downand left to rightANY failure to move in basic crosshair mode meansyou need a repair to TVSometimes the colors move but dont fill the screencompletely an area appears like its rolled over on itself leaving a hollow zoneSometimes you can adjust the picture to normal looking but it distorts right after you save the changesReplacing the 2 IC's which are usually STK-392 typeis usally a temporary solution in most cases there isa reason the IC's failed. In Toshiba its a few 100uf capsIn Hitachi its the IC's but resistors also fail when the IC's doGet yourself a decent Projection TV Repairmanand let him complete the repairin most cases the repair will take just a couple of hours including the readjustments to convergencethe price will be good investment attempting to repairby yourself could render the TV chassis unrepairable
