Red convergence problem - Mitsubishi 65


It sounds like your red gun might be close to going, we had the same problem our tv. The red was off and couldnt really be adjusted but the others were alright. We were told that the red gun was nearing the end of its life and it could cost upwards of $1000 to fix, so we just got a new tv. i would suggest having a tv tech come out and look just to make sure, but thats wut it sounds like.

Mixing of these colour we can get the original colour chrominace technique. if any of the colour gun is faulty we would get more REad or blue or green picture. Measure RGB voltages. you can verfify which gun is faulty. if then check RGB processing circuits. Else there might be problem Chrominance colour decoder system. Contact service centre
