Question about Mitsubishi WD-52525 52" Rear Projection HDTV
On this mitsubishi 40" vs-430ca projection tv I have changed the convergence chips and had no change there is no convergence adjustment function happening with the alignment buttons .trying to set the convergence has no effect. there is still a picture and sound but the picture has the top /bottom coloured bows I have not changed any resistors in the convergence circuit because I have no clue which resistors go bad . On my 60" zenith I fixed it with an r 3243 resistor on the smps module . could a person in the know about which resistors (and their values) go south in a mitsubishi set please let me know the rundown list and the approx placement in the set.
There are black in color circuit protectors in the set that have blown because of the bad convergence IC's. You will need to measure the voltages on the ICs and make sure you have the correct plus and minus voltages. There should be about + and - 24 volts on each IC. I'm afraid the only way you will know what voltage are what and where they should be would be to get a service manual. i am sorry i do not have this model to share with you. Good Luck.
