Hi I have a Mitsubishi VS-45VA2CA projection t.v.
It has lines going across the screen and the picture is green.I had replaced two ICS about 4 years ago the code on the back of these chips where 391020chc4 and 391020cba8 I don't know what these are I had a repair guy replace them it cost me 303.84 picture was great up until yesterday.could this be the problem again. any help would be great thanks
If the picture looks like a 3-D image, yes the IC's are most likely bad again. If the picture just has thin green lines or white lines in the green picture, then no the IC's are not bad again. There is probably a fault in the green picture tube drive circuit. it could be a bad driver transistor, a resistor gone bad on the drive board, or possibly the picture tube itself is bad. Depending on how well you like the set, and how much you will have to pay for this repair will be your guide on if you should repair it or not. Good Luck, and let us know how you make out on this TV set repair and if you had it repaired and what was wrong.
