Question about RCA P52960 52" Rear Projection Television

2 Answers

Red, blue and green vertical lines in middle of screen all functions are ok

Hi I have a RCA 52" / p52960. it is about 3 years. I had about six power flickers (on,off,on,off,on...off,on,off....on) one day, the tv was pluged into a surge protector that I got at the same time as the tv,later that evening the screen wnt to three, red, blue and green vertical lines, side to side, all other functions appear to be normal. sound is fine you can turnchanels and hear them change. it seems you can see the line colors jump as though the picture is active. I have looked at the tubs and they are all three have amber light at yolk when on.

Colors are seperated


This is an ITC222 chassis. Very common for broken pins under flyback to cause this. Resolder flyback and replace adjacent 400ma fuse. It's a little red box, there are 3 in a row and the one that blows is the middle one. If this does not repair, suspect the convergence power supply. It's the vertical board above the power supply. I've replaced the power mosfet on that a few times as well. And remember if there's any doubt contact a professional. Goodluck.

Intermitten snowy picture


well the vertical deflection IC is good but you need to get the conversion chip for it , it controls the vertical , horizontal, color, color alignment ,
it would be wise to get it done soon before anymore dammage is done
