Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
There is three coloured lines appers on the screen when turning on
but no pictures apperes.
If there is no picture and 3 vertical lines in the center of the screen, stop. Turn off TV. You have no horizontal deflection happening. Lines will burn into crts and be permanently visible after repair.
No horizontal deflection is caused by Horizontal sweep circuit failure, maybe flyback transformer and associated components. More than a simple do-it-yourself repair.
