Question about Panasonic PT-47WX53 47" Rear Projection HDTV
"I have a panasonic 53" hd projection tv pt-53wx42
I have a panasonic 53" hd projection tv it hads blue lines on scree.
Blue background lines with colors otherwise OK may be a loose or dirty blur drive potentiometer on small circuit board behind front grille and beneath front imerboard cover. These are hot-glued in place from factory but may be the cause f the problem. They're VERY sensitive.
If you have bowed blue lines instead of properly aligned colors, you probably have a blown convergence amplifier IC. These boards are no longer available so yours will have to be repaired. Some shops repair them but many send them out for 6-10 weeks. Fairly expensive too considering the amplifier chips are about $35 each (x2).
