    The picture is still centered, but the colors don't line up. The top of the picture dips down and there are lines across it.

Look for bad stk's on convergence module. This may take care of pincushion too.

If the convergence amp board didnt solve your problem then you most likely have a bad convergence power board. The board to the left of the convergence amp board should be changed at this point. But if you know how to use a meter we can verify this by checking some voltages, or you can just order it and put it in. Let me know what you want to do!

This is usually due to a convergence problem. Due to its history, there may be some bad connections. Even in dry storage, it was probably subjected to temperature changes. Try resoldering the convergence ICs first. Update this with the results. In the meantime, I'll look into this particular model for other suspect areas



There is a problem with the tuner. The replacement cost of the tuner wouldn't be worth it. You can try looking for bad connections in that area or check the power supply to be sure the tuner is being fed correctly. At this point, I'd say spend the money on a new set.

A red blue and green line comes across both the top and bottom of my tv . alignment is also off


Sounds like the classic convergence option symptom. If you press menu and scroll to the set up screen see if the auto convergence feature is still listed. If its no longer there the rca repair kit called ITC222 and ITC222A convergence option missing repair kit from www.tvrepairworld.com will usually repair that problem. The kit contains the parts and the CD with repair instructions.

RCA d52w23 shows pictures in triplicate:blue green and red.


There are several things that can cause this. There is a "light pipe" that connects from the lamp to the color wheel. If the mirrors inside have become dirty, broken, or have shifted it will cause the picture to do this. Also the color wheel itslef could be dirty or worn out. And the final culprit could be the light engine itself. You can have any in home TV tech test these out for you.
