Hi, your vertical section is beginning to fail, from your description you have a few electrolytic capacitors that are beginning to go bad, the correct term is they are "leaky", the set can be fixed easily by a tech, not so easy for a layperson because you don`t have the service manual or a capacitor analyzer. NOT an expensive fix, tech will have to remove board, unsolder some caps, check them and replace the bad ones, do a little touch up solder work and set is good as new, any questions? feel free to ask away, if not Happy Holidays, BMW Rider

Please consult a professional for adjustment on these items as they are all near or connect to parts that have Hazardous Voltage.

52" RCA Rear Projection P52937SG Color Dots?


There could be an obstruction in the way of the three picture tubes on the inside. This tv has a chassis that comes out from the back all in a chip core frame with handles. Takes a quarter inch nut driver to remove and you should look to see if the speaker wires or the keyboard wires are obstructing the picture tubes. Other something I think of is a broken reflector and when you get the chassis out you can look up inside behind the screen to check for this and for any other obstructions.
