Sounds like you have some bad solder joints. The problem is not fixing them but finding them. If you can solder and know TV safety you should be able to repair this. Unplug the unit and remove the back. The bad solder joints could be anywhere. Remove each board and look at it with magnification to identify the bad joints and resolder anything which looks suspicious. You could also resolder all the connections on the power supply board and see if that solves your problem. From your description of the problem it sounds like that is where the problem is located. Good luck.

I do wish sgregg would stop giving advice on things he obviously knows nothing about. The 65XWX20B is a standard projection set and does not have a lamp in it. It has 3 separate picture tubes. The power board is not the problem either because you would get no picture if it failed. You most likely have a convergence IC which is on the verge of failing and is starting out OK but acting up when it starts heating up inside. A good tech will replace both STK392-110 IC's with the newer updated STK392-150's, realign the convergence circuits and be done in about an hour and a half. When I do a housecall for a set like that I charge $150, but techs in your area will vary so ask around.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.
The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.
They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.
