RCA P52754AT	Can't Post

I have an RCA P52754AT 52" Projection Television. I have had the unit for 10 plus years without any service issues. I am currently having a problem with the blue seeming to be out of focus. If I go into the projection alignment the blue seems to over projecting. It is extremely larger that the other colors. Any help would be appreciated.

It's sound like the focus went way out of range or the ptv fluid leaked from the tube and ran down the side of the light box. The fluid leak is a common problem with that unit. The diapham dries out and the ptv fluid leaks out and normally causes other issues with no pix which leads to the leak. Remove the speaker grill and the access panel look for liquid spill inside. Get back with me.
