Panasonic PT52LCX16

Post by mbuna » Mon Aug 29, 2011 9:09 pm

I just picked up one of these off of CL for super cheap because it's really REALLY dim. Previous owner bought a new lamp from Buy.com, the one they list seems to be correct, but it's still very dim. I reset the lamp timer with no change. I took the rear assembly apart, it was caked with a ton of clay dust we get in my region. Cleaned it all out really well and reassembled it, but it's still dim, and is also showing yellow discoloration on the left side, and magenta on the top right. So I bought this on ebay:

I'm betting it'll take care of the discoloration. What remains is figuring out why the picture is still so dim with a new lamp. I think I'm reading ballast is the next thing to replace, but I'm not understanding which piece is the ballast I don't think. Is it the board that the power cord comes into? Is it also called a power board? If I'm unable to find a replacement ballast, would it be beneficial to try replacing capacitors on the existing one?

Thanks!

The lamp is accessed from the front by removing the whole front panel with the Panasonic logo (it snaps in and out), and just left of center is a small panel with a grey knob. Twist that to open it, then reach in and twist the knob on the lamp cartridge (make sure you let the lamp cool first o/c), and pull it out. When putting the new one in make sure it's seating all the way in there or you can make more trouble for yourself I've heard.
