I have a blue spot on my LCD screen panasonic MODEL PT-52LCX35. I replaced the bulb unit and still have a small blue spot on screen
Hello bslobo.
The reason why the blue spot still remains is because the lamp only emits white light. The one in charge of giving color to the picture is the 3 LCD chips (red, blue & green).
There is a probability the one or two chips might have started to burn in some areas due to the heat emitted from the light passing though them.
In order to fix your problem is to replace the chips; however they are very difficult to find individually, they are normally sold with the entire light engine. If you still have your warranty I would recommend calling Panasonic.
If you have any more questions feel free to ask.
Good luck.
