Black spot in the middle of the screen looks like it has a burned spot


Yes if it uses 3 picture tubes one is burnt dead center--cover the lens one at a time to see which is causing this--permanent damage caused by a arc.

If a newer set you have a display unit with a dead pixel.

Having a big yellow spot background in the middle of the picture.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

DARKE SPOT IN THE MIDDLE OF THE TV. Looks like a shadow. You can see it really good on light blue and with colors.


Sounds like a burnt blue CRT phosphor.-- Can't reproduce blue at that spot. It would need a new CRT.

Hitatchi 52" rear projection TV has blue spot in middle of screen


Hello :
I suggest u retrace you the steps u took to replace your lamp make sure no foriegn objects got on the prism where the light shines throung the optics engine, if you remove the lamp compartment througly. If you had a perfect picture prior to replacing the lamp, then retracing your steps you might find something that does not belone. One final note: Did you purchase the right lamp 120watts anything higher than this wattage could damage your optics engine. I suggest never vacuuming the compartment because particals fly around from the suction and could get on the glass of the color wheel asembly.

Rca D52W20 blue screen when turned on


Almost certainly the blue picture tube is bad. This is a huge job to replace and quite expensive. Generally it is not worth doing.
