If it is rear projection set, you may have a burnt tube; what happens in some models is a arcing may occur and it burns a spot in the center of the tube.

In this type of set there are 3 picture tubes (what is model number?) The way in this case to confirm this is remove the back and with the set turned on (BE CAREFUL!) YOU cover the three large lenses with a cloth one at a time----if one of the tubes is burnt when you cover that lens the spot in the center of the screen will not be seen.

If this damage is there it is permanent---the tube would have to be replaced AND WHATEVER ARCED WOULD HAVE TO BE FOUND AND CORRECTED.

LET ME KNOW IF I CAN HELP---I am here to help.

I own a Sony KDF E50A10 3LCD TV that has developed a purpleish defect in the lower, center portion of the screen. Do you have any ideas on how to fix this?


It is an Optical Block Problem, Sony has settled several Class Action Lawsuits covering many models from 2002-2010. Start with this Link, it will provide you a very good starting point. Hope this helps

Spot in center of screen, if the color pictureis black the spot is blue, if the picture is white the spot is yellow.


Spots in screen is commonly caused by defective LCD on the optical assembly. LCD replacement is very difficult. I suggest to contact the nearest service center at your area.

Poor picture no color


OUCH! LARGE DARK SPOT IN CENTER IS NOT GOOD FOR PROJECTION TV. YOU BURNT THE TUBES. THE LOSS OF COLOR IS THE ROOT CAUSE SOUNDS LIKE A DEFLECTION CIRCUIT PROBLEM. THE TIMING FEEDBACK IS USED TO SYNC THE COLOR CIRCUIT. IF THE TUBES LIGHT WITHOUT DEFLECTION THEY BURN THE CENTER PHOSPHOR COATING INSIDE.

Large yellow spot in center of tv screen


Sorry, but there is no cheap method of repair for this unless it is in warranty.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.

Good luck.....
