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.....

My tv has black splotches or pools on the bottom


If the splotches are a shawdowy black and look like mold growing between the Lens, its most likely dirt or water spots on the bottom of the large mirror. I cleaned mine and missed a few water spots on the bottom of the large mirror and the splotches (spots) showed on the screen. Other than Dirt, or water spots, There is nothing else that I can think of that would cause this. Unless the Someone has cleaned the screen and it soaked up between the lenes. But it Takes about 30 minutes to disassemnble, give it a good cleaning and put it back together.

Yellow spot in middle of screen (sony-large screen-hd)


Sounds like the optical block (the projector part of TV is failing) The block cannot be repaired it has to be replaced. It can easily cost several hundred dollars to fix. Sony did extend the warranty on some models, you can try going on their website to see if your model is covered or not. good luck!

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.

It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

Sony 60" LCD projection TV has yellow screen discoloration


I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.

Yellow spot in center of screen


I have recently developed the same yellow spot problem on my Sony KDF-E50A10  50" LCD television...a large yellow circular hue that takes up the bottom center of the picture and is especially noticeable against a white background.  It has been diagnosed as the optical block (light engine) and without an extended warranty Sony refuses to assist with the repair cost.  Repair was estimated at $1,100 plus tax and travel fees to my home.  So you see, it is not only a Hitachi problem.  You would think they could build something that would last more than two years considering the initial cost of over two grand for the TV !
