The only way to be sure is to have a tech evaluate it for a bad optical block

Pink splotches on white screen

I had a very similar problem with mine... You are correct, it is the optic block.. it will cost about a $1000 or so to fix. I chose to fix my 60" because I absolutely love these TVs. The Technology may be older but they are still great!!!!! (i.e. Instant refresh rate required!!!)

If you think you also have a dust issue just get a vacuum cleaner and clean the vents on the back of your TV. You can also remove the Front Panel... take out the lamp (make sure your TV is COLD!!! me on this) and vacuum what you can making sure you do not touch the back mirrors (located where your lamp goes in). You should do this every time you change the lamp at a minimum.

Pink splotches all over the screen.

You may want to call sony customer service,this is a known problem and they had a warranty extension on the light engines of many models of LCD projection. A sony Auth service may guide you to a free repair if still covered!!

I have a sony kdfe50a10 and the screen has been invaded by blue splotches. What's up?

The Light engine (also known as an optical block) which is essentially the projector part of your TV is failing and needs to be replaced. Sony has extended the warranty on some of its models so you can contact Sony to see if yours is still covered. If not it is outrageously expensive to fix easily over $1000.

No blue colors projected on screen

Only a few causes for this problem. "Splotches" are usually caused by dust in the light engine which can sometimes be blown out using compressed air. Pink picture is caused by either data or burnt lcd card. Procedure for data is: put tv to ch. 3 and turn power off. simultaneously press input and power on set for three seconds to access service menu. Be very careful not to change settings other than what needs changed. These adjustments are changed using directional arrows. Navigate to "memory init" then hold (r) arrow button for 5 seconds. You will know if it worked. Then exit and/or turn set off. Please let me know if this is successful as I have additional info you may need. Good luck, Russmann.

Different colors on the scanner screen

I didn't find a fix. I went to Best Buy and they said it would cost more than it was worth to fix. So I bought a new one. Thanks, mittenshadow

Light green and pink spots on my hd tv!!!

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.
