Blue spots on Sony WEGA KDF60XS955

Thats caused by a bad optical block. The cost of that repair will almost always be greater than replacing the TV.Thats a very common issue with alot of Sony DLP models which suffered that optical block issue with the blobs of color usually blue or green

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.

Please adjust TINT control of Video Settings in Menu that will adjust color tone of TV. I do not think this problem is related with Lamp because TV screen does not have any color blobs or spots.
Above solution is for Sony KDF-55WF655 model TV, if your model number is different, let me know.

Pink bar across top of tv screen

This could be from 2 things. 1 is the optical block is going bad or 2 you got a peice of dust blown in from the cooling fan and its blocking the color filter internally. If you are capable you can take the tv apart and blow compressed air into the color block and remove the dust. Hope this helps

Yellow spot in lower right hand corner

You have pretty much narrowed it down to being a bad optical block. This isn;t good news, since the optical block is probably the most expensive part in the set. Your best bet is to contact Sony customer support to see if the will allow some kind of accommodation for the repairs. Sorry for the bad new; hope it doesn't effect the rating you give me for the solution. Thanks!

Sony 42" grand wega LCD

We Cleaned the optic block as was instructed by another post. But now we have a wide ribbon of light yellowish to the right of our screen. Could it be more dust to be removed or now we can see there is more problems then we thought? Over all the screen looks much better. But a far cry from when it was new.

I just vacuumed out my 42 wega and it looks 100% better. Not for the faint of heart but it was free and only took me 2 hours.
