To clarify...the LSUQ0100 will correct the fuzzy spots, but it does not fix the blue dot issue..I just fixed mine with LSUQ0100..fuzzy color blobs are gone, but blue dots still there...oh well. :(

    to follow up on my own comment, I started to dis-assemble the tv to check for problems, and I noticed the bulb (which I replaced 2 years ago) had many little pit marks on the reflector. I will replace the bulb to see if this fixes the blue dot issue, and report back. Btw, the blue dots are different than the color blob, best way I can describe them is as tiny little blue "freckles" all over the screen

    This is the final follow up to this, and I apologize for not posting it sooner. To recap: Some of these TV's have a issue with the controller board that is connected to the 3 lcd screens inside the light engine. The issue is a programming issue that causes "color blobs" on the screen. This CAN be fixed with factory tool LSUQ0100. The tiny blue dots that were on my screen, ended up being the blue LCD was failing, and LSUQ0100 DOES NOT fix that. The only fix for that is to replace the blue LCD, which is quite difficult to find, and inside the very core of the light engine. Most TV repair shops wont even touch it. I ended up finding 52" version of this TV cheap because of external screen damage, I swapped that TV's LCD's, controller board, and prism over to mine. I had to re-use my output lens, as it was different than the 52" version. My TV now works perfectly. The truth is, unless you are willing to tear the tv completely apart, and lucky enough to find the right parts, you TV is junk once the tiny blue freckles start showing up. The blue LCD WILL eventually completely fail. Hopefully this helps some people.

I have blue dots on the screen. I cleaned the glass on the projection bulb and the prizm but still have blue dots.

Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team at 1-239-768-7547 and ask for the recall issue Sony had repaired free of cost for such issues previously. Hence, contact the customer relations.

KF-42WE610 blue dots and blue vertical haize

Go to the Sony Web support site. If your TV is one of the models listed with the blue dot problem (there are pictures of what the screen looks like with this problem)on the site, Sony is now saying that they will cover the cost of the part and the repair. We did what I'm suggesting and are having our part put in today. Sony decided this was their responsibility for some models of their LCD big screen HD TVs in June of this year. We were contemplating an estimated repair bill of over $1000 until we found out they were taking responsibility for this problem. Good luck, I'm not a truly techy person, but hope I have pointed you in the right direction. We have been living with blue people, etc. for about a year now, feeling angry about spending so much for a TV and it going bad so quickly. Hope this spares you that. You have only so much time to take advantage of this repair offer...
