You have a optical block issue. Contact Sony support to see if they are still honoring the extended warranty. This can be done from the web or by phone. It's likely you will need to speak to them if the extended warranty has expired. NOTE - this is not your warranty, but a Sony accomodation for a early production issue.

    These issues are problems in the light engine (optics block)the dots are called "starfield" and the geometric is "roadmap"
    replacing the light engine will fix the issue. for awhile, sony was extending the warrany on the engine for these issues only, but that may have expired.

Problem could be internally on the main board.either bad ic or capacititor or bad soldering at junctions.needs to be checked with a multimeter to locate the exact faulty component.

Little blue dots on screen and large blue haze in upper left corn


Sounds like the light engine is going bad...that's why they stopped making these rear projection sets using LCD's. Costs almost as much as a new set! But get a second opinion before trashing it.

Blue dots and blue area on my screen


Your blue LCD panel is failing. It is within the Optical Block and the entire block must be replaced in order to repair this. Over time (usually a short amount of time) this problem while progress until the picture is bad enough that you will want it fix immediately. So, it's good that you are looking into this now :) Here is a PN for the Optical Block... PN: A-1084-668-A I hope this helps.

Blue section (corner) and blue dots


This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

Blue section (corner) and blue dots


Hey there Aleman500-

I had this exact same issue with mine. Started noticing the "blue cloud" on the bottom portion of the screen.

Please follow this link and the instructions listed. I opted for an "upgrade" that was offered (brand new 46" bravia lcd) but sony had also offered to fix my tv for free.
