Anyone who owns this TV and has tiny blue dots on their screen, we need to fight this. "Sony knew about the problem with their video blocks and even extended the warranty coverage for this problem for two years. That extended warranty expired on June 30, 2008. If the problem began to manifest itself one day after that you face a minimum of a $1500.00 repair."
I just finished submitting a file to the BBB (Better Business Bureau) via the internet. Please do the same! If we all get together, we will win what we are owed. Sony needs to take on responsibilty! Please submit file with the following name: Sony Service Center (Clearwater, FL) Houston, TX

This is a recurring problem with this model, along with the 50 and 60 inch models. The problem lies in the Optical block needing replacing. I've heard that Sony, depending on the serial number (or manuf. date), will cover the repair, in some cases, so I would certainly check an authorized Sony service center 1st. Good luck

You have something on the lens. If the lens was producing excessive heat it could be the melting around the lens itself, or it could be grease from your finger that was clear until it got hot enough to cook onto the glass. Either way, remove and clean the bulb lens (the one on the bulb you change out when the bulb blows) and then re-clean the focus lens on the front of the projector (the one you turn to focus).
If this doesn't clear it up, look for damage on the focus lens or the bulb lens.
I haven’t actually worked on this model, but I can tell you that the problem is NOT the lamp. You asked how you can tell when the lamp needs replacement, on the front there is a indictor labeled “lamp.” It will be flashing when the lamp does need replacement.
Being a LCD (quite like the LCD on your computer) over time you can develop bad Pixels. I am sorry I don’t have a fix for you, but I do hope you invested in the extended service plan on this one. Best of luck to you!
The discoloration you see is dirt that has been fused into the lenses. You should see a Blue or Green discoloration on the to or left hand side of your screen when they start causing a problem.
Please do not quote me on this, but it works!!!
If you own a Dremmel Tool, use the polishing attachment and the brown polishing compound. Now gently polish not only the part of the lens that has discolored, but the whole of the lens. You need to do this until you have removed all of the shiny covering the factory sprays on the lens. If you do not, you will have discoloration all over you screen due to the change in bright ness caused by the couting not being uniform on the lens.
Caution, make sure to check which side of the lens is top ans whether the rounded block are pointing to the lamp or away from it. This will also cause endless probelms if you do not ut it right back they way you got it!
Further more you have to do both of the polorizer lenses, not just the one that is dull! Remeber you are not trying to get the lenses shiny, it will never again be... just get them uniform in surface dullness.
I have done this several times on the 42" as well as the 50". I have not yet had this problm on the 60" - They only crack the Blue LCD panel.
Depending on when you bought this TV, this could be the lamp. Does the red light below the green light come on? (That's the lamp light). This light typically comes on around the 3rd year of use for an average individual. I've recently enountered the same problem and will try to replace the lamp myself. Apparently its very simple.
The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.
Sorry to have been the bearer of bad news. Good luck : )
Check the optical block repair at sony's warranty website...
Could be the problem they have been covering it under a recall of sorts. $1250 for the optical block and they are only doing it until the end of the year so don't waste any time
if the lines on your screen looks anything like the image below, you do have a problem with the lcd, problem is you need to replace what is called the light engin. unfortunatly the price of this part is just about as much as a new replacement tv. Get a sceond opinion fron a sony service center near you, as i cannot see your picute. good luck
