The optical block is not easy to install. you literally have to remove almost everything to get to it. Also the shutting off is most likely the lamp assy and then possibly the ballast that drives the lamp. I reccommend an authorized sony repair center.

Sony tv has blue dots on the screen


Hello, the optical block is bad. Sony had a program on the issue, but it's expired. it would cost more to replace the optical block than to buy another set around $1100 to $1200 from Sony........thanks, Terry

Problem with blue dots on screen plus blue haze in lower left hand corner. Replaced lamp approximate 1month ago with Phillips lamp Assy. Blue dots started to appear about 1 week ago and are increasing in...


The optical block is most likely causing the problem. It will continue to get worse. Sony may help with the repair since they have had a lot of problems over the years with their optical blocks across many models. On the older sets they usually only help with the parts cost. The average repair cost for a optical block replacement is $1200.00 to $1500.00. So if they help with the parts cost it really brings the cost down. Their customer service number is 1800-222-SONY.
I hope this helps,

Blue dots in screen . does that mean the lamp is going ?


Hello

I dont know of a good way to tell people bad news. The problem with the blue dots is expensive. A part called the optical block is failing. In general, the optical block takes the red green and blue pictures from the little lcd screens and puts everything togther perfectly. This requires several mirrors, filters, lcds, and parts that I dont even know the names of.

Buying a brand new optical block is a 1000 to 3000 dollar thing. To have the block rebuilt is about 350 dollars.

Sony has been trying to make the customers who purchased these tv's happy by providing extended warrentys, or giving them a special deal on a similar sized new LCD tv.

I would try to complain to sony and see what you can get accomplished. If you do opt to repair the optical block the odds are that it will happen again in a few years. Ebay and the chicago craigs list are where I have seen the guys who are capable of rebuilding those blocks.

I am sorry for the bad news.

My sony t.v has blue dots and blue patches all over the t.v


It sounds like it has a defective Optical Block. It is a very common problem. Sony had extended the warranty on a lot of these models. I do not know if this model still qualifies. you can find out by calling 1800-222-SONY. Even if it is not, they have been a little liberal and may help with the parts cost. The Optical Block would normally run around 750.00 to 900.00 depending on model number.
It would be a major tear down to replace and I would recommend a authorised service facility to be involved to replace it. Sony could also help to find one for your area
I hope this helps,

Hi.. i have a sony kdf42we655. had to teplace the lamp in August and since have had blue streak on side of screen and now blue dots here and there. Did ck to make sure lamp in correctly and screw tight....


the problem is your optic block. you probably had this problem before but since the lamp was almost dead you didn't see it. There is a place in Indiana called Tri State Module that will repair the optic block for $299 plus shipping. They are the only place that repairs these optic blocks. The only other option is to buy a new optic block. which will be alot more than TSM charges to repair yours. the link to their website is www.tristatemodule.com

Blue dots and streaks


Blue streaks might have been just your video connection and problem with signaling. But, blue dots is faulty light engine, aka "optical block". The engine in this could be a defective LCD array. Very expensive, a optical block is about $850. Hope it's still under warranty. You could get a rebuilt one, possibly. Need service adjustment too. Bad problem that Sony has with these kinds of sets.

This model also has a paper filter for the Optic block that should be changed. No one ever said anything about it. shortens the life of the optic block if not changed.

BLUE HAZE


That could only be the optical block, Sony p/n# A1084662a and heaven help you if it needs to be replaced. It is the single most expensive part of the DLP based projection Tv's costing approximately $900.00 dollars plus core and shipping..
You'll need to take this one to a quality repair center to have it estimated. It may be that they can repair it also - but whatever the case these type of repairs are not cheap.
Please don't kill the messenger...
Good Luck!
