So where is the optic block and how do i get o9ne/replace one?

Depending on model number of set you can check You Tube for video instructions and or several other sites also have this for free.

GOOGLE the exact model number with something like Optical block replacement of ......

No. If the set turns on and you have a picture, the lamp is installed properly. Most of the time the optical block is the issue. The lamp shines directly into it. If the picture was good before the lamp was replaced, it is possible that that replacing the lamp might have dislodged some micro dust build up internal to the optical block and it landed in a concentrated area causing the red and green lcd panels not to pass light through as bright as the blue giving you a blue spot. Unfortunately the optical blocks are not designed to be taken apart to clean. Replacing the optical blocks are expensive. Most costing in the area of $700.00 to $1200.00 for the part. It also is a major tear down to get to the optical block to replace it. Once upon a time Hitachi had a couple of recalls on their optical blocks for various models. I do not know however if this qualified.

Then you need to change optical block assy.Replaced with same which is menstion on optical block assy.like KHM...

Your problem is the optical block failing. This is very common with the AE700s. It actually happened to me once before and I had it fixed. After having it replaced, it was recommended I run my fan on high mode, run the lamp on low mode and change the back lit color to black from blue to help thwart the issue. The optical block fails due to heat stress from the projector. Doing the things above lower the heat and extend the life of the block. I have a perfeclty good optical block if you would be interested as buying them new are extrememly expensive.

Disconnecting wiring from power supply block

This step may be optional, if power supply block must be transferred to purchased replacement optical block. Undo the blue plastic-coated wire holders to release the two wire bundles. Disconnect the connectors shown with the dotted lines in the photo below. One, which presumably provides power, is disconnected directly from the power supply block, and the other is a regular wire connector.
Disconnecting the optical block fan wires

Disconnect the optical block fan wire connector:


Disconnecting the wiring from the optical block circuit board (C Board)

Carefully pull up on the three wire connectors directly connected to the top of the C Board:


Final wire disconnection from C Board

Remove the screw and gently pull the blue ribbon ribbon cable out of the side of the C Board:


Your optical block should now be entirely free of the TV and ready to ship. I recommend adding specific protection for the projection lens, then sealing the whole unit in a bag to prevent infiltration of dust or packing materials, then carefully packaging it with substantial padding.

Removing the projection lamp (in cases where you are installing a purchased replacement optical block)

Loosen the hex screw next to the projection lamp housing, and pull the lamp and housing outward from the metal clips.

Here is a picture of a replacement optical block for the KF-60WE610. Note that some parts of the old optical block need to be removed and installed on the replacement block.

This is an inherent issue with the optical block of your TV. It was an design flaw in the TV that is only fixed by replacing the optical block. This is the most expensive part in the TV and is very hard to replace.

Sony did extend the warranties for the optical blocks of this model until Dec 31, 2008. Try calling Sony to see if they will pay for at least part of the repair. You will need a technician to come out either way to replace the part as you need to take the whole TV apart to get access to it.

Hello,

You have the classic "blue blobs," In most of Sony's rear projection LCD's, the Optical block is bad. Manufacturer's defect. The blue panel inside of the optical block starts de-laminating (due to heat from the lamp). This is a very common problem. I have changed about 70-80 optical blocks myself over the course of about 4 years.

There is no other fix but to replace the optical block. Unfortunately, it will get worse, and will probably develop "stars," or stuck pixels, as well. You can call Sony and try to get some assistance, but the extended warranty on these sets has recently expired.

Hope this helps you in some way...

Hey joseph, actually replacing the optical Block is not necessary at all, all you need to do is get into the "Service Mode" of the Tv and change a few setting around, did it a few weeks ago and now my TV looks perfect, no reason to waster $1200 as sony is trying to get over on all us consumers.

I would suggest getting another optical block from the repair man. Apparently even some replacement blocks have had issues...

heat and dust are two major problems with this type of set.These set can get very dusty inside the optics and cause this type of discoloration .Heat can cause deteriation on optics and or optics cabinet parts .It is possible to clean the optics block for dust issues only but unless you know what your doing and know what areas not to touch inside optics block .Otherwise the block would have to be replaced..
