Optic block whats a optic block,whats there function,an how much does it cost?

Thats caused by a bad optical block. The cost of that repair will almost always be greater than replacing the TV.Thats a very common issue with alot of Sony DLP models which suffered that optical block issue with the blobs of color usually blue or green

You cannot. The blue blotch is a sign that your optical block is going out. This will only get worse. The optical block will need to be replaced. This is not cost effective.

You are correct in thinking optical block, but here is the good news. For the cost of a service call a tech can come out with a jig and reprogram your optical block and the problem should go away. It may be worth the cost to fix. Unlike throwing away a 900 dollar optical block.

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.

This is an incation of optical block gone bad and it cost to me around $1200 and with shipping and labor the cost of repairs goes past 1600.

However, Call sony customer care to confirm the cost of optical block before you decide. Check out for more solutions and price quotes at www.fixurtvs.com.

The Optical Block is where the Video and Light from the Lamp is processed then projected to the screen. It is one of the most expensive parts of the set. It cost probably 800.00 to 900.00 maybe more by it's self. You will not be able to find it on line because Mitsubishi keeps a very tight hand on them. Why did he con-dim the Optical Block? I would call Mitsubishi and see if they could help with the repair cost. Their phone number is 1800-332-2119.
