My issue is a little different: Pinkish/purpleish stripe, about 1.5 inches high, all the way across the top of the set....is this an optical engine problem?
post #3692 of 3890
There is 95% chance. The optical block contain everything, the LCDs, mirror, color filter.

Hey guys wondering if anyone can help me. I'm trying to clean the fans for my tv (70XBR), so as to keep it from overheating. From what I understand there is 3 of them. Is there any pictures or a manual telling me where they are or how to do it. If i'm opening it up I just want to be sure that I clean everything that needs it.
Thanks in advance.
Bill

Try this site for a general idea of how to remove the optical block assembly. http://sites.google.com/site/sonylcdrptvproblems/ The XBR is slightly different and a little harder to do. Make sure everything goes back in the way it came out. There is a set of plugs that can be crossed and you will ruin the board if you get it wrong. They are thin blue wires with red or black tape on them. The black one goes in the left side. I just did one of these yesterday. There are 3 fans. One is right as you open the set and easy to reach. The other two come out with the optical block assembly. You will have to have a 10" #2 phillips screwdriver to remove the assembly. One fan is on the top of the assembly and one is on the bottom. remove the fans and use compressed air to be sure you remove all dust clumps or some of it will end up on the lcd panels and discolor the picture.removing the fans for cleaning is good to keep the dust away from the lcd panels. Good luck.

I have a service manual for the KDF-60/70XBR950. If you are interested in it, you can send me a private message. Also, you can check out my web site on Sony optical block problems:

I am looking for these sets to repair. If anyone is getting rid of their Grand Wega, XBR or SXRD, please consider offering it to me before you dump it. I have had tons of luck rebuilding optical blocks, repairing them and really enjoy working on them. I am in Connecticut and can travel for pickup. Thanks, John

I own a 70" SONY (KDF70XBR950) and have notice lots of blue dots (stuck pixels) and blue haze on the right and bottom of my set.
The set is almost hard to watch now.
If this is the "optical Block" defect, shouldn't SONY pay for the repairs?
I am almost certain that I am out of warranty
How is it my fault that I was unaware of a defect?

What can I do - short of trashing the set?

Hey Splinke
Can you tell me where I can order a service manual for my Sony 70" set (KDF70XBR950).
I was able to locate an optical block from discount-merchant.com for $179.99.
They are out of stock right now.
I am thinking of replacing the device myself.
I am a EE and very handy - thus I think I can do this (fingers crossed)
My other option is to have a qualified tech do this for me if it does not cost me an arm and a leg (he he he)

Here a re my symptoms
large blue haze on the right-side and center bottom of the set
star patterns (2 of them) on the right and center.
ghosting image in the middle of the set.

After tuning to CNN, if I change channel, the CNN logo is etched on the screen for whille
the star patterns appeared about 2 months ago with 1 or 2 stuck blue pixels.
2 weeks later, I had about 20 to 30, a month later it grew to about 40 to 60.
now I have about 100 or more stuck blue pixels on the screen

PS
So far I don't think the fan door housing is damaged or warped - it looks fine.

Other options
JBJ220 - can you fix mine?
How much $ - am located in central New Jersey

ench,

Send me your email address, and I can hook you up with your service manual. You can do it by Private Message here, or by sending me an email to the address listed at the top of my web site.

The service manuals provide some information about taking apart your TV, but there are not really step-by-step instructions. You can get further guidance from my Optical Block Replacement/Cleaning page. If you are a handy EE, you should not have much problem. Just make sure you have a long-shafted Philips screwdriver and some patience--and make sure to document everything as you do it, so you can reverse the process later.

I doubt that Discount-Merchant will ever have your optical block in stock, as they are not a reputable firm based on current Better Business Bureau ratings. TriState Module is another option, but they typically just refurbish optical blocks that are sent in by customers. You could try calling them to find out. jjb220 may also be able to help you out, but I am not sure about the "star pattern" issue.

Splinke
I sent you an email as instructed, and thanks for the expedicious reply.

I already looked at the posted instruction, and believe I can replace my optical block.
I saw the step by step replacement/instrunction and that motivated me

Next step is to wait for discount-merchant.com to have the part in stock.
Wish me luck (I may need it )

I see now what you stated in the price of 179.00 was from Discount Merchant. They have been out of stock for over 2 years. I gave up on them in about March and started rebuilding them myself.
I am sure I can rebuild it but I would need the set. I dont have a test rig for the XBR yet and would have to do a rebuild by using your sets electronics for testing.

I managed to hook up a URL for the picture.



For the OB to be repaired, does it require me to bring my set to you?
Its kind of heavy and bulky.
Or are you implying I remove the OB and send it to you?

Yes, I didn't even notice that ench referred to Discount Merchant for the optical block. I thought he was referring to TriState Module. Be cautious about dealing with Discount Merchant, as they have an "F" rating from the Better Business Bureau (on a scale of "F" to "A+"). They prowl forums like this trying to sell their projection lamps by setting up multiple accounts, pretending to be other TV owners, and then recommending themselves. I find this unethical, and I have observed this behavior in multiple forums over several years. Perhaps they just added fake links to optical blocks in order to draw rear-projection customers to their web site to buy other products like the lamps. Who knows?

Can you open the back of the set and get the part # from the optical block? This will tell me if I need the set or if you can only ship the OB
post #3712 of 3890
splinke
Thanks for the heads up.
I thought the price was too low.
I was on their web site and the OB was not listed, and the rep said they were out of stock
I was chatting on-line with one of their rep who quoted me $179.99 but absolutely refused to give me a parts number.
A google search on the part number revealed several vendors (all out of stock) with prices ranging from 349 to over 1500 bucks

On another note, after I looked at the manual that you sent me, I am positive I can replace the OB myself.
Thanks

I am working on a test rig for this optical block. Ill get back to you as soon as I can so I can offer you a rebuild. Otherwise I need the tv to do the testing.
post #3715 of 3890
By the way, SONY has the OB on their site for about $518.39
https://servicesales.sel.sony.com/ec...oductSearch.do

I hate to make them profit those f#$%)@ bastards

Anyway, I just bought a can of compressed air from Home Depot.
The plan is to open up the unit and look inside, remove the OB and try to blow some compressed air through to remove dust etc.
This is a practice run to see if I can remove the OB, and put it back before shelling out 518 bucks.
post #3716 of 3890
OK
Here we go!
Back on the unit is open - wires, connectors, parts all over the place
I took pictures as I remove parts, etc.
Finally, some 3 hours later, the OB is out.
I fell like my TV just gave birth or I just delivered my first OB.
I followed the cleaning instructions from this link (as much as possibe) http://repairs.sunnyoasis.com/sonylcdtv/

But it seemed my unit was clean or looked very clean (to me)
- except for one fan that was real dirty, so I clean it.
I tried to clean as much as possible.
But the bottom line I think I need to replace the OB

Now comes the fun part
I will attempt to re-assemble it all back
wish me luck

Let me know how it goes with getting it back together. Im going to work on the test rig for the XBR950 and will get back to the forum to let you know if it worked.
post #3718 of 3890
I put it back together ok but
still have the same problem with the blue haze and the stuck blue pixels displaying as a star pattern (oh yuk)

But at least I know I can get it back together

JJB220:
How long will it take you to hook up your rig?
Should I wait for your or get a new one from SONY?
I am leaning towards putting up the big bucks and get one from SONY
Are theirs new ones or refurbished old ones?
post #3719 of 3890
I took the plunge and ordered my OB from SONY this morning.
This is a brand new unit (with same defects as the design probably have not changed)

2003 Model Year Grand WEGA™ Televisions

Models: KDF-60XBR950, KDF-70XBR950, KF-42WE610, KF-50WE610 and KF-60WE610

As technology evolves, Sony continually looks to stand behind the reliability of its televisions. It has come to our attention that a limited number of Grand Wega rear projection televisions (models listed above), after a period of time, exhibit blue dot or star pattern on the screen.

As part of our commitment to quality, Sony is announcing that for any owner of these model televisions who paid out-of pocket expenses on or before December 31, 2007 for an estimate or repair service to replace the optical block for this specific issue, Sony will reimburse the customer by mail for his/her parts and labor expenses. To receive reimbursement, please follow completely the directions on the claim form for reimbursement; all claims must be postmarked by June 30, 2008. See claim form for complete terms and conditions.

In addition, for any customer who later experiences this issue on one of the affected models, Sony will cover the cost of the optical block repair (parts and labor) at no charge through June 30, 2008. All other terms of the Sony limited warranty continue to apply. Sony utilizes a network of hundreds of qualified independent third-party servicers to perform in-home television warranty service. Sony, through its authorized servicer network, will endeavor to repair your set within 30 days of your first contact. For diagnosis, warranty service, or if you are not provided a repair within 30 days, please contact Sony at (888) 649-7669.

I wish I saw this original post ( post #3464) from SONY.
They are admitting the flaw in their design.
So how is it my fault that my set exibited signs of optical block failures after June 30 2008.
