Did this video help you?

Charlie Gaziano: Thank you so much!!! I have a DLP Projector that I've been trying to fix up for fun. I had replaced the blue LCD because of spotting. You're video helped explain the alignment process for the LCD and it's polariser! It was a lot of help!

Harry Hamilton: I checked with Tristate modules. They dont sell the polorizer filters for the blue lcd on my Sony Wega. Any idea who is selling them?? Cant find them ANYWHERE! Tristate doesnt even include one with the lcd panel anymore. They make you get the whole the rebuilt for $200 to $300. HELP!!!!

brian thomas: anyone know how u get the grid? 

Harry Hamilton: How do u get that grid picture on cieling to line things up? Wheres that grid pic come from?

Adam McNutt: I haven't taken my KDF-E60A20 apart yet, as the blue is starting to creep in, but I am unable to find a part # for the LCD and the polarizer. Is there another model this can interchange with? Also, am I understanding that the LCDs are just B&W, so I could use a "green" LCD in place of the blue so long as the polarizer is one for a blue LCD?

Alfredo Texaca: hey I have a KF-60WE610.. can that backplane on this model on TV be Updated with a newer Update unit. My unit does not have HDMI. I've noticed later units have HDMI, I was wondering, just how compatible some of these modules are between series. If its Modular, there could possibly some compatibility between chassis. #2, Why does the Picture get dim on this units? Is the problem in the Chassis? or some other module? BTW, the information you have shared with us is Incredible and Invaluable, thank you for sharing. If you have a PayPal account, I would have shot you a couple a bucks. ;-)

Grecia Gonzalez: I Have a SONY PROJECTION tv MODEL KF-42WE610. tHE FRONT LIGHT BLINK IN RED COLOR 8 TIMES THE STOP FOR 2 SECONDS AND DO IT AGAIN. I WANT TO FIGURE IT OUT WHAT IS THE PROBLEM. cAN YOU HELP ME PLEASE. Thanks a lot.

ThEiNsAnEiRwIn: I'm trying to fix a sony wega 70 inch. It has a bluish/green tint only noticeable on dark scenes or a black screen. Is this definitely the optical block? I found a guy who will fix it for 250$ but would rather do it myself. I just want to make sure this is the problem. Please help 

javier maldonado: Great video,,I own a KDF60XS955, it has perfectly green vertial lines i have seen them disapear ,but now it just stays there all the time ,,,,I'm planning on buying the whole optical block assambled,but it does not come with the polarize filters,,,this will solve my Problem????By the way the block is brand new, and needs no adjustment as they say.,,,THANKS WITH ANY INFO ANYONE CAN PROVIDE

Michele Napoli: If anyone get's a turn on and off every 30+ SECONDS after changing the the light bulb and still can't find the trouble shooting do this! (it's the female light bulb socket that is burned )go by the internal female light bulb socket unscrew it cut it off from plug and also cut off male plug light bulb and directly solder wires together (you can extend even the cables use same wire gage) make sure you tape/isolate very good the wires ...and the 30+ second turn off TV would be GONE ;) BTW nice video on explaining on all details !!!

Harry Hamilton: I'll give it a shot. I found a donor tv with the same exact problem. Gonna try to use its red lcd panel and mating polarizer filter as well, to replace my bad blue one. Thanx for ur help.

Jim Domino: This is what is wrong with my TV, it is the KDF55WF655, based upon what you stated above, this can not be replaced, or do I need one of the following parts LCX043ANB4 448089P GR LCX043APB2 448106P RL LCX043ATB2 449118P RR LCX043AUB4 449141P G

Mike Seybert: I have a 55in Sony with those same blue dots and I was gonna watch this video and try to fix it myself. I was able to find a new LCD panel but I can't a polarizer anywhere. Can u help??

Miguel Angel De Abreu Da Silva: Hello good day! my Sony kdf-46E2000 works well! the only problem I have is that the picture looks yellow and green! that this failure is due and uses a lamp xl-2400

Yo p: I am from Ecuador and I have a KDF-E42A10 and my tv was working fine until that a day the screen started be green after red, I changed the lamp, and It was fine some days, but after started again be green, red and now only be red. Please do You know wich is the problem. Thank you and God Bless you. Att. GVM

kevtr6: I have a kdf e50a10 with blue spots in a star pattern in the center. I am not finding any options online for replacing the optical block. Any ideas? Colors are great behind the opaque blue spots. Would a breakdown and cleaning help?

MaGorSeven: Hello, Just installed the LCD panel on my Sony vpl hs50 projector but the blue seems to be out of allignment... Can you tell me how an allignment is performed here? because the projector will not turn on when it's not fully assembeld due to protection circuits not being "closed'. So i can't perform an allignment like some tutorials I've seen on Sony rear projection TVs where they do it when the TV's working while half disassembeld.. tnx E.S.

Draxx0n: First off, thank you very much for making this video! I have to ask though. After days of searching for the optical lens (I have the blue dots) I have not found it anywhere. Please PLEASE tell me where I can find this part. Thank you for your time.

sean somerville sr: hi i have the problem in your video. my next problem is i was given TV by someone who had it replaced and the model number tag has been torn off? i need to know what i can do its 50" with speakers built in sides gray in color and says sony wega? i want to get the parts but need to get correct ones can you help.THANKS SEAN

13mgreg: @norcal715 Thank you for the great video on the Blue fog repair but after fixing the issue Green Lines randomly came up on screen and are spread evenly through out. What is the issue?

sean somerville sr: sorry also see other people asking about polarizer to match optical block? thanks again Sean.

MaGorSeven: Hi norcal715 Just installed the LCD panel on my Sony projector but the blue seems to be out of allignment... Can you tell me how an allignment is performed here? because the projector will not turn on when it's not fully assembeld due to protection circuits not being "closed'. So i can't perform an allignment like some tutorials I've seen on Sony rear projection TVs where they do it when the TV's working while half disassembeld.. tnx E.S.

Rocko: What would cause an slight opaque red bar about 1" thick and the full width of the screen at the top of the screen on a Sony KDF-50E2000? Thanks.

norcal715: the dark could be just a old lamp, get a new Philips lamp and see if the brightness improves. the blobs are most likely dust on the LCD panels themselves. all you need to do is remove the LCD assembly and with a very fine paintbrush and compressed air brush the inner and outer surfaces of the complete LCD assembly and blow off the loose dust and that should correct it.

norcal715: On the power supply look for an IC "MCZ3001D" if you see it try heating it up and see if the set starts. I have had a couple of them that were bad.

norcal715: Nope, the LCD panels are the same in all of the sets. So they are interchangeable.

Paul Beyer: One thing I would like to warn everyone who watches this video about is that some of the Sony TV's have the polarizer positions different than in the video. Make sure that when replacing the Blue Polarizer Units, you confirm the position on the optical lamp unit. I didn't and then had to correct for 2 out of position polarizes which makes the process much harder and longer to solve. This is not as easy to fix as the video makes you think, but you can do it. Very thankful for the knowledge now.

Neurocidal: Thank you so much for all of your videos, extremely helpful and educational. If I may ask a question to this particular video? How are you creating the colored grid for the lcd alignment step and what is the image for aligning the polarizer screeen? I will be attempting this repair to this TV soon and would like to use the same grid image to adjust the picture. The technique seems to be perfect. Thank you , keep pumping out the great videos!

bkwolfe88: Thanks for posting this. The instructions were simple and only thing that gave me trouble was the alignment, that took me a few tries. now the picture on my tv looks great.

norcal715: The UV light is what kills the polarizers and LCD. use compressed air and a fine artists paint brush to clean them. the 2 blocks are most likely just a little bit different but they may work. its worth a try.

norcal715: lcd panels may not be connected in the 3 connectors correctly or engine power or LVDS cable damage

Kevin C: Note: depending on unit age, there are several different part model numbers for the LCD screens. Some common part numbers for this are listed below, but its not a complete list. Be careful as some models will use a very similar looking part that will not work in this model-set television.

MAXKC1: just pulled out a light engine last night, from a KDF-55XS955 sitting on the curb. I have a KDF-50WE655 that needed this fix. ready for the challenge. great vid Just two questions, dust and heat are the killers of these polarizer, and lcd's? and also, any recommendation on cleaning these out, say every six months, year?

davishous1: you dont have to do all this you can remove the front panel and the lamp housing is in the front

norcal715: You can hook a computer up and run my 1080 HD test pattern from you tube. As far as why the LCD breaks down I have two theories. #1 not enough cooling. #2 too much UV unfiltered and damaging the panel and bleaching the polarizer. I believe that the darker polarizers will block more of the UV light that the orange(blue) polarizer that lets more of the UV pass. We will have to wait 5 to 7 years to find out.

Don: Okay I got everything running, but when I turned my TV on, I saw a lot of blue lines all over my screen, and I'm guessing something went wrong, I used the Crosshatch pattern video you posted. But when I was adjusting I couldn't see anything misaligned ... What do you think I could be doing wrong,

Kevin C: This is to replace the light engine lcd panels, not just the bulb. The front access panel will not allow engine removal as its done top-down.

rvcasrfr: You are a GOOD F'ING MAN. I just replaced my bulb and along with the blue splothces my KF42WE610 also has a yellow tint across the entire screen. Any idea what this is?

norcal715: most likely different optical blocks but the LCD panels are the same, you may be able to change the entire LCD block from one to the other.

MrViktorX: I have the same television that is in your video and I noticed that you used a grid pattern to get the lcd panels to line up. I have done everything else and this is the only thing that is left for me to do. I have my television sitting in the living room in pieces until I can get this finished. My wife is complaining about the mess. Please help!

Hssan Kadisi: hi there im trying to buy the lcd panel but how do i know if it blue or green , people selling as work for sony !!!

maurice hughes: Hi i was curious did you replace the whole blue polarizer frame you took out or just the see through filter

Paul Schroeder: My old LCD panel shows a blue haze around a regularly colored circle. I see black through that circle (as expected). When I drop the new panel in, there is no black (the expected screen color), only blue. The new polarizer shows no discoloration on an LCD screen, so I'm assuming that it's the panel with the issue. The old panel was labeled BR on the cable, the new one has RL on it. I hate to bother you, but it's extremely frustrating.

Luis A. Montana: HI, GUYS I HAVE THE SAME PROBLEMS BUT MY TV IS SONY WEGA ENGINE 3LCD E50A10, I DO NOT IS THE SAME PROCESS THANKS !!! FOR SHOWING

norcal715: 6 blinks on these usually means a thermal sensor is disconnected. There is a little lamp thermal sensor that sits near the lamp and as I recall is a 2 pin cable with a black connector grey and white wires I think. plugs in near the lamp fan on the top rear of the light engine.

SilentJackal75: What did you do to keep the TV on? Since I have everything out of the tv, it turns off after 2 seconds because of the lamp door switch. What am I missing here? TV is a model KDF55WF655.
