Had optical block replaced today - now it's a little magenta
I lived with the "green" discoloration for a while until I got the optical block replaced today. The picture is much better now but skin tones seem somewhat magenta. Is it because the optical block needs to be broken-in or is it just because the "greenish" hue was operational for so long? Is there a way to calibrate the monitor?

Your TV is an LCD rear projection type which requires a Mercury Vapor lamp. Mercury Vapor lamps emit UV light which is damaging to many materials. The discoloration you are seeing on the screen is the UV damage that has resulted over time to the LCD panels within the “Optical Block” (aka projector) of the TV. This discoloration has been creeping up on you for sometime, it just wasn’t as noticeable until you changed the lamp. Once you installed the new lamp, the UV light is bad at full force and the damage progresses at a quicker pace, due to the already weakened state of the LCD panels. Additionally, the picture is now brighter, exposing the damage for you to clearly see. The only fix for this problem is to replaced the Optical Block… an expensive repair. Although this is not good news, I hope this helps you understand the cause & solution and was of some assistance.
Hi,it seems you are experimenting a light engine problem.This is how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo So basically the 3 Lcd chips that create the colors and image is going bad and thats why you get that color discoloration.Contact Panasonic or look for your light engine online.God bless you and your house!
A discolored Blob or blotchy pattern usually in the center of the screen. the problem is becoming all too common with Hitachiprojection sets. What happens is that one of the lenses in the optical block (or light engine) starts to burn (in thi scase the blue one) or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far-gone except to replace the light engine-at a cost that makes it not worth repair. if the damage is minimal than to reduce further damage, the air filter should be replaced. The Light engine needs to be removed in order to replace the air filter. Be sure to vote/rate me if this helped Thanks!
Hi if your tv is a Dlp or Lcd it will be a problem with the light engine.Basically there's 3 chips green,blue,red that create the image and colors.When they start to go bad or melt you will get color discoloration on corners on the center.You will need to replace the optical block ,you can find it on www.discount-merchant.com www.shopjimmy.com or ebay .Have a blessed day!
Although Sony calls it the Optical Block, your problem is the light engine. If you don't have an extended warranty or it's not covered by recall, be prepared for the part's sticker shock. I had an RCA DLP which the company bought back from me after replacing three light engines -- I bought a Sony next. Experienced in the matter, one day I saw green blobs that quickly went away but I called my dealer immediately. They ordered the part and Sony replaced the light engine on my KDS60a2020 under warranty. I watched the technician make the repair and was amazed that he almost completely dismantled the TV in my home, so, it is best to get a Sony tech. (Or purchase a new TV, given the cost of the part and service call.)
If the set is hooked up using Component cables (red, green, blue), then check to make sure the cables are hooked up correctly, and not defective (change them out). If the color problem remains, then the problem may be in the Optics block of the television (which is not unheard of in this unit).
If the menu of the TV displays blotchy discoloration, and the discoloring is the same for every input on the tv (stationary), then it is the Optics, and the optics need to be changed. It is not the easiest job in the world, and the block itself is quite expensive, although the unit my be under an extended warranty from Sony. Contact them directly to see if you can get any help (cost or service-wise). Hope this helps...
You have a bad optical block. Sony is covering the optical block replacement under warranty, so you will not have to pay anything for the repair. Contact Sony customer service at 800-222-7669 to arrange to have your set serviced.
If they are pink or blue stripes, I have seen this before. I hope the TV is less than two years old, because the optical block has to be replaced. The optical block has a two year warranty on the part, but you will have to pay labor. Just to double check, make sure you can see it on all inputs and also that it shows up on the menu and on screen display. If yes to all of these, it's the optical block and no adjustments will help. Be sure to rate this solution. Thanks!
in some cases , the optical block can be blown
out with air. It must be remove to do so.
if air dos not work , then the optical block will have to be replaced.
I have had lots of luck blowning out the dust from the optical block with a air tank , cans of air dont have enough force
I have replaced alot of these light engines for this problem.
Yesterday I received a letter from Sony saying they are going to give an additional warranty to have the optics replaced.
I just checked, your model is one of them and Sony is replacing the optic block under an extended warranty, regardless of the purchase date, until the end of October 2008.
Contact Sony for an Authorized Service Center in your area or go to this site to read about it:
Have this repair done on your set and it should save you about $1300.00 to $1500.00 on the repair.
Hope this helps.
