Are you referring to the bulb? If so it depends on total hours used...a common bulb use is 3000 hrs. That is if it has not had rough usage....which was the case with our projector at The Salvation Army Citadel / church. If the projector is turned off before properly cooling is allowed...the life span of the bulb diminishes quickly......God bless, Capt. Hannu

According to the manual you are not getting enough airflow which would explain the optic block failure. Make sure the TV has lots of space for air around it and is not inside a cabinet that would overheat it.
This is not illegal. If you were purchasing the part outright, the core charge would be included in the cost of the part and then you would be able to keep it. Not sure why you would want the part anyway, but most replacement parts do have a core charge. This is true for automotive, appliance, and many other industries. Also, just so you know, the optical block that Sony is providing you will be far superior to the original unit. The color performance and optical block life were improved greatly with the revisions Sony made to these units. Sony is the only LCOS manufacture that actually addressed and corrected the problems that occured with this type of display. You should let them do what they need to to get your TV back into working order.
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!
Reseat the lamp. I had a similar problem. Replaced the lamp and everything worked for about 3 hours. Then, turned the projector off. Next morning, when I turned it on, nothing. Stanby/On light flashed green for a minute then the lamp light came on and the projector went into standby.
I had the same problem with my 4 yr old Sony KDF60WF655 rear projection set, and I was fortunate to buy a 4 year extended warranty - because it was the "Optic Block", ($1300. -not incl labor), that was replaced to fix the problem. That part contains all new LCDs, & multiple Lens & some electronics. I had already got a new bulb (under warranty) a few weeks earlier, that I had not yet installed so the service guy did replace that as well. (This happened 3 weeks before my warranty ended).
He told me that he replaces hundreds of Sony Optic Blocks every year and that many Sony Rear Projection sets have automatic FACTORY extended warranties (up to 10 years), because of some known problems with the blue LCD panels. You might want to contact a SONY office & see if your set is covered.
ALSO - The tech checked my Service Codes & showed me the TV had been running for 10051 hours in about 4 years - on the Original bulb! He was quite surprised because he said the bulbs usually last about 5000 - 7000 hours. He also said it's good to replace them BEFORE they go bad, because they can sometimes burn out the amplifier that powers the bulb, (which is a seperate piece that attaches to the outside of the Optic Block). My TV is like new now.
When I purchased the television iI was told that I would only need a HDMI cable to connect the devices together, this is not true as the HDMI only provides 1 way transmission, to get the sound to go from the television back to the home cinema you need to use either a Phono Lead or Optical lead, plug them in and Hey Presto it works.
Check with Panasonic. I have the same issue and was originally told that the optic board needed to be replaced ($1700). I waivered on getting it fixed and spending more than the tv is worth. So I now learned that there is a new fix for the bad optic board and Panasonic is repairing it free of charge. Repair is schedueled for next Friday (Feb 1, 08). I'll report back if it was successful. This repair involes an eprom on the optic board. Hope the sheds new light........
Check the thermal sensor fuse part# 1-910-023-93 or possibly one of the four fans.
If the unit goes into Fan/Thermal Protect shutdown (4 blinks) it can be difficult to determine the cause since the unit turns off too quickly to troubleshoot.
Solution: Ground the data line by inserting a jumper between pins 3 and 6 of CN44 on the H4 board. This overrides the protection circuits for troubleshooting. Do this right after turning the unit on and as soon as the lamp is seen lighting. Check pins 2, 5, 8, and 11 of CN6000 on the G2 board for less than 1VDC. Any voltage higher than that indicates a faulty fan. If all voltages are within specs, the H4 board must be replaced. If a fan is found defective, the optical block will need to be replaced if it is located inside the assembly.
H4 Board Part Number: A1054674A
Replace the following part based on which pin of CN6000 is out of specs:
Pin 2: Fan 1 (part of optical block)
Pin 5: Fan 2 178723211
Pin 8: Fan 3 178706511
Pin 11: Fan 4 178708111
