Panasonic PTAE 700U optical block

My optical block needs replaced after 3 years. I've been told all brands do this in 2-4 years . Is this true or did I just have bad luck? I've contacted Panasonic, but they are unwilling to help.

Thanks, Morry

Re: Panasonic PTAE 700U optical block

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

Is this blue tinge on the left side of the screen a lamp problem or the projector itself. the lamp for this Panasonic PT-AE700E was replaced only about a dozen hours ago. what is an optical block, and does...

Your problem is the optical block failing. This is very common with the AE700s. It actually happened to me once before and I had it fixed. After having it replaced, it was recommended I run my fan on high mode, run the lamp on low mode and change the back lit color to black from blue to help thwart the issue. The optical block fails due to heat stress from the projector. Doing the things above lower the heat and extend the life of the block. I have a perfeclty good optical block if you would be interested as buying them new are extrememly expensive.

How do i tell when the lamp needs replacement? I have little blue dots all over the center of the screen like a constellation that keeps getting more dense. would this go away if i replace the bulb?

I haven’t actually worked on this model, but I can tell you that the problem is NOT the lamp. You asked how you can tell when the lamp needs replacement, on the front there is a indictor labeled “lamp.” It will be flashing when the lamp does need replacement.

Being a LCD (quite like the LCD on your computer) over time you can develop bad Pixels. I am sorry I don’t have a fix for you, but I do hope you invested in the extended service plan on this one.
Best of luck to you!

Yellow image produced by DP8200x

the light filter on the blue lcd is fried and needs to be replaced. it makes sure only blue light comes therough that lcd panel. when it's light is blocked from coming through, only the red and green lights can be seen, hence the yellowness (red light+green light=yellow light). it's common with lcd projectors. unfortunately, you can't buy that piece seperately. you need to buy the entire optical engine, which isn't cheap (almost $2000).

Blue points in the screen

This is a recurring problem with this model, along with the 50 and 60 inch models. The problem lies in the Optical block needing replacing. I've heard that Sony, depending on the serial number (or manuf. date), will cover the repair, in some cases, so I would certainly check an authorized Sony service center 1st.
Good luck

Kf-42610 blue hue and blue dots on screen

Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )

Could be the problem they have been covering it under a recall of sorts. $1250 for the optical block and they are only doing it until the end of the year so don't waste any time
