Usually the projection lamp is in a box on one side or the other of the tv., sometimes in the back, there should be a door that you can open, inside there will be a ring that you can pull on to get the lamp assembly out. you need to goolge the set make and model for the correct replacement lamp, look around on the internet to get the best price, you should be able to get a lamp for 50 to 80 dollars. You can buy the lamp already mounted in the slide in assembly but you will pay an additional 30 dollars for that, if your just a little bit handy, you can replace the lamp in your housing and save a few dollars. also be sure not to touch the new lamp with your fingers, where gloves when handling the lamp as grease from your fingers will cause the lamp to burst very quickly. good luck. I just replace one of these and it wasnt' that difficult

The lights indicated that I needed to replace my lamp. After doing so, the TV still doesn't have picture. What do I have to do to get it to work?

It is possible that the Ballast is not turning on the lamp. In past years it had been difficult to get the Ballast separate from the Optical Block but they seemed have them available. In order to replace it you will need to remove the Optical Block which is in the center. The ballast assembly is mounted on the right side of the OpticaL Block. Once the Optical Block assembly is removed, it is not difficult to replace. To order a Ballast, call 1800-631-3811. You will need the model number.
I hope this helps,

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.

Usually at worst,you need to replace the bulb once every year. Life expectancy for a lamp is anywhere from 1000-3000 hours depending on how heavily it's used.

It sounds to me like you've got a power supply issue more so than a lamp issue,if you haven't replaced the lamp recently then I would try that first,if not have a technician look at the boards for a culprit.

Tv stoped working - LIFI PT56LCZ70

This unit has a very complicated bulb replacement procedure. You would be much better off if you contact a panasonic service center and have them replace it. Bulb assy is pretty expensive as well. The part # is LFS4000PA1EB but you will have to go to panasonic to get it. Good luck. Thanks

Three inch red dot appears on my Panasonic tv screen. It is an LCD. Can it be fixed? What do you think it is? The dot shows up mostly on the light scenes.

Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and inspecting the lamp itself and the lens that it shine onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly.

Hey joseph, actually replacing the optical Block is not necessary at all, all you need to do is get into the "Service Mode" of the Tv and change a few setting around, did it a few weeks ago and now my TV looks perfect, no reason to waster $1200 as sony is trying to get over on all us consumers.
