Changing Lamp on Epson Projectors EH-TW5900, EH-TW5910, EH-TW6000, EH-TW6000W, EH-TW6100

I am not exactly sure, what is the motivation here, but Epson seems to sell a projector lamp for these projectors in an assembly, in a plastic case with a lens and a reflector built together. It costs about 300 Euros on Amazon. It is also possible to buy just the lamp itself, the core of the module, and pay only 60 Euros for it! Here I shortly describe my experience with changing the lamp in my TW5910. The procedure should be the same for other projectors with ELP LP 68.

The fazit is to save your money and get one for 60 Euros if you can unscrew 4 bolts and screw them back again.

After a few years of intensive use the lamp in my Epson EH-TW5910 stopped working. The projector blinked red and I had to replace.

I am not exactly sure, why paying for the plastic case you already have makes sense. Maybe it is about comfort, as the new lamp in the case can be simply plugged in into the projector and that is it. Maybe it is safety, as the lamp contains quicksilver Hg, and if broken represents a health risk. But if you feel skilled enough working with a simple screw driver, you can (fully at your own risk and for your own pleasure) exchange the lamp saving almost 250 Euros.

Here is my story. Instead of buying the original lamp, I bought this one: PJxJ LP68. Next, when delivered you'll have to exchange the lamp. Here is how I did it:

1. Put on gloves, better some kind of plastic/resin gloves which do not leave any particles on the lamp
2. Wait until the projector is cold and shut it off, unplug it.
3. Take out the old lamp module out of the projector, you can pull the metallic spring for it. Remember how it should be placed back.
4. Unscrew the plastic body, take out the old lamp.
5. Put in the new lamp instead.
6. Assemble and insert back into the projector
7. Enjoy

Unfortunately I was not able to find a ready video or a photo set on how this is done, but in case of LP68 it was really dead-simple. Much easier than say in this case.

Some things to pay attention to: work on a clean and flat surface, do not let the lamps fall or break, they contain quick silver. Do not throw the old lamp in a simple household trash, recycle it properly, bring it where you have to according to the local law where you live. Insert the new lamp carefully in the casing, make sure a metal spring holding it fits well fixing the lamp steady in place, otherwise the lamp might squeak because of vibrations.

It is really that simple. Seems like this plastic sales story is one of the businesses where the manufacturer makes money on spare parts selling too much and way too expensive for not a single good technical reason imo.

Still, my experience with the new lamp was not exactly very smooth. First, it was squeaking and I had to reassemble. I put some copper grease in between the spring inside the casing and the lamp body. After reassembling the squeaking stopped. If you also decide to use grease there, make sure you use just a few. Use only heat-resistant grease. Make sure that when steaming it is not dangerous for your health, as the copper grease might be if you inhale too much of the steam later. I do not recommend it explicitly, do it at your own risk.

Next, the blue shadowing on the left of the projector's image got bigger. I find it a problem of the projector: the shadowing was there already from the very beginning when I bought it new.

Last, the brightness of the lamp is, in my opinion, better (!) than the one of the original. So in this regard I can only recommend it.

Generally I personally do not find these Epson projectors great. They are noisy and work reliably only in the standard mode. The quieter Eco mode isn't great. The original lamp was flashing slightly in the Eco mode, making web browsing impossible. Interestingly enough, the new lamp does not. Not so noticeable when watching movies, the flicker gets very annoying if you pay attention to the lighter scenes. 3D mode of my TW5910 is actually good, although I do not like the form of the glasses. They get reflections in the inside from all around the room. On the positive side: they are easy to use, and cost not a lot at the time of writing (February 2017).

I hope, my experience here could help some of you to take the decision and save money on the unnecessary spare parts.
