Epson Europe EH-TW4400
Projector Specs
Projection Calculator
Hello,

I am new on this forum and before starting I would like to thank everybody for the forum and projector central. Thanks.

I have a problem with my projector Epson TW4400 and the image is not nice at all.
I got a new Lamp 10 month ago and it is now around 500h.

When i look at the Epson logo at the boot of the projector, I have a dark side on the top edge. It is not a straigh perfer line.

Also, the white letters on the screen are "shining" too much and are "melting" above and below... When i turn the lens, these white blurry lines are moving also. The nicest image (non blury) is when these lines are vertical...

I just clean the air filter and the projector with a vaccum. Took out the lamp to have a loook and put it back... it is the same :-(

Please Have a look at the image and pleas advise me.

Thanks

Did you use a Epson branded replacement lamp, or a generic 'OEM' replacement?

The issue you are running into is not obvious, but may be optics melting due to a poor lamp replacement. This effectively will have destroyed the projector if that's the case.

Thanks for your reply AV_Integrated.

I replaced the lamp a year ago.
The problem is only recent... I would have melted before right? I used it more than 500hours.

If it is a problme with the optics that melted like you said, as i am king of a DYI guy, could you explain me what I should do ? Open en clean the optic? Or how much could it cost in a shop?

Thanks

Much like sticking past in boiling water doesn't immediately make the past soft. An out of specification lamp won't necessarily melt optics right away.

I have taken a projector apart recently, and the optics are a very time consuming process to get to, with a lot of connections between which could be damaged. As well, most optics sections cost several hundred dollars to replace - for just the parts.

The lens of a projector is like a camera lens - you don't disassemble it, and it doesn't have replaceable parts. You just swap it out completely.

It's a good projector, so I would probably send it in for repair. These aren't like many appliances with interchangeable parts and unfortunately, projector repairs shops are far fewer than appliance repair shops. If you want to pull it apart yourself, I have no information on service manuals, or schematics which could help you out.
