Inserting the power cable, you can hear a whine from the power supply as it powers up for about 10 seconds before that is replaced with a higher pitched whine from then on. Power/status LED’s don’t light up, the fans don’t run, the lamp does not power up.

When I first received this projector, I stripped it down to take a quick look and put it all back together, and it turned on! It stayed working for a few days until one day during operation it died again.

What I have tried so far:

• I have replaced the power supply entirely as I believed it was not providing power properly to the board (replacement power supply shows exact same behaviour as previous one)
• Searched the processor board over and over again for obvious bad caps with a multi-meter (I am an absolute novice at this, so it’s possible that the board is shorting or something and I just can’t find out where). Part of me wants to doubt it’s the processor board simply because it was working totally fine just a few days ago

What is most likely to be the problem? I’m most confused because after my first strip down the projector started working again totally fine. I should mention that when it died again after my first strip down I was moving the projector and believe the power cord shifted slightly, which is when it died.

Note: I have tried powering the projector on with the lamp cover on etc… as I know that the projector won’t power on without the cover. The fans/status lights should power on whether or not the lamp cover is attached.

Here’s a video of me inserting the power cable, if you turn your volume all the way up you can hear the power supply

However, I am torn on the lamp, having 3,523 hours on the clock. The ELPLP67 is rated for 4k hours on normal power, 5k on Eco (probably less with a mix, I think this one had 3.2k normal, 300 hours Eco). I still have ~750 hours left on it, but it's so close to the rated limit I'm wondering if it's worth keeping around or not.

Is this worth keeping as a spare lamp (noting the high hours) or a tester, or is it time to hang it up and say goodbye to this lamp? I replaced it now so I didn’t have have to worry about it anymore as the counter was not right on the unit since I reset it to clear the nag since some projectors shutdown when it’s “consumed”. I don’t think Epson does, but I wasn’t quite sure.

We bought an Epson Home Cinema 1080 3LCD projector that keeps turning off because it constantly says it’s overheating, even when it’s cool to the touch. We cannot take it to Epson for warranty, and I’d like to fix it myself. I can’t find the parts online, so if there’s any other temporary fix I can do I’m also open to suggestions. So far people have said “just buy a new one” but I don’t have another $800 to dish out at the moments. Thanks!

I was after the service manual for the Epson EMP-TW680, the file available is for the TW1000 which has the same power supply. Whats the point of offering somthing that you can't have.

Do anyone have any idea how to fix it? Is possible to solder only wires of the fan to the board (without connector)?

Thank you for your advices.

My idea to solve it which failed.
