Sony PWM-EX1 not powering up anymore. How do I fix it?

there are many tiny fuses on the circuit board any of it may be open,replace it.

Here are a couple of links to the manuals, maybe you can find your answer in the operating manual:

Good luck!

the filter cover sometimes gets distorted and the small plastic dimple which presses against the switch doesnt activate correctly, check the lamp cover switch also.

1.unplug power cord
2.plug back in and it should be in stand by mode.(red light on)
3.do not power on
4.on remote push RESET,LEFT ARROW,RIGHT ARROW AND ENTER(do it in less than 5 seconds)
5.after you have done this power on and go to menu and it should show lamp hours 0
6.if it didn't work just do it again, it took me a couple of tries.

Look at Sony Part Catalog. Enter A1539606A at the top of the page and click Search.

Parts store shows this remote as #141861411 but not avail. MCM Electronics has that part number as 1-418-614-11 (RM-SCEX1) under thier order number 32-20405 for $13.80. You may wish to consult your owners manual to verify the number of the orig remote provided before ordering just to be sure.

stereo headphone jack from pc through to AUX, if on your system, via twp rca plugs

I have had the same problem with 3 Sony VPL-EX1s and Sony will not answer emails regarding the problem. Hence I wont be purchasing Sony projectors again.

If your two speakers are working,if ok ,then the problem is in power amp section ,the IC chip there is already defected .changed that IC so it works normal again and some reheating works in power amp.section...
rate me as FIXYA

Hi David

I think you should replace the lamp.
