First check wall outlet is bad or a house fuse has blown. Try another outlet. Test / replace if bad: power cord, fuse and on/off switch on projector. If these do not solve the problem, consult a professional service person.

My projector won't turn on, only the power light shows red, the status light is blank. Tried the remote and manually turning it on.


Hello
If the power light is ON and status light is OFF; check if any objects are blocking the air inlet or outlet grill, and remove them if any, and carry out the following.
[1] Unplug the power cord from wall outlet.
[2] Make sure that the projector has cooled off.
[3] Plug the power cord into the wall socket.
[4] Press the power button.
Check whether the cooling fan has stopped. The problem is with overheating itself.
If these does not help you, your projector need service. OK.

Hi my Sony VPL S600 won't turn on at all. It seems like it's not getting any power. I turned it off and a few days later i went to turn it on and nothing, no lights or sound or anything.. What is the...


I know this sounds silly, but check the switch on the back of the projector. There is normally a hardware switch, somewhere around where the power goes into the projector. Make sure this is on. Second, try taking out the bulb, WITHOUT TOUCHING ANY GLASS, and replace it. There is often a safety switch that prevents it from powering up without a bulb. Also, try using a different power cord, or try using a different outlet. If it works with a different power cord, your cord was bad. If it works with a different outlet, your outlet will need to be inspected by a qualified electrician, to make sure there are no shorts or other hazards. If none of this works, contact Sony about getting the projector in for repairs. Please do not try to open the projector your self, there are a lot of capacitors that store energy for long periods of time.
Thank you! Jordan

Projector is not turning on...and turns off when on


if the lamp is good, it could be a fan not working, which would be a bad fan or bad main board. IF the fans are working, then I would have to say that the power supply was bad or the fan laying flat against the bottom in the right rear corner is bad.
