Sanyo XE-40

Apparently there is a heat switch on these projectors that prevent them from coming on.
Does anyone know how to reset it.

Gromit has a service manual for these.

If I recall there's a small switch under the lamp access panel, might require removing a few screws though.

See attached - but no resposibilty taken for any damage resulting from following these instructions - which i got from the web - etc.

It can be a bit fiddly if you aren't used to taking these things apart.

I found going in sideways under the board worked better than going down the access hole illustrated. The switch is quite obvious when you see it and doesnt need a lot of pressure to push back home. I did have one though where it wasn't the switch so don't go forcing it!

Is it still in its first three years , if yu give me the serial number i will check for you.

It is not a switch it is a trip, it is a manufcturers fault with this model.

Sideways under the board worked

Got a similar problem with a Sanyo PLC-XW57, anyone found out if these have a similar thermal reset switch/trip and if it can be reset in the same way? It just powers up with fans running for a while then just goes to power led red, no lamp light etc. Teacher had been reporting it was tripping out on overheat but the filters were being cleaned very regularily because of this. Image had started to become dull as well although the lamp hours are very low (checked last week ehn reported that the image was not as bright as it used to be).

Fantastic :) I managed to do this with ease. The best way I found was just removing the fan section. You can get to the switch easily that way x

hi, i'm having a problem with my SANYO XE 40.

When i power it up the green light comes on and i can hear fans power up... however after about a minute the POWER light turns red and start flashing, then it powers down... i've tried the steps in this thread but it looks more like a button than a switch and can't be pressed.

The lamp looks ok? and the 'replace lamp' light isn't on..

any ideas?

If it powers up then down it sounds like it could be a soft thermal trip which won't need the machine pulling apart. Have you cleaned the filtersor checked the lamp timer.

I've cleaned every spec of dust off lamp and filters, i don't know how to check lamp timer as i can't get anything on the display

What is the soft thermal trip? does it need to be reset?

No, if it gets hot it will close down till it is cool enough to operate. If it gets too hot the physical trip will go and the projector won't turn on at all until it is reset as explained above. If the machine is turning on and then turning off then it isn't that switch. There are some settings within the service mode that increases that max temperature and fan speed to make that less likely, but it is noisier and you can mess up other settings if not done correctly.

I'm not an expert though, but that is my understanding.

Thanks for that. I'm at a loose end.. I don't want to buy a lamp if it's not the lamp as it's really expensive, and i don't want to pay for support (out of warranty) if it's just the lamp. lol

Does it sound like there is an internal error or is it the lamp?

Had this ourselves and we got it reapired under warranty, they reported it as being a "bulb fault" what ever that means.
