Hello, I have been lurking these forums for some months now. I purchased a Sanyo PLV-70 on Ebay a few monhs back. It has worked flawlessly for a while and now it shuts off after just a few minutes of use. It goes to high fan speed and runs for about a minute then goes to lamp ready state. (Rinse Repeat) I had read some similar issues with remanufactured bulbs so I bought a new bulb and the issue still exists. (I put the old bulb back in the unit.) If the meter was accurate it had only 639 hours on it anyways. I have not found a solution in these forums anywhere and have seen a couple people request service manuals for this unit. I would also like to know if I could get one. If anyone has one it would be greatly appreciated. And if anyone knows what causes this issue that would be greatly appreciated as well. I am hooking this unit up to a PC and watching videos from it. I am new to projectors or audio/video in general though I work in IT and am very tech savy.

Thanks

Mike

It sounds like the lamp ballast or power supply is failing. I don't have a copy of the service manual but one of these folks might:

I was wondering about the balast or power supply from some previous posts I had read, I was hoping to figure out how to check and see which it might be. I messaged Brandon about a service manual. Today I took the unit out into the garage, removed the filters and pulled the top off of the case. Took the air compressor to it and blew out a couple small clouds of dust. Hoping this might make a difference. Unfortunately it did not. Took it back inside and plugged it in to find the same issue. I am not getting the heat warning light or anything. It just turns off with fan on high. After a minute or so of that it goes back to lamp/ready and you can turn it back on and go through the whole thing again. As I mentioned before I am new to this whole field and didn't realize what a beast I had purchased. (Maybe a lemon too) I am wondering if it is worth taking to a repair shop of some sort. And were would I find such a place? Would be nice if there was someplace local rather than shipping the thing.

This might be a good time to add your location to your profile. It's actually almost rude not to (imo) have a location listed. Even just adding a state or country helps. Because someone near you might see the post and speak up.

I just joined the forum and just hadn't got there yet, (added now). I run a forum of my own on a different topic and do appreciate good forum etiquette

I have had a similar issue with my PLV-70. Last year around this time the projector would turn on and the fan would start. The lamp would not light and then the fan would got to high speed for a few minutes then slow and the projector would say it was "ready." Tried replacing the lamp. but that did nothing. I Sent it to Sanyo and replaced the ballast and $300 later I got it back.
About a month ago I used the projector for the first time in months and it worked fine, however the next time I used it I had the same problem that I had this time last year. Does anyone know off hand where I can get a Ballast from? I have tried googling for it but have found nothing...
