Question about InFocus ScreenPlay 4805 Multimedia Projector
Have had 4805sp for 4 yrs and love it. No problems until last week when the infamous light tube problem reared its ugly head.With the help from a thread on AVS FORUM I attempted to fix the light tube.The only really hard part was getting the pj on without breaking the plastic. After closing it up I turned it on and found I had indeed fixed the problem. This is the problem. The pj will only run for 4 or 5 minutes and then shuts down. I have repeatedly opened and closed the pj looking for something unusual. I noticed that the fan behind the color wheel is running but the fan behind the lamp is not. Can you give me some info? Also, I noticed that you offered to send someone the service manual. I didn't know there was such a thing and have looked all over the internet for it. Would you please send it to me?
I have the 4805 model and it has been great for 4 years or so, although it powers up as usual there is a whining noise coming from the PJ and then the picture goes off??
Can anyone help with this?
Could be the fan should be running to cool the lamp. there could be temperature sensor that is why it is shutting down to save your lamp.
check the fan if it has continuity. it could be broken and need to be replaced.
tnx 4 using fixya,
