Question about InFocus ScreenPlay 4805 Multimedia Projector

4805sp runs 4 or 5 minutes then shuts down

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?

Hi there

Yeah, thats the bad fault that one. The fault you have described is the main controller board giving up the ghost and stops supplying enough voltage to the fan tp allow it to run, and shutting down after 4 or 5 mins is the safety thermostat on the bulb cutting it out as to not cause any damage due to overheating. My projector had both these same faults, I ended up just buying a new light tunnel after many attempts of glueing mine back together unsuccesfully =(, and to fix the fan issue (without spending $800 on a new controller board), I permanently mounted the insides of an old nokia charger inside the projector, which supplies the fan with its own power source, worked like a charm =D. Yes I would be more then happy to send you the service manual, may I have your email adress to send it to?

Cheers

Heater starts and runs for several minutes and then turns off


Since the unit runs for a couple minutes, I would first check for proper water flow. Find the pressure switch. It is usually round with two wire terminals and a copper/metal tube attached to it. With the wires attached, use a jumper wire to bypass the switch. If it runs longer check for flow problems.. (WARNING don't jump the switch for too long!!! Just enough time to see if the run cycle improves). Clean all the skimmers baskets, pump basket, backwash the filter (if a cartridge filter clean the filters). Try firing the heater again. If it still shuts down, replace the pressure switch. I never recommend adjusting it. Adjusting it too low can damage your heater and/or cause injury.

TV wont turn on, makes buzzing noise and shuts off


I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.

TV Turning on and off by its self


You have problems with a condenser that allow the power supply to maintan an acceptable level of voltage in order to keep the TV on. take to a tech to be fixed. unfortunatelly, this problem needs a tech to take measures in the circuitry to find the component that causes the problem.

TP50G60 bad scrambled picture - shuts off after 1 minute


This does not sound to me like a convergence roblem. It could be a shorted picture tube. That would put the set in a shutdown condition. Normally in Toshibas , the picture remains on with a convergence problem. Here is something you can try, but you must be very careful. Remove one crt board at a time from all three tubes. if the set stays on after one of the crt board are removed , then that is the shorted picture tube.I cannot caution you on how care full you have to be trying this procedure.
