I have a samsung projector(model SP-H710AE) which I have owned for about a year. I recently began experiencing problems where the image on the screen goes out but the machine is still on as if it is functioning properly. The temp. light does not come on, and the fans still sound fine. It is dire for me to get this machine working. Can u please help???

Bit of a common problem with Sony projectors of the era that they often had problems with fading and/or cracking of one or more the LCD panels - especially the blue ones for some reason, leading to the type of problem you are experiencing. No point in swapping components either as they will both have similar faults - although replacing an LCD in a video projector is almost impossible without the manufacturers jigs to mechanically align them afterwards anyway...
ist der beamer nog innerhalb garantie, dan bitte zuruck zur lieferanten, am sonsten kan mann versuchen die kappen weg zu holen und die ganze sache von innen aus mal richtig zu sauberen, staub kann die sensoren storen, weicher pinsel und staubsauger konnen helfen.
It's not that easy. The SP-H03 accept VGA input through the D-Sub connector. Mac book does not have this output directly. So you need another piece of adapter for the MAC Book to provide VGA output. It would come out from your Mac "Display Port /orThunderbolt port". Another way is to use a USB to VGA adapter for Mac.
Probably a power supply problem. Most likely, there is a power transistor or relay that is not properly powering the light or other equipment. Check the warranty on the device, get a new one if you can. It won't be easy to fix.
Alot of people are having image quality problems with there projectors. I had a similar problem recently. You simply need to get it cleaned. Sometimes there is a high dust build up inside the optical prism of a projector which distorts the image over time.
I had mine cleaned out by TP Matrix Projector repairs after there were lots of coloured dots on the image.
They gave a free quote and then the service was quite a decent price in comparison to others.
have it checked out for a free quote and see what they can do. there number is 0161 626 4067.
If you have not already found out, your problem may be a Light Tunnel Failure. It is common and can be corrected DIY. Replacement part is nearly non-existent and manufacturer repair is expensive. For additional info go to www.avsforum.com and search for "4805 Light Tunnel". You will find threads about the problem as well as fixes. I also posted a DIY replacement option as well: www.avsforum.com/avs-vb/showthread.php?t=1304694
Sounds a lot like a heat problem; the unit may not be running hot but there may be a bimetal thermal switch that has become fussy.
If you have an electronics supply nearby, they will have 'freeze spray' and if you procure it, you can see if the projector will turn back on if you give it a shot in a vent.
Do NOT spray it on a hot lamp; it may cause it to fracture.
I would also keep it out of the reach of kids since it can impart a nasty 'burn' if misused.
If this does make it turn back on, you will have to come back and seek help in locating the failing switch although the common ones are disc-shaped with two contacts coming from them.
This construction is failing in 100s of thousands of drip coffee makers too.
Either the lamp needs to be replaced, or your projector is experiencing overheating problems. The unit may not be running hot but there may be a bimetal thermal switch that has become fussy.
