if you can get a menu when you press the menu button, reset the settings to factory default. if you don't get a menu, the color wheel or the dmd chip is bad. either way, you'll have to replace the entire optical engine. and unfortunately, infocus no longer has any more in stock.
it's the fan. if it won't spin full power, it can't cool down the projector and it'll shut down. there are 2: 60mm (part # 526-0153-00) and 80mm (526-0152-00). both can be purchased from infocus or an infocus service center.
first off, make sur you have the right lamp (sp-lamp-009, 2 white wires. not the sp-lamp-018, one white, one red. the wires are in different locations in the plug). if you don't hear the colorwheel whirring, that'd be the next step. however, you cannot buy just the colorwheel. infocus does not sell individual parts of the optical engine. but that wouldn't matter, seeing as how they don't sell the engine anymore. also make sure the lamp door is completely closed. there is a peg on it that activates a switch to let the projector know it's closed. if you remove the lamp and use a flat-head screwdriver to activate that switch, turn on the projector. look inside the lamp housing and see if the colorwheel spins. if not, i think you need a new projector. if it does, check the fans. they can be replaced.
Hello, Well there are only a couple of things that could cause this problem. However considering this all started when it was mounted consider the possibility you may have used screws that are too long and are is/are subsequently shorting something out.
I have changed the bulb on my LG projector recently. I found the rotating colour wheel to be full of dust. Upon opening the cavity where the light is redirected and reflected onto the imager, I saw all mirrors also had a layer of dust. I don't think it was so dirty that it affected the brightness of the image, but I cleaned it anyway using an earbud. I cleaned both sides of the color wheel as well. You need to be careful in working with the optics of the projector!
Hello Carmen, Well this can usually be caused by one of two things. #1 the main board has failed and needs to be replaced. #2 The firmware's flash data has been corrupted and need to be re-flashed. Both of these solutions will need to be performed by an authorized technician. I have parts for these projectors if you want to learn more regarding this you can contact me at, firstname.lastname@example.org
the same functions should be able to be accessed via the remote as well as the keypad on the projector. press "menu", settings, system and de-select "rear" or "ceiling" whichever is causing the "inverted" image
