I have a infocus SP61MD10 DLP TV that I bought in Jan 05. Lamp went bad about a month ago, it has been telling me for about 3 months it was on it's way out (Flashing power light 5 times) so no surprise to me when it went out.
Found a replacement bulb only for $200 a lot better than last time at $480, put it in easy enough, plug the set in....nothing, no sound, no picture, no light, no fans.(except over the AV input board)
All I get is the control lights (menu, CH up and down, Vol up and down) and power light. Called the help line at infocus ask for some help, the tech told me to perform a Master Restart by holding the CH down and Power controls at the same tine for 15 sec.
Nothing, tried it on the remote still nothing, so the big question is if anybody knows, how can I perform a master restart other than using the front panel????
Here's my question you replace just the bulb and not the balanced if so there are three wires that go to your fan check them and see if they're brittle if they are you can change the wires I went up to a bigger wire can't get too big the center wire I believe is the one that makes the TV come on the other two wires are what controls the fan I read if you take a nine vote battery across the terminal of the fan Connector battery will only set one way to make the fan come on so If it doesn't come one try it the other way this may or may not help good luck if they're brittle replace them you'll be surprised

Most likely the lamp is burned out. Check the lamp and if it is bad, replace it (unplug projector while you replace the lamp). If it turns on, reset the lamp counter and you're all done!
Be sure to weigh the cost of the new lamp vs replacing this 6-8 year old projector!
It is not a common problem. Ballasts rarely need repairs. Have you reset the lamp hours to zero after installing new bulb? If, yes to confirm about ballast please ask the TV repair shop man whether previously he had repaired any DLP projector. There is lot of difference in technology of DLP projector & TV (except DLP Projection TV).
The problem could be in the projector main board. The lamp lights after getting Lamp ON signal from the projector main board. As the lamp ignites the ballast sends the signal of Lamp Lit. If the projector board senses that any blower/exhaust fan or colour wheel is not running then it will send a signal to Switch OFF the lamp. If you are tech-savvy then do as follows to check about lamp & ballast. Remove 5 pin connector from the projector. Connect projector to mains supply. Get a 5V DC power supply. Connect +ve to pin 3 & -ve to pin 4 of the ballast connector from this supply. The lamp should light. If it does not light then there is problem in the ballast (if the lamp is new). To give a chance you can check it for your lamp which lasted 20 minutes. Generally ballasts are made by OSRAM. You can get the ballast from OSRAM dealer. You will need the part number for that. Take out the ballast, it is there on it.
Yes it is normal, but there were issues in the past with the lamp burning the lamp cables. Infocus then upgraded the cables with slightly heavier gauge wire and better thermal tape around the wires. It would be hard for me to tell you if yours has the upgrade, but if you got it from Infocus I'm sure it is good.
possibly the colorwheel. remove the lamp and see if the colorwheel is still there (colored glass through the hole). if it is, replace the lamp and turn the projector on. if you hear a high pitched whir, the colorwheel motor is ok. if not, it's one of 2 things: the main board has come loose from the dmd chip board, or the main board (eca controller) is bad. if the board is bad, you'll need to replace it, but it's over $500.
if the lamp is new, it could be the power supply (the ballast is built in to the ps). but make sure you have the right lamp. the X1 and X1a have an sp-lamp-019 and the similar X2 and X3 have an sp-lamp-018. the lamps are almost identical except for the wire configuration on the lamp plug. make sure the wires in the plug match the positions in the socket. also, when you turn it on, if you don't hear a high pitch squeal, the colorwheel is not working. and if that isn't working, the lamp won't either. also check to see if the lamp door is closing properly and hitting the switch at the top of the opening.
