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

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.
dcamp77262, you mention that the new lamp worked for 45 minutes and then the dark spot appeared, was this the same with the previous lamp and was the previous lamp the original that came with the projection unit? If you're using a replacement lamp(not original equipp) won't be the first time that they send a lamp that does not match the ome lamp, it also could be (very possible) that you're going to need light engine replacement or repaired.
Power issues (Tv not turning on) were typically due to faulty ballast.
While the TV reports a bad lamp it is the ballast itself causing the
issue. Samsung is well aware and will replace both the ballast and the
lamp (since the lamp can be prematurely aged but the bad ballast).
After replacment most people stop having issues.
