Ballast Where can I purchase a ballast for an infocus x2 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.

remove the front and rear bezels, remove the top cover, take a picture of the location of screws and ground wire on the metal frame. remove the top boards, remove the metal frame and there is the ballast/power supply. pay attention to the way the cable is routed to the lamp connection, also pay attention to which way the connection from the ballast is seated in the lamp housing. hopefully a new ballast will fix it for you, as to where to get one, that's iffy. you could try to find an in26 on ebay that has other problems but has a working ballast

if you don't hear a high-pitched whir, the colorwheel needs to be replaced. if you do, it's either the lamp or ballast. if the lamp is new, replace the ballast. you can get the parts if you want to do it yourself, or you'll have to send it in. either way, try av solutions in ny. they are an infocus service center and they're really good. www.avsolutionsny.com

first off, many churches and schools hang their projectors from the ceiling, and the only time they take them down is when they don't work. it sounds rational, but it gets dusty up there, and without proper and relatively frequent cleaning, the dust builds up and the projector can't release the heat properly. this causes a lot of malfunctions. the ballast is only one of them.

to replace the ballast:

make sure you can get the part from infocus or an authorized service center. it's part # 525-0085-51. after you remove the cover (4 screws on the bottom. you'll need a T10 torx driver. slowly slide the top forward and lift off), gently remove the ribbon cable by sliding the cable locks (on both sides of the cable) towards the front and pulling the cable out. the ballast is at the front of the projector next to the lens and in front of the lamp. pull it out and remove the ballast from it's housing. there are 3 cables coming off- the power plug, the lamp plug, and the lamp enable plug. remove those and replace the ballast. reverse the steps to install.

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.

Try LumenArc. They stock a range of ballasts. If yours is not listed, then email them.

if the new lamp doesn't have a problem, then it's not the ballast, it's just a bad bulb. especially if you didn't get it from infocus. the cheaper lamps don't last long. you get what you pay for.

more then likely the ballast has gone bad and the lamp is not getting the right voltage to fire. Only other thing you can do is remove the lamp the turn the power on and check the voltage at the connector. This will not check the triggering voltage mine you only the lower operating voltage. But since you have replace the bulb with a known good one I'm betting on the ballast is bad.

you won't find schematics for them. infocus had their boards made by someone else who now no longer makes boards. it's usually the caps drying out that causes power problems.

ebay has several that need bulbs... just a thought here is one of the item numbers Item number: 270207032811
