InFocus LP530 with burnt original power unit. To use a new bulb, what is required to upgrade the power unit? (Apparently, 5 resistors need to be changed)

You can try removing the main board & reseating it. Also try plugging into another outlet & make sure the plug has a ground prong on it. Itshould have 2 flat & 1 pin shaped prongs. Otherwise the clicking sound may be the lamp trying to ignite. Normally when you plug in the LP530 the green power light is on steady & then you press it to start the lamp. If its flashing as soon as you plug it in it's likely that the main board is bad, the button board is bad, or the ballast/power board is bad.
You should remove the lamp & inspect it. It should be clear without bulging in the little bulb behind the lamp glass. I service LP530s all the time & something like that is usually the main board.
Good luck,
Jim

The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work get a small fan and place it near the projector ro provide extra cooling. The projector is running border line on high temperature and just needs a little extra cooling.

This is a clear indication of a new bulb requirement

the colorwheel needs to be replaced. the projector won't turn on if the colorwheel motor is not up to speed.

First try a firmware upgrade. If that doesn't help, it seems it might be a power supply issue since you said the led comes on very light. I repair these power supplies. My ebay id is gtitubro

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

the power supply needs replacing. sometimes the caps are dried up, but show no signs of damage. when the caps doesn't work, the ps doesn't work.

the power supply needs to be replaced. it goes after a while in this model.

I called InFocus and was walked through several steps to determine if it was a bad cable or an internal problem. My InFocus unit would power up and stay powered up with no problem until I connected it to the computer using the analog computer cable (blue connectors). They had me try it with a different computer and then with the S-Video cable. Each time the InFocus unit powered down within seconds of connecting to the computer. The problem is internal. The unit had to be sent to InFocus for repair ($180). If the unit works with the S-Video cable then your problem is a bad cable.

depends on how many times the orange light blinks also when you replaced the lamp did you do a timer reset? you can find alot of information on how to trouble shoot this www.infocus.com/support
