Acer P1200 Projector - identifying component & value

[DerekHawker]

Hello, I wonder if anyone can help? I have one of these I'm trying to repair.

Acer P1200 Projector

It sat in a drawer for years, worked for a couple of hours a few weeks ago, and then the following time it was switched on, fizzed, smelt of burning and tripped the fusebox. By coincident, on the same day I borrowed an old tape player from a friend and he mentioned that certain components can dry out if not used regularly.

On opening the projector I can certainly see at least three components that have visibly blown. Two I can identify easily enough by the coloured bands but the green ceramic disc capacitor (?) has lost the section where the identifying marks/numbers would be. Might anyone be able to help determine what I need to buy as a replacement? Please see photo 7. Many thanks in advance for any advice!

It's an NTC thermistor. These are used for inrush current limiting. They do not normally fail in isolation. I expect that one or more of the semis will be shorted, usually the chopper transistor.

To correctly identify NTC, you should provide it's marking on the other side and its diameter. EDIT as I see there is nothing on other side, you need to find a missing piece of its green coating with marking. As of 0.16 Ohm resistor, it's a 99% sign of shorted MOSFET, and another resistor bedside it is probably dead too.

Had a projector board like that for repair a while back.
Like fzabkar said, the problem won't be the NTC, something else blew.
In my case it was a small SMD diode in the PFC circuit which blew the mosfet, the NTC and the fuse.

Thanks so much for your responses. I'll do some research tomorrow based on your suggestions, though I think this may be beyond my abilities/comprehension.
