I'm considering buying one of these projectors, but the seller informed me that it has a broken ceramic resistor. Is this an easy repair? Are these readily available? Thanks!
You can get them from radio shack, or order them online- digi-key, newark, etc. and it's only 2 solder points. it might be difficult if you don't solder...
I haven't found these to be that easy to find in the proper value. However, what they do is dim the lamp (form High to Low). If the ceramic is the only part broken - it is common - as long as there is no risk of contact with the projector's metal frame, there is no problem to solve. It will continue to work fine for years. Unless the resistor has been moved or lifted a bit towards the projector's body, it can't come into contact with the body so there's no shock hazard. But determine the position before using it in case the previous user monkeyed with it a bit.
If in fact it no longer works, first, check that the soldered connections on either side are good. If they are, you can either cut the resistor out with strong diagonal wire cutters or, assuming no shock risk as above, ignore it. All that will happen is that you will not have the Low lamp function; you'll only have the High.
