Bought an LP640 going cheap on eBay with reportedly failed lamp.
NP i thought.........heh! WRONG
I suspected perhaps the lamp reset might need.....er....resetting.
Thing is, the projector reports "lamp failed to strike" on the top panel LCD, and is stuck in a loop.......I can't get into any menu's or anything.
(Fans run, buttons and LCD light, and LCD says as above)
Pulled the thing apart, can't hear any high frequency noise as you'd expect from an HV generator......so suspect the HV board might be duff.
Clearly SOME power is coming out the main PSU.
Looking at the lamp PSU, nothing is obvious, except perhaps for some discolouration on a small coil.
Looking further I saw optic problems........bummer!!
After the first mirror there's some kind of glass prism maybe, which has partly fallen apart.
The next bit of plastic filter is melted onto a glass lens.
Furthermore, one of the 3x LCD filters is melted.......bummer x10 !!
Well, I bough ANOTHER LP640 which is yet to arrive and reportedly dead (prolly main PSU issues as many other Infocus').
Hoping I can salvage some parts to make one good one.
Anyone care to speculate on the primary reason this LP is failing to strike the bulb and looping??
Could it be something other than the lamp PSU?
Any help gratefully received.
[ I'm in the UK and would be pleased to hear where I could source PSU repair components readilty for the Infocus, if/when I might need them ie Viper, etc ]
