I bought a Sanyo PLV-Z4 a few years back, brand new, from visual apex, after much research on here. It's served me pretty well for occasional movies and PS3, but relatively low usage overall. After 100 hours or so, it was hit with what seemed to be somewhat common, flashing replace lamp yellow LED + red power, and the PJ would shut down, or not light the lamp and turn off. Solution was to open it up and press the thermal switch back in. I suspect a design or component problem, as the filters were always clean, etc., but 'lived with it.' Loved the PJ, but always annoyed about having to reset the thermal switch monthly or so.
Now, with ~300-350 hours total lamp time, same behavior but the thermal switch isn't 'popped,' so can't be reset. I probably should have sent it off for servicing while it was still under warrantee, but of course, it's now out. Considering what I spent on this thing vs time used, it's cost me ~$7/hour so I'd like to get it repaired vs discarding.
It seems possible that the thermistor switch needs to be replaced. I did remove the lamp which seems to be ok - if anyone knows the proper testing process for the lamp, please enlighten me; I'm assuming it's simply testing as not open = good?
If anyone has any suggestions, I'm all ears, otherwise I'd gladly take recommendations on repair places, preferably one that won't rob me blind. :-/ Any suggestions? (I'm on the east coast, would prefer to ship it along the coast but other/any recommended options are worthwhile..)
