Well after 870 hours my Panny 100's gone Pop. Here's what I found on taking the bulb out! Total carnage! Unfortunately some of the shattered glass managed to get inside the PJ itself. I hope it hasn't damaged any of the optics. BTW Someone must have replaced a bulb on these forums. Anyone found a good price. Cheapest I've found so far is from TSI Europe. £227 inc VAT and delivery. Anyone dealt with this company?
