My Acer H5360 has worked fine for two years and 4450 hours on the same bulb. Now I have two dead pixels and I fear more. I love the projector and would like to keep it but I probably need to replace the DMD chip myself but I'm having a hard time trying to find the chip number without first disassembling it. Has anyone else attempted this or should I just quit being a cheapskate and buy another projector? I just bought another bulb, so I would hate to throw that money away.
