Lady took name, address, model number, serial number and asked questions about if they were still there on different sources. Did not ask how many. Came up with free chip and $200 labor charge. I pointed out that this was a known problem, and that TI was covering the chips. She continued with chip and $200. I asked if there was a supervisor I could talk to. She went on hold for a while, came back with there wasn't a supervisor available, but she could do the chip, a free bulb, with still $200 charge. I explained that I already had a spare bulb and that this was a warranty issue with TI and I didn't see why I was getting charged anything. She went on hold to talk to a more senior person. I expected her to come back and drop the charge to $100, but she came back with free chip and no charge. She did retract the bulb offer. They emailed me a release form (basically saying I wasn't going to sue them). I scanned it and emailed back. Sending chip to local (50 mi) authorized repair shop. Will call for appointment when it arrives. Pretty painless.
An update on my chip replacement. After a couple of weeks waiting to hear from someone, I got a call from Mitsubishi. The closest Authorized Repair Center they could find was in Des Plaines, IL, about 200 miles from me. I was not in their service area, but if I would drop my 82837, they would do the repair in the shop. Wow. The Mitsubishi lady said if I could find someone closer, they would talk to them. I opened up the Mitsubishi web site, looked up Authorized Repair Centers and came up with 7 within 75 miles. I picked one, called him, he knew all about the repair, but needed a repair order from Mitsubishi. Called Mits back, gave them the name and phone number. From there it took less than 2 weeks to get repair completed. Imagine! They can't even find their own Authorized Repair Centers on their own website.
About 5 months before the chip issue, I replaced my bulb with one of the Philips OEM PHI/334. It really had POP! Vibrant color, great brightness, etc. However, after the DMD chip replacement, the picture was a lot darker, less vibrant.
I haven't been able to get it dialed back in. Any thoughts?
