I have had a 62mx195 since october of 2006 and its been running pretty good. Then, about two or three months ago I turned it on and got a blank screen (blue light steady, yellow blinking and rebooting itself until both blue and yellow lights binking at 1 second intervals).
I have sound but absolutely nothing on the screen - just black. Cannot get to a menu or anything else. I took out the llamp and it was cold so it was not working. The light looked good (nothing loose, etc). Plugged in another lamp with the same results.
Then called a repair man and he took out the light engine and thought it might be the ballast - no cigar. We then moved the set to an outside room as we had to leave for a couple of weeks and the repairman needed to get to it to check out some other things. We returned and I called the repair guy - he said that it was working fine but he had done absolutely NOTHING. That was about two weeks ago.
This morning I turned it on, had sound but was back to the black screen. Evidently when we moved it we temporarily fixed it. The repair guy seems to have no clue and I know I don't have a clue. My hope is that I have two bad lamps and plan to try yet another but doubt that is the problem.
I called toshiba and spoke to a tech who suggested that I do the 'knock test' on the lamp, ie. with the lens up knock on the lamp as the mercury might have not been fully distributed. I did that, no cigar. He said that I would have to find some kind of invoice to show when I bought the set before he could send me a new lamp. I found an invoice and called back to try and get a free bulb from them as per their offer of a bulb for this particular set and serial number. The tech person (different from the first) started to ask the questions on HER screen after I had explained the whole thing to her (she was not listening - just following her screens). I explained that all I wanted to do was to get a new bulb as per instructions on the Toshiba site and that I had an invoice, dates, etc. She didn't get it, kept asking questions, which I had now answered several times, so I asked for a supervisor but none were available.
Does ANYBODY have any thoughts on this one whilst I am trying to get another lamp (without paying out out another 200 bucks on a system that may be simply screwed forever)?
My other thought is that possibly I could just get another light engine which might be better than the one that came with the set.
