Second, the light engine for the 50HM66 is $169 + shipping and that is when they are in stock and currently, they are not.
Finally, remove the Light Engine from the TV to gain access to the lamp fan. Use your $20 service manual (I could have saved you that $20 had you given me your email) which will describe exactly how to remove it. Be careful when doing so, don't knock it into anything. While it is out, clean the TV interior cavity and clean the single lens on the light engine. Preferably use SPRAYWAY glass cleaner found at most hardware (home depot) and grocerie stores, the bigger stores anyway.
Should you decide to remove the front bezel, follow the service manual. Ezy-peezy. Clean the mirror with care, clean the cavity (dust is usually minimal on these).
For the picture quality of my 56HM66, I would have to spend substantially more than a new light engine and 4 or 5 lamps to get the same size and quality picture in my opinion. I plan on keeping my set going for years to come. I never have been able to figure why someone would buy a TV for $1600 (my set), use till the lamp blew, then buy a new set and selling the old (again, mine) for $50 (what I got my set for). Their reasoning being they don't want to buy $120 lamps, but would rather spend $1000 on another set that likely won't last as long as the DLP did. Just makes no sense. But then again, I wouldn't have my set if people didn't do that so...better for me I guess.
I suggest you keep that fine TV going if the pic is as good as mine is don't think twice about it. Everytime the lamp gets replaced, the picture is just as bright and fresh as the day you bought the set (if the lens and mirror are cleaned).
And to bring this post to an end, if you can't find a lamp fan, let me know, I have one I could sell you.
Yup, $250. I live in Winnipeg, Manitoba, Canada. It was a *real* Toshiba part - was scared to go with a knock-off.
And I should have mentioned that I actually downloaded the manual for free. But thanks for your offer. I would have taken you up on it if I wouldn't have found this one.
Now for some updates. I've been doing some tinkering.
(I decided not to end this thread, because maybe it'll be useful for others too).
Remember I told you I couldn't tell if the lamp fan was working because you couldn't see it when you put the lamp assembly in and the lamp cover door? But you COULD see the fan if the lamp cover door wasn't on there. Well, I decided to remove the lamp cover door, and hold the "safety switch" in by hand, and try the TV again. This time the TV stayed on for two or three minutes! I could see the fan - it was turning. I was pretty happy. The only thing I had done was to make sure the little plug for the lamp fan was securely in (this is a little plug with red, yellow, and black wires, just to the left of the DMD fan cover). I thought that this may have been the problem.
So, for my next step, all I did was put the lamp cover back on (at this point, the back of the TV is still off), and try the TV again. This time, it cut out within 2 minutes. Darn!! I guess it wasn't fixed.
So, my next step was to once again remove the lamp cover door, jury-rig the safety switch (without me having to hold it), and try the TV again. Currently, it has been running successfully for about 30 minutes. Yahoo!!
Now to determine what the problem is. Is it an overheating problem when the lamp cover door is on there? Why would that start now? Maybe the fan isn't running as fast as it's supposed to? (don't know how to check that). Could it be a temperature sensor (thermostat?) that is malfunctioning? Could it be something to do with the lamp generating more heat than it's supposed to? Questions, questions.
So I'm going to leave it like this for a few hours and see how it performs. If everything seems okay, I'm going to put the back on again (but leave the lamp cover door off), and see what happens.
By the way, I never did try to take the front cover off. When I looked at your picture, it didn't look like there'd be any access to the lamp fan from there. So I assumed that I would have to remove the light engine first to get at the lamp fan. I'm glad you confirmed that.
I'm going to go back to your earlier posts to find out where you were ordering your light engine and lamps from. I'm starting to get convinced that maybe this is "worth it". I've always like the picture from my Toshiba, so why shouldn't I try to save it. As you said, it's still way cheaper than buying another big screen TV.
I'll let you know what happens. Again, thanks for your help.
