2007 Mitsubishi 732 series Owner's Thread (57732, 65732, 73732) - Page 82

Not to my knowledge. I think someone needs to conduct a diligent search for it. It's black, about 1-1/2 inches wide and roughly 8 inches long.. This model is now approaching 4 hrs old, so if you find the remote it will likely need batteries.

With the remote you press MENU followed by 2-4-7-0. Hours will appear in the bottom left. Press EXIT to go back.

It depends on how it's been taken care of over it's relatively short life and what's actually wrong with it. Sounds like it's maybe had a hard life by a careless owner. I'm sure you could find a remote. When I bought our 65732 I also saw a 73732 in the store and frankly it didn't do much for me. When watching in 4:3 mode the presentation is simply awful because of the hourglass effect. It's noticeable too on the 65, but tolerable. On the 73 it's really bad. It's also a huge energy pig, both from the standpoint of power consumption as well as heat generated, as anyone who owns one can attest. Tho otherwise in perfect condition, I'm considering getting rid of my 65732 as soon as the extended warranty expires and downsizing to a 55" LED flat panel. When we originally bought our Mits (Sept 06) we put it in the living room and only watched occasionally, evenings mostly. Since moving, it's now in the family room and since retirement we have the thing on constantly all day long and thus the electric co. loves us. Total cost of ownership is turning out to be just too much for an all-day/everyday TV (energy + a new lamp every 12~18 months). An otherwise gorgeous TV. I even had it ISF-Calibrated by Accucal and keep a spare lamp on hand.

It took a full 2-1/2 weeks after talking to Mits and convincing them my problem with trying to use a multistream CableCard was set-related and to finally receive the upgrade firmware. Why they make this so hard to get is beyond me. Nope, you can't download it! You have to call, give your model & serial # and then have a "known problem" that the latest firmware addresses before they will give it to you. They then verify the problem and call you back a week later to tell you they're sending the chip. Geeze....Just because you might want new firmware doesn't mean you'll get it. The latest version is 8.04 (most sets came with 8.00 in 2006 and 2007). If you want to get it, tell them you're trying to use a Scientific Atlanta multistream CableCard and you're getting an error message 161-050 on screen. (Release 8.04 fixes that problem). It probably addresses other things too, but I don't know what those bugs are. (maybe someone here knows and will tell us!!)

Even still it's going to take 2~3 weeks to get it. Mine arrived today, strapped to the belly of a mule (UPS Ground). What you receive is a 4-gig Compact Flash (CF) chip which contains only 18.9 megs of data. Why they used a 4-gig chip for less than 20 megs of data is beyond me.

Anyway, suspecting they might have a self-destruct routine in it, I copied the chip they sent me and burned the data onto a 256-meg CF chip of my own, then used my chip to perform the upgrade. Sure enough, at the end of the upgrade, the CF chip is wiped clean, ostensibly to prevent you from sharing the data with anyone else, God forbid, (unless you were wise enough to copy it first)

The upgrade process is a very specific procedure, but not difficult. You turn off the TV and unplug it - which you must do. Then insert the CF chip in the reader on the front of the TV. Now plug the set back in but don't turn it on. Just sit, wait and watch. Your green power LED will be flashing like mad then after a minute or so will finally stop. In another minute or so the TV will turn on all by itself and you'll see a message come on the screen a few seconds later informing you that the software upgrade has completed. Unplug the power cord, wait 10 seconds and plug it back in.

Finally turn the set off and wait for the green power LED to stop flashing, then remove the CF chip and pull the plug one final time (10 secs) then reconnect, Done. You may have to rescan any OTA channels or CableCard channels you had, but any "settings" are retained (thankfully).

Mits fully expects you to return the CF chip, as they send an envelope and UPS return tag in the package. I've heard of people getting billed for $36 for not returning the chip, so returning it as requested is probably in your best interest. Since they make the process easy and free, there's really no excuse for not returning it. There's no data on the chip anymore, it's been erased.

The upgrade solved my problem with the CableCard.

In addition to the upgrade firmware, the chip contains some potentially useful diag. screens (color bars, greyscale, vertical/horizontal alignment test patterns, etc) so copying first before use nets you these nifty files (16 of 'em in fact)

.

Can you provide a link to the document about the mitsubishi firmware upgrades (versions, fixes, etc)? Thanks.

I would have liked to have seen it.

Supposedly, from the (now 2) Mitsu authorized service centers I've spoken to, Mits holds all information about known performance issues (the secret KPI list) very close to their vest, not even sharing specifics with their own service centers. They won't even tell them what specific issues the updates address. The only option is to call them, describe your symptoms and then wait, often as long as a week, for someone to get back to you. Then if your problem matches a KPI, they will authorize you to receive the firmware and ship it to you. At least when they send out a firmware patch, it is said to be the latest then available. The firmware patch script on the chip even includes a command to erase the chip to try to prevent you from sharing or applying it to another set. Of course if you know this beforehand (as I did) you make a backup copy. I can understand this position, because the world is full of complete idiots. It only takes a moment for some mental midget to destroy his TV by applying a patch that applies to a different model.

The chip contains its own OS (VXWorks), the patch files, several nifty diagnostics/alignment screens (jpg files) and a script to auto-execute it all. It boots up into Wind River System's VXWorks, a small, proprietary OS that's been around for a zillion years and is mostly used in stand-alone microprocessor-based commercial products. It's the core OS currently used in MITEL VOIP telephone systems and previously in their older TDM phone systems. Manufacturers like it because the hackers ignore it. The command structure looks a little like BSD, enough in fact that it likely traces its roots to BSD.

In the Mits, after the OS boots, an imbedded script in vers 8.04 executes a total of 82 separate commands, the last of which erases the CF chip.
Interestingly, most of the script commands are commented.

Somewhere I read Intel recently bought VXWorks ( year or 2 ago)

Bottom line, Mits firmware 8.04 fixes the problem I was having with the Multistream CableCard being improperly recognized. Equally interesting, Comcast tech support was right, they told me I likely needed a firmware upgrade for my TV. Simply amazing.

How much use has the set had since the last lamp change? Absent any other indications, that's the first thing I'd try. Also, while you have the lamp holder assembly out, remove the little fine mesh screen. It tends to become clogged with lint, etc. I've had much improved lamp life since removing it.
