Mitsubishi HD Receiver HD-4001

by SilverMetal / July 17, 2008 2:44 PM PDT

Does anyone know where to find a replacement for the Mitsubishi HD-4001 Receiver.

I currently own a Mitsubishi LT-3780 HD TV, and am looking for this audio / video receiver to take advantage of the proprietary features that it includes.

I cannot find this anywhere I look, and I am doubtful that an alternative exists.

I hooked up a PS3 to the HDMI port, and the best I can get is 720p/1080i. I'm not complaining about this, but i'd like to have the full 1080p with the receiver. I've looked at Onkyo, Sony, Pioneer, etc. Recievers, but I can't seem to find one with MonitorLink, which is proprietary Mitsubishi technology, I believe.

Any ideas??

I've been looking all over for the same box with no luck. I found an old auction online that had one, whoever won it got it for ten bucks. If you have any luck please let me know.

I know this is a loooong time since this post was made, but if anyone is looking for a Mitsubishi HD-4001 Receiver/Controller I have one that I can sell, becuase our Mitsubishi tv broke, and we have to box left over.

Hey there, we have a customer that has this outboard box(hd-4001) connected to his Mitsubishi LT-3780D TV. The outboard box seems to be unresponsive to IR commands now (a power cycle seems to fix the problem for a short period of time, but fails again soon thereafter). We have thought about just replacing the TV due to the unavailibility of the unit, but I just read your thread...Do you still have this HD-4001 box available?

Yes, we do.. our t.v.'s panel went out a while back and it was too expensive to buy a new panel, so we sold the tv, but kept the box. If you want more info email me at tjriggs at comcast dot net

- Our HD 4001 media center died recently.
- The TV repair shop said it needed a very expensive circuit board.
- We cannot afford to fix it.

-If you still have your HD-4001 media center, my wife an I would truly appreciate it if you would sell it to us.

I have recently received a Mitsubishi LT-3780 LCD Flat Panel HDTV monitor with the accompanying HD-4001 A/V receiver. The HD monitor section no longer works, but is available for parts.

The HD-4001 receiver, however, is in perfect working order and is available. If anybody would like to purchase it, pls see my Craigslist listing on, dated Dec 23, 2009.

Kindly respond to the Craigslist ad if you are interested

Really need your help.
by darkzero80 / February 6, 2010 12:50 PM PST

Hello sir,

I'm really sorry to bother you but I also have a Mitsubishi LT-3780 and my outboard box isn't working at all. I found you by reading this forum on CNET. I was hoping to see if you can tell me if you have any more or if you knew where I could get one? I've searched everywhere with no luck and i'd like to get this TV fully working.

Thank you so very much,

I only had the one box and it's been sold.
Sorry. All I can recommend is checking craigslist and similar sites nationwide, secondhand stores, and this site. Good luck.
