I recently acquired a used Mitsubishi M-VR600 receiver (without an owners manual), and somehow the remote lost some of its functionality. I did a lot of digging around on the internet and it seems this remote is actually a re-branded One-for-All URC-6050 remote with some of the buttons re-purposed to control specific receiver functions.

In the process of trying to figure out how to restore the remote, I somehow completely erased all of the functionality of the remote. However, I was able to find a CCF file for this receiver on the internet and used another program I found to extract the OBC and EFC codes for the remote.

So my question is, if I have the list of the OBC and EFC codes for each button on the remote, how do I use those numbers to reprogram the remote? I tried using the steps to assign codes to buttons (holding SETUP until 2 blinks, entering 994, tapping SETUP, entering the 3-digit EFC code for the specific button, tapping that button, got two blinks). However, that didn't seem to get the remote to do anything for the receiver.

Am I missing something? Do I need to incorporate the OBC numbers in to the setup somehow?

This has turned into a major challenge that I really want to solve!

No you can't use the OBC numbers directly to manually program the remote. You need to use EFCs. But you need to have a corresponding setup code that has the correct IR protocol, and device number(s). Please post a link to the CCF file. Then we'll see if the 6050 has a suitable setup code that can be modified.

Edited to Add:
The M-VR600 uses the Mistubishi IR protocol, device 119. The setup code that sends this is Audio 1393. I suspect that this may have been added as a custom feature for the Mitsubishi remote, so depending on what you did, the setup code itself could have been erased, or (more better) the setup code has been mis-assigned. It is also possible that the setup code is some other number, but 1393 is used in a number of remotes made by UEI (OneForAll, etc.)
Try assigning Aud 1393, and see if the remote blinks twice. If so, I expect Vol, Mute, and Power to work--maybe everything.

Thanks for the reply. Here is a link to the CCF txt file - this lists the codes for many devices that the creator had incorporated into his system, but I am only looking at the Mitsubishi 119 (which is the first group of lines):

kopriha.txt


Try assigning Aud 1393, and see if the remote blinks twice. If so, I expect Vol, Mute, and Power to work--maybe everything.

How do I assign the Aud 1393 code to the remote?

Thanks again for your help.

Wow! I loooked up the 6650, and it is really old, and uses 3 digit setup codes, aparently. Here's a manual.

I suspect that you'll need to use the 991 code search approach, since I don't have any idea what the 3 digit code might be.

Yep, I tried that already - I went through the "Power - Device" sequence about 200 times. No luck, the receiver never turned off.

Then probably the setup code for the Mitsubishi receiver was added as a custom upgrade at the factory, and has now somehow been erased. I believe that the URC-6050 did not have any Mitsubishi IR protocols built in.

Probably you'll need to get a universal remote. UEI manufactured remotes which carry setup code Audio 1393 include OneforAll URC -8820, RCA RCRP05B, and the Atlas remotes provided by many cable companies.
