Any one have the discretes for a Mitsubishi WD-73833 or similar?

I found this reply to this same question on this board. I'm not sure who posted it but it worked for me:

Here is what you are looking for.

Applicable Remote Controls and Televisions
This document applies to the full size Mitsubishi television remote controls introduced in 2006. The inputs specified below apply to the TVs that included these remotes. If a model does not have the specified input, or there is no connection to the specified input, the TV will not respond to the direct access signal. The 731 series TVs have a PC DVI-I input, however these models do not respond to the PC DVI-I access signal.

Procedure to program the remote for special direct access functions:



Set the Device Select Switch at the top to the TV position.
Press and hold the POWER key until it flashes twice, then release the POWER key.
Enter in sequence the code number 0,0,0,9,0. The POWER key will flash twice after the first 0 and then flash twice again after the final 0 to confirm a successful code entry.

The following keys will change functions:
POWER - Power ON only.
STOP - Power OFF only.
PAUSE - AV RESET (resets audio and video adjustments).

INPUT followed by 1 - INPUT-1
INPUT followed by 2 - INPUT-2
INPUT followed by 3 - INPUT-3
INPUT followed by 4 - HDMI 2
INPUT followed by 5 - COMPONENT-1
INPUT followed by 6 - COMPONENT-2
INPUT followed by 7 - COMPONENT-3
INPUT followed by 8 - ANT 2
INPUT followed by 9 - ANT 1
INPUT followed by F1 - HDMI 1
INPUT followed by F3 - PC DVI-I Input (not available for 731 series)

FORMAT followed by 1 - STANDARD screen format
FORMAT followed by 2 - EXPAND screen format
FORMAT followed by 3 - ZOOM screen format
FORMAT followed by 4 - STRETCH screen format
FORMAT followed by 5 - STRETCH PLUS screen format
FORMAT followed by 6 - NARROW screen format
FORMAT followed by 7 - WIDE EXPAND screen format

IMPORTANT: When using this remote control as an original source remote control to program a "learning" remote control or Home Automation control system, the INPUT and FORMAT keys do not send signals. These buttons are simply used as a "switch" function to prepare the remote control to send the correct input or format signal when the number key or other specified key is pressed.

IMPORTANT: This remote control was included with TVs that had Auto Input Sensing. Direct access to inputs that have not been connected and added to the active input list is not possible.

Procedure to return the remote control to normal consumer functions:



Set the Device Select Switch at the top to the TV position.
Press and hold the POWER key until it flashes twice, then release the POWER key.
Enter in sequence the code number 0,0,9,3,5. The POWER key will flash twice after the first 0 and then flash twice again after the final 5 to confirm a successful code entry.

Thanks. The TV is due to be delivered on Monday and I will try these settings.

OK all work but I don't have an Input 3 even though the TV displays input 3 when selected and I also have an HDMI 3 & 4 and DVI 2 but there are no codes for them.

Have you had any luck in getting the full discrete set for the 73833? I have one set for delivery in a week and a half and want to get the base programming for my MX-950 done.

I have all codes for the 73833 except the HDMI 3 & 4 and DVI 2 in rcc (MX-3000 or mxa (MX-950) if you need them. Also I did not do the play, ff, rewind or any of the tape functions. Just the TV functions but I do have the main discretes for the inputs and on-off done.

Has anyone with a Mitsubishi xx833 or similar found a discrete code for Speakers On-Off? It's an option only available in the Audio Menu when something is plugged into the digital audio out plug. Thanks!

A bit off-topic, but possibly useful to others, the same procedure works for the newer WD-xx835 series with slightly different results:

INPUT followed by 1 - INPUT-1
INPUT followed by 2 - INPUT-3
INPUT followed by 3 - INPUT-4
INPUT followed by 4 - HDMI 2
INPUT followed by 5 - INPUT-1
INPUT followed by 6 - INPUT-2
INPUT followed by 7 - INPUT-4
INPUT followed by 8 - ANT 2
INPUT followed by 9 - ANT 1
INPUT followed by F1 - HDMI 1
INPUT followed by F2 - HDMI 2
INPUT followed by F3 - HDMI 3
INPUT followed by F4 - HDMI 4

Otherwise, everything else is the same as described above.

Now if I can only get the rear IR input to work well with my Crestron system, all will be well.
