I just enherited a job with a Mits 62" DLP.

Yamaha Rec
Motorola 6412 CableBox
LG combo player

I cant get the Digital input (HDMI) commands from the URC database to control the Mits inputs. I tried everycode set..... In fact, one code set for DIG1 actually turned on the SLEEP TIMER.

The component input commands work fine.

Original remote doesnt have discret input selection.

Multiple Input macro isnt stable.

Client was sold as HDMI being superior to component by another comany so making the change to component isnt an option.

Old receiver doesnt upconvert, so one input isnt an option.

Anyone ever sucsesfully troubleshoot this?

If the Mitsu is 2006 or newer try this

Applicable Remote Controls and Televisions
This document applies to the full size 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.

WOW!

This sound like the problem!

Lets hope the client isnt home while I am trying this one.

Wish me luck!

Mits remotes have had this capability since 2000, it's just a slightly different implementation for the older models. See this thread.
