After the usual devastating discovery that my new monster 47" Toshiba has none of the usual source or power discrete codes I spent hours searching likely "spare" codes but with no luck so far.

I will upload a copy of the listing of known codes for this big new LCD screen in case anyone is having problems learning codes. The screen is great, the codes are a real pain.

I found the best learning technique is to put the remote and the iPronto about 4 inches apart , start learning, press the button for just 3 seconds and release. Don't wait for the iPronto to confirm learning; it will do so after you release. The buttons mostly learn first time but do need checking as 1 in 10 learned a bad code.

Codes are very short - typically 900A 006D 0000 0001 40BF 00FF (code for button "0")

With no discrete power on, use "0" to guarantee power on, and "0" + Power toggle to turn off.
When watching, "0" always seems to put the TV into DTV (terrestrial digital freeview) mode. the source button then goes back to the last selected external source. Other forum hints on source selection for othet Toshiba TVs don't work on this one.

Any other new Toshiba LCD users out there, having any more insights?

You understand the system enough to know what all the spare codes are? (Otherwise, see below)

Be aware that Toshiba is the brand with the most reports of serious damage to TV's from testing IR codes that weren't on the original remote. So far as I know, most of those reports were several years ago. I hope Toshiba figured out they had a problem in that area and fixed it and new models aren't as easy to damage that way. I hope that, but I have no information that it is true.

If I had a new Toshiba TV, I would not test unknown commands, even though I did test all 256 commands without harm on my old Toshiba TV (before I knew better) and I continue to test all 256 commands on almost all IR controlled devices I buy of other brands and types.


"Typically"? Or always?
I would expect they all start 900A 006D 0000 0001 40BF then they have the two hex digit command number (00 through FF) and the two hex digit check byte (such that command plus check is always FF).


I wish that worked on my old Toshiba TV (which uses this same basic set of IR signals and has no discretes).

I am canny enough not to just test codes blindly! I only looked for holes in the existing sequences of good commands.
On the "Toshiba 23HL85 TV" thread the Robman kindly gave a full list, but for another TV. This shows that certain command ranges are definitely to be left well alone.
And yes as you say, the IR format is always in the 900A 006D 0000 0001 40BF xxxx format.
Such a shame Tosh get this simple thing so wrong. Otherwise, an awesome piece of kit.
