Hello,

I recently puchased a malfunction TEX 61 that looks to have been very well cared for and seen little use. It's mint both out- and inside but doesn't work obviously...

Here is the issues I have located:
- It boots up and have OS 1.0.5 and everything seems to work looking at the screen and lighted buttons
- Only the COMBI and PROG buttons work to the left of the screen (+ the realtime controls seem to work)
- To the right of the screen only the numeric 1 + 2 buttons work
- Only the bank buttons C + J work (but I can access all banks from the touch screen and it looks like all the programs and combis work)
- Last but not least, of the keys only the lower C work + all the G#, A# and C# across the entire keybed

I have tried to get into the diagnostic mode (Enter+5 at power up) but unable to do since the buttons isn't responsive.
Have also measured the power supply board (found instructions in a different topic here) and this looks to be working as it should.

I suspect it previously have had the full RAM + EXB MOSS board upgrade installed but by removing these it shouldn't afftect the basic operation of the keyboard?

Does anyone have ideas of what might be the issue(s) here and possible how to get it sorted?
Any ideas will be highly appreciated.

Thank you and Merry Christmas!

Lars
