Yamaha Tyros 2 Stuck on "Initializing regist backup"

[Terrum]

Hi, I got myself a non-working Yamaha Tyros 2 today.

When powering on, it says 'Force Format Mode' for about 10 seconds then goes to 'Initializing regist backup' and sticks there, seemingly permanently.

The two caddies I can access are the hard-drive caddy and the DIMM memory caddy. I took the hard-drive out and it didn't help, and the DIMM memory caddy is empty.

Holding down the right-most white key (C6) when powering on does not change anything - it still insists on forcing this 'format mode'. I tried a different power cable and a different hard-drive just incase that would give it a push in some way, but to no avail.

However, when trying to access the 'Test Program' (by pressing C#2, F2 and G#2 on power up) there is an error:

"Unexpected error! Turn the power off and on again. hisysdwn.c/110 8C5DDFCC/25110342-147"

I already tried upgrading the firmware to the latest (1.31) however this did not solve it.

Can anyone offer some assistance on what I should do to diagnose it? I can open it up and put a multimeter onto points if required.

Many thanks for reading and any help is greatly appreciated!

Terrum,

Chris usually answers quickly if he is around. Maybe he is on holiday.

Terrum,

Chris's nickname in the forum is overover. He was last active at 2:00 PM today. He must have missed the post or is thinking. He is very knowledgeable and may have an answer for you. I would private message him.

You confuse me when you say Dimms memory caddy. As I remember you just flipped the keyboard and removed the cover and Dimms slotted into spaces provided. If I were you I would ring Yamaha service department and let them know what is happening and they will advise.

Sorry for the confusion. You are correct by that I flipped the keyboard and removed the cover, however the DIMM slots are empty. This was just more of a confirmation than anything as I know they are optional. I have already sent a 'fixing & servicing' enquiry a few days ago and waiting for a response back from them
