Re: Tyros5 firmware got corrupted

Good day friends, For those who are interested in this complicated issue. I was able to reach out to Yamaha USA. Someone by the name of Paul Morte have been very friendly and helpful in sorting out this issue with me. First of all he sent me the Service Manual for Tyros5 which I really appreciated. ...

Re: Tyros5 firmware got corrupted

Hi everybody, Just providing an update for those who are interested in this issue, similar to Tyros4, the following ICs exist on Tyros5. IC114 Program ROM 256Mb, IC118 Data ROM 512Mb, and IC123 Backup ROM / Hardware ID 64Mb. I was able to find the Service Manual for Tyros5. Based on the boot up flow...

Re: Tyros5 firmware got corrupted

On Tyros 5 motherboard the cFeon 29LV649AB-90TIP IC is a 64MB CMOS chip, which I believe holds the firmware. Therefore, replacing this chip should resolve the issue, I guess. Hi, Looking at the Tyros 4 service manual is likely that the firmware is stored in IC16 / IC 19 and possibly IC23. It is unli...

Re: Tyros5 firmware got corrupted

Thank you for the detailed information. Based on the data sheet information on the Tyros 4 Service Manual, IC16 is a 256M Flash ROM, IC19 is a 512MB Flash ROM and IC23 is also a 64MB Flash ROM. These type of chips are electronically erasable and programmable. I doubt that they're burned out only bec...

Re: Tyros5 firmware got corrupted

You're absolutely right. Thank you! Thanks for the update Heda. I would have thought the test procedure would be the same for the Tyros 5. As far as I know, Yamaha has not altered that since Tyros 1 which uses the same combination. Turn the power on with [C#2], [F2] and [G#2] keys pressed and held. ...

Re: Tyros5 firmware got corrupted

I investigated about all the chips on the board and concluded that the firmware cannot be kept anywhere but in the ROM on cpu since the keyboard doesn't have a CMOS chip. Therefore after going through the Service Manual of Tyros 4 I found out that both keyboards use the very same RENESAS R8A77310D p...

Re: Tyros5 firmware got corrupted

Having your idea in mind, I'd even purchased a new flash drive and downloaded the firmware again. I don't connect the keyboard to computer while trying to run the update from the USB flash. You're right there is no need for having it connect, but unfortunately the keyboard doesn't respond. Thanks fo...

Re: Tyros5 firmware got corrupted

Hi, I was able to find the Service Manual for Tyros 4 not Tyros 5 on the internet. Interestingly enough there is a procedure to test all components of the keyboard which should start by turning on the keyboard while holding down the [C#2], [F] and [G#2] keys all together (C Major Cord), but unfortun...

Heda, someone from Yamaha Music Canada should be contacting you via email. Let me know if that does not happen?

For some reason when respond to you I can't see my message. This is the 3rd or 4th times I'm responding. It's so very kind of you. Thank you so much. I'm going to reach out to Yamaha USA/Australia/UK to figure out which chip/s have to be replaced. With my weak eyes I can't replace them. Finding the ...
