BeoMaster 5 motherboard

54 replies
Hello Roland,

Did you «Buy a new cable with a 3 pin connector to connect to the original cable to the ML-PL-module and solder the new cable to the two soldering points of the optical connector on the solder side of the Via motherboard» ?

My system works fine and I hope I don't have to buy a new motherboard anytime soon and even though I find the thought of soldering anything on a motherboard quite daunting, I'm thinking perhaps I should buy this cable now before it becomes difficult to find?

Best,

 
Hello XavierItzmann,

As I remember the cable to connect is a standard 3 pin connector you can get in electronics or computer shops.

I think I unsoldered and used the old cable, but not sure.

I have a similar problem with my beomaster 5. It shows : DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.

I can enter the bios with an external keyboard -> looks like the HDD is faulty. I have to do a fresh installation. Any other suggestions?

Would be great I somebody could help me out with a copy of the service tool.

BTW: will this SSD work?: https://www.ricardo.ch/de/a/ssd-wd-blue-sn570-1228224376/

Hello gebi,

I am not sure if the linked SSD will work, as I can not find the specs to confirm if it has the required Marvell Controller 88SS1074.

You might be able to ask Western Digital customer support about this.

I have installed a WD Blue 3D NAND that has this controller, as reported in these reviews:

It is a little bit more expensive than other drives, including the linked WD Blue, but then you know it will work.

Best regards,

Jens

PS. I have sent you a PM regarding download of the service tool.
