Didn't realize replacing just the backlight was an option. Have since bought [3!] new screens at $20 each. I'm about to open it up. I think I'll pass on the SSD drive, as the guy at Micro said that it won't be any faster. He recommended buying a faster HD for speed purposes. Do you find a noticeable difference in time loading sounds?

Hi <billmelator>,
I've yet to have problems with the display so far, but as far as the SSD is concerned, I personally didn't see any improvement in operational speed.
It is of course, quiet - which helps, if studio-bound. The Fusion will be more robust to damage if you are gigging - which is a big plus if this is what you do . . .
The SSD is also kinder to the PSU with respect to power consumption - which also has the knock-on effect of running cooler too . . .
The data-transfer rate is, I think constrained by the legacy IDE internals - so any higher HD/SSD performance is negated by this . . . .
Best Regards

Come the middle of November I will have a few days to work on my non working Fusion 8HD again, I will be removing the motherboard and checking for any cracks and/or bad solder joints. I contacted TSI to see if they could test and repair the main PCB, but all they would do is replace the main PCB with a new one if available, very disappointing, I can do that myself I might temporarily replace the main PCB with the one from my working 8HD if I can not determine the problem and repair it on my non working main PCB to confirm that is the problem. I will keep you updated. I think I need to get some training on replacing surface mount solder components.

Hi Jesse -
That's tough . . . . .
What's the status of the HD on the non-functioning 8HD? Presumably, its a clone of the Working one's HD?
(just a thought, so you KNOW that it HAS something to display if it suddenly decides to work . . . . )
Sure hope the pcb inspection reveals something REALLY obvious . . .
From your comments about the seriously YANKED ribbon cable - perhaps look closely at the ribbon SOCKET(S) on the motherboard for compromised soldering of the socket?
good luck!
A new pcb is gonna be really expensive from what I've seen . . . perhaps a SUITABLE spares or repair THIRD Fusion even?
The mobo IS identical between to 6/8HD? (and therefore interchangeable) . . . ?

Hi Jesse - That's tough . . . . . What's the status of the HD on the non-functioning 8HD? The HD is in good working order with the basic sound banks Presumably, its a clone of the Working one's HD? (just a thought, so you KNOW that it HAS something to display if it suddenly decides to work . . . . ) Sure hope the pcb inspection reveals something REALLY obvious . . . From your comments about the seriously YANKED ribbon cable - perhaps look closely at the ribbon SOCKET(S) on the motherboard for compromised soldering of the socket? That's the first area I plan to check. Seems like practically no one repairs circuit boards anymore but I will give it a shot because I like a challenge

Take Care ... Jesse

Alesis Fusion affectionately known as "The Beast" I will have to try this (put a jumper on pins 5&6 of a WD SATA II drive to reduce data speed to that of a WD SATA I drive) on my working Fusion 8HD on the external SATA port and with the internal IDE/PATA connection using an IDE/PATA to SATA connector SATA-2 hard drives are backwards compatible with SATA-1 controllers. The same is also true with SATA-2 controllers and SATA-1 drives. However, if you have any difficulty with drive detection using a SATA-2 drive on a SATA-1 controller, install a jumper across pins 5-6 (at least on WD HD drives) to limit the drive to SATA-1 speeds.

That's an interesting proposition Jesse . . .
I look forwards to hear what you find

Alesis Fusion affectionately known as "The Beast" Well today I finally got around to replacing the Main PCB with a used one I bought a while back ... It's up and running. I updated the OS to 1.24 now I just need to run the diagnostics I now have three working Alesis Fusion 8HD's

Wow this is long ago. I did get it to work, and it's served me well ever since. Now though while repairing a couple of springs, upon reassembly, the keys don't work. It powers up normally. The sequences play, but hitting keys does nothing. The cables look fine. Any ideas?

Alesis Fusion affectionately known as "The Beast" Did you check all the wires from the keyboard to the Fusion? A loose or disconnected wire/cable could be your problem
