IT'S WORKING PERFECTLY. I may try that 3.3 voltage thing later. I will. But right now, it works. I'm putting it back together before I break something else. Thanks so much for your help.

OK I've solved that. One cable had become disconnected where I couldn't see it. I got it working again, but still no right output. Tried dicking with the volume pot w no luck. Something I think is unrelated, but perhaps not: When I turn the 8hd on, I get "Cannot find audio directory." After hitting OK, it goes away, and then works Which cable caused the problem, a picture would be good to relate to the error it caused Error Voice engine 2 has failed+ Failed reset handshake #`1 [error code [0x02071002] Have you tried verifying the files on your Fusion hard drive? Good to hear that you got your Fusion working again

A power source (probably better than coming off the PSU) for the 3.3 volts could be from this connector, wires come straight from the PSUGet a 2 wire connector like this link cut the wires so the female connector has about 7 or 8 inches and solder the wires to your power source.
Next cut off the connector that came with the LED back light and slip a couple pieces of heat shrink on the wires from the 5 volt LED backlight so you can slide it over the solder joints after you solder the wires with the male connector to it.

Well today I finally got around to connecting the top half of my non functional Fusion 8HD to the bottom half of my working Fusion 8HD
The top half of my non functional Fusion 8HD appears to be in good shape the LCD display works just fine and everthing else appears to be working, so I will run the Fusion's diagnostics to thoroughly check it out, then move on to the next phase.
This leads me to what I was afraid of in the beginning, the problem appears to be on the main PCB. When I first opened up the non functional Fusion 8HD I found a broken circuit board on the pitch bend wheel (which I replaced) and the 40 wire connector on the main PCB was broken and a third of the wires pulled up, I repaired the cable & connector and reconnected the cable to the main PCB, but that did not fix the problem, but now that I am sure the problem lies with the main PCB I will remove the main PCB and check for bad solder joints where the 40 pin connector is attached to the PCB.
If I am lucky that will be the only problem

I may have broken out the chamgaigne too soon. The right output's not dead any more. After banging on the unit, I'm getting the right side only at about 10% the volume of the left side. While the volume know could use replacing, not sure that's it. I will study the repair manual, and get back to you on this in about 3 years. The wire you asked about on mine that was disconnected went from the right side of the main [largest board to the expansion board above it. I'm not sure I'm using the right terms, but suffice to say it has the biggest connectors and is the shortest wire in the 8hd.

The 9volt thing is quaint though. Thanks

While the volume know could use replacing, not sure that's it. Run the built in Fusion diagnostics (press the "1" & "8" buttons while turning on the Fusion), it may give you a clue to the problem with your audio output I will study the repair manual, and get back to you on this in about 3 years. LOL Hang in there The wire you asked about on mine that was disconnected went from the right side of the main [largest board to the expansion board above it.

I believe you are talking about the 50 wire ribbon cable from the main PCB to the Digital Exspansion PCB
Thanks for the info, it may help someone else in the future
Was the cable completely disconnected or just lose on one side?

Sorry, it's back together until I can plan my next move. For now it's a mono keyboard, I guess. All the screws are different sizes now, as they've been taken out and replaced probably many times by the previous owner.

I connected a 40 pin 80 wire dual drive IDE cable to the Fusion IDE hard drive connection in an attempt to see if we could have a MASTER and Slave drive, but it would only recognize the Master drive. Fusion load times I have that I will run it and a few of the piano's from the Ultimate Piano Collection, which I believe you have also Ultimate Piano Collection - FAZ.DYN.32-11 Samples 37.2 MB Time to load Maxtor 40GB IDE/PATA HD 18.4 seconds (parametric Kingspec 128GB PATA SSD 23.58) (WD1600SB 160GB IDE/PATA HD 16.3 seconds)Ultimate Piano Collection - STWD.DYN 32-11 Samples 35.3 MB Time to load Maxtor 40GB IDE/PATA HD 18.0 seconds (parametric Kingspec 128GB PATA SSD 18.32) (WD1600SB 160GB IDE/PATA HD 15.9 seconds)

Note: Temperatures shown below are the Peak Temperatures observed. The Heat Sink Temperatures cycled between 118.7°F and 123.3°F with no activity on the Fusion, The Fusion was simply Idle.

Sorry to hear that Jesse. My main fusion's screen is starting to blink. A lot. So I just re-read all of the above. Thank God it was all still there, as I couldn't remember what had happened. If and when I fix it, I will expound on it here.

After reading your adventures fixing one, I followed your link and replaced both of my 8hd's screens with your $20 items. Both worked, but I couldn't figure out how to power them off the ciruit board. I conected it directly to a 9 volt battery, and later an adapter, and it works great. Thanks. I'm now thinking about putting in solid state drive, as, during a gig recently, I kicked out the chord and it took 30 seconds to reboot. Any suggestions?

Hi Jessie One of my Fusion 8HDs' screen went out. It seems the 9volt/adapter arrangement failed. The other one's working great and bright, using your $20 screen and an adapter [I may try your patching into the board next time I open it up, but for now, why mess w success? I'm now about to replace the screen w another $20 screen and try your 'patching into the board' solution for powering it. Not sure how a screen that works well with 9 volts 300ma will deal with 3v, but once it's open, [and I have a working spare] I'll try anything. In that same vein, at the same time, I will, if I can figure it out, put in an SSD. Is this the way to go: www.ebay.com/itm/2-5-PATA-IDE-SSD-128GB-for-DELL-D610-9300-D810-HP-V2000-IBM-T43-Alesis-Fusion-/171237136970?&rmvSB=true ? Or how about this: www.cnet.com/products/wd-black-2-dual-drive/ --a combination of HD and SSD? Do I need an adapter? How goes the repair of the non-working 8HD? I may have a spare motherboard for you. If interested, let me know.

I may have a spare motherboard for you. If interested, let me know. By supplying 9 volts to the 5 volt LED backlight, you probably burned out the LED back light not the LCD display, in which case you should be able to replace the LED back light and the display should work fine. I don't know about that brand of SSD, I know Chris & I have used a Kinspec PATA/IDE drive that worked just fine, I would think any PATA/IDE SSD should work just fine with a 128GB SSD being the largest size the fusion will format and use, anything larger will be a waste as the Fusion will only format and use a max of 128 GB of a larger drive. Good luck to you
