Repairing a non functional Fusion 8HD

Hi, I am repairing a non functional Fusion 8HD, below is what I have done so far.

I found a broken circuit board on the pitch bend wheel ( I ordered the Pitch Modulation Assembly from Akai Parts for $14), 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. I now have a blank blue screen on the Fusion.

Still no luck with the broken Fusion, I tried switching out the old power supply with a new one - no change

The display dimmer has no effect on the display so I replaced the old dimmer circuit board with a new one,
still no change.

I turned on my working Fusion, when the dimmer switch is turned all the way up I get a blank blue screen like on the broken Fusion

When I turn the dimmer switch down on my working Fusion I can read the text, so I believe the problem may be in the dimmer circuitry (hopefully)

No audio from the headphone jack or main output

I disconnected the inverter pc board to see if any text would show up on the display, no good

I reconnected the inverter pc board and turned power back on and there was a brief display of vertical lines on the left side of the screen

Any thoughts about what the problem might be would be appreciated.

Thanks ...Jesse

I received the Fusion Pitch & Mod wheel assembly (part # TWPITCH/MOD), waiting for the LCD/LED back light screen to show up. If I don't have a working LCD screen after replacing the LCD screen, I will order the right front PCB Panel Assembly that the LCD screen is connected to (part # 9-79-0308-A about $86)

It appears that the product lines listed below are coming under the name INMUSIC http://www.inmusicsales.com/products ION Audio
Numark
Alesis
Akai Pro
Mixmeister
Alto Professional
SONiVOX
M-Audio

I received the 240x128 graphic LCD display with 5 volt LED back light, I will probably change it to a 12 volt LED to make use of the dimmer PCB power source. Moving on to the next phase. Install new Pitch/Mod assembly and LCD display.

Stay Tuned to a Forum near you for the results as time and money allow me to continue.

Note that the Fusion LCD and the Hantronix HDM 128GS24 both have the same 240x128 graphics display and use the same Toshiba T6963C display controller (see attached PDF file)

I tested pin 3 from the LCD output of the Front Right PCB with the fusion turned on and it measured -11.5 volts.

The pin outs appear to be the same, if anyone notices any differences (see attached PDF file) please let me know.
I connected the Hantronix HDM 128GS24 LCD display to the Fusion and it had the same blank display as the original Fusion LCD display.

I have ordered the right front PCB, part 9-79-308-A, hopefully this will enable the LCD display (and some LEDS that are out) to function properly.

Once the LCD display is working I can start experimenting with different drives and memory devices for storage.

Wow that's a lot of work Jesse! Any idea what the costs are so far? Also had it been dropped or had something fall on it to cause the damage or was it just doa?

Thanks for all the info. This is the sort of thing that keeps great synths alive :)

I bought it used from a guy who moved and some where in transit it went from working to not working.
Also he had opened the case to replace a defective Input/output PCB 9-79-0313-A

So far I have spent about $130 for parts + S&H
$14 for the Pitch Modulation Assembly (part # TWPITCH/MOD) from Akai Parts, Numark (now In Music)

$20 for the Hantronix LCD display HDM128GS24
http://www.mpja.com/LCD-Display-240-X-1 ... 003%20OP/#

$92 for the Right Front PCB 9-79-308-A from Akai Parts, Numark (now In Music)

I contacted Alesis Service Center TSI in NJ, they estimated $186 to repair it based on the information I gave them, I still may end up sending it to them, but I am hoping to resolve the problems myself so other Fusion users will have more information to help them do the work themselves.

Well I received the Right Front PCB, only problem might be that I ordered 9-79-0308-A and I received part 9-40-0308-A?

Well I'm no electronics expert Jesse but they look very different to me? Maybe the connectors will fit but will it work?

Hmm.

The silkscreen printing CLAIMS its for the S80 Right pcb etc, but I wonder about the difference between the 40 and the 79 in the S/No.

Curious, is it not, to do a revision on a legacy board . . . . if that's what it is . . . ?

OR DOES IT FIT AN AKAI PRODUCT TOO???

Are all the mounting holes in the "Right Place"?

They should have explained the SIGNIFICANCE of the S/No difference . . . IMO

Perhaps they can be asked?

I called Numark/InMusic and there was no explanation for the difference in the listed part number and the part number printed on the PCB.

I am getting ready to check it out and see if this fixes my problem. :?:

Oh dear!

NOT a satisfactory answer to a technical inquiry to a "technical" department. Makes you believe they just have someone who answers the phone.

Makes you wish you'd said "No, I don't want to speak to the manager, I want to speak to the guy who knows whats going on!"
:/:

The silk screening suggests to me that it IS in fact, the right part, Jesse - so all should be well . . .

(fingers crossed)

Regarding the display: did you take a closer look here:

http://www.newhavendisplay.com/lcd-grap ... 1_105.html

Most of these displays stated: Controller: RA6963 which seems to be an equvivalent to the Toshiba T6963 controller (the RA6963 is also used with the NHD-24064WG-ATMI-VZ# which is our 'Cool Blue').

Maybe one of those 240x128 displays can be used as a replacement for a defective Alesis display? Just a thought...

I'd say it stands a good chance especially if the physical form and fit is good and the connectors look the same - I maintain my own Jaguars and portions of the part numbers change with alarming frequency over the years as improvements are made and spare parts sources change. The parts guys will look it up for you and only see the superseded part number so probably wouldn't know. Good luck to you (and a very Happy New Year to you and yours and to all here at Yamaha Forums).

Well after installing the new Right Front PCB I still have a blank screen on both the original and replacement Hantronix LCD.

I don't think the LCD display is the issue, I think the display may not be receiving the data input it needs.

It appears the Right Front PCB is just a relay between the Main board PCB to the LCD. :(

I will contact Alesis and one or more service centers in an attempt to determine if this is true and to find out what component(s) on the main board might be the culprit ???

Stay tuned I will continue with this project as time and money allow.

Alesis if you are around Please help me with this! Thanks 8-)

Thanks for the additional information Miks

The Hantronix LCD display is the same size and configuration as the Fusion display and utilizes the Toshiba T6963 controller chip and only cost $20 + S&H

Oohh... ok... that's much cheaper 8O - thanks for that info. Can you name a source where to buy the Hantronix display (just in case that someone should be in need of one...)? :wink:
