Re: EMAX II Display Problems ....

2012-02-04 by freddy1771994

Argh ... it worked and though it wasn't necessary I crushed it!... Ok
moaning doesn't help.
Well, I'm no lazy forum member and did a bit of research and found this
by jammie.emma explaining how to mount the new vfd display:

I've added some questions, maybe somebody could answer them so that this
could be an instruction for other EMAX (II) users.

[1) I'm an EMAX II Keyboard User. Is there anything different? ....]

"You need to take out mother board and remove invertor by desoldering it

you need to remove the front display take out the display they just pull
of as
they are not soldered
you need to remove the slide connectors from the the pcb with a solder
pump be
very carefull as the pads are week and to much heat will make them lift

they are in 2 rows of 7 you can leave the ones for the backlight
connection as
there is no connection needed for the back light as there is not one

now you need to wire in 13 cables missing pin 3 26awg cable

now solder pin 1 on pcb

the numbers go

13 14
11 12
09 10
07 08
05 06
03 04
01 02

and on the vfd its

1 2 3 4 5 6 7 8 9 10 11 12 13 14

so solder pin 1 to pin one on vfd

then 2 -2
miss pin 3 -3 as thats the angle and its not used on the vfd as there is
no
angle on the vfd is nc any way

4-4
5-5
6-6
7-7
8-8
9-9
10-10
11-11
12-12
13-13
14-14

leave 1 inch slack of cables so that you can move lcd into place easily

now tape up the soldered holes with insulation tape as vfd is going to
sit over
some of them

place the vfd over 1 set of holes near to the back light

[Maybe that's is just a language problem. I'm not sure where to place
it?]

fit a screw wit hwasher onto vfd from front

place 1 washer and a nut and clap the screw to the vfd place washer up
to nut
place vfd through hole on pcb

allign so vfd is straight and mark the pcb making sure it does not come
into
contact with any traces

now mark pcb and drill with a hss drill bit

now fit the scew and washers and nuts to the vfd and place the vfd
screwws
through both holes and affixe to pcb replace

pcb front panel

fit motherboard

remove psu and replace all caps so that you are fully servicing the
machine
[what are caps and why how serving them (buttons?)]

are you going to make it scsi compatible if so i do a board exchange
scsi for
non scsi board and £100

also do the slim floppy convertors £17

if your not confident in doing the work

i do the vfd labour upgrade for £40

i do the psu refurb for £40

and if you have the scsi upgrade already i do the upgrade for £50"

FINALLY I WOULD BE VERY THANKFUL IF SOMEBODY COULD LIST A WHOLE LIST OF
PARTS.
IF SOMEBODY HAD A PHOTO OF THE FINAL RESULT I GUESS IT WOULD SIMPLIFY
EVERYTHING..

Thank you very much!!!
