PFC Commander used 128x64 matrix Seiko G1216 LCD.
you can buy compatible LCD on E-bay. search key word 128x64 lcd, g1216....
you have to attention lcd size & pin map. 75mmx52.7mm

Hi I just tried this with a display from display tech , unfortunately it is not working . I can see the text slightly , but the left half of the screen is on the right and the right half on the left . According to the diagram that came with it it should work . I tried another display from the same manufacturer but same result , can anyone help me ?

Markus1981

This shows my problem better

Check your lcd's pin map. PFC LCD number 18 Pin is gnd. But your lcd is 5v out. I suggest you cut lcd's pattern that Connected to pin 18.
I hope good result.

Markus1981

Thanks for your reply , but I don't understand . What do you mean by cut LCD pattern ? And what should I connect to pin 18 ? Maybe please share with us your display manufacturer u used .

Jin-74

cut lcd's pattern that Connected to pin 18.
because pin 18 connected to Frame Gnd on PFC Main PCB.

and i used "LG128642-BMDWH6V LCD" check below web site and data sheet.

Markus where did you order from.. just spent a bit searching and cannot find much, if anything...

Thanks

This is the one i ordered it's 11,69 Euro + World wide Delivery 7,02 Euro .
I am waiting for delivery from germany
( i am in south africa )
I will hopefully be able to confirm next week if this display works but its got a
Neotec NT7108 controller (compatible to KS0108 controller which is used on the original PFC screen)
You must not connect pin 18 ( insulate it or grind it off )

RF-STORE.COM Your RF supplier

Samsung KS0108 is a generic display controller found in certain display modules.
The following controllers are known to be compliant to KS0108:

Samsung S6B0108
Samsung S6B0708
Samsung S6B2108
Samsung KS0708
Hitachi HD61202
Neotec NT7108
AX6108

Markus1981

Still waiting for my display to test .
I found two more displays , that should also work
one is black backround with white letters
one is blue backround with white letters

LCD-AG-128064H-BHW W/B-E6

LCD-AG-128064H-DIW W/KK-E6

Will get those end of feb to test .
Has anyone else already tried successful ?

any updates on this? I've been checking some out on ebay and amazon but havent seen to many that match up close to the specs listed on here.

Markus1981

Mine is lost in the post . Collegue brings me one from Germany on the 26th will keep you updated

Markus1981

Tried it tonight with the new screen . Soldere the black and white one in . I could see the pic at an angle , but the background of the screen stayed white instead of black . I think I stuffed up my commander now , tried to unsolder and solder the display again , now it just stays plain white . Gonna have to look for a new commander now

Jin-74

Markus.
Are you adjust Commander's Contrast/Bright Control?
I reduce this value 10/25.
hope this help....

I installed a new lcd but I get a white screen in the center and only see the display in an angle. How do I fix it??

Anyone else able to install a new screen with success? I plan to do this when I re-solder the loose wires on my Commander.

thorin

having some electronics knowledge, I'm 90% sure that the problem in most of these cases is incorrect voltage at the contrast pin.

50% chance that if you add a variable resistor in series with the contrast pin, you might be able to get the contrast right.
