Help!!! LK202-24-USB

Ok... Here is the full history of what I have done to try and get this display to work. Any help is greatly appreciated!

I just recently got this display 2nd hand. No software cd/cables/etc... I found the drivers after searching this forum. Found the USB drivers, installed them and the OS recognizes it. I downloaded the Universal LCD Software, and it couldnt find the display.

After searching these forums again, I discoverd the changing of types on the LK202-24-USB in the LCD DB from the default (0x02 i think) to 0x36. The LCD Tester now communicates w/ the display. Yet I still couldnt do anything with it. I read in these forums to place a jumper on pins 6 & 7, power up the display, then remove the jumper. That will reset the comm speed. I then made sure all the comm settings were set to 19200 (in all progs I used to try and communicate w/ the display and the sys). The LCD Tester was able to communicate with it. I am now able to turn on and off the backlight and turn up and down the contrast. That is it. Cannot put any text or graphs on it. I had tried LCDC and yet I cannot display any text. HyperTerm was config'd correctly (atleast I think it is config'd correctly) and yet it could not communicate w/ it. Just a blank screen.

The display itself looks as if all the character blocks are lit (every pixel turned on) yet I cannot clear them. I do not get a boot logo either.

I have tried looking for the Display Tuner and found links on these forums, but the links are dead.

This is my sys config:
P4 3GHz HT
1GB Dual Channel DDR Memory
WinXP Pro
Display connected thru USB A/B cable to USB 2.0 port Configed on Comm3

Thanks!

Greetings! Sorry it took so long for me to respond, but evenings are the best time for me to respond.

Here are 2 links of the LCD Display Contrast Settings.

Here is the LCD w/ the default contrast settings:

dum de dum de dum. Still waiting for a response.

Couple of my Electrical Engineer friends and I were trying to get this display working and discovered that it is not initializing properly. Is there any way to reset this display? I would like to try the override procedure yet I do not have the Display Tester Program as I do not have the disk. Everywhere I try to download it, all I get is a page can not be displayed message.

This is getting quite aggravating and poor support. Yes, I know it is second hand, but I have seen another post where the person (8balls LK202-24-USB dead? in Hardware Forum) received some help. His problem sounds just like mine.

Thanks

Can you email be at myero@matrixorbital.ca and I'll send you a software program and a memory chip file that will reset the module to factory default settings.

I have sent 2 emails, and yet still nothing.

First email was sent on 03/04/04 and the second on 03/09/04. It is now 03/23/04 and still nothing. I am still waiting for that software program and memory chip file.

I can be emailed at webmaster@wotoni.com.
