Just got back from the store. Sorry I'm very new to this. What should I measure and how?

No but I can go after work and get a fairly cheap one. It will probably come in handy for other uses.

Yes, the backlight is already on when I first start the unit.

Hi,

I brought this issue up on the lcdc boards first but it seems to be more a hardware problem more than a software one.

I set up hotkeys via lcdc but can't seem to toggle the backlight on/off with it. I also tried the AlphaDemo and the program couldn't toggle the lcd backlight either. Everything ...

Done.

I would just like to thank you for all your help and patience. I would like to add that the support given by Matrix Orbital is top notch and unparallled. I myself appreciate such support and dedication displayed by Henry and his team. Thoroughly enjoyed doing business with you and would ...

Unfortunately, that did not work but I did get a character when the lcdc started "||". Sending text or turning on/off the backlight with lcdc and alpha did not work. Can I send it in to get it repaired? If so, approximately how long would it take or would I just have to purchase a new one? When I ...

I'm fairly new at this but I can make an attempt at it. Just solder that missing piece?

No my power supply and serial cable host are plugged into the same wall socket. Forgive my ignorance but I'm not sure what you mean by grounds. Should I have grounded the lcd? If so, what would be the best way to go about this?

Henry, I emailed you with pics of the LCD. Please advise to what I can do in order to repair this problem.

Ok. I did all of the above. I still think I some how fried the path from the RS232 and Power Connector path on the PCB. Is there any other way to bypass the serial connection and still communicate with the LCD? There seems to be a small section of copper missing from the path. Can I just put a small ...

I can barely see it but it is there and blinking but the problem is that I can't get any program to communicate with the LCD itself. The program says its communicate and sending fine but no commands or text is displayed on the actual LCD.

I uninstalled and reinstalled everything and still nothing would communicate with the lcd. Then I examined the board and I think I found the problem. I'm new to this so please bear with me. On the pcb, the path that connects the RS232 and Power/I2C connect seems to have burnt out and part of what ...

Ok. I tried AlphaDemo and still nothing. It definitely is a straight thru serial cable. I have the blinking cursor but you can barely see it. I don't know if its the contrast or not. Also nothing would work (sending text or turning on/off backlight) with either the AlphaDemo or LCDC. Should I ...

Hi,

I'm having trouble with my LK204-25-WB-V. I modified the floppy power according to the instructions connected the LCD via a DB9 male to DB9 female straight thru serial cable. Downloaded and configured LCDC. The LCD actually powers up fine with the blinking cursor but will not display anything ...
