I recently purchased an LK204-25WB, and am quite pleased with it. However, after playing with it successfully a few times, it suddenly and inexplicably doesn't work. I can't even get it to power up. I've made all the proper connections, and have a power supply with proper voltage and sufficient current.
It's possible that I'm overlooking something, but I think I'm dealing with a dead display. I've had it hooked up and working before, and I don't think I'm doing anything differently now that would make it not work.
I haven't noticed any smells or heat on any of the chips, the thing is just dead, no flicker, or anything.
Any ideas?

Hello...

Do you happen to have a multimeter handy...?

Sure, I've got a multimeter. What do I need to check?

What is your input voltage?

input voltage is 5.05 V, steady.

also, total current to the display starts at 55 mA when you power it up, but slowly drops to about 52 mA.

So something's using current...

What is the voltage of pin#2 of the strip header connecting the PCB with the display? On the display size it will have the pinout...

for that header, voltages are as follows:
PIN : VOLTAGE
===========
1: GND
2: 5.0 V
3: 3.3 V
4: 3.0 V
5: 3.2 V
6: 3.0 V
7: 3.1 V
8: 3.1 V
9: 3.3 V
10: 3.1 V
11: 3.4 V
12: 3.4 V
13: 3.4 V
14: 3.5 V
15: 5.0 V
16: 3.0 V

Can you email me at myero@matrixorbital.com and we can discuss RMA options...
