Hello,
I ordered the K8098 Audio Analyser kit and assembled it with great care. After applying power (12V and GND) to the device it will only light the LCD. There is no text on the screen and I can not find the problem. I was very careful to measure every resistor and cap before installing and have check to installation errors as much as possible (looking for shorts, cap installed wrong, etc.) and everything checks out. I get about 3.24V out of the voltage regulator and see the expected voltages everywhere I can check on the board.
I do have picture of the finished board but need to know where to send them for verification. Please let me know an email address that should be used to receive the pictures or get some additional help.
I would like to purchase some more boards but really need to get the first one to work !
Thanks,
David D
