sounds like an open soldering connection to me. So that one of the sync signals is not passed to the LCD.

good luck!

did you check the 32.768kHz crystal oscillator? some people reported problems with the crystal.
can you check the reset circuit?

[EEngo]

yes, I think you are correct.
the most probable (and definite!) cause for a dead CPU is using the wrong power cable. I don't think there is a second...

@paulflan79: Unfortunately, I cannot send you a pm
I could send you an arduino board with the software programmed into already.

unfortunately, I haven't found the connector yet

It would be very interesting when you tell us your experiences with your expansion

I recommend looking for the complete schematics. Because there were no programmable parts used in the ADC or DAC section, in addition to the part datasheets...

Hi!

for a start, you could use the following code and route an I2S Signal from one of the CH1-16 to the expansion slot you are simulating....

Hi!

unfortunately, your main CPU will be killed by using the wrong power supply cable. If I remeber correctly, with swapping the cables, you...

I replaced the CPU chip. There was/is? a an ebay store which sells exactly the chip type needed (ELAN SC300-SC). I used a hot air station to remove and a...

Hi!

I had the same problem on the LCD (missing faders) after replacing the CPU (AM386SC300). Device reset solved the problem in my case.

perhaps this is of help for someone:

after replacing the CPU my board is running again.

with 3V3 and 5V plus LCD the board...

sorry, I found another datasheet which says, all inputs are 5V capable. so it's allright....

Hi there,

I have also a non-booting DDX3216 CPU-Board.
Could someone confirm, that the board should at least show the init screen on the...
