One more question,
Is it ATM630A reset pin anyware on the board? Or should i solder GND directivity to the chip?

Hi,
I managed to read/write flash without pulling reset pin, and i upladed AMT630A.BIN but, with this firmware nothing is displayed. When video signal is not connected screen is black, when it's connected it's brighter that's all.
What do i wrong?
Kris
PS
Maybe attached original firmware will be useful for somebody.

Hi,
I've found the schematics from supplier https://tigermagnetics.com/zip/AMT630_d ... matics.rar. If I remove all Buck convertor IC and peripherals of XL1509 may I give to board 5V ? Image

Hello everyone!

I replaced the TFT display on my monitor
and the image is shifted to the bottom ~ 16 pixels

where in the firmware can this effect be compensated? :beer:
