Hi all!
I got an Omron NT600M-DT122 to fix. I starts up now somehow, but I do not get any text on screen. AFAIK I should get _something_ when the battery has been disconnected, some kind of optional menu. The first problem was by some reason a resistor between reset (7705 output) and +5V, then I got some life to the data and address lines. Next, I wanted it stable, and I have to fix the EPROM socket. When that was done, it starts up "properly", the Run led is on when resseting, the battery flashes for a short while, backlight comes on, then nothing more happens. Any ideas anyone? BR Sonnich |
