Topic: Dead 1.0 where to go from here

Today, after months of happy printing and no unresolvable issues everything went to Heck with my davinci 1.0.
CLicking issues after about 3mm of print height prompted me to disassemble the head and clean thoroughly the filament path.

I got one good trouble -free small print out of it and suddenly the lights went out and it would no longer respond.

I have three red diagnostic lights on the board, no internal illumination LED's no illumination on the display and two black lines across the display. It was suggested on one thread that the firmware may be corrupted. I started to do the down-rev/reflash but in the instructions, I couldn't complete the preliminary stages because there is no LCD light at all to verify the flash will work. Maybe I'm reading the instructions wrong , but it seems I'm at a stop because I can't really diagnose further without firmware. Buttons don't respond in any way and I'm at a loss where to go from here.

The board is the older one with the SD card on the front. There is no R271 on it as has been suggested may have failed. During a couple of many many power cycles the internal illumination led's flashed at about once a second with an accompanying 1 second (or so) beep repeating every three or so seconds. It has stopped doing this now and just powers on the board with a slow  running of the PS fan and no other activity.

Any help is most appreciated. I'm using the original xyz software with an XYZero cart and typically print in ABS.

Joe

I do not know if this applies to you 1.0, as this is written for a 1.0A, but check this thread out to see if it applies.  http://www.soliforum.com/topic/15573/j4 … 12v-issue/

Good luck

Re: Dead 1.0 where to go from here

I think his problem was no 5V. I have all three voltages and LED's lit ...just no LCD backlight or any Interior lighting LED's or any other response from the machine. Two black bars on display. It's a doorstop and I can't figure out how to re-install the firmware as the instructions assume you've got an LCD light.
