Megatouch XL - No Video

(1/3) > >>

BadMouth:
Megatouch XL with Gold Key running Platinum off an SD card.
I'll dig it out of storage and post mobo specs this evening.
Monitor has been replaced with an ELO LCD serial touchscreen.

This used to be an intermittent issue.  I turn the machine on and there is no signal going to the monitor.
It used to work after restarting it a few times, but now it never comes up.

ed12 recommended trying it with the original Megatouch Gold CD in case the video drivers are messed up.
I haven't tried that yet, but will this evening.
I would think something would be sent to the monitor on startup though, a bios screen or blank screen.

Things I have tried:
Different monitor.
Reflowed the solder on the VGA connector on the mobo.
Tried a different I/O card.

ed12:
a few fast q's are in order here
i/o card ? as in the interface to the control's?
or as an interface to the monitor ?
the mother board should have a sep  vga video out
if it dose revert back to it,remove any video card u have added
then u should see post bios
ie ram chk/hr-drive/cd-rom boot order etc
get back to us

The smaller daughter board that sits above the mobo and connects via a riser.
It contains the audio and key.  It might not have anything to do with the video, but I had another one, so I swapped them to see if it made any difference.

The monitor is connected to the mobo.
I see nothing.  No post, no bios, nothing.
The monitor says "no signal" as if nothing is hooked up.
The lights on the IDE to SD card adapter blink like something is going on.
(I have a second machine with the same exact setup.  I guess I could power both on at the same time and compare the blinking to see if they are the same)

just no picture.
same as it would be if I didn't have the vga cable connected at all.

The monitor and cable that are in my megatouch cabinet work fine when hooked up to my laptop.

ed12:
ya
the reson i asked for spe'c on the i/o is alot of ppl get a video card confused with that card
u are correct the i/o is a machine interface card,control button's/key/dip switch's

ok set #2
put in a video card that has on-board rom
this way the mobo will c it from boot

also do u hear it beep ??
if so only once or multi time's  ?

BadMouth:
I lied.   :-[

I thought I had reflowed the solder on the VGA connector, but it must have been on the other machine.
Did that and now have a video signal.
(also reseated the processor, guess that could have also been it)

It's hanging at the Titanium loading screen, but I'll get it worked out.
If not, I have a place to ask for help.  :cheers:
