Oh, my surly lilliput... :mad:

bulgogi777 · 08-10-2004, 10:13 AM

Ok, I'm at the point where all I need is my lilly to function correctly and I'll be at the operational carpc status! Herein lies the problem...

There is only two mods that I have done to the lilliput.

1) short the power button using this method

2) replaced the din

The first time I replaced the din, I used a 9-pin serial, with the sheathing ground in both ends of the cable attached via a separate wire. At this point, I tried my setup, and found that once power was provided, it would keep flashing the "no signal" on and off.

I thought maybe my serial connection was hacking it, so I cut those off and connected both ends directly.. matching color for color and ground still attached via the wire. Gave it power, and the same thing happened, "no signal" flashing on and off!

Can you guys think of anything that could be causing this? Please help! I'm so close to being done, it's killing me!

any thoughts, please?

I'm not sure I understand what your configuration is now but it sounds like you have the VGA pins miswired. Double check your wiring with a meter and verify that it's wired the same as when you bought it. As for wire colors, the color of your original wires and those of your new cable likely have no relationship.

What is that? An 8" screen? I'm not exactly sure what it is you were trying to do there, but I will try to add my input.

When you removed your wires to add the ribbon cable, did you take a picture of the wire order first? This is important because on my 7" Lilliput, the wire colors on my screen and the one on Armen's website were completely different. So if you followed someone elses wiring diagram, it may be incorrect for your screen.

That's about the most help I can offer.

Hey guys, thanx for the replies, I didn't match the colors of the wiring to a new cable. I had basically cut off that 9-pin din connector (both the male and female sides) and wired the wires from one side directly to the other.

Just a thought that popped in head. I'm just making sure, but the ground that goes from the control board... (ie pin 1) turns into that bunch of thin wire that surrounds the core of the cable (which contains the actual signal wires), right?

Also, could it be possible that shorting the power switch is causing the monitor to turn on and off and on and display the "no signal" screen? I don't think that's likely, but just trying to come up with anything...

OK, now I understand what you mean. It's still possible (even likely) that the wire colors do not match up between the two cables. Take your meter out and check which wire goes to which pin of the connectors (the ones you lopped off). Verify that everything is the same.

Dunno. What your describing is the cable shield. This is frequently (but not always) connected to ground in most circuits. Just check the wiring with a meter.

I believe others have done this without getting a power cycle. Essentially your just holding the power button down. There were some reports that this makes the rest of the buttons non-responsive. Be advised that there are also some recent reports that suggest that the newer Lilliputs auto power-on on their own (and/or can be configured to do so w/o modding). In that case, your power switch short could be interfering with this new behavior. If you confirmed that everything is correct with your wiring above, then the easiest thing to do here is to unshort your button and see if your screen comes back to life.

As a rule of thumb, it's best to make only 1 change at a time. That way it's easier to debug when something goes wrong.

hey rando, thanx for the tips~! i finally got it working

the colors in the cable containing the vga and usb end are exactly the same as the colors from the vga controller to the 9 pin din. you'd think they would make them match up... but the bastards had to make it difficult

anyways, used a meter, found the right connections, works like a charm... thanx again!

Cool!
