acer AL2216W -green column displayed continously

[hitz]

Hi,
it's me again with my little baby :/ Due to the lots of (dis-)assembling the ribbon cable to the button board had a crack. So I soldered 15 wires on the soldering points of the boards to reconnect them properly. After having finished I wanted to test the functionality, plugged in my DVI cable, then the power cord. No picture appeared - I forgot to connect the two ribbon cables to the panel... So I unplugged both cables again and there I made the mistake not to wait for all caps to lose their load. While connecting the left ribbon cable, there was a little blue spark in the right (area of pin 1 to ~3). So I knew I may have screwed it, but I gave it a try after properly connecting it all. The result is a greenish column as you can see on the picture attached. It's best visible when the display shows dark/black, nearly not noticable when it's white. The display works fine apart from that (picture is shown, but with a green 'curtain').
Did I wreck the panel or is there a chance only some small parts are killed, so that replacing them could help?

Any help is appreciated )

Re: acer AL2216W -green column displayed continously

you must be clear for "blue spark in the right (area of pin 1 to ~3)", the pins of the pcb connector or the ribbon? And which side? Here is a similar panel datasheet:

those stupids not even have put indication of name where are the 2 connectors and also named those CN1 both. I think you have connected a 5v "V5A" to signals or 13v "Vin" to "V5A"..

Thanks for your reply. I attached a photo where I marked the spot I saw the spark. So I share your opinion of having connected the Vin to the V5A pin.

As a lack of knowledge I dont know how to go on checking it. What kind of information is being lead to the panel driver (which i guess is the circuit board on the top)? Is it just the order to put column X and line Y in blue or is it more complex? What's the RTD2553VH for?

/e: Okay, I found the datasheet for the RTD2553V, which is the driver IC:
Would there be a high possibility to have killed that IC and not the panel? What would be a way to test it?

can you see any damage to the cable or connector pins/pads - may just need cleaned up.

can you get to both ends of the cable to resistance test individual wires

Re: acer AL2216W -green column displayed continously

That's a good point. There are really some of the conductive pads loosened from the ribbon's plastic. Is it okay to put a minimum amount of superglue under them to fix this?

/e: Answered that question on my own. But that brings me to a new one:

HOW DO YOU KNOW THAT IT'S THE SOURCE OF ALL EVIL?

It's fully back in life (see the new pictures). Thank you so much!

So simple?! well.. ;-J
