Got my displays back from RunnerPack today, they work great and he did a fantastic job. Super clean solder work man. :) No way I could have pulled that off myself.

He even sent me a set of replacement screws as I had lost mine. Thanks again!

Has anyone figured out what was causing those faint moving black horizontal lines in the display? I've read somewhere that it might be dust on the magnifying lens', so tomorrow (or later today I guess... xD ) I might try cleaning those lens' in one of my backup VB's with that problem. Hopefully, this time I won't forget how to put the thing back together... xD Anyway, I recently picked up a new solderd VB, but it has those damn lines in it's left display... So if it works on my backup, I'll do it on my newly refurbished one, wish me luck! :3

It's usually something on the clear window over the LED bar. Try removing the LED PCB and carefully wiping the window. A quick way to verify is to swap the left and right PCBs... if it follows it, it's gotta be dirty windows.

My main unit that physically is in great condition experiences this every one in awhile and then corrects itself. going to need to have Runnerpak repair it eventually.

Well, I've taken it apart and wiped the window clean and the display is better now, but there are still a couple of those lines left on it. Any idea what could be causing this?

Try swapping the left and right display PCBs, and see if the problem follows them or not. If it is them, then you need to clean them better, or maybe the windows are slightly scratched.

If it doesn't follow the display, then it might be some dust or something on the lenses, mirror, etc. But I've never seen it be anything other than the display PCB windows.

Search appears to be busted right now, only returning results on the last page.

Are "sporadic horizontal lines that are at max red brightness" indicative of a faulty LED cable? If so, looks like I'm buying a longer security bit XD.

I honestly can't tell if it's an issue with some games drawing objects at the wrong time, reading "incorrect" data the cartridge/FlashBoy (particularly acute with Jack Bros sometimes), or a bad ribbon cable.

The lines range from sporadic lines of various lengths at various y-positions, to a nice even horizontal stripes every 8 pixels or so.

Actually, I'm not sure if I'm precise enough to do this soldering without screwing it up... :/

But the LEDs are interchangeable? Meaning if I broke it, I could buy another broken VB and scrap it for the LEDs inside?

Yes, that's almost certainly a bad cable connection.

And yes, you can swap displays from any other VB... but if you're buying a broken VB for the displays, the displays are likely what's broken on it, so you'll still need to repair them first. :-P

Hello guys! I have a glitchy display on my VB.

Do you know if it's fixable this kind of flickering with the methods in this post? Here is a video of my display. Can be a power problem?

Thanks!
