System 11b display PCB?

[Angry_Radish]

Looking at my first SS pin, a Cyclone (Thanks again Brian!), the P3 and P4 displays were changed at some point and evidently they used a hot butter knife as a soldering iron, resulting in lifted traces, missing pads, short leads, etc..

Before I turn this thing into jumper-land with lots of wire, I had a question..
I see I can buy entire replacement display boards or even new LED replacements, but what about broken PCB's? Do these things come up often?
It would save me a bunch of repairs and a nasty looking board if I can source a bad PCB with intact traces but I don't know how common these are.
Is it worth holding out?

Cheers!

So I got bored tonight and decided to have a go at this PCB, jumpers everywhere!

The lower displays are fine (though not laying down flat, leads to short), but the top left display has a flickering issue.
The leftmost digit flickers, but not always the same one. It's always the leftmost active segment, not the same every time.

Would this be indicative of low voltage? Bad ground to the display?

See the linked video, my apologies for the sound, my digital camera doesn't let me disable audio when recording and I'm to lazy to re-encode.
