Newbie looking for some advice. I got this LCD game a while ago as a non-working on a fling, and recently I've been studying electronics a bit more and figured I would dig it out.

The first thing I did was remove a ton of corrosion from the battery contacts. That was easy, but then I ran into a new problem where the screen doesn't look right. Elements are lit up or not lit up correctly, etc.

I got to wondering if it wasn't a problem of the connections being weak as I've seen some examples of people fixing LCDs with missing elements by tightening the screws in their frame, for example. Well I opened this one up, and the mainboard looks fucked to me. I've never seen a board come out of a device and look like this before, so my assumption is someone back down the line tried to fuck around with it and fucked up. I'm not sure though. Can anybody give me some advice on how I might address this?

One thought I've had is with the LCD. The way this works is similar to another one I've taken apart; The display sits on top of two long rubbery pieces that contain circuitry, and the rubber is stuck onto the board where the contacts are for the display. I was wondering if I couldn't unseat this, clean off the contacts and the rubber, and reattach it. My concern is that I'll never be able to reattach it properly/it will be loose. The last device I did this on was smaller and screwed together tightly, so it still worked. I don't know that it would work on this one as it is more open and the LCD is not tightly held in place by the casing.

Any insight is greatly appreciated, thanks all.
