I'm facing a problem of the LCD fading out then it will reset itself, even after changing the battery. Anybody knows what is the cause of problem and how to fix it? It's a Pendulum v5.50

Hello

Well, when I was dismantling the pendulum, I got a lazy man idea, why don't I cut small pieces of paper and stack them together below the battery cap? And guess what, it worked (I did a shake-test at the level of a mad man ).

The problem is, during that process the old soldered speaker wire came off Well that shouldn't be much of a hassle, I can just re-solder it back.

Anyway, I will upload later the picture of the PCB, maybe you all can figure out for a more 'elegant' fix for the fading-->reset problem Just telling you first that it will be taken by HP camera

On top of that, when I bought this pendulum (used of course), the only viewable angle is low, if I view 90 degrees I wouldn't see anything, but it becomes clearer as I lower the angle of viewing. I tried swapping the LCD with an old Digimon version1, but it was not working. Any idea?

Well I totally forgot about the possibility of the PCB being dirty, maybe I can clean it later and possibly add a thin layer of sponge to make the LCD position 'tight'

Yeah, the display became messed up, obviously not the same type or specs of LCD, just wanted to try my luck
