Hello.
I'm a new registered user. I've started my collection of G&Ws and own 11 of them up to today. One of the things I do, when I get a new G&W is to deep clean it to put in my display at home. I've noticed tha in some games (let's say Lifeboat) with brand new batteries the sprites have low contrast, while in others (like Fire) are deep black I'm gonna replace the polarized screen soon to see if helps.. but my question is:

if I replace the capacitor, will the contrast gain something?

I did the capacitors replacement on GameGear to fix the screen contrast and wanted to know if this tip can work even for G&W. Or is there any other solution I can take to enhance the contrast?

Thank you
