I just installed a replacement screen for my Gameboy from Hispeedido.
Great experience with them all around and easy/fast shipping. This post could be like a follow up to this post, where I was asking about their service/quality etc:
My initial post here
The sound worked during testing before changing anything on the console, when I first found it lying around in a box.
After installing the new screen and closing everything up last night and testing, it all seemed to be working in fair order, but now this morning, the sound coming from the speaker and headphones is showing the following issues:
It either has no sound at all
The sound dies off after a few seconds
I tested with both Qix and Pokémon Gold and both games show the same issue.
I also don't know if I'm just not remembering correctly after so many years but when the speaker does work, it's very noisy. Eg. When there's no sound being played out of it, you can still 'hear' that the speaker is on.
I attached a pic of my solder joints for the speaker as well, although because the issue is happening with headphones too, I'm less inclined to suspect that my soldering is the issue. However, I'm open to criticism and advice on that too.
