I recently purchased an Airsoft Sterling blaster off eBay for $50. The fine print stated has been converted with speaker, battery, led lights, sound board w/micro sd card. Since they weren't the original owners they stated they couldn't get the electronics to work. I sent it in to an electronics store to have a burnt out capacitor replaced. Well it's still not working. Can anyone recognize what type of board this is so I can replace it with a similar one. Thanks in advance. Have a good one take care and be safe.
