Re: New Members - please post your introductions here

Hello. I'm Gerald and live near Seattle, WA. I've been a Linux systems engineer, DevOps/automation engineer, developer, etc. for a huge chunk of my life and enjoy tinkering with computer hardware.

I've read a few of the Sharp TV posts on this forum and have learned more about the inner works of LCD TVs in general, but am not a pro at electronics and hope to increase my knowledge.

Looking forward to the discussions and wealth of information here. Hopefully, I'll be able to contribute.
