Re: New Members - please post your introductions here
After having read posts on this site over the years, decided to join in order to access the attachments with the hope to uncover/unravel the illusive and never seemingly lack of component datasheets and board schematics. I refuse to give into the board swap mentality and will make every effort to diagnose down to the component level. Have spent night and day (hence user name lunaysol) researching/troubleshooting to little avail and hopefully this avenue will render better results. Really admire the knowledge/insight of your members and with that - thanks for sites such as this !!!Comment

Hello guys, my name is Zac. Heard about this place from Learn Electronics Repair on YouTube. Trying to become good at board repair, I've been doing this about a year now and have fixed lots of boards. Still a beginner though so hope to learn lots from you guys. I'm from the UK and live in Lancashire.Comment
