Between Chris and Reginald, a little information on just about every general field in electronics is available to you. Most anything that can’t be answered up front can be found out. Sharing information is not a charged service. Feel free to visit and pick our brains.
Basic issues with electronics devices can be analyzed. If there’s nothing we can do, we won’t bill you for asking. We charge $10 for simple fixes, and trickier fixes cost the price of whatever parts are used and $30 per hour of labor. For especially obscure fixes, labor can be outsourced. Our prices there are still very competitive.
It’s simple. If you don’t know: ask.
