If this is a new RIO (under one year, I believe) you can call in and take out a warranty on the part and receive a new one for no cost. If its older you may need to purchase a new one. Hope this helps.

Usually a severe hit is indication of metallic debris being knocked loose, not a component being knocked off. The conformal coating this year should dramatically improve immunity to this issue. Regarding warranty, FIRST has a 3-year warranty on parts, which includes advance replacement during the build season.
Also the note about the buzz is accurate. If it isn't turning on but there is a buzz, that's the power supply trying to turn on, but failing because voltage is too low. The switching frequency is in low enough that it creates a buzz. Always check your input voltage (and charge your batteries!) |
