Maybe there is a problem with your 7809 regulator.
Do you use a tantalum capacitor or just an electrolytic capacitor at C2? If just an electrolytic capacitor, try to add a 100nF capacitor in parallel to it. You can solder it in the underside of the board.

For long term use it's not recommended keep it powered by just USB, especially if you have the TX module attached, to broadcast info to Wireless Display units.
