My pops has a fairly new within 2-3 years garager door opener. 1/2 horse. The unit will not work, the leds light up but when you push the button, there is just a "click" sound. Motor won't turn. Trying the cheapest option I replaced the capacitor, but same thing. A new board costs almost as much as the opener itself. The light bulbs do not light up when activated. Any thoughts or ideas would be appreciated.
