My Hisense AP-05CR1SUVS will not turn on. I've done the reset and test button on the power cord that is working fine (green light on. However the A/cC unit does not power up. none of the control panel buttons activate no lights,etc. before that when i tried to turn on it would go through all the options and then turn off I could not control it . now it does nothing? Is there some reset trick? I've tried to find a manual but all the sights seem to be wanting me to buy something
