Alpine CDA 9886 problem



Hi guys, I’m having a small problem with my stereo. Whenever I press any button the whole power on the unit goes blank and comes on, it’s happening intermittently. It’s been installed for a year now and it was fine before. It just suddenly happening. As if it doesn’t have enough power, like a light bulb going off, it’s only happening when I press any button on the radio.

Thanks much.
