I have a GF9797 radio that works only once in a blue moon.
When you press power button the display screen won't show any digits, sometimes it shows partial numbers. If you press it again it will go for clock selection, or part of a FM frequency display. But once in a while it starts scanning like usual and can auto scan and select a station.
Repeatedly by pressing the power on button if it is not working, if you unplug and lug it back after a min or two it might work normally in radio mode.
I cleaned all the switch contacts and this didn't help a bit. Cleaned the AC in plug/battery switch and showed no difference.
What is causing this issue? Any help regarding this issue greatly appreciated.
