I have a Bearcat 600XLT that has no display. The 13.8v power adapter is new.
I hear a hum from the speaker when it is powered on, but no backlight or display. I also feel heat coming from the voltage regulator (marked 7808), Any ideas? I have no schematics, so if you can point me to a likely component it would be much appreciated. I had assumed a bad power diode, but can't identify it. Harryc -- |
