Kenwood TH-D7 HAM radio not work after 15 minutes

My radio is erasing the numbers on the screen after 15 minutes of being turned on,
it works fine until the screen erases and transmits badly until the next day we return with the same behavior,
I want your help, thanks.

Hello Pedregal!

Check the following according to the Service Manual:
-Internal supply voltages
-SMD electrolytic capacitors
-Soldering quality, processor, eeprom LCD area mainly
-If there has not been a RESET on the device yet, try this and reprogram.
I hope I helped.

 Best Regards:  Tony
