Hello , i just got a Kenwood TK-760G , and initialy it had a problem , all characters from the lcd light up , after that i had re made some contacts with solder , and now its working but it shows on screen UNPROG , and it only responds to ON/OFF switch , initialy if i leave the unit off for couple of hours it will show up " PROG 576 " after that if i turn it off then on again it shows UNPROG , and its responding only to ON / OFF switch , nothing else .
