Just found the issue! We checked the voltages of every pin and compaired with yours. Our system showed the same symptoms as yours but in our case it was a "KIA 7808A" 8volt Voltage regulator that has gone bad over the years! After hours of searching and tracing back we found it tucked in on the right side of the "PA Unit". Finally works again thanks to your help! Greetings
Hi , i have the same symptons as your icom 7600 , icom do not supply the board . I am hoping you could help me out please . By any chance could i post you over the board and if u can repair it i can pay you for parts and time . Any help be greatly apprecuated , 73s
@guidoborghesani6208 hi and thank you for reply . My friend is a service technician and he has told me after watching your video the voltages are not present or correct . Icom do not have this board any longer so I dontt know what to do . Thanks
Would you be interested in looking at this board if I can't find anyone here in Ireland. Icom very disappointing as they cannot supply the part . Another suggested that the board suffers from dry solder joints . Any help be appreciated as right now I cannot use radio , 73s
