Hi all, So I am attempting to repair my iCom IC 751 after the power supply fuse blew, after replacing the fuse, what is happening is the radio went from not powering on at all to getting stuck in transmit mode and no frequency display. See the video on Google Drive for what is going on: https://drive.google.com/file/d/1E6OIrouxzKsBvga-TEeeoL5eszbzj2-N/view?usp=sharing This is my first time attempting to repair a HAM radio, and after this happened the radio would not power on. Well, the radio does at least power on at all now that's some progress I guess. I was advised to try replacing the RAM Unit in the radio ordered one today and going to put in when it arrives. Having to order the parts on Ebay. I am wondering what to try next of replacing the CPU RAM unit does not work? Is there a way to test if the motherboard is ok using a multi meter, or a picture of this radios motherbaord here? it is the non A version. Thanks very much.
