There is no repair guide. M never wanted these repaired. I suspect liquid damage. Get a small Torx screwdriver, likely a T-6 and unscrew all the screws, making certain you located the one near the antenna. Open? Look at the main board. If there is a whiteish coating, it is liquid corrosion. If you want to try repair, get some rubbing alcohol, a clean rag and q tips. Start with the rag, dip and rub, but not hard. Do not dislodge the small parts on the board! Then move onto the q tips for smaller areas. This can easily take 30 minutes to do a good job. So, you have an hour a radio into the repair, maybe more and no guarantee it will work when done. You can test the radio while apart by holding the battery to the contacts. Best of luck!
