I have a TYT TH-9000D 220MHz radio that, until this afternoon, has been working just great since I purchased it about a year and a half ago. Today the supply that was powering the radio accidentally got turned off while the radio itself was still turned on. When I restored power the display was scrambled, looking like a mix of Chinese characters and partially formed numbers and none of the controls function. A "locked" symbol appears on the top right had portion of the display too. None of the controls seem to function now, including the power button. I am unable to perform the "reset" function as outlined in the manual because I can't access the menus due to the pushbuttons all being inoperable. When I apply power the radio comes on and displays the messed up gibberish. Does anyone know how to do a reset on this model radio when in this condition? I did try hooking my computer up with the programming software to see if I could revive the radio by reloading the backup copy of the channel data, etc. but when I try to write to or read from the radio I get an error saying the programming cable isn't connected or the radio isn't on. The computer and the programming software are in agreement about the cable being connected to com3 and Device Manager says the cable is working properly so I'm pretty sure the microprocessor in the radio needs to be reset before I'm going to be able to get the programming software to talk to the radio. Has anyone else experienced this and come up with a fix? Does anyone have any ideas I haven't tried or thoughts of something I might be missing?
