Okay.. stange.. I somehow got my Tx7 working (meaning I opened it up,got confused, did nothing but give it a can of air cleaning, closed it, and it worked)
Given its age, I would still like to change the backup battery. I have another battery for it. My question is.. how do I get that stock battery out so I can replace it. I couldn't get it to budge and I couldnt see underneath it. Is it soldered to the board ? If any of you have replaced a Tx7 battery, please let me know how its done.
