I had sent this message a day or so ag but I really doubt it went though coreectly. So what I wanted to know is, if there is a flash memory chip in a TSOP package in a satilite reciver box, and I want to reprogram it while its still onboard, what are the chances that the programming voltage[s] could o harm to the other components? No, i'm not tring to steal satilite tv, i'm configuring a satilite and reciver to do pure data transmission for a networmk I'm setting up.
