I have one working tsu6000 already( in process of programming) decided to buy a non working one and start tinkering(new to electronics tinkering but figure I can learn). Just received it put a battery in it and screen was blank but could hear the buttons beep when touchscreen was pushed. Reflashed the firmware after that. Then screen came on for a while but looked more gray than color. Screen would work sparaticly. Then after about ten minutes charging end of remote was very hot. I have removed the battery and have not opened it yet and probably won't have time in the next few days but thought I would pick the brains of all you experts to see if you have any thoughts.
