3310 lost signal

[jules]

hi
my3310 has been playing up!!!
after i fully charged the battery i would have it turned on and occionally make calls for about a day then the charge was down to zero and i would have to recharge....so i put a good working battery in it and it was fine for a day....then the phone got warm and switched its self off... wen i turned it back on it came up sim card not accepted hmmm!!!!
i then re-flashed the phone and now i can not get a signal i have tried a number of times re-flashing it and still no signal
is this a hardware problem ????
thanx jules

it's a kind of a hardware problem...you should remove the COBBA.and make it new balls.And clean the board(with'cif mouse')after that flash it with MCU+PPM.then calculate the faid..thats all.....

if you've replaced the cobba and are sure software has been reloaded ok, i would check the output on PA or Diplexer as these
are prone to shorts, excess current drain/heat.
