First thing is that you dont have to worry about the H-drive becasue the H-drive is assigned for the memory card .......... if you insert the memory card in it then that drive will open too.AS well as the other issue like when you press the power ON button only the power led got power.This can be the problem of the software or the hardware.In hardware this can be solved by changing the OSCILLATOR which is normally like the small metal tube and have two legs and if you see it closely there normally two values ..........one can be 27.000 or 24.000.........so by changing that too can solve your problem..........the other thing in hardware which can solve your problem is the SMD-Transistor which is of 5 legs and have Number like (A36z or A17u or HX-VG or HX-UG or A17a).In software and for the ISP programme like FRM PRO for software ,first you have to put that MP4 player into camera mode.
I think that is enough helpfull for you otherwise give me more details of your MP4 not the outer details ........... "
first greetings to u all.
i 've also similar probs like u guys - only that i found out at this 27Mhz oscillator 4 problematic or low quality - when i heat it with soldering iron the pmp comes to life then when it cools down everything hangs/crashes. some moisture absorption or bad Taiwan electronics. can some body give me the pinout/datasheet of the oscillator vis a vis pads on the motherboard ? how to format the data area of the flash? no support 4rom one of the best multi-billion coy to not issue a datasheet or application note. only push s(h)ell $$$ by selling craps like this. read their quality policy on h-t-t-p-://w3.sunplus.com/about/0104.asp--.and now when this pmp kaputs they will not replace it - Cambridge, Forbes, Innovation. Anybody out their modding this toy for something better.i know it was a bad investment rather expenditure. can somehow make a spy camera with recording facilities, then re-tailoring of the firmware comes.
