Hi folks. I'm helping a non-techy friend by trying to fix is older zenithink tablet. I have been having troubles identifying the specific model, but thats the least of my problems because I can't even get the damn thing to boot! I have read up on some forums that their is a cable that sometimes comes out of place or disconnects, hence leading to a white screen. But if this were the case, the tablet should still boot and make some sort sound..this is does not happen. Not even a tiny speaker 'pop' on startup (damn hardware's quiet!). I have left it charged via usb cable for a few hours (i do not have a AC charger at the moment), but i don't see a charging indicator light that everyone has mentioned in some of the forums. WITHOUT the micro SD card in, when holding down the power for about 3 to 5 seconds, it'll give me a bright white screen for only a few seconds before the screen turns off again (its not dimmed, but it completely turns off). WITH the micro SD card in, turns out, I get the same thing!!! I reset it every time in between 'test boots' to insure that the tablet may not be booting or already booted from a previous attempt. I did some homework on the flashing process, and it is quite a bit different from smartphones which i'm more experienced with. I cannot seem to get the computer to even recognize the device. I followed the directions; the power and main home button on the front while plugged in, but with no luck. I've also tryed the power button + menu button, and even the power button + menu button. Still, no luck. I'm pretty stumped guys! I'm usually pretty good with gadgets but this one's got me stumped. He also got it a couple years back, so i think he doesn't have a warrantee on it. I dont really know where to turn next because i can't even get into a kernal to flash a new rom, or even get the computer to recognize the bootloader. Ideas? ENLIGHTEN ME WITH YOUR WISDOM P.S according to my friend, the tablet worked fine at one point then just crapped out on him, im thinking its firmware/software related butttt theres always a possibility it has defective hardware.
