OK, The problem is that I can't switch ON the Tablet at all?even when i connect the Charger (The Display is Black) there is no sign of any power goes to the LCD. I opened the Cover, and test all the Check-Points / Test-points (TP's) and found that all the written Voltages are displayed on the Multimeter. accept the LCD connector where it suppose to get a 3.3V input but i'm getting a 1.2V!!! Does the LCD needs 3.3V or it's working with a 1.2V?? also is there any particular Test Point (TP) for the LCD? I'm getting 0.3V on the LCD-HI & LCD-LO test points?? checked almost all SMD Capacitors but can't see any faulty one. I think the that one of the IC's is faulty which result on not supplying the LCD the needed voltage to turn it ON. was trying hard to Google the Internet for the Schematic-Diagram or Service Manual for the Coby-MID7065 but with no luck. The PCB made on 12-2012 which means its almost NEW PRODUCT, and Bought it one month ago from USA on my holiday. I know, I had to check it while I was their but AHHHH Any help would be appreciated..

If you link it to a PC using a USB cable, can the PC see the tablet when you think it should be able to? If you can't get the PC to see the tablet at all via USB, AND the screen never shows any sign of life, then the tablet may be DOA.

You DID charge the battery, right? You're not working with a battery that's on its last legs?

Coby Kryos Android Tablet is not charging. It is connected to a charger but its not charging.


Leave the tablet connected to the charger for 5-10 minutes even if doesn\'t work. Then take out the battery and try with master charger and (switch on the tablet) after that, check whether the previous charger is working again or not again. If it doesn\'t show charging sign, then you have to take it to service center to change the charger connector.

Screen goes black when power cord is plugged in.


Start by checking the power supply with an ohm meter for the proper output. Anything higher or low than one volt means the supply is faulty and will need replaced. This could also be a battery issue, if a fail safe in the battery has engaged. Try removing the battery and see if it works properly on the supply only, if so, then the battery will need replaced. If these two check good, then I'm afraid the problem is with the power management system on the motherboard, and unfortunately the motherboard Will have to be replaced.
