Hi Can you help? This is the description of the problem. I have an epad ZT-180 The model number is ZT180 0102A SRTA1030S6 It has a ruby v1.4 motherboard. When you press the power button, nothing happens. When you plug in the charger, the red LED comes on. Press the power button, and the blue LED comes on for 3 seconds then disappears, and the red LED comes back on. There is nothing displayed on the screen. Ive left the unit on to charge all day, but still no difference. I have opened up the unit, and everything inside looks OK. The cables are attached correctly and there is no signs of overheating. Ive tried pressing the reset button, but nothing happens afterwards. I have tried loading new firmware from the zenithink.us website but nothing happens. Effectively, the unit is non functioning. There are many users on the internet posting similar problems, but no solutions. Any ideas greatfully recieved particulary if you have the solution!
