Unfortunatelly no, didn't work.

I opened the reader for unplugging the accu, hoping and so an, hoping this might help. It didn't.

Multimeter measured 3.8V, so it should be O.K., doesn't look bloated. Test points all over the board are showing some voltage.

As you can see from the pictures form the inside of the LB Mars (don't know, if there are already some pictures around in the www), the LB Mars has a very informative board layout including a debugging port.

Power switch and reset switch should be O.K. aswell, you can measure they are switching.

A little bit strange is, attached everything of there remains some mV at the test points. Voltage is draining during measuring. Measured later again there is slightly a higher mV as if there is somewhere a buffer.

But a brick is a brick. This was my 4th ebook readers and my first one which died not because of a broken display.
