hi there.
in my hands i have philips tablet.
I saw some black substance arround the 3 boards for the battery. Like a battery has been leaked. Of course i can picture and show it to you.
Have desoldered the three wires and put them back. Have connected again the LCD, digitizer and camera connectors. The tablet wont power on - nothing on the display and no vibration.
Where can i read some good guide or something?
Are there typical problems in the hardware of these devices?
What can i check in the circuit without desoldring?
At all i replace lcd, digitizers, batteries and make software changes, but will be good for me to do not very hard hardware repairs.

Thanks in advance
