I purchased a broken switch in hopes to repair it to use as a docked device. Complaints were that it would not charge and that there was no screen. Watching Steve’s videos, I opened the switch up and determined that the USB port and video chip were bad. I have replaced both and tested the switch again. I get .40-.41a charging. It does not drop to zero and start fast charging. Knowing that this would be a docked switch, I put it back together enough to test the screen, and I get nothing on the screen but still get .40-.41a charging.
I have tested a lot of the big capacitors around the board and none of them are shorted to ground. I have replaced the M92T36 chip because I ordered a new one and the same thing.
So the P13USB, M92T36, and usb port have all been replaced. I do not think I have a bad battery because it is doing the exact same thing to the other battery I have from another broken switch that was used for parts before I bought it on ebay (crappy of that seller).
Anyone have any ideas?
