I have repaired 10 or so A series Samsungs with the c102 green screen/screeching problem. In those cases the tv would click on and off with the screen and sound problem. I fixed a 46" model today That turned on fine and the no video and input menus were fine. Only when you turned on a device plugged into the mainboard(hdmi/component) it would turn into the classic c102 fault. A new 47uf smd cap solved it.

Lenovo Thinkpad W541 Wistron LKM-1 WS MB 12291-2 Works from the network and charges the battery only when it is turned off.

If you boot into Windows and close the lid while working, thereby putting the laptop into sleep mode, the laptop begins to charge the battery.
even checked it this way: I bring a neodymium magnet to the Hall sensor during operation - the screen goes out and the battery starts charging.
Also, the laptop does not turn on without... -

Once the power switched is pressed, 5V and 3V were present.
The things i have done:
1. I have check for shorts on the board, but nothing. The board is short free
2. Not a power switch problem, it behaves the same without the switch ...06-10-2024, 05:05 AM -
