Witam.
MB: 6050A2563801-MB-A02
CPU: SR15J
PCH: SR17D
GPU: GT750M
Płyta nie uruchamia się. Są oba napięcia ALW, które po chwili zanikają, a po naciśnięciu przycisku pojawiają się ponownie ale znowu na krótko. Pomiary wykazały, że na dławiku L6300 są ok. 4ohm-y. Dławik jest w pobliżu PCH więc myślę że jest od jego zasilania. Po wylutowaniu mostka zwarcie znika. Kupiłem niby nowy z Ali. Po wlutowaniu mam zwarcie. Albo układ uszkodzony albo..., no właśnie co? Schematu niestety nie mam.
Proszę o pomoc.

Hello!
What is an actual resistance to ground on this coil after replacing the PCH chip?

Hello.

Right now I have the power supply disconnected between the coil and the PCH. On the PCH side it is 0.2ohm-a and on the coil side 3M.

You may overheated the chip during soldering, otherwise you have a solder bridge between the balls under the chip.
I doubt you received a chip that had a shorted power rail.
