70L02H Datasheet PDF – ETC
I have that board for few years ago. She died suddenly and there was not a way to revive.
That evening I found it in a box by chance, looking for a replacement mobo for someone. Thanks to datashfet knowledge gained here on the forum, I immediately found the cause: VRM Q4 was dead. I noticed that the two areas in figure remained united after vrm desolder.
Is there a risk if the two zones are united? I tried to clean the area, but my soldering iron is pretty skinny.
70L02H Datasheet, PDF – Qdatasheet
I would have tried anyway, but I thought to ask before doing fireworks before Christmas There could not be a big loss: Bravo, young man, you’re shrewd. Eventually it was logical that, but for now I have not bothered, because I do not have the component to replace.
Anyway have you spared me for an extra work Catasheet. I really don’t know Maybe your problem is related to the VRM controller, remove the mosfet and test it out of circuit. Must verify the pinout voltages after power on?
I said already about the test of the both vrm: Q3 and Q4 out of the circuit and after solder That seem to be the VRM controller, what a crappy board!
BTW, in your photo there are 2 black caps near the northbigde that looks bloated, check them. I used the last two pictures from internet because have better resolution, so the capacitors are datasheet.

I’ll check in the next weekend. And I cannot find datasheet. This is all i can find.
The solution seems to be too complex – osciloscope needing?!: Originally Posted by alindumitru
