Hi, this is about a 1st generation erista switch. Power button stopped working, all else was fine.
Made double and tripple sure, that button, cable, connector is all good and everything around the connector on the mainboard is fine.
Then I used board layer xrays to figure out power button signal is routed to the max77620 chip.
I actually found shorts around the chip - so yay (I thought).
Ordered new chip, removed chip, shorts still present (lesson learned, first desolder the caps).
Here’s a pic of my board.
sorry can’t put links or pics in my post.
All the red circled caps care shorted. moved the topmost one and the one below (in pic still in place) and they were in fact bad.
- What’s the calue of the circled components and the size?
- It seems strange to me that all 5 of those caps went bad. Any idea if there could be another underlying problem? I’m worried if i replace them they might get blown again because of another problem.
