First I'll say that my dock, monitors, cables, etc, etc are fine, all work with other Switches.
So I bought this Switch as faulty - the USB-C connector had some bent pins so I replaced this (have done this a number of times now on other Switches so I know what I'm doing - I'm also fine with microsoldering).
After replacing the USB-C connector I charged up the battery via an external adapter (not in the dock as I was using it with my own Switch at the time).
Once charged to a reasonable amount the Switch booted just fine, games could be played as a handheld, etc. However, there's no HDMI output when docked.
Checked all system settings, even did a factory reset.
Note: this Switch is running firmware 3.0.1
Using my multimeter I buzzed through the 'hidden' pins on the USB-C connector (I have a post elsewhere on how to do this) and they're fine, all connected.
(I've had this issue once before - replacing the PI3USB chip fixed it - well, in a way - with that Switch I replaced the chip, it didn't help, but on putting back the original PI3USB the HDMI output was restored so I guess there was a dodgy connection on that chip that happened during manufacture (so really I should have re-flowed it first)).
Anyway, back to this faulty Switch with no HDMI - I checked for any shorts, etc. Then I re-flowed the PI3USB - no change. I replaced the PI3USB - no change. I decided to replace the M92T36 - no change. I then decided to take a wild stab in the dark and change the BQ24193 (that can cause some weird things when faulty) - no change! Note: I checked for shorts around all of the replaced chips.
So I'm stumped.
Any ideas please?
Is there anything in particular that I can or should measure with my multimeter or any other chips that could cause this?
Thanks
