I bought a broken v1 on ebay and was able to clean up the liquid damage and fix the corroded lcd backlight cable. The fan seemed to be broken so I swapped it with a working one, but it’s on constantly when booted.
I did try another working fan and it does the same thing. I cleaned up the connector and it doesn’t seem to be the problem. I’m not sure if it’s the fan or actually running hot. FWIW, when I was testing without the heatsink, it did overheat while installing a game and I haven’t had that happen to other switches in the past.
Can anyone suggest some components to test to try and identify the issue?
Thanks. I’ll have to take it apart again later to take a pic. It’s all back together now and everything seems fine except the fan being on, but I played a game for 30-40 minutes and the battery was half gone. I’m not sure how much of that is from the fan and how much is from a beat up battery.
Here’s the IC. I don’t recall it being that bad from the liquid damage, but the pads to the lower left of it weren’t that great and I had trouble with it for the trinket install.
