Gopro in the freezer is the only way I can get it to work. But it only works until it warms up. I replaced the image sensor and it still does it. I tried putting only the battery in the freezer and nothing. Somehow the freezer if fixing it but only for like 2 minutes. Please help. Thank you so much!
Might be a solder connection that has gone bad. As metal expands and contracts in heat and cold, the difference in temperature could cause a solder joint to get a good connection when cold, and loose the connection when hot. Inspect the board with a magnifying glass for any obvious faults. Using a hot air gun you could try to reflow all the solder joins on the PCB. Hope this helps!
