^ I have the exact same issue. The unit shuts down after a few minutes and doesn't turn on until it cools down. This fault does not register in the protection history. The SMPS board is scorched around the ICE chip. I have recapped the SMPS board. Found a few bad caps and a couple dead caps (adjacent 33uF and 47uF at the center - C873/C874). After recap the shield around the SMPS isn't that hot no more, but the unit keeps shutting down, although it takes longer for it to do so. Currently ordered a few ice3br1765j chips to replace the suspect on board. Will report later.
