Despite replacing thermal paste, red dot of death still persists.
Hi. I've taken out the heatsink, cleaned out the dried up thermal paste on the CPU/GPU and bottom of heatsink, and coated it with a fresh new coat of thermal paste. I then reassembled the heatsink and fan and did the overheat reset thing. After leaving it to cool completely, I started it up again. No luck. Still got the solid red dot. I've done this twice already. I should mention that the light only goes red when connected to an HDMI cable, I've tried a couple of other cables. The HDMI is not the problem. I got a couple of videos to help illustrate my problem.
Help me, please! I'm losing hope. Got a lot invested in the old thing.
