Hello! I replaced my heat sync on the cpu/gpu after temps getting too high and being very noisy. I discovered quite a bit of dust and debris in the fans, cleaned it out, cleaned old heat sync, applied new, put everything back together to turn it on, and it starts! But no screen. It stays completely black. I’ve tried a hard reset, plugging into another device via hdmi, reseating the ram, ensuring everything is seated properly and still nothing. 
thanks in advance! It seams the cpu is working fine as the fans are modulating temperature based on feel and working well.
