Chosen Solution
PS4 tries to give a signal (TV says “processing signal”) but then it goes to “no signal.” Does this in both normal and safe mode. PS4 seems to boot completely. Blue light turns white. Known good TV and HDMI cable. I am thinking of replacing the HDMI IC (Panasonic mn864729) but it is expensive. Any ideas?
If the HDMI port looks good then it’s is very likely to be the ic chip. The ic chips on these go out a lot more than the older models. I always check the port very carefully, test the diodes and resistors. If they are good then I replace the chip.
Still could be an hdmi port issue due to the resolution
