Output signal problems after replaced HDMI

Good day to everyone!


I got my hands on a PS4 which had its HDMI connector butchered. The connector pins were torn out of the housing of the port, so it wasn’t hard to find its problem, why it didn’t give any output.

Nevertheless, replaced the port and it’s supposed to work fine, (measured the pins connection etc.) Although after reassembly the console turns on, but the output signal is dropping weirdly. Sometimes it works for about 10 seconds or so, then starts dropping signal over again. Also, some kind of static noise, without sound is visible for split seconds sometimes.

Also could someone explain me what the heatsink clamps are for?

When I loosen the screws the cooling fan bursts to a higher RPM, could this be an overheating issue? I never see any warnings for overheating, and the problem persists even if I just turned on the console.

After I messed around with it, I could play long minutes even, although the problem doesn’t seem to stop completely. Last time I had no picture but sound


I’d appreciate any help, and thanks for reading!

Update (02/22/2019)

Hey everyone and @soft_solutions as well!

Is there any way to know what kind of diodes are on the board near the HDMI?

I may have some stuff laying around which I could use for replacement, and I’m thinking of ordering the HDMI chip as well.

I’d much appreciate any help!

If anyone may ever read this, with the same problems, check the diodes near the HDMI, we found out some of those were short circuited!

Hope I helped someone!

2 things

1 fans speeding up because you may did not put the thermal past we’re putting it back together PS4 cpu are very sensitive and can go off with in few weeks to couples of months if you don’t use thermal past on the cpu.

2 the reason you don’t get out put signal may be because of cpu overheating or there might be hdmi ic faulty or short in hdmi port.

information based on a technician myself

Hey! Thanks for the help!

I've used thermal paste, coated well, and it's brand new, so that shouldn't be a problem.

Also I've tried measuring some components near the HDMI, and found 2 short circuted diodes, while finding out the HDMI encoder ic is faulty as well.

Well, too bad I can't get my hands on a donor, so it may stay like this for awhile.

Thanks again for the tips, much apperciated!
