I looked it up online and saw that it’s most likely due to a short circuit. So I tested the capacitors using the multimeter’s beep mode (I don’t know much about electronics), and I noticed that there’s a whole section where the capacitors beep on both sides, but I don’t know how to tell which one is faulty (see the photo).

Also, the liquid metal doesn't look very clean, and I wiped away a very small drop from one spot on the board. Should I remove it completely and reapply it once it's repaired?

If you have any advice, I’d love to hear it, and I’d be very grateful! ⏎

Thanks in advance!

I need instructions, how to replace batteries from my PS3 Motion and Navigation Controller.

Thanks in advance.

Manufacturer : "ShanWan"
Product : "USB WirelessGamepad "

Device ID : HID\VID_2563&PID_0575\7&17507071&2&0000
Hardware IDs : HID\VID_2563&PID_0575&REV_0200 HID\VID_2563&PID_0575

They were working fine until I transferred my windows from old SSD to new SSD.
When I enter every game I have series of button ( I think they are repeating ) is pressed every 5 to 20 seconds. for example circle back back down start circle even some keys pressed together( up+start+circle).
it is very amazing when I turned the controller off and just dongles attached.
I have tested it on android device and my smart tv and there is no more automatic buttons

So, I just did my first real teardown to get rid of the dust on my console and to figure out why it wasn’t turning on. Unfortunately, the case won’t clip back on, specifically the right side. Has anyone else had and/or fixed this issue? Thanks!

My PS4 Pro suddenly desided to die on me. It is showing me the blod. Now, I have been doing a lot of testing an experimenting trying to figure out why, but I haven' t really found anything. I'll describe first what it exactly does and then what i tried.

The symptoms:

1. I plug in an HMDI and power cable
2. I press start on the console (my controllers are dead)
3. The PS4 Pro turns on with a blinking blue light and no display out.
4. Extra info: the fan spins up to a slow speed, the disk drive does eject and accept disks and turns them aswell and the HDD does spin to life
5. nothing else happens except it gets very hot to the touch above the psu (but imo this could also be cause the fan is barely spinning)
6. i turned it back of since there was no change for 25 min
7. I tried safe mode by pressing the powerbutton longer from the power off state
8. it first beeps once and turns on with the same blod, while i am still holding the powerbutton
9. after 11 or so seconds it beeps again and it turns back off. so no safe mode possible

The things i already tried:

• safe mode
• replacing the cr2032 coin cel bios battery
• different methodes of safe mode and wired controller combinations
• hdd removal and replacement
• differen power and hdmi cables
• different tv and monitor
• opening everything up for cleaning and checkup
• checking on bad capacitors or resistors, checking fuses
• checking for rust or other fysical problems
• checking for shorts on the power rails of the main motherboard
• checking the output voltages of the psu, which are 11.8V on the 2 big metal pins and 4.8V, 4.6V and a feedback 3.2V one on the little cable connector
• connecting a desktop 300W PSU to the 12V rail of the ps4 while keeping the 4.8 and 4.6v of the og psu

Whatever i try, it keeps doing the same thing. There is no change whats o ever. Also important to know, the blinking blue light stays on forever. It's not like the PS4 Pro turns off after a few seconds or minutes.

I think i have mentioned everything i tried but i might have forgot some, ill say those if i remember when someone commends.

But, my main question is the following. Since none of the results seem to indicate a specific component, like for a short on the 4.8V rail it is often the HDMI encode chip, i have no real next step available to check or test. Is it worthed to mangle the PSU wires to also use the 5V of the Deskop PSU and completely remove the PS4 PSU? Should i try to buy a new PSU for it or does someone think its not enough evidence that the psu is not the culprit? Should i just go for a second hand PS4 Pro? Most PS4 Pro's in my region go for about 180 euro's if i recall correctly, and a new PSU for 65-90 euro's. If someone says it needs to be reflowed I'd probs buy a second hand one cause the reflowing in my region is like 135 euro's without the probably mandetory diagnose of 90 euro's. I can not do a reflow myself, cause i dont have the correct equipment. Any help is appriciated!

PS.: for clarification purposes: yes, i opened the PSU and all other components to test them. Do not worry, I am an electronics engineer, i know what i am doing and am comfortable to do so. It's just that i do not know the PS4 Pro and it symptoms since i mainly design electronics, not repair them. And the repairs i do do are usually Desktop, laptops or household electronics. Also i apologise for  my bad English, its not my native language.

Hello!

This answer is an extension of the comments on the answer of @dan0 .

So, I have some extra questions related to the reflowing. I'll write down my plan followed with the questions.

I am in possession of a flir camera, an hairdryer and an hot-air-soldering station. My plan was to first heat the complete motherboard with the hairdryer to make the complete board equal in temperature. Theni would proceed with the soldering station with the biggest modus (no extra tip) of 1.3 cm wide to make a looping movement over the APU and the RAM in a fluent and as consistent as possible movement. At least, that was my plan. However, there are a few things hope to get information on regarding this:

• How am I supposed to do both the APU and RAM? They seem to be on the oposit sides of the motherboard. If I heat one side, won't the other side also get reflowed in the worst way possible, since it's upside down? Afterall, this is the motherboard with the red circle around what i presume is the RAM:

• How hot does the motherboard need to be with the hairdryer? I can measure this with the flir camera.
• How hot do I need to set the hot air soldering station?
• How fast does the hot air station need to blow: 50%, 20%, 80%, ...?
• Will this hairdryer and hot air station combination work instead of the hot air gun in the PS3 video?
• Does the APU and RAM need to be a certain temp or do I just need to set the hot air station to a certain temp and keep it on the APU for a certain total amount of time? And in either case, what are the amounts?

I like to have a lot of information so I wont break it unnecessarily. There are a lot of questions since I have never done a reflow,

Thanks already for all the info!

I’ve already ruled out the Ethernet cable by testing with another one, and I’ve seen others report similar issues online without a clear solution.

Side note: my HDMI port is loose, and I have to angle the cable for a stable display connection. I’m wondering if there could be any relation between the two issues maybe heat, board stress, or internal damage affecting both ports.

Would it make sense to replace the HDMI port first and see if that resolves the LAN issue, or is this more likely related to the Ethernet port or its solder connections?

I read on this thread that this issue is caused because of dirt between the contact surfaces of the cable sheet and the trigger and the solution was to just clean them. I've replaced the cable sheet before so I knew how to clean it safely, and so I did, but after I reassembled everything the r2 trigger stopped working all together. The reading in DS4Windows show that the R2 is completely dependent on the left stick now. It doesn't spontaneously activate itself now, but the &&^&^$^ left stick is controlling it.

Here is a demonstration. Can anyone help me out with this? What could be the issue? I found this thread on IFixit which describes the exact problem, but its for the Xbox controller. I don't seem to understand what parts are the DS4 equivalent to be able to narrow down the problem for myself.
