Hardware PS4 BLOD/WLOD after hit by lightning

[ds34]

Hi, the PS4 still turns on and boots to the safe menu, connects to controllers etc. but there is no video output on the screen. The monitor detects the PS4 when I plug it in.
I removed the shield that covers the Panasonic IC and the marked capacitors are grounded.
Can someone give me some information about those so I can replace them?

You're probably going to have to buy another broken PS4 to get replacements.

Why?

When you say grounded do you mean shorted because it is entirely possible for things to be connected to ground. Several of those look more like resistors or ferrites as well.

Anyway lightning is the worst when it comes to electronics fixes.
You can end up chasing things forever (you essentially have a few thousand volts dancing effectively anywhere it likes on the board -- you might have some nice scorch marks and a line of dead components but you ultimately never know), and also find after all of it that more was not killed outright but not going to hang on too much longer.
If I am selling such services it is more of a data recovery type scenario or with that "if it breaks after walking out of my door" proviso.

You might be able to find out values, and if you can get another to poke (or preferably desolder and measure) then do that. For the most part though we don't have great parts lists for the newer game consoles.

those components show short to ground, because of the failure of the Video Encoder IC (components themselves should be fine)

 

[ds34]

How can I check if it's faulty?

 

[testerfan]

remove the chip and see the shorts to ground are gone from surrounding components. When house is hit by lightning , if the system is plugged into TV via HDMI cable - the Video Encoder IC chip is the first to fail

 

[ds34]

The previous owner just told me that the PS4 was connected to the TV via HDMI with a HDMI switch sitting between the PS4 and the TV.
Edit: It was also connected to the router via LAN, but the Lan port works fine (its even recognized by my router and is happily downloading a firmware update)

 

[ds34]

I removed the video chip and checked the capacitors.
All of them are good now, so I assume that it was broken.
Are there any capacitors below the LAN shield?
Also, should I clean the solder pads and reapply solder on it?

 

[ds34]

Well... What should I do about that pad?

You must find a bypass trace and solder it to the pin on IC

Can't I use this trace?

 

[FAST6191]

There are a few pads on that I don't like, and some of the mask being scraped off there means watch for shorts, but will want to see a cleanup first.

The one that is obviously gone leads directly to a via outside where the chip sits. You should be able to either scape away the little bit of remaining trace and install a jumper wire (I like headphone cable for this if you don't have nice thin kynar in stock). If not then find where the via goes and solder to that on the other side of the board. If the others that are cracked/torn are also going to be trouble then one looks like a ground anyway and the other is probably OK.

@Cyan had the exact same thing happen after a power surge. I think he ended up replacing it.
Definitely interested to see if you can manage to fix it.

 

[ds34]

The pad is connected to ground....
Is that supposed to be like that?

 

[FAST6191]

The missing pad (or via/remaining trace) is grounded? 0 Ohms or something a bit more -- continuity checkers can lead you astray.

I don't have the schematics but given there is a massive ground plain a few chips away and behind it then I am curious.

First we can't see much on the picture but there is a giant blob of something there. I don't know if that is shorting something out.

It could be a ground still, just one they don't want to get signals interfere with.

For cheaper PCBs (think the sort of creamy yellow or very dark orange/brown things power supplies for things often use) then with lightning/general high voltage where it shouldn't be you have to worry about the lightning burning a path and leaving behind a nice bit of conductive carbon, might still happen here but it is less common. If it is a mechanically damaged part then the via or trace could be pushed down into a lower layer (which might be another ground plane). This can lead to you chasing things down even further, or doing something more drastic and finding where it pops out, severing the connection there and soldering a wire all the way to that new point.

 

[ds34]

I completely forgot that solder blop

 

[ds34]

However, the video encoder chip arrived today.
Are there any other things to check before installing the chip onto the board? What about the missing pad?
Can someone who has a fully working PS4 please check if the pad is also grounded in their PS4?

 

[ds34]

I will try to put a jumper wire on it

 

[ds34]

Well... I think I will try to bridge these pads to one of the other capacitors
