Hi Sam, thx for replying.
The PSU model is :

I left the PSU in the storage for 5 months or so, took it out and it was working for 3 total days without an issue(without load, shorting...Leave a comment:

If anyone is interested
the problem was in flat cable connector (it was loose) on the mother board.

ASUS ROG THOR 1200W PLATINUM PSU
Hi guys, hope someone could direct me in right way.
So i got the ASUS ROG THOR 1200W PLATINUM for 15€.
The first time i plugged it in wall socket there was no 5VSB present, so i disassembled it took a little peak inside and left it on shelf for a day.
Next day the 5VSB was present and the psu worked the whole day (outside of computer, shorting PS_ON to ground).
I tested it for a few days like than and then installed in my computer, it worked flawlessley for 1 month.(gaming and such for a few hours).
Few days ago i left it torrenting and saw... -
The markings on the board are R17.. so they are resistors not fuses. To find what is shorted using voltage injection you would need to have a good resolution thermal camera.
You can not start injecting 12V because you dont know through what the line is shorted (example: it is shorted through core which operates at 0.9 to 1. something and you inject 12V you killed it )
If you want to inject voltage inject 0.9V and check with thermal camera.
I hope this helps a bit.Leave a comment:

Re: SAMSUNG UE32F4000AW dead no power

Thank you all for help.Leave a comment:

Re: SAMSUNG UE32F4000AW dead no power
Still waiting for the capacitors to arrive. They arrived in my country on 27.05. We have very slow post office.
.
Once i ordered Gameboy from Japan.
It took 4 days to arrive in Croatia and 3 weeks for parcel to travel 2 km air distance from post office hub to my house.Last edited by krsta; 06-12-2023, 12:42 AM.Leave a comment:

Re: SAMSUNG UE32F4000AW dead no power
All diodes and resistors are ok, no shorted caps arround s3310 mosfet driver
(cant find the datasheet).
Mosfet :
D -> S 0,54V (red probe on source)
D -> S OL (red probe on drain)
G -> D OL (black probe on gate)
G -> S 0,65V (black on gate) resistance 9Kohm
G -> S 1.2V (red probe on gate) resistance 9Kohm
Looks like mosfet is dead. Ill replace mosfet and the driver and try then.
This aluminum heatsing is a pan in the a** to remove,...Leave a comment:

SAMSUNG UE32F4000AW dead no power
Hello.
My mother in law turned the TV on it said no signal, she then unpluged the tv plugged it in and big bang happened. After that no led indicator was glowing.
Took the tv apart and fuse was dead, rectifier is ok, but found the blown blue capacitor near the 9NM60N mosfet between drain and source. Can anyone tell me the value of this cap.
And the mosfet driver model is unreadable like its spilled with some foggy glue.
This is my first time trying to repair a TV, any help would be apreciated....Last edited by krsta; 05-22-2023, 01:59 AM. -

Re: Gigabyte B550 Gaming X V2 knocked VRM components
You have everything you need on the MBO.
The patterns are repeating.
Desolder the parts measure them and put new ones on missing pads.Leave a comment:

P1 Mini pocket projector horizontal lines
I found P1 Mini Pocket Projector in original box without remote on the street.
Charged the battery and when powered on noticed 1, 2 or 3 distorted horizontal lines.
I havent opened it yet, the warranty sticker in unbroken.
I was wondering if anyone knows what the source of the problem could be, maybe a known issue. Take a look at the attachments.
Thanks.... -
Re: Asrock Z170 EXTREME4 Strange behaviour
Flashed both bios chips with latest 7.50 bios version -> same symptoms.
Then flashed the same version of Intel ME FW (11.8.50.3425) -> same thing.
I noticed when installing drivers that LAN card cant be installed and it has
"Error while starting" so i disabled it in bios, and now everything WORKS(except LAN card).
No more 19 error on debug display,
no more fan spinning when MB is off,
i noticed that when MB hanged with 19 error main bios led was lighted...Leave a comment:

Asrock Z170 EXTREME4 Strange behaviour
Got the motherboard free of charge because it was not powering on.
8 pin CPU power connector is not shorted, and all pins are acounted and ok.
So i put the Pentium G4400 inside presed the MBO power button and still nothing.
5VSB is present and 3.3V also.
Now the strange part.
If i press and hold power button for few seconds nothing happens but if i press it again (1 short press) after the long press the mbo starts and i see the 19 debug code on display.
I then power it off (long press).
After this...
No activity results to display
