Hi there! (I hope i'm doing the right way to ask this)
I'm working on a Dell INSPIRON 15 7559, with service tag CZ4X2J2.
Im sending both BIOS and EC .bin file and ask if someone can Clear ME it for me.
I guess it's only BIOS to be cleared, but I'm sending both.
It's taking too long to show the DELL logo.
I took this files from another original Dell motherboard which stopped working.
Best regards!
Thank you in advance!...

I have a PS5 in my shop that beeps when the power button is pressed but the light does not turn on and the fan doesn’t move at all. I tried replacing the power supply because it had some roach bodies in it but the rest of the device had no signs of infestation, and it does the exact same thing. Then I tried replacing the HDMI chip (MN864739) because I saw somewhere that it could be the culprit but still no change. Does anyone have any other suggestions or things I should test on the board or is it likely dead? Thanks!Today, 08:36 AM

my laptop has a weird power-on issue.
Once the laptop has been powered on, it can restart/ wake just fine on battery power or Adapter, ONLY If i have not closed the LCD.
If i am running on battery and have closed the LCD (even momentarily). it will not power-on/ wake-up on battery power no matter the battery percentage.
but once i open the LCD and connect it to the adapter (even momentarily) it will wake up gain and I wont experience any issues till i close the LCD.
i do not know where to look for repair.
thank you all for any advice.04-30-2024, 04:36 PM -

Hello! I'm trying to resuscitate a Macbook that the local tech gave up on. I have the board view and schematic and have the main board out of the case.
Of the 4 usb-c ports, 3 cycle at 5V - they all go up to about 1.5A, then seem to switch off, back to 5V 0A, up to 1.5A, and off again. The cycle lasts a few seconds - maybe 3s.
The 4th port doesn't cycle and draws ~0.5A at 5V consistently. It seems it's the port linked to U3100 - it's on that side of the board and is the port closest to the battery and the CD3215C00 chips.
I've read that the CD3215s are...05-01-2024, 06:46 AM -

Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...Yesterday, 03:25 AM -

Good morning

Samsung UE55JU6800K with no image on screen.
I have had this TV many years without fault, however aprox 6 months ago I fitted a new set of backlights as some of the lens caps had fallen off.
Was working fine, until 3 days ago, when watching TV the screen just went blank (still illuminated)
I turned the TV off and left it around 12 hours, and when turned it on again it seemed to work perfectly again. After around 45 mins the screen went blank again.
Left it off overnight and turned it on, and the Smart TV logo came on as normal, then screen went blank.
