Hello,
I am new to repairing computer electronics, so excuse any mistakes I make.
A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).
I wanted to replace the capacitor, but I have two questions:[LIST][*]Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?[*]How do I determine the rating/value of this capacitor?...1 PhotoToday, 09:56 AM -

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!...-

by CPRMattI 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

by benwatersonHi 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 -
