    Hi, i have a fat model schp-30004 ps2 console.
    My problem was started a few weeks ago.My console was turning on but showing no image or sound, just black screen.But after waiting 5-10 minutes and pushing to the reset button was solving the problem and i was playing as normal.
    After that, waiting times started to getting longer and longer so i'm turning on my machine staying 2 hours as working and resetting but nothing happens just black screen.All my cables are ok,no problem with them.

    I have some beginner level electronic repair skills so the problem looks like a blown capacitor to me than i disassembled my console and reached the motherboard.Before that i checked my power board it was ok.

    I saw that a solid capacitor which was near to the power and AV output was different than the others.It has a yellow burn like dirt.So to say,it was burned inside to outside.I showed it in the following link with red arrow:

    I am not sure this solid caps good or bad.Do you think it is blown or burned.

    if it was blown, it would have split the top open & that is not a solid capacitor as it is the standard electrolytic surface mounted capacitor. that appears to be flux residue.

    Did you have your device modded?Some enthusiasts enjoy modifying the machine to give it the ability to play imported games. If the modification is performed improperly, it can cause a black screen. Restoring the unit back to the factory setting can fix the issue, but if a component inside the console was damaged during the modification process, it might be permanently broken.

    the one above the three fat ones.. to the right side top.. actually I would be suspicious of all the thin ones.. hallmarks of bad caps all over them.. green and tall.. the short fat ones are usually fine..

    without checking voltages of rails it's not easy to diagnose a non starter.. my stock method is to replace any green skinny caps.. which usually works these days.. but honestly.. a ps2 is so cheap used now that it's hardly worth the time and effort..

    Beginner level soldering skills?.. probably more likely to burn the tracks off the board.. .....
