I can't thank you enough for making this video. I have a PS2 SCPH-39001 that had garbled composite output (crazy rainbow colors and loss of sync on the display). I was at a loss for what to check but after watching this video and checking the 47 ohm resistor networks between the EE and GS chips found a resistor in RB121 that was at 250 ohms. Jumpered it, and boom, video is working perfectly again. Cheers and thanks so much! 😁
@@MRGRIMMINFLAMES a jumper would be a piece of thin wire that is soldered across the bad resistor to temporarily restore the connection. You can get the service manual online from many websites to determine which resistor networks to check and you'll need a multimeter set to ohms mode in order to measure the resistor networks one by one. Also you'll need a good soldering iron with a small tip to install the jumper, make sure to use flux.
I tested all of mine and none of them were out of tolerance so I washed the mobo with isopropyl alcohol and put it all back together and had no issue afterwards. Strange but I’m not complaining
Are there long term detriments to jumpering the resistors like that? Wouldn't it be better to replace the failed component? I'm having this issue with a PS2 right now. Thank you for the video, it has been helpful.
Nice stuff The game being played for reference is Stargate alpha for ps1 18/2/2022 - I attempted a clean of my motherboard and got it working, though with my PS2 I didn't bother with this resistor hack in this video, I merely cleaned around the graphics chip and resistors with some isopropyl alcohol
He used a multimeter to measure the resistance values across the resistor arrays, a screwdriver for screwing/unscrewing, and a soldering iron + solder for making the resistor jumpers
@@idreestech I will do this then, thanks. If it does cause damage its not that big a deal anyway because I can just buy another motherboard or entire ps2.
In many cases, especially with older hardware like the PS2, these resistors are included to fine-tune performance. Bridging them essentially removes their impedance, which can increase signal strength but may also slightly increase noise. However, as you've noted, Sony sometimes bypassed such components in later designs where the impact wasn’t critical, meaning it could be relatively safe to bridge them.
I had thia error for the Game KING KONG. All of the sudden after 2 years of jot playing the game it surprisingly resolved on its own idk what happened but it was a memorable moment of me playing the game again 👍.
Greetings, I have a SCHP 30001 that once powered for the first time in the day it displays in color but after a restart it shows in black and white. I checked the resistors like you did in the video but they all seem to be within the values. It happens with 3 different composite cables in a CRT TV, Could there be any other place I should test?
Greetings! It sounds like an unusual issue. Since you’ve already checked the resistors and tested with different composite cables, the problem might be with the video encoder chip or possibly the AV port. You could try cleaning the AV port's contacts, as dirt or oxidation could cause inconsistent signals. Another possibility is a problem with the TV’s input settings-some CRTs have issues switching between color standards (NTSC/PAL). Try toggling the TV settings and see if it helps. Let me know if you find anything!
@@idreestech I cleaned the Av port and the soldered contacts but the problem persists. My assumption at this point is that since this PS2 is currently connected to an internal HHD it might be drawing more voltage than the psu can handle. I tested the PSU with the console off and the output to the board was 11.6v. I’m trying a PSU replacement board to see if maybe that’s the issue.
Have a PS2 FAT GH-023 board with no video no sound. All networt resistances are fine. Had PS7 blown because controller board flex cable was damaged. Replaced PS7 fuse but still no picture or sound. The dvd drive eject button works and found no shorts on LA6508 and on the other IC that controls the dvd drive motors, laser, spindle, tray, etc. Fan spins and works. A/V cable works on other ps2. Tried the blind rgb/composite trick but didnt work. Any suggestions are appreciated master?
Is this the same as the PS2 Slim? Because mine has a weird issue: when you start up the console, the screen keeps glitching for several hours, and all of a sudden, it goes back to normal. I've also tried my composite cable with my PS1 and PS3, and it's working fine.
Thank you! I had two resistors not working, jumper was not necessary just resoldered the conections and lines values came alive! I think its because my ps2 fall down and maybe broke some conections betweeen transistors! Thanks thanks!
Friend help please!! First great video thanks!!! Look, from the EE processors side I removed 2 resistors and carried out the process of jumpers, at the bottom I have all of them with values diferents than 47 and my question is: can I remove them all? None of them work on the oposite side of the EE, if so can I remove them and will it the ps2 Will work without a problem? Or do I have to leave them there and only put the Jumper over ir? because when I remove the top ones it still works but still distorts the image. Are the resistors essential or can I remove them and change them for jumpers only?
Resistance materials are often used in various applications, such as electrical circuits or devices, whose primary function is to impede the flow of electric current. However, external factors or environmental conditions can lead to changes in these materials' molecular or chemical structure, causing them to degrade. There is no need to use resistances to couple the data between two chips. And also you must have noticed that in advanced consoles or circuits, SONY stopped using this component. So the last part of the question's answer is yes.
I thought this video was fake but I just fixed my PS2 by adding jumpers to bypass damaged 47 ohm resistor networks. There were 3 bad resistors in 2 of the resistor networks. Thanks so much for posting this. For anyone else doing this you need really thin wire for the jumpers. I used some strands taken from from a larger 22 AWG wire. Take your time and test every resistor in each network I found 3 bad resistors.
Have you seen issues using the jumpers in terms of additional future failures. I’m debating on replacing the resistor networks but if you haven’t seen any issues using jumpers then maybe I’ll just leave them.
Hello, I need your advice please, my ps2 works fine on the screen, but once I start playing any games, the display goes wrong, like broken, pixeled and a lot of lines, I don't know if the problem with the device or with the TV cable
You have to check the device on another TV with a new cable. If there is distorted video then change the cable. And if the display Graphics are broken it could be a problem with your PS2 device. With a PS2 Slim a distorted video caused by a fake power adapter.
What if master with sounds but distorted display? I checked mine and did the procedures what you did, its all seems fine 47ohms 46.6-47.2ohms, but stil distorted display, i did try the blind test swrich down X, down 3 times then X, then left or right to switch ycpbr. Component or av only.. still the same
@@idreestech yes i found one set of network resistor at the back between gpu and cpu but the problem i make a jumper wire through there vias, it turns i hot quadrople image :) i think it needs 47ohms with thouse 8 traces
I think i'll try to buy some smd small 47 Ohms resistor like 402 size then each one of the traces connect to it using jumper wires, because there to tiny to get into the 8 pairs of connecting network rsistors

First, check for its internal power supply. In Ps2 Fat models as you put the main power in it, 12 Volts get life in the Ps2 Fat models. But in slim models the case is different.
hi buddy my chipped ps2 freezing randomly sometime at matrix logo sometime during a game some time after starting post matrix logo black screen means its ramdomly freezing this problem started when i was playing game in very hot room without much cross air ventilation i think due to over heating what could be the issue any advice would be extremly helpful
@@idreestech no I couldn't get to the motherboard because I don't have the small of a screwdriver but the system seemed pretty clean when I opened it so I really don't even know why the display is distorted I guess I'll just buy another ps2
hello sir nice content im also having an issue with slim ps2 the display is not normal bright but dull and oversaturated colours during games can you recommend any solution ill be extremly thankful to you regards
Hey man, lately when I turn on my PS2 fat model works fine and flawless but after 10-15 min approximately it turns into black and white screen any ways to fix that or I just need to get another one?
Si conecta las resistencias de la red entre sí, los datos se cortarán. Todo lo que tienes que hacer es conectarte o saltar para mantener la continuidad.
