hello friends, it's okay

Hallo friends..., Yup..

Sorry I corrected what I said, my old brain remembers R2001 & R2002 are resistors connected in parallel, and that's WRONG, the 47k resistor is only installed in R2002..., Tq RIP-Felik with his math formula reminded me.

Right, there was a GLOD for some of the cok-001 that we installed, at that time we used cxd2991 and cxd530x, I forget the exact cause of the GLOD happening in cxd2991 or cxd530x or both can happen, which is clear with a solution changing 47k can eliminate GLOD, so we apply until now. the memory...

I haven't been able to open the shop (it's been more than 1 month), while all the equipment and motherboards are in the shop, later when I open I will make sure the cok-001 has a problem or not for the PS2 games. I also don't want to give input that I haven't tried, because it will only add...

right, it's empty, there's no component in R2001. you can also put 47k into R2001 but leave R2002 empty I'm sorry, I'll explain in more detail in the future....lol

Hallo friend.. the 47k resistor that you have taken is correct, the 33k size value that you measure with the installed position is due to the influence of resistance in other components R2001 and R2002 removed, put 47k in place of R2002, this was done specifically for cok-001. to avoid GLOD...

Hello friends, you have edited it very quickly, thank you. for the SEM-001 "CLK" pulse I will confirm again later. Thank you also for making the guide, can you include a video of the movement of the analog meter, because it will explain more. The method that I have is very dependent on the...

Hello friends, well I've heard from DeathEnd, I just found out there's a problem with the PS2, unfortunately I haven't been able to try it (because of isolation), when the shop opens (August 9th) I'll look for the problem. So far, no one (Indonesian) has talked about the PS2, so I just found...

Hello friends, happy to be active again on the forum, the condition of Indonesia is still Lockdown lv4, my family is also exposed to covid (but now everything is healed), sorry if I not active. I want to chat with you, do you have whatapps? There are many things I want to ask, I'm new to syscon...

Hallo Friends GLOD problem, the causes are many, 1. Ram CellBe 2. RSX Ram 3. OS software 4. IC AV/HDMI 5. HDD Each cause has characteristics of damage that can be checked. Usually I use an analog tester through the "CLK" point, and each cause needs to be explained as well. CellBe RAM: a. RAM...

VDDIORW is connected with C3, see the marked picture VDD HDD voltage source C3

It looks like my older brother made it from a different angle...lol, sorry if it doesn't fit when rotated 180°, try to look in the mirror, maybe it will fit. at the time of making the schematic maybe my brother saw the reverse side of rsx

I think everything can be reballed well, a tip from me, specifically for the cxd 2971, you should install the temperature sensor on the pcb especially attached to the rsx tin ore, sticking to the outermost tin ore is enough, the original sony tin ore for the cxd 2971 will melt at a temperature...

Maybe this can to I see from my drive, from 2014, the post from my brother "kiaw"
