CECHA12 Displaying Green Screen only PS2 games

Hey,

I obtained a CECHA12 console which I have now JB'd with Rebug 4.82. I de-lidded it but in the process of doing that, I scratched a bit of the CPU. I also managed to take out a 17Ohm resistor (between the CPU and GPU), which I ended up soldering back on using small jump wires. The console hadn't been opened prior.

The console boots up as I'd expect, PS3 games play, PS1 games play. Tried playing a PS2 game (either by DVD or ISO) and I get a solid green screen, but I can still enter the In-game PS3 menu. I also tried forcing PS2 Software emulation and I still get a solid green screen, no sound, nothing.

I have performed an OS downgrade as well, but no change. I suspect I've damaged hardware in the process of de-lidding but that doesn't answer 1. Why it won't work even in software emulation mode and 2. other than the PS3 CPU, I haven't done anything else and I would expect the PS3 part of the console to screw up.

Its a weird one, any ideas?
 
You luckily didn't kill the console, but probably some of the PS2 processors are either dead or need a reflow/rework. If your PS3 even boots, it's obvious the problem isn't in the CELL.
 
that's exactly how I'm thinking. The only thing is, I wonder if the track I have potentially damaged on the CPU is linked to the PS2 I/O and its simply not able to start?
In the meantime, I'm tempted to do a reflow on the PS2 chip(s) but any idea which ones?

I don't think so. Any kind of real damage on CELL means GLOD or instant YLOD, it depends of if some traces are cut, or the die is damaged. Many people had problems with the PS2 aspect in a BC PS3, you're not the first one.

Any update on how it went for you? Reading the original post, that's exactly what happened for me too, I even downgraded to no avail.

Are you sure it's not software related? IF the EE/GS was damaged software emulation should still work, but if the issue was with the ps2 emulator not being signed properly or something stupid like that, it could cause issues like that regardless of net_emu or g(s?)_emu or soft_emu..

Just something I'm observing from the situation... :)
It could be something as simple as if you're using rebug toolbox, but not the full version (full version has the BC ps2 stuff IIRC).

Hopefully that helps.... :)
 
This is what I was talking about: PS2 Emulator files are pre-patched for COBRA MODE due to its multi compatibility with original mode, however, if you want to restore original unpatched PS2 emulators, download and install "FULL" version of REBUG TOOLBOX 2.02.08, this fixes the issue with PS2 playback while on NON-COBRA mode.

I honestly feel like it's something software related, I was able to boot a couple ps2 games some weeks ago. Only issue being the ps2 boot logo was a bit glitchy, sometimes blinking for a while then starting the game, other times being blury or it freezing on the first frame. But after that it would boot and play fine. That was a couple weeks ago, and now it seems to be iffy whenever it would boot. I did manage to get it into 1 game but it froze in a few seconds. I want to say it's something with software, but the inconsistency makes me think it's hardware.. I have tried iso's, normally gives me a black screen, and the drive's laser was also replaced to a known working.
 
Create ps2 pkg using ps2 classics gui with compatible game, if it work fine then your issue is hardware, if no, is software.
Ps2 pkg always use software emulator.

Using ps2classicsgui on pc, the game booted fine. So the issue is hardware.. I wonder why the previous attempts there were chances of the ps3 actually booting ps2 games. Was it just doing it to mess with me?! I'll just attach a video I took for someone so you can see what I'm talking about, just the first few minutes and the rest is just me rambling

Hi everyone,

I have a similar issue as the ExtremeCaliber, I'm hoping maybe you can point me in the right direction
So I've bought this CECHA00 console from Japan, I installed CFW Rebug 4.84.2, multiman and webman latest
It plays PS3 games just fine and I've put the fan control to the 40%, even at PS3 Tekken Tag 2 the max temperature I saw was somewhere around 54 CPU and 51 RSX, which are super cool, right?
But when I try to play PS2 games, be it from ISO or a disc (I have PS2 Pal disks) the games would randomly either:
A. Freeze at black screen, when transitioning from XMB to game
B. Freeze at random spot during gameplay(while audio would still play)

In all those cases, I can quit the game just fine via PS button back to XMB.

So is it a hardware issue with the PS2 chip or something in the configuration of CFW?
The seller claimed that PS2 operation was tested and it would play fine.

Unfortunately, I cannot install OFW and test, since I don't have PS2 Japan disc, nor I can try via PS2 classic (as it would require connecting to PSN and activating my console)

Can you please guys point me in the right direction? The information on the internet is so limited on this topic.
Any help would be greatly appreciated.
 
I still think the problem is under the E.E, in the BGAs, as the chip isn't dead, it seems.. The problem is that you can't do much about it.

https://www.psdevwiki.com/ps3/images/9/9d/COK-001_TOP.JPG

There's a chip next the E.E (follow the traces), and everything on that area could be messing with the games boots. In this case I'd try a rework on the E.E, and see if that's the solution, but just a few have that machine in their garage.

Btw, try this: If you have your console set to HDMI, change it to A/V, and viceversa, this to test if the outputs are provoking some erros. Then try a PS2 disc.
 
Well, I'm pretty sad, it seems unfixable for me. I don't have any rework machines to use.

I've tested PS2 games on original 60 GB HDD(since I use 1TB in my setup) and the issue is still there, plugged in AV cable to test, and upon launching the game from XMB, during black screen transition into the game, I would see for a one millisecond white thick lines, with the sound bump (as if you unplug the cable from the sound system while it's operational) and the game would still freeze, you can provoke it by going into PlayStation button menu during the emulation - after you exit the full black menu - the game will be frozen.
I also tried to launch SH2 with AV cable, and the game would exit to XMB with error number 80028F17, meanwhile, with an HDMI it would just freeze at a black screen
Also played with upscaling options to no avail.

I don't know what's wrong with the hardware, I didn't even think that it could be as defective as it is, I always thought it either works, or doesn't

I also wanted to mention that prior to this I was able to play PS2 games just fine (for maybe an hour, I haven't played that much), then I left the console on a shelf for about 3 weeks, tried to play it recently and then these issues started to happen.
I guess the chip was always in some form of danger, and the previous owner wouldn't notice it/told me about it.

I just wonder if it's some certain chip that went bad like ElGris said. While reflowing the whole chip is hard, knowing if it's a component that needs to be replaced would be much easier. I doubt the EE would ever need a reflow but those are just my thoughts
 
Meanwhile, I'm going back to 3.55 stock OFW, going to flash it 2 times, then install back the latest rebug.
I've heard it helped for some folks.
 
Unfortunately, it didn't help at all.

Still, the same freeze, and I did wiped HDD while I was on 3.55.

Seems to be a certain hardware issue.
 
Howdy. I've seen this two or three times and I remember concluding it was a failing GPU. I think all of the PS2 video is piped through the GPU, whether you're outputting HDMI or composite. Pretty much impossible to conclusively prove GPU failure, but one of them went like this:

YLOD -> reball GPU -> works great, good for the first few hours of stress test -> eventually see tint on PS2 games -> reflow EE, swap some AV chips just in case, generally poked and prodded -> no change -> decide to sell it as-is with a warning about the tint, so I continue with stress testing for another 10 hours or so -> back to YLOD

Remember the EE barely gets warm, so the chances of anything going wrong with it are relatively low. I remember working on PS2 slim systems that had dead or totally clogged fans, and a thermal pad that had turned in to dust, and they'd still run just fine.

Sorry I can't be more help than that.

Thanks for your reply.

I imagine if that would be a GPU failure(RSX chip?), then it would fail during my PS3 Tekken Tag 2 stress test.
Since I played the game with zero issues for an hour, then back at PS2 games, it would immediately fail on me.
