PS3 Newly Restored CECHA01 Not Playing PS2 Games

I have a family friend that's worked in console repair for 20 years now. He said he received a A model in 2011 that came in for repair with this issue and said he couldn't diagnose the issue. So the customer sent the console off to Sony for repair. It came back with a newer RSX a different one from the 90nm one. (He doesn't remember if 65nm or 40nm) So @Timbo9876 is probably right sounding a lot like a rsx issue now. Were you careful when removing the heat sync from the cpu and gpu? That old thermal paste can be like glue sometimes. Could have potentially put too much flex on the RSX. Definitely at least put HEN on the console and see if the ps2_netemu (software emu) works via managunz

Turn off all options in the game tab under settings. A fully backwards compatible PS3 A series won't load a PS2 game if upscaling is turned on

This is BS information. I own both full and partial emulation PS3 models. Both run PS2 games just fine with the upscaling options turned on and hdmi output.
This sounds like you have an issue with your hardware.

It's not BS, it actually depends on your TV. When you turn on upscale it actually warns you of a blank screen and explains not all TVs support it. Thanks for the miss information though, we have already established its a hardware issue.
 
I have a CECHA00 and run into issues with the hardware PS2 games. I find that PAL games more often than not won't work if the HD upscaler is turned on. Also, the native ps2 mode seems very finicky and might freeze randomly if the fan is set to a custom speed via webman and the console is under 50 Celsius.

Set to say SYSCON and it's under 50? No problem.

40% fanspeed via webman and console under 50? You'll most likely get a freeze unless you go past 50 or ps2 mode is set to SYSCON.

My console has been de lidded with new thermal pads throughout and plays PS1, PS3 and emulated PS2 fine. Does anyone know of any solution or is this the downside of full PS2 hardware?
 
Computer Booter did a long investigation into the issue and hit a dead end. Ace Consoles in Australia did a frankenstian modification on a PS3 "A" revision that had blank screen issues when running PS2 games. After the mod.the PS2 wouldn't play due to region restrictions, this was strange as Evilnat was installed effectively making the console region free. After a.999 downgrade and back up to Rebug 4.84 the console was fine running all PS2 games. I currently have this issue and I'm pretty sure it's a problem with the RSX. It's not a major problem but enough for it not to send the PS2 signal to the digital synthesiser chip. Computer booter found that there was no.issue with the EE chip on the board he was investigating. This was determined by using a UART reader and Python to look at the bring up information when trying to load PS2 games. This highlighted no issues where found with the EE chip. So looking at the hours of work both CB have done and Ace Consoles I conclude that this is mostly a BGA RSX issue and a professional Reflow or RSX replacement is the answer to most of these PS2 blank screen issues

Quick update: I've found a partial solution to my problem that might help others. Going into webman settings and put the fan speed for PS2 emulator to 25% and the minimum speed to whatever you desire. Now start a PS2 game from disc and it won't freeze and the fan will stay at whatever speed you were on already. I'm still trying to figure out how to get the internal games to not freeze at low temps without low fan speed.

Atualização rápida: encontrei uma solução parcial para o meu problema que pode ajudar outras pessoas. Entre nas configurações do webman e coloque a velocidade do ventilador do emulador PS2 em 25% e a velocidade mínima no que você desejar. Agora comece um jogo de PS2 a partir do disco e ele não congelará e o ventilador permanecerá na velocidade em que você já estava. Ainda estou tentando descobrir como fazer com que os jogos internos não congelem em baixas temperaturas sem baixa velocidade do ventilador.

I had the same problem on my CECHA00 Frankie, if the temperature is below 60 the ps2 games freeze although it is possible to access the menu and return to xmb or restart the game... above 60 they run smoothly... considering that I live in Brazil temperatures above 60 degrees are easily achievable

never any reason to use 9.99 pup. just turn on qa flags and downgrade.

I was simply highlighting the process Ace Consoles did, whether its the best way to perform this process is neither here nor there.

i understand. i only mention it because 999 pups can brick 3.56 minver consoles. some users are not so careful as the pros.
 
So a slight update: After more testing the CELL temp seems to be the reason for the PS2 games running via the EE chip freezing at low temps. The RSX can be cold as you want but the CELL has to be at a minimum temp if you want to play PS2 games via HW BC.

Also, @Timbo9876 you probably already know this by now but PS2 games from PAL territories have a high chance of not displaying with the PS2 HD option turned on but NTSC aka 60hz Jap or USA games will always display in HD no problem. 1080p is something I recommend disabling on CECHA models as it just creates more wasted heat IMO. Native PS2 mode doesn't benefit either and is fine at 720p and the biggest PS3 games seem to be 720p anyway or have a crappy 1080p mode.

Thank you for the update, I just dealt with this issue on my Frankenstein CECHA, what a weird quirk. What's the recommended fan speed. It works well on SYSCON mode on the CFW but I don't like running the fans that low with PS2.
 
Is it safe to leave syscon as fan control? For me PS2 work only with this setting, at minimum 71 degrees CELL and without upscaller for PAL titles. My console is DEX forced to be CEX, DECHA-00A with retrofitted 40nm RSX.

it's probably okay. it's just meant as a precaution. I'm assuming sony tested the official ps2 classics to make sure none ran the system too hot by themselves. though, custom ps2 classics might make the system too hot on normal syscon. your temp is fine though. I might be concerned if it reached 80 degrees C, but it's about in line with an average system, maybe a little better actually. I remember mine would get to the 68 degree C temp threshold I had set within a few minutes of just waiting on the xmb. right now, I have a superslim plugged in, unhacked, and it's very quiet. you can hear it if there's no noise coming from the speakers, but most of the time you don't on normal syscon.

I had a discussion with al azif a while back regarding fan control, but it was about the fan of the ps4. we both agreed that it's at least fine as is, but of course, it's not isolated in case the system gets very hot like on the ps3. I'm not sure how they'd feel about that one as we never discussed the ps3, but imo, I think people are too concerned with temps. I might be for an early phat, but I think the cooling is good enough as not to be too out-of-control generally. I know sony and the rest opted for quieter systems, possibly for this very reason. I mean if someone noticed the system get very loud all-of-a-sudden, they might think there was a problem.
 
This is kind of weird, as long as CELL's temperature is higher than 71 degrees all ps2 games work (no matter with ot without upscalling) but then if temperature will drop under 71 it instantly freezes, and even then RSX cannot reach more than 60 degrees. So for now I set min temperature to 76 and I'm not sure how much % for ps2 to not damage console, I mean now I have 25% which is drastic so I won't go playing more than testing.

EDIT: No matter PAL/NTSC with or without upscalling, as long as CELL's temperature is high enough, all ps2 games work.

I'd say an actual PS2 would be preferable at those temps. Are your NEC tokens the stock ones or were they replaced?

Replaced, service that fixed this ps3 had a problem because initial replacement brought GLOD, after finding what caused it console works well but still for ps2_emu CELL needs to be above 71 degrees or else I have blank screen or game freezes (psbutton and exit to XMB works).
 
It's possible that the EE chip isn't getting enough power from the new tokens to work without a hitch. I've had my PS3 BC examined and it was found that the tokens used to replace the originals didn't have enough power to boot straight into PS2 without any issues below 40 but the power it WAS getting was close so it functions at 40 c as a result. Maybe yours is similar?

I'm honestly not sure, I would have to ask service what replacement they used. However, I sent them another A01 with similar issue (GLOD) so if ps2_emu will cause problem, I'll let them know it's probably too weak NEC/TOKINs. Thanks. :)
