Ps3 shows red light then turns completely off when I try to turn it on.

[Gramsone]

I have an interesting issue, Whenever I go to turn on my ps3 it turns off almost instantly. You can see the green light but then it turns off. No red light, nothing. Its just completely dead for 20 - 30 minutes, then I can turn it on once again and the whole same thing happens. This ps3 has had the NEC/TOKIN caps by the cell replaced by me. Another important detail to add is the caps I first added blew up because I did not short the ends(Doofus Me). When I syscon'd the board the only issue was power to the cell itself. I'm writing this in the hopes I can diagnose what's going on with help from PSX Place.

It's likely a short on the 12V rail. Try a multimeter probe big MLCC caps for short, especially ones under RSX and Cell.

I ended up finding out the issue was a buck converter. The buck converter made a short and caused it to turn off when powered. I had some donor boards I used to replace it and it turns on. Only thing now is, the dreaded GLOD occurs. I've done this replacement on two other consoles and have gotten GLOD. Is it something wrong I'm doing or is the GLOD unrelated?

GLOD is unlikely related to shorted buck converter. If anything seriously power related, syscon will not allow the system to boot, hence YLOD. AFAIK GLOD is more about RSX(BGA, bumper) and HDMI chip(faulty, not soldered properly, wrong type of chips), the EMI filter(faulty, discontinuity) to the HDMI connector or anything in between them.

But why you replace the buck converters on the other consoles in the first place, I assume they haven't got the same instant off issue?

Well I mean to say that GLOD occurs instead of YLOD. I noticed the capacitors near the buck converters were shorting, so I took the buck converters off until I found the short. First one I took off had the short so I just took one buck converter from another board to fix it. Before I fully replaced the NEC/TOKINS, syscon gave errors indicating power issues to both RSX and CELL. Which is odd, considering that I was only receiving syscon error 1001 before hand. Now each chip has power issues after the capacitors exploded? Now GLOD is all that occurs, but I will see if the HDMI chip has anything to do with it, If not then I know what the answer is sadly.

Thanks again for the help.

I don't quite get the repair procedure. But here's what I understand: 1001, 1002 error only happens when TOKINS are bad, because the ripples of the regulated 1.2V voltage is too strong to keep those chips running. If you have shorted capacitors or buck converter or power mosfet (not degenerated caps) around 12V rails it's more likely 3000-3004 errors or instant off to red light, because there's no way that PSU can keep feeding the console that voltage. Those are errors all detectable from syscon. Now GLOD is something that undetectable by the syscon, so everything seems working properly but the video output is wrong. RSX-HDMI IC-HDMI connector is more likely. One thing to note, probably you already tried, is to reset PS3 to see if the video output goes back to normal. Or try the AV multi out before a HDMI IC surgery.

Yea I have tried holding down the power button, but I cant reset video settings. The green light stays but nothing shows up on hdmi, I will have to try av just to be thorough, though I expect the same result. One question about HDMI IC though, If it is bad, I assume that resetting video settings wont work and I wont hear two beeps? Or If its just the HDMI IC, I can still hear two beeps but nothing shows on the screen.

Thanks.

I haven't got a bad HDMI console at hand but I believe you'll still hear two beeps(to reset video or to enter recovery mode) but due to the HDMI is broken you won't see images. Try av multi out cable can isolate the HDMI only issue from other faulty. If av multi out is normal, you can further test the hdmi if you got this https://www.psx-place.com/threads/problems-with-hdmi-display.29590/#post-343568 which is proved to be very useful to me.

Hm, sounds like its going to be a bga problem sadly, even though it never threw 3034's. But Ill have to try this out once I get home, I do in fact have that HDMI Device, so ill have to learn how to use it for further testing.

Thanks for all the help.​

Update:

Tested out AV but no video output. I'm sadly going to have to use this board for parts If I cant find anything else that could be wrong.
Once again I appreciate the help throughout this thread.
