Update: I tried the comaconsole repair yet it still has the same issues, unless the BIOS chip is bad which it would need a modchip. I'll give that a go. If that does nothing, it may just be a board for parts. GPU/CPU get warm as they normally would.

Have you removed the D0 grounding point under the motherboard? D0 grounded without a chip causes the system to FRAG.
I'd assume the same if the LFRAME trace has been cut.

Has the metal cage got rust on it?
It does have rust/patina all around the shield but nothing indicating any sort of spillage. It's a sticky substance only on the board. I'll give it a thorough clean and run the system again and report back.
With the yellow box, it's a copper layer that darker spot.

I get no video or sound with the ODD/HDD disconnected, also the same when they're connected. I've checked the rails just now
Blue: 3.3V
White: 3.27
Brown: 3.28
Orange: 3.3
Red: 5.0V
Yellow: 11.63
Within the 10% range but the 12V rail is a little low. Here's the board also.

I recently bought a few faulty Xboxes yesterday and I want to try sort out this 1.1 which FRAGs. When I press eject it will often not open the disc tray, sometimes it will open quarter or half way or not close when it does open. I've tried 3 disc drives and they all have the same issue indicating a motherboard or possibly daughterboard problem. I have removed the clock capacitor which was only starting to leak. I've cleaned up what little leakage there was.
Any ideas?

I just can not understand how all three of those 6.3v 3300uF ones adjacent the CPU heat-sink blew at the same time and no others anywhere else on the MB looking even slightly suspect. If the Xbox had been well used then it might be understandable but, as said, this one has been deliberately cotton-wooled over the years because it is a more valuable LE Green.
Bad batch of caps?
Definitely a bad batch. Those 3300uf are the Nichicon HM series which were used in many computers from around 2002-2006 I believe. They all go bad yet others stay fine.

I think it's still going bad. I've seen a few which have visible rot yet displayed no symptoms (I still trace repair them!), and one with no visible rot yet still developed the symptoms.

The top left pin on this close up image has sunken in completely.

Philips behave no differently whether soft or hard mod. They do seem to have a habit of failing completely and that causing boot problems more often than others.
I know this for a fact. I had one die on me recently https://www.youtube.com/watch?v=pqdMb6xT8cI

Does it happen during a game? Maybe try unplug and put back the video connector as it may be slightly loose.

2) when I turned the console on, there was still a burned electronic smell, that makes me worry (it dissipates a couple seconds after I turn it off). IS it safe for me to measure the voltages meanwhile? I mean, could something explode suddenly if there is a short??
Is it possible to test with it open? You could see what's going on or where the smell is coming from.

Mainboards can't damage a PSU except in very exceptional circumstances.
It's hard to say what went on in there other than it was under some stress for a while but, that could be just from years of use. I'm sure if you hooked that blown out capacitor in an ESR tester, it would read very high (should read no more than around 5 ohm if good.)
-
I tend to flow a small amount of new solder with my iron into the solder joint but keep the old solder there too.
-
Interesting. The capacitor installation looks fine.
I'd start with gently applying pressure around the video connector left/right and up and down and see if you see any changes on screen. Then move the video connector around. Have a look inside the video port and the cable end (what goes into the Xbox) for anything unusual like a bent pin or dirt/dust. The Microsoft cables fray quite easily also.

The yellow wire will push done and be ok try heating the other side of the connector ( the white part) with a hair dryer until it's warm to touch and make sure you hold all of the wires tightly.

As a last resort, you can remove the power supply at the same time as the motherboard so you don't need to unplug the connector.
I too don't like the 1.0-1.1 Xbox revision power supplies due to the difficulty in removing them.

What the....wait, is this why I can't for the life of me remove that connector from the motherboard? It seems to be stuck on.
To me that image looks like a 1.0-1.1. Those power connectors are incredibly hard to get off. At times I feel like I was going to damage the motherboard. I try to hold the board very close to the power socket and pull (hard) the power connector on one end. From there it gets easier.
On both of the supplies it looks like there's dry/cracked joints all around. Where you see a line, especially a ring forming somewhere around the joint (see second pic).
Reflow whatever looks bad and we can go from there. -

do u think that will help?
It did help for me so I guess that's where the problem lies.

What you'll want to do is use another disc drive and mod your system so you can bypass the disc drive altogether.
If you can't get another drive, you could adjust the laser intensity potentiometer, but that is only a short term option for either softmodding or modchipping your system. You will need a multimeter for adjusting the pot.
-
I'm not confident enough to remove the components and put them back on a good board. I do have a FRAGing board (1.2 or 1.3) that I will sacrifice if it has the same capacitors. I'll come back to this post in a while when I get to it.
-
I think you'll need a crossover cable or adapter. The adapters are around $5 (my local currency) from eBay.

I just checked the last component. The times C6T6 read anything it ranged from approximately 1500nF to 6700nF. Hardly an accurate reading. 90% of the time it didn't read anything. I guess that's because it's in circuit.

I just noticed a few SMT caps missing from the underside of the motherboard. They are C6V1, C6V2 & C6T6 (circled in red in the image attached). Could anyone give me the values for these caps? This is a 1.0 Xbox.

Hi, I checked C6V1 and C6v2 on a 1.1 Xbox.
I measured 63 picofarads for each using my LCR-T4 component tester. The C6T6 I couldn't get any measurement for some reason. I'll go back and post here if I manage to sort it.
I tested in circuit, chances are that testing in circuit will affect the outcome compared with testing components individually. -

I would try the faulty DVD drive and see it it boots past the error 11.
If it does then swap the boards.
I tested the disc drive that wouldn't read. The console booted fine aside from not reading discs. It was definitely the mainboard causing the fault. I've since swapped the board from the weak laser one into the drive which had that unusual issue and all is well.
Thank you!
-
Interesting. The console cannot find the disc drive as well as that issue with the lens actuator bobbing up and down frantically. I'll assume the drive is completely toast. Perhaps the lens (assuming that's still working) can be pulled and used in another Philips drive at least. I've got another one which has a weak laser.

I've had this v1.1 console for a few years, it's been sitting in storage for 3 years. I decided to power it up to see if it's still running only to find I get this weird lens issue with an error code 11 on screen. I've also tried the disc drive on my main console, the same thing happens. Would anyone know why?
I've got another GDR-8163B that's already been modified for use on the Xbox. I'll use it and modchip the system.

Do xbox capacitors ever need to be reformed?
in General Xbox Discussion
Posted · Edited by Lina_Inverse_
The Nichicon HM series near the heatsink on some revisions (I believe only 1.4 but that's all I've seen) fail as they can bulge and lose capacitance without power applied. I've had two consoles bulge, when I put them away, the capacitors were fine. It's only because they're a bad batch. On an LCR meter I believe all 3300uF caps read around 10-20uF which is very bad but ESR was within normal range. It prevented powering of the consoles whereas both were working fine before. It could be the warm environment I stored them in?
Aside from that, I don't think there's much of an issue. I've got electrolytics that are much older (1970s) in equipment such as my main amplifier still working well within spec, or close enough that it's not an issue.
