CR stopped flashing, now 0110

[marcusinteruptus]

Hi

I originally glitched this 360 in November for a mate and it has worked fine since then. He was made redundant about 2 weeks after so has had a LOT of use since then.

Last week he was playing a game and it froze, when he rebooted nothing it powered on but the coolrunner didn't flash green.

I've had a look at it, re-soldered the green wire as that did cause problems when I did the install. I've checked the continuity on the other points and they all check out.

I've reflashed the original nand from when I installed the coolrunner it and now RRODs with a secondary code of 0110.

I've searched and this seems to be a RAM problem and it needs reflowing, is there anything else to try?


Thanks

looks like the first one is bridging on that pad on the hanna chip

I've checked with the multimeter and there's no continuity between the pad and the wire, and the only point I've resolder since it stopped working is the green one.


The picture attached is from a different angle and shows it clearer.

0110 is either GPU or RAM. Start by putting pressure on each of the RAM bricks as you might be able to locate it (if it's indeed RAM).

If not, then a GPU reflow should sort it.

It's a Falcon, I've tried pressing the 2 chips either side of the copper heatsink pipe but it still RRODs - are they the RAM or are there more that I can try without taking the heat sinks off?

 

[Martin C]

If you have a spare CPU heatsink, put it in place of the GPU one. This will give you access to the other RAM blocks.

The only spares are on the other 360s kicking around. I'll get my mate to drop it in to Teajunkie for a repair.

Thanks for the help though Martin.

Are you using stock XCLAMPS or bolts? If using XCLAMPS try putting some bolts in there. 0110 can be tricky if it's ram but it could be GPU too.

Also may want to test the GPU ohms to see if you get a reading. If a GPU solder joint is detached you may not get a reading at all. Set MM to 200 and test at the resistor in the attached image. You want a reading above 1.0 on HDMI units.
