Just tried what Willhelm said and no luck whatsoever. Out of all the 360s I've fixed, this one is just refusing to work. Maybe I'm just not putting enough pressure on the other RAM chips, I dunno, I've screwed everything down with two pennies. Nothing. Tried it with three pennies. Nothing. Three pennies stand about 1cm, so I've a feeling if I had another penny I'm going to do some damage.
Something interesting that I noticed which may or may not be helping this error is a slight chip taken out of the second RAM chip, which I will demonstrate with this funny looking MSPaint image.
http://img149.images...=ramchipjb9.pngI'm no electrician, so I'm not sure if there's a shell around the actual chip or not.
I'm at an end... any more ideas? =/
Electricians fix power-points and wire light-switches, they wouldn't have a clue (niether do most electronic technicians these days, fixing game-consoles is a very specialised area and most aren't willing to take the large amount of time to gain XP and learn, especially for such little pay)
That said: 0020 I have heard/read somewhere that this is the consoles way of telling you to stick it! (it can't detect what the issue is, I think it's possibly general low CPU or GPU power error) I think that's about right however in my XP It usually relates to two things: 1. Bridged Solder under GPU (Bad news, needs re-balling not often worth the effort these days) 2. Power issue (Check ur MOSFETs - If u know how, should really be done with a CRO ideally, can be done by desoldering with MM, but given their low-heat tolerance, it's often difficult to tell if u killed it on removal, many of their temp specs suggest they can be damaged before the solder melts!!) ALSO: Check ur Caps
3. If it's a Xenon and not a JTAG (or JTAG-able) then re-cycle it (this issue seems worse with Xenons, I haven't taken the time to find-out exactly what it is, but there seems to be a type of Xenon that will get this <usually after some noob removing the X-Clamp or some other dodgy internet 'fix'> Suffice to say it always coincides with torn warranty stickers or warranty stickers of those who should not be let near game-consoles
My advice: Take it to a professional and suggest they check the power system (MOSFETS and CAPS) after removing any dodgy RROD 'fix' crap and giving it a professional reflow. If ur lucky, they might have an X-Ray setup and can check the CPU and GPU properly.
Going by ur history: I would guess that where the RAM connects under the GPU is possibly shorted or open, if you did a very slow reflow (with proper equipment) of the GPU, (if that fails and ur still keen, GPU,RAM and CPU - the CPU especially if it's a Xenon) Paying special attention to mobo warping and prevention therof.
Hope this helps somebody.... Peace
