我发现白板,至少在我的6750 ,360 上 原来插着电源 第2天也是能开的,不插电的话大概1小时后就开不了了,要几次后反复关,是几次,不是2次,本来想换电容试,手头没,又听论坛哪贴里说白板这问题无解, 本来死心了,就那样玩吧, 但看到了一贴 http://forums.xbox-scene.com/index.php?showtopic=738658 不要***的应该,看到这老外FIX 了,但也没连线实际图,有谁解释下他说的可行不?3.3 V 不要接也行? 下面那张是U52B 的点的图 ,老外自己在 XBOXHACKER 上说,有同样问题的中国白版的使用者, 用同样方法解决了, 另外有意思的是那里回贴的某同志,说把白板的短接点跳线,跳在 SLIM 那,他的冷起毛病就没有了。。。。。。 看到别的方法继续更新吧。
下面是老外REOLIN的话。。。引用下
From factory, white chips have pin 7 and 15 shorted - there is 1.35v (diodes are used to lower 3.3v to 1.35v or near it).
It's not the right thing to have 1.35v on both pins - you should have 1.8v on pin 15 and 1.1v on pin 7.
So I decided to fix it - I took 1.8 straight from the xbox board (U5B2 on my falcon) and connected it to the "-" of the middle diode (red square)(yes, it's "-", not "+" as it's printed on the board). Then I soldered the wire from the yellow square (1.8v) to pin 15 (lift this pin up - it should not be shorted with pin 7). If you do so, you will get ~1.2v on pin 7 (the third diode lowers 1.8v to 1.2v or so).
Don't connect 3.3v after this mod - the board can work without 3.3vStanby - you can read the "Cheap mod" thread on rgloader forums.
Also, reheat all components on the glitch board - cold solder can cause problems too.

Did i miss something here?? Ive read over his post several times and never once saw where he said he used that cpld. So which leads me to think that may not be his problem. Now if he IS infact using this cpld then you just got extremly lucky with you post.
Well, you can see "X360Glitch" in the title of that topic - the official name of those crappy white chineese chips. And the diagram is also for white board, so it's pretty strange you missed it
After all, I can't guarantee that my method will fix your problem, but you should definitely try. I posted it on other forums and several people fixed their problems after doing it.

DIODE 貌似是2级管的意思。。他说取 红筐里 2级管的 - ,这符号主板上有印,但还是小心操作,弄坏360 就不好了, 说不定有人说 白板跳SLIM 那还真有用。。。。。。不用改也说不定作者: libuyan 时间: 2011-12-18 16:22
1.8V找到了,就是红框中2个电解电容下的那个黑色稳压的原件,该元件悬空的那个脚就是1.8V。作者: libuyan 时间: 2011-12-18 16:24
就是U5B2这个原件的中间那个悬空的脚。作者: poska 时间: 2011-12-18 16:36
不用改···直接跳SLIM直接就有1.8V电压过去!作者: x-8232 时间: 2011-12-18 23:20
看到有朋友成功了。。。另外LS 说跳SLIM 的方法也行。。。 白板真的要解放了。。。。作者: hehaojing 时间: 2011-12-19 01:04 试过了,512的CB6751短接SILM那个跳线后无论冷机热机都是秒起!作者: x-8232 时间: 2011-12-19 01:07
