我们有一个N5230A-4端口,可正常运行,但内部显示器出现故障。
(下半部外部显示器上的原始显示失真工作正常)我在7月校准了这个单元,没有看到其他问题。 技术人员现场订购了精确的OEM显示模块并更换了它。 (Sharp LQ084V1DG22,如原件所示)分析仪现在处于启动失败状态,并在此过程中发出4声蜂鸣声。 粗略故障排除表示CPU故障。 任何想法我应该指向他的方向? 谢谢你,Randy编辑:rmax于2014年11月19日上午8:04 以上来自于谷歌翻译 以下为原文 We have an N5230A-4 port that operated correctly but had an internal display failure. (Original display was distorted on lower half-external monitor worked fine) I calibrated this unit in July and saw no other issues. The technician onsite ordered the exact OEM display module and replaced it. (Sharp LQ084V1DG22 as indicated on original) The analyzer is now in a state of boot up failure and issues 4 beeps in the process. Coarse trouble shooting indicates a CPU failure. Any ideas what direction I should point him in? Thank you, Randy Edited by: rmax on Nov 19, 2014 8:04 AM |

当显示器被替换时,CPU会失败似乎非常巧合。
如果您完全断开前面板接口电缆,它是否仍会发出蜂鸣声? 如果取下FP电缆消除了蜂鸣声,那么它不是CPU。 这是什么CPU?... 500MHz或1.1 GHz? 请参阅http://na.support.keysight.com/pna/cputype.html。一旦我知道CPU类型,我将尝试找到4声嘟嘟声的含义。 它们是均匀间隔的哔哔声吗? 你现在在哪里? 以上来自于谷歌翻译 以下为原文 It seems awfully coincidental that the CPU would fail just when the display was replaced. If you completely disconnect the front panel interface cable, does it still beep? If removing the FP cable eliminates the beeps, then it is not the CPU. And what CPU is this?...the 500MHz or 1.1 GHz? See http://na.support.keysight.com/pna/cputype.html Once I know the CPU type, I will try to find the meaning of the 4 beeps. Are they evenly spaced beeps? Where are you located? |

胡bbs2 发表于 2018-11-19 12:34 我在宾夕法尼亚州。 分析仪位于佛罗里达州的一个设计中心,因此我正在远程协助。 处理器为1.1 GHz。 我让他断开了前面板,没有发出哔哔声但是我担心扬声器可能位于那里,这可能会产生误导。 如果他仅断开视频线路,则仍然存在蜂鸣声并且蜂鸣声均匀分布。 谢谢 以上来自于谷歌翻译 以下为原文 I am in Pennsylvania. The analyzer is at one of our design centers in Florida so I am assisting remotely. The processor is 1.1 GHz. I had him disconnect the front panel and there was no beeping however I'm concerned the speakers may be located there and it could be misleading. If he disconnects just the video lines the beeping is still present and the beeps are evenly spaced. Thanks |

哦是的...我忘记了扬声器的位置。 我知道我们已经看到安装了SODIMM RAM模块的一些问题。 如果哔声代码表明,那么至少修复是非常微不足道的。 待我寻找哔声代码时待机。 以上来自于谷歌翻译 以下为原文 Oh yeah...I forgot about the speaker location. I do know we have seen some issues with SODIMM RAM module installed. If the beep code indicates that, then at least the repair is pretty trivial. Standby while I look for the beep codes. |

胡bbs2 发表于 2018-11-19 13:06 为了解决这个问题,并为随后的搜索提供信息,我发送了一个新的1GB RAM SODIMM,解决了这个问题。 我们遇到了一批这些RAM模块的问题。 以上来自于谷歌翻译 以下为原文 Just to close out this issue and to provide information for any subsequent searches, I sent a new 1GB RAM SODIMM and that solved this problem. We have had a few issues with a batch of these RAM modules. |
