  problem solved, R6 150k of the fan control board is broken.

thanks

我有一个非常相似的问题。
电源指示灯亮起但按下电源按钮时无法启动。
但有时它会正常运行。
当我每天切换它时，我不能让这个套件像这样运行。
我有第二个单位根本不会做任何事情。
现在电源灯显示出来。
它刚刚死了。
任何人都可以帮我找到这个错吗？

  I have the a very similar problem. The power light is on but will not start when pressing the power on button. But sometimes it will then will run normally.
I can't have this bit of kit running like this it has to run when I switch it every day.
I have a second unit that will not do anything at all. Now power light showing at all. it's just died.
Can anyone help my find this fault?

大家好。花了一点时间，我终于让单位再次工作了。
它有三个问题。
1在电源上缺少待机电压。
是Mosfet所以改变了。
第二个是风扇控制PCB，在看了之后我发现一个100K电阻器的价值已经很高，而且连接器非常脏，所以它被清理干净，现在工作正常。
第三个是参考板，其中一个钽电容器有goneshort电路。
那是替换，现在该单位正在通过所有这些内部测试，没有报告任何问题。
只需要清理它并重新投入使用。
感谢所有人对我这个单位的帮助。

  Hi all After spending a bit of time on this I have at last got the unit working again.
It had three problems. 1 on the power supply where the standby voltage was missing. The was the Mosfet so that was changed. The 2nd was the fan control PCB where after looking at the I found that one 100K resistor had gone high in value plus the connector that was very dirty so that was cleaned and now that is working correctly. The third was in the reference board where one of the tantalum capacitor had gone short circuit. That was replace and now the unit is passing all this internal tests with out any problems being reported.
Just got to clean it all up and put it back into service.
thanks to all how helped me on this unit.
