Hi, had a question about what you said, have a minute?

Hey there, Im fairly new at and dont know if its correct of me to just ask you directly for a little help. You hae talked about the problem i have in one of your posts. If you have time can you please help me answer this question.

I have a Dell wd4200hd which the same as Sanyo dp42746. My Y main board makes a little whine at first then same tone. The screen just went black. I disconnected the ymain from power and the tone went away, but the screen is still black. Do you think that I have more issues than the Y boards?
The ymain board model is SAMSUNG LJ92-01200A LJ41-02759A Y-MAIN

You need to replace the top and bottom y buffers when you replace the Ymain. If not, it will just go back out. If you have space, wire a 12 volt mini cpu fan near the left of the Ymain and the buffers, should last alot longer that way.

Hi again,

Appreciate the direct "Ask Me" and the repeat use of FixYa.

Interesting concern, should be pretty straightforward. Anyways, pls try to:
  • update/re-install the driver from Microsoft Download page;
  • alternately, disable the "Allow the computer to turn off..." in the Power Management tab of the USB Root Hub Properties in your Device Manager.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you again for using FixYa.
