Microphone hissing sound
That sounds alot like the microphone booster in control panel. Depending on what version of windows your are using, you can just open the sound control from the taskbar and go to the advanced settings and uncheck the setting "microphone booster". Adjust microhpone volume accordingly.

How do i reset my yamaha dx 100 back to original factory settings
yamaha dx100 reset. Press voice switches 1 and 2 while turning power switch on. Display will say test entry?. press the plus/yes button. This will reinitialize all memory to factory settings. Also the lithium ram backup battery voltage will be displayed as check level with a number representing the battery voltage. The number will be 10 times the actual battery voltage. A new battery will display 33 representing 3.3 volts. If your reading is below 22 then your battery is shot and will need replacing and if you turn the unit off it will probably get a scrambled memory again.

Tyros 1 cutting out screen goes grey and restarts
Guessing that some people think a Tyros 1 is a PC or something.
If the Tyros goes blank screen and all the lights go out then it is most likely the REG board (regulators) that provide the 5v and 3.3v. This overheats and the devices shutdown. Quite often this is cured with a restart on more serious cases the regulators need replacing. As they are cheep it is best to replace all while the unit is apart. I am just about to do this repair on a Tyros I purchased the other day.
