Answers :

Willie114, You have typical problem of lcd monitor failure. There is only one further test you can do. Reconnect H170L to an already fully booted pc with WIN-Desktop showing. then and only then turn on H170L. As soon as screen goes to BLACK, shine bright flashlight 1 -2 inches from screen at different angles. You may or may not see the desktop screen even though the screen is black. If desktop can be seen it only means that the power supply is still powering up the digital lcd driver board. The problem is that your long, thin, Cold-Cathode-Fluorescent-Tubes are not lighting up due to a problem with the Inverter Supply that feeds AC to power the lamps. The inverter gets DC from the Switch-Mode-Power-Supply. The technology your are dealing with is similar to the new energy saving curlieQ screw-in replacement light bulbs. Only your tubes are straight and hung left to right horizontally in back of the lcd and their power source is a bit simpler and called a converter. AC to AC. Get back to me and I will let you know of your options as a consumer/user whose screen has gone to BLACK. I'm louie12fix on fixya or lmistyrel@ aol.com Bye for now
