Screen keeps on turning black, even though the power light is still on

The set has a problem that is likely power related===consider having a shop or a tech look at it---cannot wish it away, someone will have to open and check things to even have a chance to fix this.

Try holding the power button and then the home down and dont let go until after the screen goes black. that is another way to reset it

I suggest to open your computer and unplug your power supply and look for the color green and black cord which plugged from your motherboard. Then find a piece of wire and short the color green and black wire to test if your power supply is working and plug to your power socket. And check your electronic parts (capacitor) near at your processor, it might your capacitor blown out.

have you got any external monitor? please try with the external montior to be sure. if you have a view something wrong wtih the lcd.

First open the Data cable (From AD card to Panel).If light comes means Inverter card is ok and AD card is bad..If not means Inverter card is bad and AD card is ok..If you want to repair the inverter card,pls replace all the Electrolytic capacitor and Enjoy..

try with another cable, pc if nothing. need to get service.

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

This is probably a back light problem. Take a bright flashlight and while the monitor is on, point it at the LCD and try different angles, etc. If you can see an image, it is the back light, probably the back light voltage converter unit in the lcd. It could also be the back light bulbs.

If you don't see an image with the flash light, then it could be the main logic board.

Remove the memory from your unit - power it up it should beep if full communication is still happening across your m/board. No beeps you board has died. if it beeps and your using two diffent memory modules just fitt one leave the battery out and power it up = if no display pull power swap out the memory and try again. if display occurrs you have a defective memory module - throw that failed unit away
