Question about Dell E172FP 17" LCD Flat Panel Monitor
I have a dell e172fp 17 inch . suddenly when I tried to wake it up from power saver mode, it flashed a second and went blank. it keeps blinking green light on the power button. the monitor blinks white once in a while. when i press the power button hard, it shows the screen once. Does anyone know what is the reason for this problem ?
I buy and sell these monitors (Dell E17FP) the problem is with the transisters (Q739, Q740, Q759, Q760) they short out and the monitor will just blink on and off. You have to desolder them and test them with a simple battery and light circuit. The reason they blow is because of the dirty solder joints by the transformers. If only on pair of backlights work the problem maybe transisters Q751, Q743. I home this answers your questions.

I bought the parts (6 transistors, 1 fuse) on ebay (http://cgi.ebay.com/DELL-REPAIR-KIT-E152FP-E153FP-E172FP-E173FP-E173FPB-/220488756040) and put them in. On the ebay site it also says make sure to resolder the transformer joints. When I turned on the monitor the color bar screen appeared in the bottom left corner for about 3 seconds and then disappeared. Then the power on LED started blinking again - back to the original problem. I'm going to attempt to resolder the joints. Any more suggestions from anyone with experience fixing the problem?

I bought a new acer 19" . i will try to change the capacitors and see how it works. if not, i will try the power inverter option. but my new lcd itself cost me 100$ after rebate. so paying 70 pounds for an inverter is unwise. previous poster, I am sure it is problem with monitor and not the connector coz it doesn't do the self diagnosis. thanks for all the responses so far.

Hi, I belong to another group, and posted this same question, due to an E172FP that I bought knowing it was faulty. The person who answered my post stated that he had just been doing a study on this because of a customer. Apparently it is quite common with this model. The monitor is made by samsung and is good so I'm told, but the electronics is made by another company and this is prone to failure. The part in particular, according to the respondant, is the power inverter and he believes it could cost as much as £70. I have seen some inverters on ebay going very cheap. I hope the info may help.

Hi,other than suggest that you bring bring it to a qualified service personnel, the problem is might be too techincal and is inside the LCD monitor itself. Just to be sure, check that all the plugs and connectors going to the monitor are tight and secured. Wiggle it just a bit to make sure all the pins are seated. But then again, might it be your PC (video out). Try shutting down, reboot/restart. If this still doesn't work, try restarting in safemode (press F8) while booting, then start again in normal mode. If still no go, guess you're back to the first paragraph. Good luck. Hope this be of some help to you. Pls post again how things turn up.
