Monitor wont light up. the power light only flashes on and off continuosly, even when trying to shut it off. It's a dell e173fpb monitor.

Hi there! You can test first if the monitor is working. Disconnect it from the computer then turn it on after that it should show you colors on the screen this means its working if not then its no use trying it on a different computer.


Hope this helps!

Hello,

The flashing light on the Dell E173 series indicates a failure in the power supply board. This series has several versions on the board so you will need to know the exact model, it is listed on the label at the bottom of the back cover. The versions are E173FPc, E173FPb and E173FPf. We have repair instructions posted on our web site at: http://www.ccl-la.com/blog/index.php/category/monitor-repair/dell-monitor-repair/ that cover each version on the unit. The repairs will require replacing a few pars that will need to be soldered.


I hope this helps, if so please rate our solution.

More likely to have problems in the inverter circuits. Need to check the transistors, caps, fuse, and solder joints. Please see what goes wrong with Dell monitors here to get some ideas for what to look for:

Most common failure in this model is shorted transistors in the inverter circuits caused by poor solder connections, see pictures here for guide: http://s807.photobucket.com/albums/yy352/budm/Dell%20E173FPb/

The flashing is an error code. Call Dell Tech support & they can tell you the exact problem. Hope this helps.

These models are prone to shorting of the inverter drive transistors, 2sc5707. An in-circuit ohm meter test will reveal which are shorted if any. They should be replaced in pairs even if only one is shorted. Bad solder joints on the transformer can cause them to short so look for bad solder.

Hello,

Based on what you have stated your Dell monitor is dead. Seek support/replacement under warranty. If you purchase this with a credit card you have a double warranty through your credit card. You'll have to suffer through Dell's phone support to allow them to troubleshoot your dead monitor but be patient and a new or newer model will be on its way to you soon.

Hope this helped you and fixed your dilemma.
