The light and screen flash as it cannot sense a video signal from your computer and so it will not switch on fully or goes into shut down/sand by mode.

The power light on our model E172FPb Dell monitor is blinking. The screen does not turn on. What could be the problem


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

You need to open it up and inspect the componente inside, look at the fuse and the transistors in the inverter circuits first, also look for sign of over heating on the board, see pictures here for the guide: http://s807.photobucket.com/home/budm/allalbums

I have a Dell E172fPB LCD Monitor that comes on and I can see my desktop for a split second then the green light flashes about once a second or two, and the screen flashes very briefly with the green power...


phil_bischof, Not many sub's for it!! Because the package not standard "TO220AB" It is TO220FP package device. You can try www.digikey.com for this part number: MBRF20200CTGOS-ND and ask them if you really need to buy 10 of them for $27.88 or will they sell you only 1 for $2.80 + shipping? Have you determined cause of rectifier failure? Good luck, guy. 12fixlouie
