There are two possibilities, one is bad caps in the power supply, number two is shorted out transistors (P/N c5706/5707) in the inverter circuits. Please open it up and report back what you see so we can guide you further, see example fo failed monitors due to bad caps, lamps, etc: http://s807.photobucket.com/home/budm/allalbums

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

Dell E172FPb screen blinking


Hello,

If you've tested turning the monitor on without the VGA cable and it's still blinking I'd say there's a problem with one of the capacitors on the power supply card on your screen, when you're able to check it would you mind telling me the brand / reference of it ?
