Having problems with your Dell E172FP 17" LCD Flat Panel Monitor ?

Press power on... screen flashes on (blink), then goes blank and power button flashes


Answers :

Dpelrod727, Yes, the "switch-mode-power-supply" is in "partial" or "full" SHUTDOWN mode. Reconnect E172FP to a fully booted KNOWN good PC with the win-desktop as the displayed screen. Check with flashlight to see if your LCD panel is both BLACK and BLANK, or just BLACK by holding a bright flashlight 1" from screen at different angles even though the screen appears to be blank. If very faint image of desktop is seen then your SMPS is still half alive. Here are your options in either case. 1. Trade in for new. 2. Try Dell for a cash+old swapout for a Refurbed unit. 3. Check out www.ccl-la.com/badcaps, www.badcaps.net, www.lcdparts.net, and YOUTUBE long video clips dealing with LCD monitor disassembly and LCD repair. could be helpful in making decision on what to do.

Typical problem with this model is the failure of the transistors (2SC5707/5706) in inverter circuits, they shorted out.
