Power light blinks on and off. Picture comes up for one second on power up then screen goes black. Since repairs cost so much and probably have to replace anyway, thought we'd try to open and look around. How do we open and what do we look for?

Disconnect the display from the Computer and remove its power plug. While the display is turned off, press and hold the power button for 30 seconds. After two minutes connect the power cord and the display cord to the Computer and the power source and turn it ON.
If the power indicator on the display keeps blinking, then it's required to open it up to repair it.
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.
