Here we have a non functional Dell E172FPc 17″ LCD monitor. This one has a blinking power light and no display.First you need to remove the power cable, signal cable and the stand. To remove the stand remove the 4 screws as shown in the picture to the right. After the stand is off the signal cable can just be unscrewed.After the stand is removed you will need to pry the back of the case off as illustrated in the pictures below. Use a small flat bladed screwdriver start at one of the release openings on the bottom as shown. Once you have a little gap in the case just pull the 2 halves apart and work your way around the screen.
After the screen unit is removed from the plastic case we can get down to the repair. We need to remove the power supply unit. First remove the 2 metal shields as shown.You will need to unplug the 4 backlight connections (connectors with pink and blue leads, circled in yellow) and the control panel cable the flat signal cable. Then remove the 2 screws from each end. You will also have to unscrew the vga connector and power socket.After the metal shield and electronics are removed from the LCD panel you can remove the 5 screws that hold the power supply/inverter board in place. Carefully remove the board from the shield and unplug the cable that connects the power board to the video driver board.With the power board out you can see the parts that will need to be replaced. The 6 capacitors that you need to replace are circled in yellow on the picture to the right. You will need to be careful when inserting the new capacitors into the board and put the negative stripe on the side of the cap going the same way as the old one faced. Unsolder the old caps and solder in the new ones, reassemble the monitor and test.After the parts are replaced just reverse the procedure to reassemble the case. Now apply power and you should have a fully functional monitor again.
