| Here we have a non functional Dell 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. You will need to unplug the 4 backlight connections (connectors with pink and white leads, circled in red) and the control panel cable the flat signal cable. Then remove the 2 screws from each end, then undo the 2 small nuts holding the vga connector to the case (circled in yellow). |

| Before you fully remove the shield and board assembly be
sure to unplug the LCD signal cable that is under the boards as
seen in the picture to the right. Now turn the assembly
over and remove the 5 screws and the 2 plastic standoff clips as
marked by the yellow circles below. Now with the board removed
you will need to replaced the components that are circled. The
parts are as follows: 3 Amp Fuse (yellow) Q759, Q760, Q734 & Q740 - C5707 transistors (red) Q743 & Q751 - MOSFET Transistors (blue) The location number are for a E173FPb but the E172FPb boards have the components in the same locations. |

| 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. |
