How do I open the case on a Dell E`73FP? I have purchased a new logic board for it but have been unable to open the case for installation..I have begun popping the edges but this sounds and looks like it is stressing the plastic. is there another way?
I am repairing my E173FPc Dell Monitor and to take off the back cover you must look on edge of frame to the lcd and you will see little Pry Slots.
Get a flat head or knife and stick it in there, then give it a twist and "snap!!"..continue along the frame at about 4 inches apart till the whole frame is off (but dont take the frame off just yet.
lay the panel down on the LCD on a Towel or somthing soft, then unscrew the 4 phillips screws to the stand and remove. then pull the back off.
Now on the sides of the tin you will see 4 more screws,...remove and lift but be carful you must unplug about 7 plugs before you can get to take out the circut board but that has screws also that need removing.(((seperate and label your screws)))) or (((take a few digital Photos as you go)))).. THATS IT.. I WILL POST PHOTOS SOON SOMEWHERE THAT GOOGLE WILL PICK UP LABLED DELL E173FPc LCD Monitor repair Blank screen blinking green light specific>

Solid white meas the T-CON board is not getting the signals or 5vdc feeding it from the logic board or it has blown fuse.
Check all the caps in the power supply and on the logic board first, be warning, this case is real hard to open and MUST BE REAL CAREFULE WHEN SEPARATING THE FRONT BEZEL FOR THE BACK CASE! http://s807.photobucket.com/albums/yy352/budm/Gateway%20FPD2275W/
Look for loose connection between the LCD panel T-CON board and the logic board first, it may also have lost the 5vdc for the T-CON board. If you are going to DIY and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net Capacitors kit: http://lcdalternatives.auctivacommerce.com/
stand can be removed by hands because it has locks and you can remove cover by screwdrivers if not opened by screwdriver then look the locks and insert the screw driver in the gap lock can be opened then you can see smps and logic board
Buy a new monitor!! Seriously, unless you're the techie type that likes to tear open electronic equipment to see how it works and/or fix it, you're better off buying a new monitor especially if this old monitor of your's is a LCD.
You need to check the voltages first, on the electrolytic caps in thepower supply section with voltage rating from 10~16vdc should have 5vdc on the two legs of the cap, this 5vdc is used for the logic board. The other caps with voltage rating of 25~35vdc should have about 12~18vdc on it's two legs. That is the starting point, these DC voltages are in the secondary side of the power supply, be careful on the HOTside of the power supply, it has high voltage about 160vdc and 120vac which can kill you, so be careful. If you can post pictures, it will help. See example of my pictures here: http://s807.photobucket.com/home/budm/allalbums
Remove the base by the button release or 4 screws on the back. On the bottom of the monitor near the corners you will find two thin slots where you can insert a thin wide blade screwdriver or pry tool. Very gently pry the back from the bezel toward the center from both of these slots until the bottom is seperated, then contilue from the slots around the corners and up the sides until you have seperated the entire back from the bezel. Lay the monitor on the bezel and remove the back ( do not try to remove the bezel, at least not yet). Lift the tape that secures the ribbon cable from the bezel buttons to the logic board. Unplug the ribbon cable from the logic board by pulling on the connector (not the cable). Remove the cable covers from the back of the case (one has a screw, the other has a lift tab) and disconnect the lamp connectors and ribbon cable connectors (do not pull on the wires). remove four screws and lift the metal back from the screen.
OK. Start by remiving the cover, fan, adaptor card and power supply. Remove from the logic board: The hard drive power cable, hard drive data cable and the floppy drive cable. with the rear of the case facing you, release the two tabs with your forefingers while at the same time as pushing on the 120-pin connector with your right thumb. Slide the logic board to the front of the case until it stops. Caution: Be sure the power on/off button
clears the rear panel before you lift the logic board out of the case.
While lifting the board, do not touch connector
J19 or J20. (The oil from your skin harms
Gently lift the board out of the case.
Replacement Note: Remove the SIMMs from the
defective logic board and install them on the
replacement logic board.
I really hope this helps because it is correct information. If you want to be extra cautious, visit a repair shop instead. Good Luck!
