Disassembly of case

I need to remove the inverter to send it off for repair. I've removed the monitor's base (stand) and the screws around the back of the case but the case won't pull apart. I believe there are hidden clips around the edge. How do I locate and release them without breaking them or marring the plastic? Thanks

Re: Disassembly of case

This is for a Viewsonic VX900. The bottom bezel with the button unclips.Unplug the connector, and put aside. ( Dont pull on the wires) Then there are two screws that are removed, and the grey frame around the monitor comes off next. Then remove the 4 bottom screws, and the two top tiny screws and the LCD comes away from the back. Remove the shielding, and replace your components. Good Luck !!

I have tried to open the case of ViewSonic VA1930WM LCD monitor. I have removed all visible screws and released all clips around the side. However only the front "frame" releases and is loose...


These units are more of a challenge to get open than most monitors. Here are the steps:

remove all cords - power, VGA/DVI speaker
remove stand - pull off hinge cover and then remove 4 screws
2 screws at bottom corners of case.
Now comes the fun part.
On the bottom edge there are 2 slits on on each side of the monitor about 3-4 inches in from the side. Use a small flat bladed screwdriver inserted in this slot to pop the two halves apart. Once you get a small gap just work your way around the entire monitor until the case halves are released from each other, but don't pull them apart yet. When opening most monitors the front comes off first but on this one the back case comes off first. You will need to again use your flat blade screwdriver inserted between the two case pieces and under the LCD panel and gently apply pressure. At the same time you will need to pull one end of the back case away from the panel, there are two plastic catches on each end that hold the panel inn the back case. One end will release then the other sould come right out so you can remove the back plastic case from the electronics. Now to get to the electronics you will need to remove the two screws on each end of the panel that hold the metal RF shielding in place. Also there is a screw in the center at the bottom of the panel that will need to be removed. Next unplug the 4 backlight power plugs. Slightly lift the shield so you can get to the flat ribbon cable going from the driver board to the panel. It will unplug from the panel by pressing in on the two release tabs, one on each end of the plug. Now you can get to the electronics. I am guessing you are having power issues with the unit. Check here for power supply repair kits if you need to get parts for your unit.

I hope this helps you get the case off, if so please rate my solution.

How to remove the case on LCD monitors

This tip will explain how to open the case on most LCD monitors. Most monitors will eventually have a problem with the power supply and need servicing. The part most people have difficulty with is opening the case to get to the electronics. You will need a phillips screw driver and a small flat blade screwdrivers. You will first need to remove the stand, place a bath towel on a flat table, lay the monitor down and unscrew the screws holding the base and remove. Next you will need to remove any screws that are holding the back plastic case on, they will normally be in the 4 corners and possibly 1 in the bottom center of the back. Now take the small flat blade screwdriver and insert it between the two halves of the case in the center of the bottom. Be sure to not do this by the control panel so you don't break it. Gently pry the two halves apart. Most monitors will have several plastic latches around the perimeter of the case, usually 2 on each side that will need to be released. As you separate the case halves the latches will release and the back will separate from the front. You will need to unplug the control panel cable at this time before you can get to the electronics. Now you just need to use the phillips screwdriver and remove the metal shield from the electronics to get to the power supply. See pictures below.
Now release the catches as seen below:

chrisc257, Yes, you too, will need to watch some video clips @YOUTUBE !!! Search and view 6 to 10minute clips of "LCD monitor disassembly" and "LCD monitor repair" and stuff relating to "bad capacitors in lcd monitors" . Are you doing this as a SCHOOL SCIENCE PROJECT that you will be graded on? First remove the pedestal stand from the back cover.(screws or some locking TABS) Then remove screws from back cover. If you can see them. then un-snap the cover from the front bezel. Watch how they do it on youtube and be careful not to injure yourself or the monitor LCD panel..

How do I open it to look inside?

First, lay the tv/monitor on its screen on something level and soft as not to damage the screen. Remove any visible screws that seem to attach the base to the unit. Some models you have to look under the base for pins orso to push together to slide the base from the stand, only then you could reach the 1 screw holding the monitor to the stand....Once stand removed, remove any screws you see holding the monitor casing together, usually only a few screws since they are mostly held together by plastic "clips"...Once screws are removed, then gently insert a flat(screwdriver orso) inbetween the case?housing, repeat this all the way around the case/housing till completely loose....You will prob have a few wires or maybe a ground wire that you would have to remove before completely being able to seperate both sides(front case, back case)..Sometimes you might have to unscrew and remove the skinny washer/nut around the cable input orso..
Good luck!

To disassemble your monitor follow these steps.
1. Remove the stand, usually 2 to 4 screws
2. Now there will be screws in each corner on the back of the monitor.
3. Take a small flat blade screw driver and seperate the two halves of the case. The front and back are held together by plastic latches spaced several inches apart around all four sides.
4. After the back case is off the boards you will be looking for are under the metal shield, remove the screws that hold it on.
5. Check my web site at , we have pictures of what the bad caps look like if you are not sure.
6. Be sure to replace any capacitors that have raised and blown tops.

I hope this helps, If so please rate my solution.

Remove base of envision lcd monitor G19LWk

The base of the G19LWK can be removed but it takes a little work. You have to remove the black plastic case that sandwich the LCD screen. First remove all the screws on the backside of the monitor. Then, at the seam of the two casement halves, GENTLY pry the front screen frame away from the display. Work carefully all around the edge of the display to separate it a little at a time and the pull it away in one piece. Next you will find that the back casement is held to the display with plastic tabs around the perimeter. Carefully pry the tabs away from the display frame to separate and remove the back casement. Now the base mounting is exposed on the backside and held with 4 screws. Remove the screws and the base will come free. Re-assemble the casement by snapping the back on first followed by re-installing the screws. Then snap the front frame by lining of the plastic tabs and pressing the frame down evenly around the display. You are done!

Acer p221w monitor removing base

Since you have surely looked, it isn't held on with exposed screws.
Check to make sure that the rounded area that allows tilting is not part of the case but appears to be separable.
Most that are removable are held by a tongue and a fairly obvious release tab.

if you can't remove the base, just place the monitor in the carton on good padding and upside down.
Fill and cushion the sides well, mark the carton with 'This side up' and an arrow and hope there are no malicious handlers on the trip.

I've shipped numerous monitors of different sizes and types and have lost none of them to shipping damage.

How to dismount the monitor

What stand do you have? If it is screwed to the back with 4 or 3 screws, they must be removed first. look along the bottom edge and you will see 3 slots where the two outer cases match up. Put a flat screwdriver into the opening and twist, follow all the way around until you can remove the back half. Cut the tape holding the flat wire and remove the front half to remove the printed board under the front cover. You should now be inside the case. Remove the screws to remove the steal cover to find the printed boards under it. Reinstall is the reverse.

Compaq FP 5315 Monitor Disassembly

This is how I did it.

1- Remove the four screws in the back of the monitor. Two are in the bottom corners and two more near the bottom center ( these hold the stand in place).
2- Remove the stand.
3-The case back is held on by the four screws and a number of plastic pressure clips. After removing the screws: using a fairly wide flat bladed screw driver; insert the blade in either of the two slots on the bottom edge of the case and twist with medium force. This begins the seperation of the back from the rest of the monitor. As the crack widens, begin moving the blade of the screw driver along the widening crack (around the case edge) and twisting gently. This releases each pressure clip in turn. Separate the case back from the rest of the monitor.

I did this this way with my monitor. It works.
Good luck.
