Case removal My B90D Monitor has a loose connection at the power plug on the back on the unit. I need to find out how to seperate the case to repair the connection.

Step 1:
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Causes a Computer Monitor to Go Blank b> While a blank screen may be caused by a general power outage, more often it's a problem with the screen itself. It could be a loose video or power cable going to the monitor. If that's the case, you can get the screen working again and be back in business in a few minutes. b> Power Problems All the power might be off due to a bad outlet, switch, fuse, or circuit breaker. If you hear no sound coming from the computer and its power light is off, check the power connection and breaker or fuse. Video Cable Many times the cause of monitor blackouts is a loose video cable connection. This might happen if you move the monitor or the cable. The video cable runs from the back of the computer to the monitor. It has a multi-pin connector on each end and both of them screw down securely. If the screws aren't tight, either connector could become loose. If that happens, the video signal could stop suddenly and make the picture go blank. Check both ends of the connector to make sure they're firmly seated and the screws are tight. The cable itself might be bad.This is unlikely, but possible. b> Display Power The monitor must have power. If the power light isn't lit on the monitor, it may have been turned off or become unplugged. Press the power button to make sure it wasn't accidentally turned off. Make sure the monitor is plugged in. If it's connected to a power strip, check that the power strip is on. If that checks out, unplug the monitor and try a different outlet. Power strip sockets can sometimes fail. Flat-screen monitors may have a power-brick-style adapter. It, too, has connectors. Follow the power cable from the monitor's power plug back to the monitor. About halfway up you'll find a thick rectangular plastic brick. The power goes into a modular-style equipment socket. This can become loose. Follow the wire the rest of the way to the monitor. It connects to the back of the screen with a small round plug. Check that it's firmly plugged in. If everything's plugged in right and the power light on the monitor's still off, the power brick might be bad. b> Video Card Some computers have a separate video card inside. It may come loose and cause a blank screen. If this is the case, open the computer and inspect the video card. Sometimes removing and reseating the card will fix the problem. If it has to be replaced, most video cards are not expensive.

Good work

A very dark blue screen on a laptop that otherwise appears to be "on" is a sign that the backlight on the screen portion of the computer may be burned out. You can test this by shining a flashlight on the screen. If you can see your desktop icons, the backlight is burnt out. Replacing a bad backlight is not a do-it-yourself task unless you are comfortable doing delicate electronic repairs and have the design schematics for your model in hand. Your safest course of action will always be to take the laptop to a professional repair depot. There is one alternative repair option available if you're not comfortable doing surgery and a trip to the repair shop is not in your budget. Replace the entire screen module, case and all.

Doing Surgery Yourself

1.Remove the battery from the laptop. With the laptop model schematics in front of you, use the small Phillips screwdriver to separate the monitor from the laptop base. The schematics will indicate how to uncover the monitor hinges and free the monitor. Handle the screen gently because it will still be tethered to the base by a group of wires.
2.Remove the plastic case covering the "power bar" on the upper part of the laptop keyboard base. Refer to the schematics to find the way to release this cover and lift it off the keyboard. You'll see a group of fine wires leading back to the monitor. Unplug this cable so the monitor is now free from the base.
3.Follow the schematics to remove the casing covering the monitor screen. Be forewarned that the design of a laptop monitor "under the hood" is complex and delicate. Don't force anything. Don't experiment. Take frequent photographs of each successful disassembly stage so you can have some hope of getting it all back together again correctly.
4.Find the slim fluorescent backlight instrument behind the glass layers of the screen. Unplug it from the tiny cable receptacles and remove it. Insert the fresh backlight fixture and reconnect it to the cable plug.
5.Restore the screen assembly and the casing using the schematics and your reference photographs. Plug the screen back into the laptop base at the power bar. Don't reattach the screen hinges to the base until after you have tested it by booting the laptop. If the test is successful, turn the laptop off and connect the screen to the base unit at the hinges.

Alternative Repair

1.Purchase an entire screen-and-case assembly for your laptop make and model. Many intact assemblies are available online for reasonable prices. You will usually pay slightly less for an entire screen-and-case unit than you would for a professional repair on just the backlight alone so this could be an economical alternative for you. You can save even more money by purchasing as "Used but Good" unit, rather than a new unit.
2.Remove your old screen following the previous section's Step 1 through Step 3.
3.Plug the new screen-and-case unit into the laptop base. Follow the schematics and your photographs and thread the monitor wires through the hinge passes. Restore the power bar cover.
4.Test your replacement repair by booting the laptop. If the screen looks normal, shut off the laptop and reattach the new screen to the base at the hinges. Restore the hinge covers.

I hope you find it very helpful. Thanks.

Hello,

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.

There is no exact instruction, but first thing you have to do is to remove the stand, then starting at the bottom edge of the case using thin flat blade screw driver to pry open the case up and then work your way around the case, you can also look at YOUTUBE, just search for 'how to repair LCD monitor', 'How to open LCD monitor'
Bad caps (leaking/bulging top) are common failures.

Shut down computer and monitor. Unplug the monitor from the computer. Plug it in again making sure it is connected firmly and that the connection in the back of the computer (video card) is not loose or shaking.

If the symptoms persist and the card appears loose (can happen on older computers) you might need to open the computer case, unscrew and remove the video card and then reinsert it making sure it is firm and attched.

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!

Hello there:
This is usually not a good sign
I will give you a couple of things to try out first ok
(1) you may want to try the monitor on a seperate computer to see if it will work if not than the monitor needs to be repaired.
but if the monitor will work on a seperate computer than this just means that your video card on your computer is either loose or it is not working to test this try these steps
you can try to remove the power cord and open the case and remove the power supply cord that goes to the motherboard than press the power button of the computer for 15 seconds and than if you have a reset button press this button for 15 seconds than plug the power supply cord back into the motherboard and try to reboot the machine and see if this will work if not try this
(2) with the computer unplugged remove the video card and clean the gold edge with rubbinbg alcohol and let dry than reinstall than reboot the machine if still nothing than you will have to get a new video card.
*** NOTE*** if your video card is built to the mother board this is a common thing cause they dont last forever so just get a new video card and install and connect the monitor to that one and not the old one ok?
so please try these solutions and you should be all right
best regards michael.

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.
