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

There is an electrical problem with either the power cord connected to the monitor or the outlet that it is plugged into.

If its a brand new monitor, return it to the place of purchase and exchange it.

If its a used monitor then I would suspect that someone has given you the wrong power cord for the unit. Sometimes people check to see which cord "fits" the unit and think that its appropriate because they can connect it.

That is not correct when it comes to monitors. Just because a power cord fits by connecting to the monitor does not always mean its appropriate to run it correctly.

Check the voltage requirements on back of the monitor and compare them to the power cord your using with it. If they are appropriate and your still experiencing this problem then the power cord might be bad.

Test this possibility by disconnecting the monitor from the computer and turn it on. Do you see a screen that says "no video" or "no connection"? Does the screen blink the same way as when connected to the pc? If it does, then its the power cord or supply source its connected to. Plug it into another socket and and see if you get the same thing and that tells you its the cord.

If the display is good when not connected to your pc, then use a process of elimination to figure out if its the monitor cords connector that is broken or frayed or if its the video card connection that is either loose and needs to be re seated in your case or the connection itself is unsturdy and needs the bolts tightened to give a solid connection.

How do you do that?

Check the pins on the end of the cable that connects the monitor to your pc. Are any broken, missing or bent?. Check the other end that connects to the monitor and verify the same thing.

Then try and jiggle the video card by grabbing the area that you connect the monitor cable to on the back of your pc's case and see if it is loose. If it is, get a screwdriver and tighten the screws until its tight.

Try plugging it in again and see if this solves your problems. If it doesn't then clarify your findings and I will help you solve this issue another way.

have it check, or might be better have it replace, any connection regarding electric current supply should be tightly connected, if it is loose, it might cause some serious problem like short circuit or even worse is FIRE, just bring it to the technician and have it change, also with your power switch

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.

Generally, if the power light (LED) doesn't come on and there is no screen display with or without input signal, it's dead. Probably a failed power supply.

hi im josh in cebu phils.may i help you? Friend try to use these solutions i got this in my book.
Dealing with System Startup Problems There's nothing scarier than turning on your computer and finding it doesn't start. What you do next depends on exactly what it is your computer is or is not doing. Let's work through some specific startup problems, and how to proceed in each instance.
Problem: Your Computer Doesn't Start—You Hear No Noises and See No Lights First things first—don't panic!
Now, very calmly, look at the back of your system unit. Is the power cable plugged in to the right connector? Now follow the power cord to the other end. Is it firmly connected to a power outlet? Now check the wall switch. Is it turned on? Now walk to your fuse or circuit-breaker box. Is the fuse good or the circuit breaker set? Now go back to your computer. If it still isn't working, unplug the computer from the power outlet and plug in something that you know works—a lamp or a radio, perhaps. If the appliance doesn't work, you have a bad power outlet. If the appliance does work, you really do have computer problems.
If you're positive that your computer is getting power and that you're turning it on correctly, you probably have a hardware problem. The most likely suspect is the power supply in the system unit. To determine the culprit and fix the problem, however, you'll need to call in professional help at this point. Take your system to a certified repair center and let its technicians get to work.
Problem: Your Computer Doesn't Start, but It Makes the Normal Startup Noises If your system is making noise, at least you know that it's getting power. Because you can rule out a bad power cord, the most common things to look for are poorly connected cables or a nonfunctioning monitor.
Begin by checking your monitor. Is it turned on? Is it plugged into a power outlet? Is the power outlet turned on? Is the monitor connected to the correct port on your system unit? Is the connection solid? Is the connection solid in the back of the monitor? Are the brightness and contrast controls turned up so that you can actually see a picture? If you have a newer monitor, try disconnecting the monitor from the computer (with the monitor turned on); if the monitor is working correctly, you should get a No Signal or Lost Signal message on the screen.
If everything is connected and adjusted properly, you might have a monitor that needs repair. Is the monitor's power light on? If not, your monitor might have power supply problems that need attention from a professional. If your monitor's little green light is on but nothing shows onscreen, the video card in your system unit might be loose or set up incorrectly. Try swapping monitors with another system; if the new monitor works on your system, your monitor is the problem. If you determine that your monitor is working fine, you should check your video card to make sure it's installed, seated, and connected properly. If that doesn't fix your problem, try plugging your video card into a different slot.
It's also possible that your keyboard isn't plugged in properly, or that you have some other internal problem that causes your system to halt during start-up. Check all your connections before you try rebooting. good luck hope i helped you.

hyundai will not repair this however a electronic service center aka tv repair may. I can do it as most likely is it several capacitors that have blown. Hyundai is also a little picky to open they are assembled very well actually compared to other monitors (they are difficult to open up) let me know what you would liek to do.

The two vx900 s I have here have more of a rectangular plug for the power. Inside it is three large prongs and on the backside should be 3 wires. Two of which go to a smaller plug that connects to the power board.
The power cord is the same as found in many desktop computers.
If this is what you are referring to. Then the plug should be connected inside and it snaps into place onto the meatl part inside the monitor.
You may have to disassemble the unit to get it back together.
Sorry for delay in reply, I never was notified that you had replied.
