Yes, but you are dealing with potentially high voltages inside the case. The crackling and sparking are an open short that is being arced but the voltage.
This is one of those things that can be dangerous, so make sure everything is disconnected and that you leave the monitor unplugged for at least an hour so that all of the capacitors can "leak" discharge themselves.

How To Repair LCD Monitor

The most common problems on Samsung LCD monitor/TV:
  • The power can not turn on, the red light flashing
  • the monitor on for a while and then turn off, then the red light flashing.
This is due to the weakening of the capacitor in the power supply module.
let's go hunting for bad capacitor.

I will explain how to:

  • Open the case of the LCD
basically in all LCD monitors have two circuit boards (power supply board and system board)
  • After you open you will see the two boards are
  • You see a board that has a socket for the power source. wrote that the board we're looking for (power supply board)
  • Remove all cables connected to the board and take out the board. (get noted before you unplug it)
  • Now you see it components on board, we looking for capacitor.(see picture below)
  • Looking for damaged capacitors, physically you will see a capacitor on the top like a bloated (see picture below)
  • Replace the damaged capacitor with the same value that you can see on the surface of the capacitor. (In this step you need any soldering tool)
My advice: replace capacitors with higher voltage, like 10V replace with 16V or 25V will be fine.

Have a Nice Repair :)

Acer Monitor V193W has no signal

There are 2 basic reasons for the "No Signal" message.
  1. Loose video card inside the machine- if you're machine didn't come with on board video or if you are using an independent video card instead of on board video, the card can unseat at times, either due to movement of the machine or pulling on the video cord
  2. Loose connection between the video cord and/or monitor and/or machine. Unless the plugs on both ends are secure (including tightening both screws to prevent loss of connection), the cord can dislodge just enough to interrupt your connection, causing a "No Signal".
If neither of these is the case, try hooking up a different monitor (if equipped, you can use an HDMI cable to your TV) to see if the "No Signal" message persists.If using a different monitor works, the issue is your Acer Monitor.

Everything turns on but the monitor. The monitor still has a black screen and the light doesn't come on either. I have tried unplugging it and plugging it back in and also restarting the whole thing,...

The monitor has a power supply problem often caused by bad capacitors that in some cases bulge at the top indicating they are open. If you are handy with a soldering iron then you can attempt a repair. The most common capacitor failure is 1000uf depending on the make and model, the value may be higher or lower. To locate the power supply board follow the power cord that is plugged into the monitor.

My system is not coming up

Might be a broken PSU (Power Supply Unit) You can be doubly sure that the PSU is ok by checking inside the case for LED lights on the motherboard, or by getting a cheap PSU tester from ebay or Maplins.

Seems silly but use the PC power cord in the monitor to make sure the cord works.

Finally if the PSU does work and there isnt a problem with the cord then you have a motherboard issue, it could be a MOSFET IC that needs replacing, either way its a delicate and specialist fix that will need to be undertaken by a service center. If you do go down this route make sure you use a 'no-fix no-fee' service.

My pc not powering up

Is there any light on inside the CPU case? You need to trace the fault from the electric socket. Use a working device (like a hair dryer) and check if the socket works properly.

Next step is to check the power supply cord. Use a multimeter to check continuity or use another cord if available. Next comes the power supply unit. You cannot test it at home as it requires dismantling the CPU which is not a good idea as it may void the warranty. It would be better if you take it to a PC hardware shop as they have spare power supplies and will check it in a few minutes.

My screen has shrunk, there is a black frame around it that i cant get rid of. Iv tried changing the resolution and re-starting my computer nothong has helped

Use the OSD (On Screen Display) controls on your monitor to change the "vertical-size' and "horizontal-size" of your picture.

Then, try a different monitor, to see if your monitor is the problem, or if your video-card is the problem.

I moved my home office desk a few days ago. I properly powered down my computer and unplugged everything. When I reconnected everything, the computer won't power up.

1 - Make sure you have power to the outlet you plugged the computer into. 2 - Make sure all of the cables plugged into the back of the computer are firmly seated / attached.
3 - Check that the switch on the back of the computer (usually quite near the power cord) is turned on.

Monitor wont read the harddrive

First (and I am sure you have already checked this), I would make sure all cables are connected and all power cords are connected. If the monitor comes on but there is no image I would try to use the buttons on the front of the monitor to adjust the brightness and contrast and see if this fixes the problem. If neither of these solutions work, then try a different monitor. If you try a different monitor and still it does not work, then something may be wrong with your video card inside your computer and either the video card will need to be replaced. Or you may need to buy a video card if the monitor plugs directly into the motherboard (big circuit board inside the computer). Hope this helps.

is this an lcd flat panel monitor or a crt? if it is a flat panel then you may be dealing with blown capacitors on the vga board inside. they can be replaced therby repairing the monitor. if it is a crt then just recycle it and buy a newer lcd monitor to replace this old one.
