How do you fix a computer monitor burnout?

Answer 1

If a moniter isn't working try checking the area that the power cord plugs into your moniter. Sometimes when you have your moniter cord rested against a wall it can damage the inside wires. If it still doesn't turn on, the tube is probably out and you need to buy a new moniter.

NEVER TRY TO TAKE APART ANY MONITER. it is deadly.... trust me....-PnkFlydhippie AnswerIf a moniter isn't working try checking the area that the power cord plugs into your moniter.

I'm going to assume you are asking about a CRT (picture tube) monitor. Internally, CRT monitors are very different than LCD monitors. There are so many things that can possibly go wrong with a computer monitor (either LCD or CRT). This question is a very difficult one to answer. The internal power supply could be blown, a fuse could be blown, the Horizontal Output Transistor could be blown in a CRT monitor, etc. Also, in an old CRT monitor, the 120 Volts AC coming from your electrical outlet are converted inside the monitor to 10,000 volts-20,000 volts (at a low current) to drive the electron gun. Personally, I believe you risk being electrocuted if you attempt to repair a monitor (either CRT or LCD) and the risk is not worth the savings. I'd say, either buy a new monitor or have a qualified electronics technician repair it. But I would NOT recommend trying to repair it yourself.

Answer 3

You don't mention the issue with your screen. Is it cracked? Does it have no power? Is the image blurry? Is it a CRT or LCD?

There are several things that can go wrong with a monitor. There are VERY high voltages in a CRT, up to 25,000 volts.

I would recommend that if it is an image problem or a power problem that you take it to a repair shop, or just buy another.

First be sure that the problem is the monitor and not the computer. Connect a monitor that you know works to test this.

Here I am talking about CRT monitors -- the kind that look like old TV sets, NOT flat screen monitors. It is a little known fact that monitors have a built-in fuse. To get at it you have to open the case. WARNING: even when the monitor is unplugged it can give you a dangerous electric shock! The most dangerous part is the back end of the picture tube. BE SAFE: unplug the monitor and let it sit for a couple of days before opening the case! Put the monitor face down on a padded surface like a couch, or use a folded blanket on your workbench. Just behind the plastic that surrounds the screen you will find a number of screws, usually four, one in each corner. Undo the screws and then very gently lift the back of the case straight off. Now you have to find the fuse. The most commonly used fuse is a small glass tube with metal ends. They are about the diameter of a drinking straw and about 1 inch long. It will be held by clips at each end. Locations vary, but they are most commonly at the back of the monitor and lower than the picture tube. There are other kinds of fuses, and some are even soldered in, but you need help to find them. Carefully remove the fuse and take it to an electronics store to buy an exact replacement. The information you need is stamped onto one of the metal ends. Replace the fuse securely, re-attach the back of the case, and you are ready to go

Answer 5

It would be cheaper to replace. It is more expensive if you buy it from the laptop manufacture. Try to find the companies that sell LCD screens on the internet - normally it is exact the same screen but you will get it fast and with less money.

Answer 6

I have a insignia NS-24EM51A14 monitor and when I working I accidentally changed the input. Now whenever I start it up "No signal " comes up and the only button I can press is "power" no "menu". Please help. Found it. Press OK when in sleep mode

Answer 7

It is most likely not the monitors fault but the resulotion your computer wants it to run

By replacing it with a ASUS mother board!
