Generally inside there is a fuse on the power board. This fuse is soldered in on the board. Before taking this apart and testing the fuse or replacing power board or inverter, test the power supply to make sure it is producing the correct voltage and amperage.

If the fields of the "Brick" are breaking down this could also prevent the unit from operating.

I have old 14L8 IBM monitor type 6321-003.There is no connection on power cable when I switch on it. Is it possible to fuse is dead? Or power suply is gone?Thanks.


You can test the power cord out with a volt meter to see if this is the problem, or you can replace the fuse or the power unit inside the monitor my best answer is by the time you have paid for all of that unless you are just curious about how to do this. I would since it is an old monitor go to Goodwill or some garage sales and get another one. That would be what I would do. Why hassle it and the expense. I could see it for a good LCD or something of that nature investing in this. I think you may have already decided to do that. John

Tip

Monitor LCD Screen Replacement With A Laptop Screen


This tip is for the typical PC tech with a shop full of dead laptops and monitors, looking to make an extra Monitor for bench testing malfunctioning PC's. Maybe you're a tinkerer and just have some spare parts laying around, and want to make something cool and easy. Either way, this tip is a fun way to make old dead parts work for you, rather than sitting in a corner gathering dust.

Replacing a Laptop screen is pretty easy if you take it slow.
LCD Monitor screens are actually easy to replace too, if you are careful not to crack anything getting one out and in again.

This tip doesn't address any of the typical replacement methods.
What this does is show you how to use a laptop screen in a standard Desktop LCD monitor.

Having already disassembled your Desktop monitor, and determining that one or both of your backlights is dead, you will most likely begin searching for sources of a new one. Before you do that, try testing both backlights in the dead monitor screen first by hooking them, one at a time to an inverter in a working laptop to verify that both are dead.

Most of the time, you will discover that only one light is dead, and this is where the fun begins.

At this point, you have a few choices to make.

1. Extract a working backlight from a cracked LCD, we all have a few of those lying around somewhere in just about any PC tech area.
2. With the extracted backlight in hand and the old LCD screen still attached to the monitors electronics, remove either of the sets of wires going to one of your backlights, leaving one still attached.
3. Now you can attach the light you extracted to the empty socket your original screens light attached to, while leaving the other one still attached.
4, Now, turn on the monitor and wait for the extracted backlight to come on, if it doesn't switch it with the other light socket plugged to your screen, and plug the opposite light wire back in.

This will do 2 things for you. First, it will be a quick test of your inverter, and second it will verify that you do or don't have at least one working backlight still functioning in your monitor.

Remember that with most LCD monitors, just one backlight can provide enough illumination for your screen to show a very crisp picture.
The problem appears though, when we decide that our existing LCD is dead because we dont see it light up.

The solution for this is to simply disconnect the dead light wire from the existing inverter plug leading to the LCD screen, then replacing that with a working light from the cracked screen without disassembling the LCD screen itself. If you did everything right, your old dead screen will be working as it should. Be sure you swap the backlight connecting wires so that your Bright/Dim controls work as they did before.

You see, most dual light inverters work the same as a standard twin tube household flourescent light. When one goes out, they both eventually stop working. So, adding that second light completes the circuit, then swapping light socket connectors turns your backup light tube into the primary light, instead of the secondary.

Now, if THAT trick didn't work, you can move on to the Laptop LCD trick, which is pretty much what you did before, except that the Laptop LCD usually only has 1 light tube. So for this to work, you can complete the lighting circuit by simply adding your spare backlight tube to the second open backlight connector, then installing the LCD to your monitor.

Many of these Laptop LCD screens are the same height and width as comparable Desktop screens, but they are also thinner, and will have to be glued or taped to the frame from the inside. Everything else connects exactly as the original screen, but may need to have wire added to the Laptop backlight wire so it reaches the power source.

I figured this tip was worth posting, since I just did this trick with a 15" polaroid HDTV/HDMI/HiDef Television/Monitor combo.
The model I have died a few months after it was bought new from Walmart, and the customer just didn't feel like paying $129 for a new screen.
Being the packrat I am, I just couldn't bear throwing it away, figuring that some day I would find a matching screen. As you can see, I got tired of waiting. The pictures of my project are below.

dc79966.jpg2e21d78.jpg

That bright line of light isn't the flash from my Camera, it's the flourescent light tube from a broken LCD screen placed on top of the steel housing.
The incidental effect of that light is that my back wall is a nice nitelite, and hooking up new components is a lot easier. Yes I could have blacked it out, but I think I like the added light behind the TV.

I hope this Tip comes in handy for you.

My Dell Optiplex 620 started rebooting itself every time Windows started up and then it just went dead. I push the 'ON' button on the front of the computer and nothing happens. I have no lights, no fan,...


I would suspect that the power supply has gone bad and has to be replaced. A simple task, really. var fctb_tool=null; function FCTB_Init_b10486e133b24d6ca38e4d39d69b43a1(t) { fctb_tool=t; start(fctb_tool); } var fctb_tool=null; function FCTB_Init_ee2e8b71ff554752b93d52dd01ec84ba(t) { fctb_tool=t; start(fctb_tool); }

The fuse has gone inside the casio 160cr-b how do i change it


Most of the simple models have no fuse. The two most common causes are jammed printers (this can cause the machine to seem dead) so try turning the printer gears and make sure they are free to turn. The other common faurt is an open circuit power transformer. ----------------------------------------------------------------------------------------------

We have relisys TL735S and altho connected to pc cant see how to reduce print so we can see everything on screen and the tool bar at bottom of monitor.


If you have a button if the front of the monitor that automatic sets the best resolution, press it, if not, rightclick anywhere on your monitor, select preferences and change the settings there
The recomended resolution for your monitor is 1280 x 1024, thats also the highest resolution your monitor suports. Start whit the resolution 1024 x 768 and set the mgz to 70. I think that should do it for you.

Good luck
