The monitor will not stay on only for (3) seconds then goes off, smell of burnt electronics fill the air, further identification revieled that a burnt mylar capacitor connected to High Voltage transformer seems to be the culprit the identification on the capacitor is
i tore apart another LCD monitor and found similar part to be
my assumption is that it is a 22,000 pf
anyways i replaced the capicitor with the similar one and the LCD monitor is working fine so far, is there anything i need to watch out for in the future ?

1. CRT or LCD? 2. Do you have an image of any kind for that 45 sec.? When it drops out after 45 sec, do you have any strange behavior as you look at the screen (colors, blinking, lines, squiggles, noises, smells)? 3. When failing, does the power drop out (ON light goes OFF)? How long do you need to wait until you can turn it ON again? 4. What is the status of your screen saver/power saver? 45 sec seems pretty short but it's still possible. 5. What does the manufacturer's website have to say about this problem? What do other users have to say when you search for your model?
I know these are just more questions but your question is too generic to offer specific comments that might be more useful.
I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.
Certainly, if you jumper the connections to see which ones turn the monitor on or off, then you can go to an electrical supply place and get a micro switch and wire it in in place of the power button, or perhaps find a type that is flat that the power button can press. What you need to determine is if it is a push-on, push -off type switch, which always stays on or off depending on position or if it is a momentary interrupt switch where the button pressed momentarily turns it on and then releases and a second press connects the circuit to turn it off. You can do this by testing with your jumper wire, attach it and if the monitor stays on when you remove it, then goes off when you attach it again, you need the second type switch, if it goes off when removed, you need the always-on always -off first type switch. .
you can try to change the screen resolution with a spare monitor to a different setting, usually higher 1024X768, then unplug the old monitor and then plug in the flat screen. try different resolutions untill it submits. if you cant get it to run on your machine, take it to another computer and see if you can get it to run on that. if it wont run on either then you have a problem with the monitor. pawn shops usually have flatscreens for way cheaper than new..
you have problem wit the lamp just plug in another once you removed the back cover and if the lamp stays on the it is 100%. you do not need original lamp. Any 15" lcd lamp that fits will do the job. HA HA well done
Hi I have similar, I'm an electronics engineer and took mine apart only to find the power supply is very sick to the pint the pcb that converts all the signals probably has been damaged too, ie BIN FODDER.
Not very constructive but at least I know what is wrong - if I can get any constructive info i willl post it....
The LCD screen may be burned out. There's whats called an invertor board and there is an electronic ribbon strip on the LCD itself. If you look very carefully you can probably see a faint image on the screen. The LCD screen will need replacing. Before doing anything with this monitor, try it on another computer first and if you can try another monitor on your computer. Other than that, there really is nothing you can do but replace the monitor.
