Acer Ferrari F-22 LCD monitor, won't stay on, that is when it comes on. It was on yesterday for a little while but then went off, It is not a computer issue, I have ruled that out. I have also opened the monitor to check for visual damage to any capacitors, didn't see any. Does anyone have any ideas or suggestions? thanks

Power supply or converter within the monitor would be my first guess.....

Power supply/inverter is the first candidate, with bad electrolytic capacitors (not always visibly faulty) or fractured solder joint(s) likely causes. Unfortunately a bad backlight tube or other component fault is also possible, and it's not simple for the cause to be identified outside of an electronics workshop.

Are is the powersupply/inverter the same board? There are 2 boards in the monitor. One large and one smaller.

Hi
The power board should be the one the AC cord plugs into as well as having the largest capacitor(s) on it.

3 year warranty, how old is it?

You're probably not going to find a "kit" as such, because no-one knows which components are faulty.

If you're considering capacitors, badcaps has some kits for common problem motherboards, but not specifically for monitors, as there is just so many. They do sell a range of individual capacitors. If you have soldering ability ( and to be safe, understand electrical precautions), you could try replacing the electrolytic capacitors on the power/inverter board just to see if that cures it.

Many electronics wholesalers, repairers or hobbyist stores would also be able to supply decent quality 105C rated capacitors.

Hello,

Before buyng capacitores, I would like to suggest to ressolder all componentes in the high voltage section using flux soldering liquid: coils, filter capacitors, bridge rectifier, terminals of the chopper transformer, the MOSFET transistor and the big resevoir capacitor (something lilike 100 ou 220 microfarads and 400V of working voltage. This component must be discharged, shorting its terminais with a screwdriver. And then test your monitor. If this not work, look for lW or 2W resistors having signs of overheating; after this resistor can be a faulty component which get interrupted when heats up.
Next you can replace the electrolitic capacitor on the inverter board (if any). It is hard to find out a leaky or dried capacitor and replacing them seems the best way.
I hope have helped.
