I have a dell e173fp monitor taht is have problems. When I turn the monitor on it will stay on for a few seconds and then turn off again. Do you have any suggestions as to why this is happening?
Use the dell monitor on another computer, if its having the same issues on another computer then you know the monitor is bad. If its not having the same issues on another computer then you know its a problem with the original computer.
With the monitor turning on and off, if the problem is the monitor for sure then it could either be the lcd screen is starting to go bad or puffy capacitors on either the main board or the power board.
Best way to find out if you can do it. Take the back off of the monitor you will then see a metal shielding cover, take the screws out of that and it will expose the power board which is where you normally would connect the power cord to and the main board that controls the voltages and how info is displayed onto the screen.
A good capacitor has a nice flat silver top on it. A bad capacitor has a silver top that looks puffy or pregnant. It will look like its bulging.
If you find any bad ones, you would need to take a soldering iron and get the bad ones out and make sure you replace them with new ones that have the same UF rating and the same or more in voltage, you can get the numbers off of the capacitor.
The striped side of the capacitor needs to face the marked side on the board.
Again keep in mind if you don't find any bad capacitors on either board then that means the screen is going bad and it would be more cost efficient to replace the monitor then to repair it at that point.
