Re: Monitor not staying on

I had this problem with two E153FP monitors. I cracked open the case, yes cracked, there are no screws just two slots at the bottom where you can pry it open with a screw driver. Pry around the edge and it opens up. Then you can disassemble down to the power supply. Find a large 1000uF 16V electrolytic capacitor and replace it. I did not have a 1000uF 16V cap, so I used a 940uF 50V cap. It works and I think the higher voltage rating will make it more reliable.

Re: Monitor not staying on

Try this...
Leave the monitor off.
Turn the PC on and watch the hard drive light flicker.
After a minute or two it should stop or at least slow right down.
Turn the monitor on and see if you can see the desktop. (in some cases you may only see the DELL screen before it cuts out again. If so, then just leave it on and use a good torch shining down from the top at an angle to the screen and see if you can see your desktop that will be very feint)

If so, it will still cut out very quickly, but it is a fault in the inverter circuit on the power board in the monitor.
A trip to your local TV technician will have it back up and running quickly and should not cost that much to have repaired.

When powered on led comes on and then off. monitor is now black and wont come on.

Hi. Try to run the diagnostics by turning the computer on, press F12 on Dell logo, select boot to utility partition and press enter.

If it doesn't have utility partition, then try to remove the video card and put it back in... then turn the computer back on.

If it still doesn't stay on, then you might have to replace your motherboard or buy a new desktop CPU.

Nothing is wrong with your monitor though.

Dell monitor will come on but will not stay on. stays on 5sec

5 seconds? Hmm, too long for inverter driver turning into protection caused by bad lamps. Also too long for PWM controller in the switching power supply.
Rather looks like overheating of the FETs in the inverter, they are driving HV-transformers. Open the monitor, remove metal lid and observe inverter board. If PCB under and around these FETs is darkened, replace them.
These Dells hard to open. Take the foot off and unscrew plastic cover. Then using flat screwdriver with wide blade separate plastic halves of the case, starting from bottom edge and moving to opposite. It might be sweaty.

You have capacitors on the monitors power supply that have changed value. Soon they will keep the monitor from turning on at all. Send it to a company like mine or take it to a local repair person.

Dell monitor 15 inch the green light stays on but no picture

It's the backlight supply tripping out from backlight failure, but the thing still stays on. I got it to act right by switching to factory presets with some fast menu action once, but the general solution is going to involve tricking the backlight into staying on; you can look at the thing in bright ambient light to see that the display is still working, but of course without a backlight it's pretty much useless.

Since $100 buys a better and more efficient monitor, just replace it; otherwise of course you can either replace the backlight (or go for one of the projector mods) or convince its drive circuit to put up with it a bit longer. I spotted a bad capacitor but swapping that out hasn't gone well yet....
