Monitor A circuit breaker popped, and when reset the PC started fine, but the monitor didn't. It's a 15 inch flat panel. The power light will blink from orange to green, and there will be a momentary flicker on the screen (it's too quick to tell if there is any content or if it's plain white) each time the light changes from orange to green. It behaves as if it's in sleep mode, but nothing I do will wake the monitor. It does this regardless of which PC it's attached to and other monitors work fine on the PC. We had surge protection on both pc and monitor. Is there a way to reset the monitor? It's a Dell E153PC 15 inch TFT LCD Flat Panel. There are four buttons on the front of the monitor, one is the menu, one has a plus sign, one has a minus sign, and the fourth is the power button. I have discovered that if I hold the minus sign button down, the power light will change to just orange and stay that way unless I disconnect power then it will return to the blinking state. I also cannot shut the monitor off with the power button. I've tried holding buttons down when I connect power, in all combinations, to no avail, I set up a computer to go into sleep mode, connected the monitor, then woke up the computer with no luck, I placed a PC in hibernation, connected the monitor, woke up the PC, and no luck there either. Is there something I'm missing? I've swapped out the cable with one that I know works and that didn't help, I've replaced the power cable (I know, but I'm desperate) and that didn't help either. Any further ideas would be most welcome.

THIS IS LOGIC CARD PROBLEM,U CAN CONTRACT YOUR NEAREST SERVIC CENTER.

You have to remove the stand and use very thin flat balde screw driver to pop the front and the back panel apart starting at the bottom pf the unit. Are you sure that the back light lamps are bad? More likely to be the inverter circuits of bad capacitors in the power supply which is more likely, and if it does have bad caps, it will usually take out the transistors in the inverter circuit with it.

The monitor should be plug and play, and you've already figured out that it's not your computer by plugging into a working monitor.

This is most likely the power inverter board in the monitor - this is common in many monitors. If the power light is blinking on-and-off, or just staying on with no image, that's the problem. There is a slight chance that it could be the light itself, but inverters fail more commonly.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

Depending on when you bought it. There should be at least a one year warranty. If its still under warranty have dell replace it.

some transistors on the board have shorted they supply power to the inverter to run the lamps, they power is not cut off intermittently and the protection circuit has stopped the monitor. the fix is here

goo dluck if you want it fixed for you let me know

The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

• Video cable.
• Video adapter on PC (sometimes integrated on motherboard)
• Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing statebecause of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

I am sorry about this but the correct repair for this issue is replacement of 4 transistors on the main power board inside the monitor I just completed a repair on a dell 17 inch monitor it now works flawlessly. the process can be found on the internet and it is very delicate work. if you can all their service center you used then by all means call them,
And just fyi TYPING IN ALL CAPS IS THE SAME ASSCREAMING AT THE TOP OF YOUR LUNG SOO PLEASE STOP AND USE CORRECT NETTIQUET.
you have a nice day now.

Check power board.

I would suggest that the "Event" that caused the CB to trip has caused ya Monitor to fail.. Probably in the Power Supply, My "Pet" area... lol.. anyway Thats wat I would think. It may even have an internal "Fuse" that has "Blown"?
