Hello,
Very common problem with these LCD monitors. You have a blown power supply for the backlight circuit. If you are comfortable with elecronics repair/soldering I can walk you thru opening the unit and repairing it. If you don't want to do it yourself we have a repair option available for $35.00 plus return shipping.

SOURCE: no power but ON button flashing

Quickest fix for this is probably to temporarily unplug the monitor power cord.

For your other outages, I assume the monitor is connected to a computer, make sure the operating system power-save features have not disabled the video output signal from the computer ... if so, monitor should re-activate when you use the mouse or hit a key on the keyboard.

If your computer has two video outputs, make sure the primary display hasn't been shifted to the other one ... try it by moving the LCD data cable to the other video connector on the computer.

SOURCE: Dell flat pannel monitor fail to power up after power outage

rtutt, First, before you start to tear apart the monitor any further, take pic's (close-ups) of screws, cables and their positions BEFORE detaching them from their board mounted jacks. Second, the fuse will be a small pigtail type soldered to the power supply board. It's the board that will have the connector on it that the line cord plugs into from outside the plastic cover. This is Pretty neat for you because if you forget where something goes, you can always open up another monitor. Well if you get the steel shield cover removed (BE VERY CAREFUL NOT TO RIP OFF ANY CABLES OR MULTI CONDUCTOR RIBBON FLEX CABLES) the cables can then be popped off. you can probably catch a video of monitor tear-down on YOUTUBE.com by doin a search on LCD repair. Yes I have seen some that are 8 to 12min long on the tube. Also you will be visually checking all large electrolytic capacitors for SWOLLEN tops of their aluminum can. You will need a large magnifying glass to inspect the solder side of the board for circular hairline fractures around the leads of heavy and larger "through-hole components, that have been thermally/mechanically STRESSED over the years. they will need to be resoldered. Well any way, keep me posted of your progress. Im louie12fix or lmistyrel@ aol.com PS: I have dell and will take pic's of board!!

Hello,

Depending on what caused the power outage, you may need to replace the power supply in the server. When outage happen and the power is restore. a power surge can destroy power supplies, especially if not connected to an UPS unit.

My lcd monitor is not working after power failure (syncmaster 170t) .


The monitor was probably fried during the power outage due to a spike just before the power went out.
On the power brick check to see if there is an LED light and see if that is lit when its plugged in. If its not lit up then you may want to try a new power brick, if it is lit up then your monitor is a dead.

HP f1703. After a power outage, when computer is


Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

I had a similar problem with a Dell monitor after a power outage. I pulled the monitor apart and found a connector not completely seated. I think that something internal has happened to your monitor. It could be an internal fuse or something. If you don'r feel comfortable taking it apart, find a reputable service center.

Envision Monitor doesn't turn on.


monitor has sustained damage from the power fluctuation's from the outage I would report it to your power company they are obligated to replace any damaged equipment that may be damaged because of their failure to provide non outage service and then go take the monitor to a repair center they can determine if the boards internally were hit with a power spike and damaged, meanwhile while you send the report to the power company you can either buy a new one and then submit the price for refund from the power company

Transformer


Several things have happened. 1st have you tried plugging the monitor in the wall and not in the surge protector. 2nd does your power button or LED light uo when you power it on? You have stated the transformer is bad due to lighting strike. Have you replaced the transformer? Your monitor should be coverd under the surge protector warranty. Please answer questions and we will go from there.
