SOURCE: monitor light blinking

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.

SOURCE: I have a L194WT LG Flatron monitor. One day it

Same problem started happening two days ago and ever since. I called LG and the product falls under a 3yr product warranty according to them (from my original purchase date of January 20, 2007). They will send packing slips to me so I can send the defective unit back to LG. I was told I am eligible for a replacement monitor - which will be shipped to me within 10 to 14 days (consecutive days, not business) - although I'm not sure what I'm being sent in return. My suspicion is that this monitor issue is a known issue by LG and they are quietly replacing the unit to those who follow through by calling CS.

Tips: Have your original purchase date on hand (in the form of a receipt) just in case they want proof of purchase.

Monitor lcd lg flatron w2252s prende y se apaga a instante


this sounds like you need a new inverter. it sits behind the trim just under the lcd screen. you can get the inverter from most lcd screen specialists or ebay.

Monitor comes on and goes right to a black screen like the power was turned off but the power light is still green.


hi,
You have to check the back light of your lcd monitor. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

The problem is in the inverter board, the most common problem is bad capacitors, inverter transformers, or back light issues. The power supply and inverter share the same board, attempts can be made to repair or replace the board, if a professional gets involved you are further ahead in buying new.

I have a LG Flatron L1718S; the screen display for 2 sec and then turn Black.


If the power light remains on after it goes black, the problem is the inverter board that powers the back light behind the screen, the cause is usually bad capacitors. To fix it, the board must be replaced or attempt made to repair the inverter board.

You could have a faulty inverter board or a faulty CCFL lamp. The inverter supplies high voltage to the CCFL lamp and the CCFL lamp is a mini fluro tube.

Screen flashes only for a split-second (as a second display for an iMac)


The inverter is faulty.If your Monitor is powered by a mains'kettle' type lead,then it MAY be repairable,provided you can find someone to do it.If you have an external power supply,then the chances are you have a separate inverter,and it is doubtful whetther you can find the fault or a replacement circuit board....which is why we have become a throw away nation !!

MONITER LIGHT IS GREEN BUT ONLY SHOWS A NORMAL SCREEN FOR 1/2 SECOND THEN TURNS BLACK


HI. I had the same problem with mine. It would flash the screen on for a split second and then turn black, the whole time the power light remained green. Upon opening up the case, I pulled the combo power supply board/inverter board out for inspection. I noticed one of the capacitors had a bulge on top indicating it was bad. It was the the 680uf 25v capacitor. I desoldered it, and soldered in the new one. After hooking everything back up, bingo!! Monitor now works perfectly. I couldn't find an exact match to the capacitance locally, but I had a 1000uf 35v cap in my utility box. It worked fine as a replacement. You can usually go within 30 percent of tolerance and be alright. Just don't go under on capacitance or voltage. I hope this helps.
