Question about LG L1919S LCD Monitor

1 Answer

The power cable is tested OK and works, but no power into the Monitor, this must be an internal problem or is there some reset that I do not know of, the monitor is 2 years old since purchase. Can this be fixed?

Cprogs, Check your warranty with LG (Lucky Goldstar) and hope they don't say "You bought it, You own it, Toyota!!!" Check to see if they have a swapout program for black screen of death "premature monitor failures." This unit could have a "switch-mode-power-supply" that has detected a FAULT CONDITION with itself or the "cold-cathode-fluorescent-lamp" inverter circuit and is now in partial or full shutdown mode trying to save itself from a catastrophic, nonrecoverable failure. e.g. sparks, smoke, fire!! Yes, it can be fixed. But why don't you visit youtube FIRST and view video clips of "LCD monitor disassembly" and or "LCD monitor repair" to get a handle on exactly what is involved in the repair of your now USLESS HUNK of JUNK lcd monitor. Yes, it could have an "OPEN FUSE" inside on the SMPS board. Read more stuff in my fixya profile for other options you might consider. 12fixlouie

I have an HP the monitor doent turn on but all the light are on how can i fix it.


1. unplug the monitor from the computer and check if you can see the monitor selftest (you will see diff color bars moving around) if you see the monitor self test then your monitor is working fine

2. check the cables. use a diff cable to connect your monitor to the computer. use a known good cable.

3. plug in your monitor to diff computer if it worked then you have to reseat your video card
(NOTE : before removing any internal parts from your computer. your pc must be off and the power cable is removed, after removing the power cable press the power button for about 5 secs to remove any electro static discharge)

4. after reseating the video card and still doesnt work remove the video card from the computer. use the onboard video card if you have one.

if it does work then the video card needs to be replaced.

you can also try to reset the memory by removing them and reinstalling them inside the computer

hope this help

Dell E153FP monitor won't display any video from system (Dell GX260). My e173FP monitor works fine. E153FP powers up, runs Self Test Feature Test fine, menus all seem OK. Tried Factory Reset... still no...


You probably have tried this, but make sure monitor is set to correct display... i.e., Analog or Digital

Also, try starting in safe mode and verify Monitor is able to handle the display settings resolution

I have the same problem!


Hi Robert,
The monitor is on protect mode because an internal fault had been detected.
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 occur 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 state because 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.
