Question about LG Computers & Internet

I have an LG Flatron L17NT-A monitor. It doesn't power up even though it's plugged in. Any idea where to get a new power supply unit for it, or is it better to just buy a new one monitor? Thanks, -Matt

The most likely cause is bad capacitors or a fuse in the power supply board.
Dissassemble it, its not very hard, and get the board out so you can see the round barrel shaped capacitors, if you see tops that are rounded rather than flat, then they are bad.
These can be replaced rather easily, there is a complete set of capacitors on eBay for about $12, individual capacitors are much cheaper from mouser.com, but you have to pay shipping, so the ebay item is probably the best bet.

You might need to change the monitor's power supply. I have seen similar problems with other LG models. Usually it is easier to replace the power supply than trying to troubleshoot it.

Replacing the power supply usually involves a few screws and a few cable connections. Troubleshooting the power supply board itself usually involves soldering replacements for blown capacitors.

Hello,

Two things, First you need to replace all of the capacitors on the power supply board at the same time even if they do not show signs of failure because they have been under stress. Secondly, you need to use the correct ratings on the capacitors not just the mfd and voltage. Parts from Radio Shack and such will not work right and can cause additional damage to the power supply board. Here is a link to an article about getting the correct capacitors for LCD monitor repairs.

Hello my flatron l206wtq-bf doesnt work the light of power flash blue and the monitor doesnt open do you have a solution for me thanks


Hello,

Your unit has a power supply that has failed. When the power board starts failing you may get a wavy display, it may be slow to show a picture or you may just get the flashing power button light that you have. The problems are caused by parts called capacitors that have bulged and failed. Here is a link to a repair guide for the LG L226 that uses the same power supply board as your unit.

The dis-assembly information is almost the same to.

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

My LG Flatron 1710S computer screen doesn't have any power. Sometimes the power light will start flashing but most of the time it stays blank.


This is a common issue, the power supplies in LCD monitors fail prematurely. (if your monitor has an internal power supply) , Double check all your power connections, but it sounds like the internal supply is toast, (its a simple capacitor replacement to fix, but cost to do this job seems to always outweigh a new monitor purchase) sorry to be the bearer of bad news.If you find my answer helpful albeit poor news, please use the thumbs up feedback.

LG Flatron L194WT Monitor no power


It can be as simple $5 worth of caps in the power supply.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

How do I turn the monitor in


It sounds more likely to have power supply failure if you hit the power button and it does not turn on.

Hi there, my name is Alex and I am here to help solve your problem.

When adding a new monitor to your computer, it is not necessary to install the monitors drivers as it should detect 'Plug and Play monitor' and will install the monitors drivers automatically. Are you getting any error messages?

If you have any questions or needing further assistance, then please contact me.
