Question about LG Flatron 775FT 17" CRT Monitor

1 Answer

Monitor flickers Hello I have a flatron ez t730sh CRT monitor. Recently the screen has a strange type of flicker that looks like rain falling sideways across the screen .. or like shadows moving slowly up and down the screen (hard to describe!). I've got the monitor set at 75Hz and have tried lower rates but this doesn't solve the problem. Any ideas?

Re: Monitor flickers

First check whether you didn’t put the Inverter or UPS or any kind of huge power supply which content the big or higher voltage transformer...
Secondly try the degauss button on the front panel of the monitor…
Third thing is CRT’s power supply section capacitor is leakage so you need to change…
(If you know how to remove the parts from the CRT other wise go to the CRT repairer.)

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.

I hope this helps,

A few months ago my LG Flatron L1900R monitor started flickering when I boot up my computer. It has become worse, to the point where it now flickers constantly.

From the information desribed, this means that your CRT monitor is going dead. Unfortuntly, there is no way to stop the flickering unless the monitor was replaced. I hope this has helped

Your monitor supports a maximum resolution of 1280 x 1024. If windows fails to give you the option of changing to this resolution and those below it then please follow these suggestions:

Update your video card drivers, if you don't know the manufacturer of your video card try windows update.

Install the latest drivers for your monitor as well.

LG FLATRON E700SH problem wid it is that .its led is flickering dimmly but screen is black out ..? buta sometime after 20m 45 minutes the monitors starts working .but some time it doesnt.??????????


The picture board on your monitor is malfunctioning, since the power led or button is on, but the screen is black out, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Monitor flashing

I have a similar problem with my screen, same one, 15". For a period of two years it would turn black for an instant and resume functioning. Since two weeks it only flashes the picture for an instant and then turns black again. We opened it up to check the wiring but nothing wrong there. We are 99.99% sure that the problem is in the screen itself and has nothing to do with drivers or anything else in the computer.
If you bought it less than 3 years ago and since it is probably a result of faulty construction, it should fall under warranty (by european law).
I am going to take mine to a repairman tomorrow, i will inform you wether the screen can be repaired or not.
