I have LG Monitor Studioworks 500G which flickers most of the time.
Actually i am keeping my monitor without it's base round stand.
The screen lools like rain is falling across the screen.

OP described heavy, persistent flicker on an LG StudioWorks 500G and noted the monitor has been used without its round base. Earlier replies from , and correctly pointed at both external causes (settings, cables, interference) and internal faults (intermittent solder joints, failing components). The best approach is a short, ordered isolation workflow that separates simple, safe fixes from dangerous CRT repairs.

First-line checks (safe, inexpensive)

  • Swap the VGA/video cable and try a different PC or laptop. If the flicker follows the PC, suspect the graphics card or driver; if it stays with the monitor, the fault is in the monitor.
  • Set display mode to a CRT-friendly refresh rate (commonly 70–85 Hz) and a standard resolution supported by the monitor. Update/reinstall the video driver while testing.
  • Remove nearby speakers, phones or other magnetic items and power-cycle the monitor so the degauss routine runs. Refit the round base or secure the chassis—mechanical stress from missing support can aggravate intermittent solder joints.

If flicker continues after isolation
Intermittent improvement when the case is tapped, or temporary clearing after degauss, points toward internal faults: dry (cold) solder joints, aging electrolytic capacitors in the power/deflection circuits, or problems in horizontal/vertical output circuitry (which can produce horizontal bars). These are common in CRTs of this vintage.

Safety and next steps
Do not open or attempt internal CRT repair—high-voltage components can be lethal. Given the age of a StudioWorks 500G, compare a professional repair quote (ask the tech to check solder joints and caps) against replacement cost. For further remote diagnosis, useful details are: exact refresh/resolution in use, whether degauss or tapping changes behavior, whether the issue is constant or intermittent, and whether the problem follows the monitor when the video source is swapped.

Hi,
I need more information...

1) When did this problem start ?
2) Did you make any changes (OR) whether any changes were made around the vicinity of your computer location ?
3) Is there a pattern of colors in any particular corner of the screen ?
3) Please provide with any additional information you can.

Thanks.

I didn't change anything.
There is no such colour around the corner.It's OK.
Only flickering
Screen is just jumping with lots of horizontal bar as TV screen shows on low voltage.

Sorry I don't know whether your problem was solved or not.
But the problem you stated is nothing but just a dry sold problem.
Check that when you hit your monitor from any side then sometimes its screen becomes clear and then again became in the previous condition.
Check the Sold on the circuit attached just behind the CRT, I don't know its name but check it out.
ok
Thanking You,

If the monitor flickers, it has to do with the refresh rate of the monitor, go into your monitor properties and adjust and apply until it fixes it, if that doesnt help at all then its a component failure inside it physically, and that means you need a new monitor

I have a problem with my CRT monitor.
It shows a very weak display when it is started when it is degaussed than it shows a proper result i need a complete solution of that problem.
