Re: LG L1520B

If you keep any magnetic/electro magnetic objects near the monitor these kind of problem may occur, Example Speakers, mobiles.etc.,

But in you case, i hope the problem is with the hardware, Please change the Main Filter capacitor in SMPS of your monitor.

Note: It is not advisable to open the cover of the Monitor. Monitor and TVs stores power even they are disconnected so if you are not sure, please get help from a Service Engineer.

This sounds like either a loose lead connection or a corrupt driver, if its looking like a driver fault you can click Start>Run then type 'dxdiag' then hit enter for windows to check drivers. If it's a driver fault unistall driver in add/remove programmes and restart pc, when it finds your graphics card on startup insert your Graphic card cd rom to install driver again.

My crt acer ac512 monitar only centre line view,c"not full view why?

there are several reasons why picture of crt monitors did not display good picture. if your monitor had horizontal line at the center of the screen?...the faulty is in the vertical deflection, check the vertical oscillator also the fusible resistors & capacitors around that section. if there had vertical line at the center of the screen?..check the horizontal deflection, horizontal output transistor also check the YOKE.

It does the same when attached to another PC? Otherwise I would look for caps with domed tops.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Capacitors kit: he can make you a set of caps for you.

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

A vertical white line appears on my LG L1520B 15 monitor

This is a horizontal sync circuit gone.
In English, probably cheaper to replace than repair.
Wouldn't hurt to get a quote if it is free.

Syncmaster 245B Monitor Shivering horizontal lines

Which type of video connector are you using? VGA or DVI?

If you are using VGA, the horizontal line could be due to interference, like from an electric motor (fan) near the video cable.

Other thing to try is to change the refresh rate. In Windows XP: Control panel --> Display Properties --> Settings tab --> Advanced button --> Monitor tab --> Screen refresh rate. The default ot 60Hz for LCD monitors. Bump it up to 75Hz. That could give a clue to the problem or maybe even fix it.

Horizontal lines are appearing and moving acrosss the screen of my View Sonic E50C Monitor...

What is wrong with your monitor is that the Horizontal section is going faulty, the lines you are seeing are the Horizontal Retrace lines, usually invisable in a working unit. It is often a faulty capacitor(s) OR a Diode breaking down.. in the area of the Flyback Transformer. Probably time for a new one unless ya can fix it yaself.
