Re: monitor problem

Your request for the exact problem will require a signal injector and use of an oscilloscope or even more test equipment. One possible cause is the contrast set to minimum.

LG L222WS half bottom screen white

There is a problem with the capacitors in your monitor. This is a normal problem these days with flat screen monitors, I am trying to find out why it is always like tha. This will normally be caused by improper shut down or power fluctuations in your monitor. Capacitrs in your monitor are responsible for holding down the power from the supply, fr the proper display on your monitor. If a capacitor is damaged, or buldged, it no longer holds power long enough for your display, and that is why your screen goes black after a few seconds. This can be solved by opening up your monitor, using a sharp and flat object, opening it starting from the bottom working your way up until the cover is completely out. You will notice finger-like clips that are holding the two covers together. Once you are done, check on the circut board where you connect the power cable.... that is where you are going to find the damaged capacitor(s). You can identify them by noting their bulged head or if there is any liquid coming out of it. Before you replace the, take note of the polarity (+) and (-) so that whenever you replace with the new one it is in the same direction. This will fix up your problem. Note: make sure you let a Computer Technician to do this for you, unless you can do it yourself without damaging the monitor. Thank you

Brightness and contrast increases suddenly

Check following:
1- VGA chord; is it loose or faulty?
2- Power Supply section not regulating perfectly.
3- Supply line from SMPS/Regulator power supply to EHT.
4- Brightness lines and controls (Resitance may be dry soldered or burnt)
5-Pin connection on rounded board of CRT neck may be loosed, Check it if loose than fit properly.
6- Adjust the precet for accelearting and focusing anode externaly fixed with EHT if inbuilt in EHT than only solution is to replace the EHT only.

Monitor : no display and blue led light is blinking

The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.
