Screen does not maximise automatically

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

disappears for a sec and comes again and again.what should i do to
solve this?

To determine if the LCD screen is faulty ot the video card, connect an external monitor to the laptop's video port. Power up the external monitor first and the boot up the laptop. The video image should automatically switch to the external monitor. If you don't get flashes on the monitor then the video card is OK and the fault lies with the LCD screen. Flashes coud be caused by a faulty inverter or a faulty CCFL lamp. A fault is usually easier to diagnose when it is not intermitten.

no this is not the problem of your monitor. sometimes it cames while loading operating system. it useually cames when you hybernet your computer.if you dont shutdown and make hybernate then this will appears in next time while you on your system.

After you turned it on and the screen shut off, check the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If the computer shut down immediately after the monitor shut off, it might be because of fault operating system. Check with another monitor.
Thank you,

Ok we must remember when we setup any device on our PC, one of the many non PnP devices is and LCD Monitor, your PC should always be shutdown before installing a new Monitor. If you did not do this you could have damaged the I/O port on your PC. Not a definite, but possible! When you plug up a monitor or any serial cable while the PC is still on, it is of a low voltage which can casue some issues for you! Sounds like this one is yours!
