My emx-mcp61p-avl has power but no display no beep. video card is new and compatible with my motherboard. RAM is new also.


Just because the ram and video card is new does not mean they work. But since you say it has power, I'm assuming it boots up all the way except the screen is not displaying.

If this is a laptop try the steps below.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.



If it is a desktop try the steps below.



Try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor shows the display, then your original monitor is bad. If the Borrowed monitor does and same as your original monitor and does not show a display then your video card has an issue.

Gateway m280 notebook black screen.


Why did you replace the lcd inverter? Were you able to barely see icons on the desktop which is an indication that the lcd inverter is bad? If not, then you need to replace the lcd screen. If you could barely see the icons and you replaced the lcd inverter, then the inverter is bad. Just because the inverter is new does not mean it works. If the video shows on the external monitor, but you can't see anything on the laptop's screen even when you shine a flashlight on it then the lcd screen is bad.

How to open baklit or activate the light


If you're talking about the backlight inside the lcd screen, it would be easier to just replace the lcd screen. Take my word for it.

And how do you know it's the backlight instead of the lcd inverter? Is the screen dark? If so try this:

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Battery level


As Suzaku explained:
A battery icon will show up on the LCD screen of your camera when it is already low and needs recharging. It can be found at the lower right side of your LCD screen. The ready light of your camera will also blink red and your camera will turn off if the battery is exhausted.
NOTE:
The icon will not appear if the batery is sufficient and there is no TECH way of making the icon show until the batt needs charging.
