My t722i display has no back light

When I power up my phone the backlight does not come on, you can see what's on the screen, but the screen is dark. What can be the problem? I've tried the brightness, the contrast setting and nothing. Please help me resolve this problem

    It's November 4th. I bought my LG Chocolate VX8500 phone on October 22 and the backlight has not been working, so I cannot see the screen! When I turn it on, it works until the screen turns off from inactivity. When I slide it open or unlock it, the screen comes back on but the backlight doesn't, so it's dark. I can just barely make out what's on it only if I squint and look really closely and only if I have the right amount of light. I have gone through the display settings and have tried it with the backlight set on "Always on" and with it set to go off after a certain number of seconds, but nothing makes a difference. The phone is two weeks old and it has not been damaged as far as I know of. It starting acting up basically the day after I bought it. I didn't even use it the day I got it because it had half a charge out of the box and I was waiting for the battery to run down completely before I charged it so I left it at home, where nothing could've possibly happened to it, so I cannot think of anything that I might've done to it to cause this. I signed up for the replacement program in case I lost it or it was damaged and not covered by the warranty, so I can get a new one if I need it, but I don't want to do that if there's a way I can get it to work without having to pay to ship it to the company for fixing and without having to buy any replacement parts or anything. The phone is not in my name, so I myself would not be able to get the replacement, and I don't want to bother the account holder with this if it is not neccessary. I'm grasping at straws here, because I think the only thing I can do is get a new one, but, before I do, is there anything that I can do to fix it? Thanks.

    Actactlly the same thing I did. No backlight, everything works fine. I use to give my phone to my 1 year old daughter who just loves to play with it. She keep putting it in the mouth, and I think my problem started due to this.

Clean up the LCD connector first as well as the LCD ribbon w/ lacquer thinner, brush it gently, if nothing happens, replaced it.....

Hi, Issue TCL 55" TV half of screen dark. Model 55ua57-w As mentioned the middle of the screen is dark. Can you suggest what might be the issue?

HI there do check all circuit boards in back cover for any blown fuses or other electronic components , If all good then you will have to remove LCD screen to test LED lights . switch TV on from standby mode and shine a LED torch onto screen with room completely dark if ICONS do display ,Then i wood recommend for you start off checking your power supply circuit board or driver board . A easy way of checking if LED lights are working again in a dark room with TV switched on look through back cover vent holes for any light shinning through small openings this would determine if some or all back LED lights are blown.

What causes a back light from an LCD screen to go dark? I had a Technics PR-305 Digital Piano since 2001.

It can be the backlight itself, or the circuit feeding it, but normally it's the backlight. If you can solder, backlights for most displays are available form Way cheaper than the whole display.

My wife's presario cq60 widescreen laptop has a power problem. For a period of time now, several weeks, on occasion it will simply go dark and nothing lights up. I remove the battery and power cord...

By go dark do you mean it turns off? If not, LED lights on the front of the laptop continue to stay on, but the screen goes dark, this could mean the backlight of the screen is going bad. It might be intermittent, but, a screen consists of two elements, the display itself, and the backlight which is what makes the image bright. If you bring it into a well lit area when it is dark and tilt the screen back and forth, you might see the faint image on the screen. Sadly, screen repairs are expensive, easily exceeding $300 most of the time. It is often a better idea to replace it rather than repair it.

Dell ADAMO 13 w/Vista 64 Random power failure...goes dead in 1 second. Battery fully charged. Happened with external power and when on battery. I have latest BIOS v6.0. I ran pre-boot diagnostics...

If the power totally fails (i.e. power is cut off, LEDs turn off, fans stop, ... etc), then this more likely to be because of a short circuit developing in a failing semiconductor component, or a power supply problem.
However, if the laptop is still running & only the display on its LCD is cut off but the laptop itself stays powered on, then your laptop might be experiencing a failing screen inverter board, a failing screen backlight lamp, or a failing LCD screen cable.


1. When you turn on the laptop, the screen lights up for a short period of time and then goes dark. You still can see an image but it is very dark, almost invisible and definitely not usable. When you restart the laptop, the screen lights up and then goes dark again. The laptop works fine with an external monitor.
2. Your laptop turns on but the screen remains dark all the time. You still can see a very dim image outline. The laptop works fine with an external monitor.
3. The laptop screen works fine for hours or even days, but sometimes it goes very dark as it mentioned above. When you restart the laptop, the screen works fine again.

Inverter failure symptoms are very similar to backlight lamp failure symptoms and in most cases you cannot tell which one is causing the problem until you replace either the inverter board or the backlight lamp. From my personal experience, inverter boards fail more often than backlight lamps. If you have to guess, replace the inverter first.

Monitor goes on then off right away.

The backlight inverter is faulty.
THis means that there is either a loose contact or one of the transistors on the backlight inverter has blown

The screen is dark on my e71; the back light is off

It seems you have a backlight failure. If you can still see the screen on the device (as far as texts and pictures), you would simply need to replace the screen in the device.

LG Shine screen display

replaced the LCDS on the phone

Backlight does not come on

chek display conector pin resolder with mini iron, chenge display too.

Display light is dark

I have seen this problem before this is caused by a failure of the backlight which provides illumination for the LCD screen. You may also want to check the inverter also since it fails often and interacts with the backlight.
