If you turn it on and then get real close and look at the screen from the side. You should see a ghost like tv image. It will be a normal display but just very faint. What has happened is your backlight has failed or the power supply for it. This shouldn't be too expensive to fix as it is a common problem with any lcd tv.

If you have any warranty this will be covered. If not you will need to take it to a repair depot. You can call the store you purchased it from and you can check warranty as well as getting the information for the closest repair depot. Any tv shop can fix this (if you have any of those near you, not as common as they used to be) You can also go to the LG website and look under support for contact numbers. Then call or email LG to get the repair depot information.

As i said this is a simple repair and should be fairly inexpensive say $100. Having said that the usual dvice i give is to get an estimate first and know what a replacement tv is worth. Some simple repairs can cost more than a new tv so its worth being careful.

Hi


Thanks for using FixYa. To start with you'll have to check the Z-sus and the main logic board for any blown components. Also check the Y-sus board. You’ll need to take the back off and check for any blown/bulged capacitors that might have gone bad and causing this issue. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

    If you have already checked the z and y board and also the control board then test the voltages coming from the power supply and also check the connectors.

I have an LG model #60PK750 serial #010RMWV8M569, the other day I was watching and the screen went black and no sound, I did get a display on the screen that said lost signal.


Fixya is a free tech support site. There is mo shop. No replacement parts.
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.

If it works with the 360 and speakers are on---disconnect power from the TV and the box for the uverse and after a wait power them back--its possible a glitch from box if used caused this.

Also if box has audio/video outputs connect from them to a rear input on the set to see what happens.

Hello there , i d like to express my problem here , with the hope to find a solution . I have an LG L1730s monitor for about four years . Recently i had a video card burn and i changed it with a new one ....


Hi
I've repaired a lot of these monitors and every one seemed to do something strange. In this case my first thought is that somehow he monitor firmware got zapped when the card was damaged. Although this could certainly fall into the category of an open ground in the cable. My suggestion at this point would be to take it to a reputable repair person and get their estimate or take a look at www.micromendllc.com.

Screen goes black, while the rest of tv works fine, sound is ok, can change channels.


Back lights are gone or the voltage 2 them is not present. Cheaper to buy a new one.
