Black screen of TV

I believe your video card in your tv has failed. Search your Model/Brand and Serial number on Fix ya. Or list the information in your question, so we can narrow down an answer for you. I had the same problem, and through this site was able to replace my video card myself and my tv has been working fine ever since. 2 years or so. The information i found, or users supplied me, lead me to a company where I was able to purchase the card, refurbished and install it with the directions provided with the new card.

Sounds like the back light has gone mate. Unfortunately this usually makes the tv obsolete

Yes,the tv main Tuner signal board it is the problems and the causes it have intermittents shorts in sides.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv main Tuner signal boad for the replacement.

Call for warrenty serviced,u still have warrenty inforced until a year.Ur tv have intermittently signal shutdown before it come throught the Tuner board not,carrying to the LCD Screen to produced a picture.

This model was known for issues with the Y-sustain, Y-drives, and the Z-sustain boards. These boards help process the picture image to the screen.

When one or more of these boards fail, the screen stays black, and you only have audio & on/off.

You could call LG and try to get your TV repaired at a discount if you can convince LG to honor this known issue.

Another issue could be the actual panel has gone bad. The plasma panel in your TV has a two warranty and LG would fix that for free. Well…it would be free as long as it’s not past two years of your date of purchase.

What zip code are you in?

Typically if you have a backlight and no video image it's going to be the T-Con board. We do know it's most likely not the powersupply board because the back light comes on. Could also possibly be the main board, but typically the T-con boards are cheaper and I'd say you got a 70% chance that's the issue. Good luck.

You could have a loose connection in the Horizontal section or something close to the flyback transformer. If you have a soldering iron and look for loose contacts . Then hopefully you won't have to hit it anymore. Good luck

I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.

A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
