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.
Cannot offer solution but my mine has also gone bad. At first a black shadow appeared on the left side of the screen. Took it to the authorized service center. they kept it a few days, said nothing could be done. Used it anyway for the next 5 years when suddenly it went black (or sometimes blue) after working perfectly for the first 5 minutes. A sharp rap next to the right speaker fixed it a few times, but no more. Good luck.
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?
I'm having the same problem with the same TV. I called around to repair shops and I guess it's fixable. Haven't taken it in yet but I was told it most likely is a bad module. But this seems to be a really common problem with this television
Call Samsung they may be willing to cover the repair since it so close the the end of the one year warranty. They are a good company and will usually work with the customer. Any brand of tv can fail and do at any time. Trust me on this. I've seen them do it before.
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.
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.
