Well I am another one that has joined the club. My LG went out 2 days ago. Watching tv and all of a sudden the screen went blank. Have not been able to turn it on since. Plan on calling customer service today but as it looks by your responses it wont do any good. If they dont fix the problem I can guarantee you I will never by another product by LG.

I have the same problem, I just spoke with LG Customer service. They had me unplug the power cord, hold down the power button for thirty seconds, plug back in and turn it on, this DID NOT work for me, but maybe it will work for you.

Good Luck! Mine is going to a service shop, maybe what they tell me I can post and it will help you if you have not gotten your tv fixed yet!

    Definately will, I have done quite a bit of research, all points back to a bad board, but who knows. I will let you know when I know hopefully this week, I already miss my tv!

    I got NO WHERE with LG!



    They want the original purchase receipt to prove the date I purchased it, from where and for how much... Umm don't have the receipt, they told me without the receipt my only choice would be to Ship this 40 lb paperweight to them, pay the ship cost myself, then an additional 109.00 to diagnose the problem.. THEN additional costs for parts and Labor to repair this unit!



    Are they friggin' kidding me? I did a search via Google and there are hundreds of people having this same issue dating back over 2 years ago, so If my tv is only 1.5 years old, they (LG) must have known about this issue, yet, continued to sell these faulty TV's, they should have recalled them or extended the warranty to 2 years, but I imagine they knew the boards were bad and just "hoped" some were good.



    This is absurd!!!! In my local area (NY) on channel 11 news (WPIX) there is a chance for assistance it is called "Help me Howard" I have contacted them to see if they can help, I encourage everyone to contact LG, make a record of your TV issues, and if you get nowhere, contact Help me Howard, or a local TV show for assistance. Below is what I e-mailed to Help Me Howard.



    Need help with LG Electronics.
    Purchased a LCD 1.5 years ago, it now does not work, I researched online and found numerous, over 100 other consumers having the same issue with the LG LCD TV's posted over 2 years ago, quite a few with the problem being diagnosed as a Bad Circuit Board.

    Phoned LG to try to get the warranty extended as there is only a 1 year warranty, wothout the original purchase receipt they cannot review my case, I do not have the receipt. So they said that I will have to ship this 45 lb tv to them at MY cost, pay 109.00 to diagnose the problem and then pay for parts and labor; even if I did have the receipt I was told they would most likely NOT extend my warranty. So my biggest issue is this, If I can search the internet find numerous complaints of the same issue and I am sure LG was made aware of them YET continued to sell these faulty units after having known they were failing just past a year or even under, why didn't they recall the product, extend all warranties to keep good faith.. something! Not that we all have to repair a poorly made product that they continued to sell. What a ripoff! I can purchase another larger LCD TV for about 400.00 by a reputable company vs. paying an unknown amount, well guaranteed 200 + dollars for LG to diagnose and me to pay to ship this large paperweight... This is not just my issue quite a few consumers have the same. Please help!

Do you have external speakers close to the TV? This may be the cause.
