We talk about all sorts of service on this forum, so thought I'd try this. My Samsung LCD just quit turning on and I went to the internet to learn more. You wouldn't believe the number of similiar complaints and class action law suits. Anyone have any experience with this problem. Looks like if you own a Samsung--you will have the problem sooner or later.

What model number do you have? And will it not turn on with the remote or the switch on the TV (or both)? I have a Samsung as well but have not had a problem. Mine is a relatively new model.

Samsung built a power backplane on 12volts and used 10volt capacitors, which puff up and fail over time. Select models from about 2005 thru 2009. Look it up on the net under Samsung LCD Problems. The repair boards up until 2010 had the SAME undersized caps. Personal experience with a 46"/120 LCD, with power board changed out twice, under extended warranty, last month!! New boards are 25volt.
If you can handle a soldering iron, the fix is very simple, with maybe $10 of 25volt caps from Radio Shack. Video of the fix on the net also. Very easy.

Hey Mack,
I have lost lots of electronic equipment since I have moved here and I wonder if it's a AL Power problem. Weird things have happened including the voltage going up on the lines. Yes Ihave been using surge protection.
I have a gently used 1998 36" Trinitron Sony that suddenly won't come on. Is it worth fixing? Who could fix it or trouble shoot it?

Model is a LN46A650A, 46" LCD bought in 2008, but according to what I have read so far the problem can affect just about any TV they have made since 2007. Problem is explained as the use of 10 volt capacitors on a 12 volt board. Over time and use the capacitors overheat because they are underrated for the application. A DIY fix is to replace seven capacitors with 25 volt ones. Samsung lost a class action suit on the DLP TVs and are repairing those free, and several Class actions are pending on my problem. I talked to the local warranty service co. and they said that Samsung is treating things on a case by case basis--which means they try their best to deny responsibility. Of course, you have to talk with their fine reps in Bangladesh, or somewhere, so it's a lot of fun. BTW, this TV was also an out-of-box failure when new and it took Samsung over 6 weeks to fix it then. Good luck with your TV--if it starts taking a long time to start up, or it has a high speed audible click and won't start up--welcome to the crowd. Google the problem--ton's of mad folks.
I certainly won't be in the market for another Samsung product.

Yeah, that's what I read and watched the video, too. I plan to take 'em to the wire for free fix. Glad to see they at least have started using stronger caps. I saw on the internet where some people were paying for the repair and still getting the bad boards. Did you buy the extended warranty or did they offer it because of the problem?

as the Rhythm Method. You know? Maybe we'll be OK?? Maybe not.
Junk the Sony. It would cost more to repair than to replace with a better technology, if you can find somebody.
We already had the "Surge Protector" discussion here earlier. I am convinced that a careful look at an Uninterrupted Power Supply (UPS) system is vital for my expensive items, like my computer and the big screen TV, big ticket items.
A UPS puts a battery power supply between the commercial power supply, which bounces around, and your components. Bad stuff that comes down the commercial power line kills the UPS battery and not your $3000 TV. Surge Protectors will not do that.
Check it out.

Bought the TV in 2007 with a 5 year $500 extended warranty.
The first power board failed in 2009 and was replaced with the 10volt caps again. Failed again last month and replaced with the 25volt caps. I checked it to be sure.
Bottom line?? Samsung had a design problem discovered after they began shipping, and tried to hide it, rather than becoming aggresive at fixing it. Shame on them, and good luck finding another manufacturer, foreign or domestic, which will stand behind their products.

I use two, one for the computer + monitor + DSL Modem. The other for the TV + the Satellite DVR in another room. Each is @ $60. Best Buy model 550. Rated for @ 325 watts. Eight AC outlets each with 4 on UPS and 4 surge protected. When AC fails, the UPS holds your computer up long enough for you to shut it down gracefully. Each UPS is about the size of a Kleenex box and weighs about like 2 bricks. Replaceable batteries. Larger units available for more $$$.

Got a Vizio 42" LCD. The price was a good bit less than other more well known brands. Works as advertised. I am no expert with this stuff. I just read all the reviews I can find, and trust. Make a list of the features I need and go shopping. I am suspicious that most TV's are just different packaging of the same LCD panels, and circuit boards, all built by the same suppliers. Maybe not.

What shocked me is a comment a tech from Norman's in Atlanta told me about their life expectancy....5-7 years. That would make it smart to buy the extended warranty like you did.

I have used a larger UPS (1100 VA) on my desktop/monitor/modem for about five years, replaced the batteries last winter - they were about $45 - $50 delivered vs about $140 to replace, so still worth it to stay with the old box. An advantage if you have no backup generator is you can keep your computer active during severe weather. April 27, we never lost DSL at the house, so I monitored much through the computer. Have a smaller UPS on the living room TV/computer and agree - good investment.

My brother had this exact problem. He called Samsung and told them what was happening. They checked their service technician list and there was not one in the area. So, they sent him a FULL refund for the price he paided for the TV. Might want to call them.

technology is changing sooooo fast that a 6 year old piece of electronics is almost obsolete. A leading edge TV that cost $2000-$3000 (or more) 5-7 years ago can now be bought in the $500 range (or less) for similar or better technology. I usually buy electronics that are last years technology at a considerable savings and continue to rotate out the stuff that is 6-8 years old (2-4 years for computers). That way I'm always reasonably up to date at considerable savings....for me, buying an extended warranty doesn't make sense in most cases.

just walked thru Sam's. The same basic TV I bought in 2007 for @ $3000 is sitting there for $800. The 5 year $500 extended warranty bought me Nothing/Nada.

Ex-Telco Engineer here. The Power Rooms of your local Telco are amazing places. Ever wonder why, when power goes out for extended periods, that your non-portable phone still works?? Because they do not actually work directly thru the Commercial AC utility. They power all of the switching gear, even the air conditioners, with Batteries, just like a UPS box. When the AC power goes down, they are already on battery: no pulse/no jump/no dropped calls. When the batteries start to go down, they have a diesel generator outside with a buried fuel tank that fires up to charge the batteries. When the fuel is gone, you are back to smoke signals.
Just trivia for those interested, and that is why your DSL still worked.

Just bought a new Samsung last week. Already have 2 others for about 3 years. No problems yet. Now I'm nervous. Alyhough I must say, I think Samsung's picture is far and away superior to Sony and the rest. And my son's Vizio picture sux.

Vizio does have a "good" picture. But, I think TV displays in the store are deceptive in that the content displayed comes from a source other than cable or satellite. Plus the coax run to each TV is very short. Different situation in your home.
I have a 5 year old Samsung and a new Vizio, with more bells and whistles. Side by side? Samsung.
What's that saying, that opinions are like,,,, I forget.

One of the discriminators between higher end and lower end LCDs is their viewability from places other than straight on. My wife's Samsung picture is as good from the extremes on either side as it is straight on. A Visio we bought for our upstairs office only has a good picture if you are looking at it straight on. Get to the side or below more than a few degrees and the quality drops off dramatically. My daughter's Motorola suffers the same deficiency. My Sony Bravia, like the Samsung, can be viewed from anywhere (about a 179 degree span of perfect picture viewing).
The all seem to do better these days, but when we are shopping for TVs I always get waaay over to one side to check the picture from that angle before even considering the set.

It was the Visio I was watching from the floor, and at the time the room was my wife's sewing room and there wasn't a comfortable chair to be found!!
I can only wish there was reason that would make your question more meaningful.....:>)
