Re: want to ground tv to help stop dust
The TV is already ground by being plugged in. Any appliance with current is going to have a magnetic field, and be prone to collect dust.I dont want to sound like some infomercial, but "periodic cleaning" is best, plus cleaning the dust filter on your central heating or air if you have it. You can find some anti-static spray cleaner for LCD's. Make sure you spray it on your lint-free cloth, not on the screen itself.
If you have carpet, it just makes it worse. Maybe you can buy one of those standalone air cleaners/deionizers that remove particles from the air for the room-- they sell them at bed bath and beyond and these places.

Probably not. You can try one of those 'cleaning' CD's that attempt to brush out excess dust, or you could try blowing some canned air in at an angle to encourage any dust inside to exit, but other than that, nothing you can do to fix. If de-dusting fails (and it's not likely to help), the laser or another non-replaceable part inside has failed or gone out of alignment. Do NOT attempt to dissassemble a DVD player yourself (lasers!); you could try a repair shop, but the cost is not practical (a standalone DVD player goes for as little as $25 these days). Good luck to you.
Plasma TVs are difficult to repair. I have not repaired the particular model you ask about. I would certainly pull the power supply board and inspect it for a bad solder ground. Many times this will repair the TV. Be sure to also take a leaf blower to the open back of the TV as well. Dust will act as an insulator, and create extra heat that will break your solder grounds. If worst is to meet worse, you may have a bad Y suspension board. The Y suspension board will take some effort to remove, and if this board is bad, send it in for repair. But let me remind you, the first note of this info is the best effort to fix at any level, and is usually the problem. Also, there may be one bad capacitor on the power supply as well, replace with same value. If you cannot repair this TV yourself, take this info to a TV Tech.Thanks for asking me!
No. Just keep you house clean and vacuum often . Keeping dust and dirt to a minimum is the best way of keeping the fans in the tv from drawing that dust and dirt into the tv. Also cigarette smoke will destroy this type of tv. If you ever get a dark spot in the picture it may be dust on the lense. You can dust the lense with only a microfiber rag.
The best way to clean out inside is to use an air compressor and blow out all dust, or go to the dollar store and buy cheap paint bushes and bush out the dust, then clean mirror and all 3 top of Tube lenses . Make sure TV is unpluged.
The most severe problem dust can cause in an LCD TV is a short circuit. This occurs when dust enters the television's casing and settles on one or more of the internal circuit boards. Enough dust can cause a short circuit, which will prevent the TV from working at all. In other cases, it will damage picture quality or prevent certain features from working properly.
Because a short circuit can only occur when enough dust is present inside the TV, this problem happens after the TV has been in use for a number of years, meaning that it will not be covered under the manufacturer's warranty. In many cases of short circuits, repair is expensive, and you are better off buying a new set.
Dust can also have an effect on an LCD TV's picture quality without entering the LCD's casing. Dust that settles on the surface can distort the picture and decrease its brightness. While it's easy to wipe the dust away, use only a soft cloth and mild cleaning solution to avoid scratching the screen or causing permanent damage with caustic cleansers.
Dust under the screen can be more difficult to clean. Using compressed air to blow the dust out is the best option, short of disassembling the set to clean the screen from the inside. Keeping the surface of the screen free of dust is usually sufficient to prevent dust from getting under the screen.
Another effect dust can have on a an LCD TV occurs when it enters the space around buttons, making it difficult to control the television. On certain sets, dust will cause buttons to stick or prevent them from engaging when pressed. Using compressed air to blow the dust out, or resorting to using only the remote control, will solve this problem.
If you have no idea what you're doing, NEVER open up a TV, especially if you're planning on SOLDERING!
Even after it's been unplugged for several hours, if you touch it in the wrong place you will be knocked on your ***!!!
If you know nothing about TV's you wouldn't know even where to start looking once you opened it up.
Most likely what happened is an accumulation of dust in an high voltage area of the TV was shorting something out, and when you moved it around and tipped it up, some of that dust moved. In particular if someone smokes in the room with the TV, the dust tends to cling more and conduct more.
If ever an energy pike occurs, it would most likely damage the TV for sure. A grounded outlet helps divert power surges to the ground. Sometimes grounded outlets can only handle so much overload, but never 100% guarantee.
Best protection for a flat-screen is a really good surge protector bar. The best ones cost about $100 - $150. Repairing a TV damaged from a power spike would cost about $400 - $600 from a TV repair shop. So, protecting the TV is a good idea considering the cost of repair.
sound like a heating problem and best and easy way to fix that would be to blow out the dust in it, but if it a Power board problem you should have it sent to a tv repair shop. check the dust problem first.
I can just imagine how you feel. Sorry. Our TV, same make and model, just did the same thing today 9/19. Luckily we purchased an extended warranty but however are waiting two weeks for them to show up and who knows what is wrong and how long it will take to fix it?
