Open the back cover and check the fuses on Y Sus Board and X Sus Board. If you can find a blown fuse, just replace that board and your problem will be fixed.

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.

I had the same exact problem as posted above. My 50" LG plasma was out of warranty for 1 year! I called the LG executive call center, and they were very helpful. They offered to pay for the parts and labor. They recommended a few local repair shops, and they set everything up for me. The tech came out within 4 days with one part. The tech had to come out one more time the following week, since more parts were needed for the repair. The Y sustain board, along with 2 adjacent parts that are required to be replaced as a set, and the power supply had to be replaced (parts alone cost just over $900). TV is like new again; I'm very happy with how LG handled it, and made what could have been a bad experience a good one.

Plasma -vs- LCD? Pros and Cons

If you're looking into a new TV purchase these days, you have only a few options… Plasma and LCD are major hitters. What follows is this professional’s opinion; you must ultimately do the research yourself.

Plasma TVs
Pros: Exceptional color reproduction. Our eyes have become accustom to viewing TVs with Phosphorus displays. As with TVs of old, Plasma TVs also use Phosphorus to create the beautiful colors our eyes crave. The viewing angle (side to side) and refresh rate (rate at which the image is refreshed) of a Plasma product shines above most other product types. Plasma TVs also have a glass protection screen in front of the panel which can help protect the panel from impact. Prices have fallen recently and have made the Plasma TV a very affordable purchase.

Cons: Energy usage. Using a Plasma TV has been likened to 'leaving the refrigerator door open'. Reliability and longevity are also a factor to consider. Over time, the Plasma panel becomes more sensitive; “Sparkles” or misfiring pixels are common. The Plasma uses many high power components; which, due to failure, have given it a less than reliable stigma. Image retention and image burn are quick to occur. Realistically, 5-7 years of life.

Pros: Light weight and bright picture. Color reproduction has improved by leaps and bounds over the recent years. Some products available do rival the Plasma products in picture quality and reproduction. Cost cuts have also brought the LCD into the price range of many. Energy usage is typically less than that of the Plasma. Image retention is not a major concern for this product. Less parts than a Plasma = Less failure. LCD panel life is estimated to be about 10 years.

Cons: LCD panels use back-lighting systems. Because the 'color' of the light does not change, the color reproduction of the LCD product is not as natural to the eye as the Plasma product.

(Same as LCD TV, with the following exceptions)
Pros: LED back-lighting produces a more Plasma like color response.

Cons: Panel life is about 70% that of the standard LCD products.

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !

Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

Lg plasm TV sound but no picture

Four blinks indicates that there is some fault with its Power Supply Board {PSU}. Visit the site named 'Electro-help' for more details. Click this link.

View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. Some times, the ads attached with each posts, both at the right and bottom, might help you to find the availability of spare parts. There are more than 850 posts to different brand TVs now.

Fauts and rectifications to many brands of Plasmas are described here in detail. Almost all plasma TVs will have the same fault indications, as they are of the same circuit configuration. Only appearance and models will differ.

Have a problem with my 42 plasma, has sound and picture, but picture is distorted/fuzzy. its out of warranty, but was wondering if its worth fixing/changing boards?

To determine what is causing our TV to lose it's picture you would have to do some basic troubleshooting. The areas of concern for that particular model with that issue would be the Power Board, the connectors to the board, fuses on the Y & Z Boards, and so on. Once you have run the tests to determine the parts that need to be replaced you would need to find out the availability of those parts in the area that you are from. The TV is of the age that the cost of repairing it may actually be more than the cost of purchasing a brand new set. Due to downturns in the economy sales of plasma, LCD, and led TV's is much slower than anticipated. This has brought the cost of the new units dramatically.

In closing, do your troubleshooting to identify the parts that need replacing and check their cost and availability. Compare to the local cost of a new TV and that should help you to decide which way to go.

I recently purchased a 47"

Your TV has a light sensor that changes the brightness of the TV based on room brightness.

It's called an "Intelligent Sensor"

You can turn this off in your "Picture" settings.

Congrats on such a nice TV purchase.

If this was helpful, please rank me a 4.

I have a LG Plasma Flat screen TV. I purchased it

With seeing the picture it will be hard fro me to tell what..I am going to guess according to the information you've provided.
It could a buffer or a signal board(s). This TV is only 4 Months old I would call LG and file a warranty claim. LG (800) 243-0000

Best of luck

42" Plasma Cycles on/off when turning tv on

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
