Main board is likely the issue or worst case is a defective main screen called a display panel. Voltage checks will not usually help with this type of problem since it will likely have to be traced with a scope.
3-5 years is average life on this type of set and Philips is known for parts at that age becoming unavailable............
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.
LCD TVs 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.
LCD-LED TVs (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.
Likely if picture comes on and is very dark like a black swirling cloud or similar you could have a bad PDP or Plasma Display Panel.
What can happen is the panel is a sealed unit with an inert gas inside---if there is even a tiny rupture inside the panel the gas goes and bingo====very dark screen that is almost impossible to see the picture on.
If this is the case it is fatal as Panel is more than a new set discounting major labor to replace it.
Unfortunately there isn't a menu feature for this on LG LCD tvs..there is on LG plasma tvs. Screen burn is the fate of plasma tvs which is phosphur burn, whereas IMAGE RETENTION is the problem on LCDs after prolonged static image displayed caused by prolonged cell charge polarization. What you could do is connect your PC monitor output to your TV serial input: Create an image that all is white on your PC. Open Paint and create a big size
screen and save it as JPEG.Right click on your
desktop>properties>screen saver tab. Choose my picture slide
show> the settings>browse the picture you made and modify any
settings your prefer your your screen saver. Hope this helps
I presume you have burned in an image from some source? Plasmas are very sensitive to burning in so be careful when hooking up a device that doesn't have pixel shift or dimming. Think about how a DVD player splash screen looks.
You will need some sort of source device that can give you WHITE and BLACK. If you have a VGA input on your plasma (more than likely) hook up a computer to it using the PC input and bring up PowerPoint. Bring up just a blank new presentation. Hit the F5 button or click on the tripod screen button. This will bring up the full display screen, which should be white. If not hit the "W" key on the keyboard. If the burned image shows up as a gray or black image, leave it on for a few minutes and then check it periodically.
f you don't see a burned image when in WHITE mode, hit the "B" key. This will bring up a BLACK screen. Check your screen again. Keep doing ot until the screen is clean. By the way, this will not completely remove all burned in images.
mate thanks for the reply ,yes i still need advice with this,can i just mention one thing first you are asking for payment for advice ie knowledge ? but if ive fixed it you want my knowledge for free ?
Picture burn is caused not only by xbox's, wii's and such, but by regular tv as well (those little insignias in the bottom right hand corner).
Main thing is to turn any brightness controls down to lower levels, and do not leave still images on the screen all the time. As long as the images are moving, then the screens don't "burn".
It's actually similar to the old screen burn in you'd see on very old CRT televisions and monitors. You can play your playstation on it, just make it a point not to leave it on the same screen for long periods. For instance, if you pause the game, turn the TV off until you're ready to continue.
Plasma Burn In only happens if you leave the same image on the screen for an extended period. Just don't do that, and you'll be fine.
Seems like a `Clear screen` instruction or component isnt working.
