90 percent of the problems with flat panels comes down the power supply board. Without this actually in my shop there is no way to know for sure but I would try that. If you take the back off you will find the main PS board. Get the numbers off of the board and do a search for the replacement. A great resource for this is Allied Electronics. I use them all the time. The price of the board should be pretty inexpensive so no losing much if you try it out. Good luck.

Wavy horizontal lines across the screen


It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

While watching an HD program live or recorded when paused picture goes dark after 10 seconds then comes back on after 30 seconds. Does not happen when watching SD programs. TV is new.


sounds like its simply just your tv's auto screen saver or another program along those lines its helps prevent burn in and other issues caused by leaving your tv with still images ok :) dont fret

Picture is stretched on wide screen a circle looks egg shape


Hello
This is an issue because most television programming is produced in a 4:3 aspect ratio. The minority of programming is high definition, which is produced in a 16:9 aspect ratio. Because televisions are made in either a standard (4:3) or widescreen (16:9) format, there is always a conflict with an image being stretched vertically or horizontally. In the case of widescreen televisions, the stretching is horizontal.
Picture Modes
Luckily, most if not all widescreen televisions have a picture mode that allows the user to toggle between a wide (16:9) and standard (4:3) mode. This means that a person can watch non-HD programming in the 4:3 picture mode, and then go to widescreen when watching HD programming. Some TVs have a picture mode that will automatically adjust to the correct aspect ratio. Other people will watch all programming in the wide picture mode, and learn to adjust to watching a stretched picture.
A stretched picture is when a 4:3 image is pulled on the sides to fill the entire screen. People and images end up looking fatter/wider and shorter.
So, what's the big deal?
Some people don't like a 4:3 picture stretched or distorted because it does reduce the overall visual and picture quality. Some people don't like the bars on the side of the screen when a widescreen is in a standard (4:3) picture mode because it looks different.
Solution
There is no fix-all solution for this issue, unless you own a TV that will automatically adjust to the intended aspect ratio. The stretching of the picture is a side-effect, the price we are paying for the better resolution that is digital and high definition. This is definitely something to consider when buying a television, but keep in mind that there is no right or wrong within this issue. It is just the way it is, and there is no way around it unless you buy a 4:3 aspect ratio television.
Hope these lines will clear the issue, if so do rate the solution

Darkened image


same for you, please red this: "My camera is 2 years old. 6 months ago horizontal lines began appearing in all pictures" The problem is not the sensor as the first solution has been posted, the real problem is connected with the flat cable inside lenses that is broken. You cannot replace it, you can raplace intere zoom. The problem is frequently on this type of camera and direct connected with camera frequent use. The fixed and automatic diaphragm do not work bacause broken flet is broken and the sensor is receiving too mach light. Take the camera, switch it on then light with a flashlight the lens, you see a diaphragm movement or hear a click on the lens, if not the flat wire is broken (means microcut inside flat invisible without a magnifying glass). Most time same problem is present with no image on the screen because diaphragm is completelly closed.

WD-52525 screen is jumping all around with wavy horizontal lines etc.


Good Day;

Keep talking to the factory, it is their product. Best Buy won't replace unless it is deemed not repairable and/or terms of the contract. You purchased the extra warranty because you most have felt that the TV might break down. Well, it did, now use the contract to repair your TV.

Good Luck, big IRISH.
