No, in a defective panel the pixels would be fully on all the time. Your problem is located in the image processor. You will probably gonna have to replace the entire mainboard.

    Or they might be in the cables that connect the panel to the mainboard - they might be loose or frayed.

    No essential difference between them (yours is a newer model than the above one) so the technology in them is identical. Identical problem = identical cause and way of fixing it.

We just replaced a bad inverter board on a dp42848 42 inch Sanyo TV an there is a dark line one quarter of the way down the screen and a large circular area that is a lighter shade than the rest of the...


A dark horizontal band with edges that gradually brighten (as opposed to a sharp black bar) indicates a fluorescent tube that isn't lighting up properly (check to see if the band lines up with a wire coming from the inverter board to confirm). A normally operating inverter will shut down all of the lamps if it detects a fault in one of them, but perhaps the tube is only weak and not dead.

I'm not sure what the bright patch is - perhaps the LCD was subjected to uneven pressure while you were working on the set (perhaps by being laid down on a bunched-up towel), or something is deforming the back reflector inside the lamp box behind the LCD (maybe one of the screws for the inverter board is too long and actually belongs somewhere else).

Why is my TV picture dim


Hello David
It sounds that the back light inverter board, and back light CCFL lamps to your TV need to be checked. It will be best to contact any service technician, because to check its back light CCFL lamps, you must disassemble the display panel, a very skilled work indeed. If you are sound in electronics, you can check it. If you wish to know more http://electronicshelponline.blogspot.com/ check this link. It has details. Pull up older posts there by its left side bar, or see it in 'Timeslide' option.

Dark picture..not bright picture


The whole point of a webcam is to be able to see the person you are speaking with, and let them see you. When the image broadcasted by your camera is too dark, the person on the viewing end won't see anything but shadows and dark shapes. Learn how to brighten your webcam image so the people you chat with can see you.

Place lamps behind and to the side of the webcam. This casts a light on your face, but the lamps will not wash out the image because they are behind the camera. Turn off lamps that are behind you. You have trouble seeing things when you are looking in the direction of the sun or a light bulb. Your webcam has the same problems. Don't make it stare at a bright light. Open up a white screen on your computer to brighten your face. The white screen will create the brightest possible light from you computer screen and help lighten your webcam image. This option is best when lamps are not available. Open up an empty tab in your Internet browser, or a blank Notepad document, and expand it to the full of your screen. Adjust your webcam settings. The settings available to you will depend on your webcam, but many of them offer a "Brightness" setting that you can increase to lighten your webcam. Open the program that came with your webcam, then look for a "Settings" or "Options" menu. Increase the "Brightness" setting until it has lightened your webcam enough.

Why do i have to have the brightness set at 100% or you cant see the picture


Hello
If baklight CCFL tubes become weak, the brightness will be very weak. Now you can see the picture with least brighness. So it is sure that, the backlight inverter board is working well. Just check the CCFL lamps. For a 37 inch LCD tv may have atleast 14 CCFL lamps. When replacing, do replace all at one time. OK.

The picture on my tv is completely dark, but the sound is working fine. how can i fix the picture? because it's a fairly new tv


Hello
Keep a close look to the screen, and see whether there is any trace of picture on it. If it is there, you can see pale shadow of it moving. If it is there, be sure that the backlight is not there. Thhere is an inverter board to energise the CCFL lamps used as backlight component. If the inverter board got faulty, the CCFL lamps won't light up, and no brightness will be there with LCD TVs. Check it. OK.

LCD TV has sound but no picture.


Shine a small bright light at the screen when on and see if you can see a faint picture in the dark screen. If you can then your backlighting is not functioning due to ccfl (inverter), power supply, or back light lamps.

The picture on my JVC TV is too dark


On the inside of the TV, on the flyback transformer there should be two controls. Turn the one that says "screen" very slowly clockwise while looking at the pix. The pix should get brighter as you turn it up- if you go to far you will see lines in the pix or the TV may shutdown.
