Question about Sanyo DP42848 LCD TV

1 Answer

How do I fix my TV that will give an image after powering on, and then make it go so dark you can't see it?

When you turn the TV on, everything is normal for about one second. Then the image goes away. The sound continues normally. If you get really close to the TV, like a few inches away, you can sometimes see a picture moving or make out words (we had it on the news). So it is effectively so dark you can't see it, but it is still there. This TV was recently given to us. It was working great in its previous location. It had to be taken down there, brought to our house, and be put up.

This is what happens when the backlighting circuit fails. It can either be the lamp or the inverter board. This is one reason the newer TVs/Monitors are using LED backlighting. They last longer. Typical LCD backlighting can fail in as little as three years if they are left on full time.

    The picture will show for a couple of seconds and looks good but then goes black . Could it just be the board ? And if so how do I know which one it is?

Tv has died


When the TV is on, if you look at the screen and can see dark images, then you will need to replace both the inverters. The inverters drive/power the back light inside the LCD to show the images. You may have to try and different channels and or inputs to truly see if you can see dark images while the TV is on. If you are hearing audio from a channel or an input then you should be able to see the dark images if just the inverters are bad.
If the screen is dead black without any dark images, then typically your LCD screen/module is bad.
If the TV powers up (power supply is good), you have audio and the remote will work with the TV (the main board is good), the only parts left is the inverters or the LCD screen/module.
I can get you LG part numbers if you need them.

Projection TV when turned on picture is dark can view slight images until dinning room light is turned on


Try hooking the TV to a different outlet fed by a different breaker. Does the problem go away? If so, the culprit may be a wiring problem in your house that is causing the TV not to get enough power unless the dining room light is on.If in doubt, consult an electrician to make sure both the dining room light and TV outlet circuits are working properly.

WS-55807: Images are dark on right side of display, but will go away after 3-4 hours.


you could be on the right track get some freeze spray and go around all the parts to see if you can make it act up, same with heatgun or hair dryer when first turned on heat one area at a time to narrow your problem down
