LCD screens don't like pressure on them from direct contact! You're lucky it still works at all.

Why does my sanyo dp46848 screen go dark but whites are too bright?


First try to gently push the cable between the main board and the LCD controller (T-CON) board and if that doesn't affect the image then replace the T-con board.

Television comes on and then screen goes very dark. We have been able to check the menu contrast, tint, brightness, etc, but nothing helps. What do we do now?


most likely a defective Z-SUSTAIN board failure if the video looks somewhat correct and the tv is just dark. the Z-SUSTAIN board basically powers the plasma panel and if it fails a certain way it will cause this problem with the dark video. if you can get the tv taken apart and look for part numbers off of the board on the far right looking from that back then you may be able to find the part on the internet somewhere otherwise Contact Sanyo Manufacturing Corp 1-800-877-5032. good luck

I am trying to help my neighbor. She has a Sanyo flat screen tv Model DS20930. The picture she gets is a thin line across the center of the screen.


Hello
Set the brightness, contrast and colour control of that TV to minimum. Watch it in a dark room whether ther are thin white lines across the screen, at about an inch apart, from bottom to top of the screen. If there are lines, that TV needs screen control adjustments. That is, now the screen voltage given to the picture tube went high to some reasons. If you have confidence that you can adjust it, I will guide you.
Open the back cover of that TV. Locate the LOT [Line output Transformer], usually one red thick wire is connected to the top of the picture tube with the help of a rubber ****** and clip. In most TVs it can be located and can be seen as the back cover opened. There are two variable control, fitted, integrated to LOT. Normally the upper one is marked as focus, and the lower one is marked as screen. You shoud adjust this control to avoid these lines.
It is a live service, that is the TV must be switched on during this time, and take causion in every respect not hurt by yoursef and the TV. Keep the children away from you, and an other adult person beside you is better. A liitle turn counterclockwise will remove this problem.

Sanyo Hd T.V. has lost all red pixels.


That sounds like a circuit board problem. Not a very common problem either. Most likely you will need to replace your video board, as that is where the color control is located. It could be a power supply problem to the plasma grid if you are running a plasma tv. Otherwise it can only be the video board. Call a tech for an estimate (most likely a 500-1000 dollar repair)

Very dark picture on TV


Try restoring all factory settings. On your remote, press the reset button twice. If that doesn't correct it, then you'll probably need a repair technician. For more info, consult your owners manual, which is also available at
