I have researched this problem and it is so common we that own this piece of junk ought to form a class action suit and sue. It is caused by a bad part or bad connections to a part called a backlight inverter. It seems the LCD needs a higher voltage than supplied by the 12vdc power pack so this part re-chops the DC voltage to generate the LCD requirement.

The date of manufacture is on the back of these TVs and all the problems seem to be from those made in 2006 to 2008

If they are visable when the set is off then I would have to say yes there is moisture damage to the LCD panel itself. If visable only when turned on then you have a faulty LCD panel.

It could be the power supply or the short circuits in the backlight inverter board tah caused the power supply to go into the shutdown mode. Those are the two main things to check.

Sound No Picture Sanyo LCD WIDE Screen HDTV


Hello heck75,

I wrote this for another post but it applies here also:
This sounds like your inverter or back-light has gone out. What you can do to test this is to turn the TV on and then turn off all of the lights until the room is dark. Then shine a flashlight at an angle on the screen and see if you can see a picture. If you can the back-light and or inverter has malfunctioned. If this is the case, then I would suggest that you have a qualified TV technician fix this problem, but first ask for a estimate because the inverters and back-lights are sometimes part of the screen and is it is you might as well buy a new TV.

If the inverter is a separate board, If you have a background in electronics you might be able to repair the board, however if you do not have a background in electronics, again I would suggest getting a qualified TV technician to work on your set.

I hope this helps,

Thank you,

Without a model number I gather the TV she threw the remote at is a LCD tv? If so look at replacing the set as the LCD panel is now damaged and usually cost more that what a replacement set will. There is no fixing a damaged LCD panel.
