You may have a defective inverter. The inverter provides the back lighting you need to see video. There is good chance the starting resistors have changed values. It would be best to replace the inverter in your case. I would have to have a schematic to find the bad resistors. Thanks for asking and show a few hands of support.

Take a picture of the back of the tv panel removed and I'll direct you to the inverter - first though grab a flashlight and shin on the screen and if you can see a dark image of whatever you are watching - yes you more than likely need an inverter board. it should be a board that is probably covered with a metal shield that is just about the length of tv from top to bottom. has multiple plugs in it on the side of the tv that is closet to the outer edge of the tv....you can get one off the net...

thanks,

The Sanyo DP42848 television has a problem with poor quality back lights. If there is problem with an inverter or a back light, the back lights will come on for about 2 seconds and then shut off.
I had one that had three bad back lights. I replaced them and it fixed the problem. The TV now comes on and stays on.
Replacing the back lights is a very tricky problem. You have to completely disassemble the entire TV to expose the back lights. The hardest part is removing the LCD glass without damaging the very delicate ribbon cables that connect it to the rest of the TV or cracking the glass.
To test the back lights, you then have to reassemble the television, except without the LCD glass. You can then power up the TV and see which back light are not illuminating.
The back lights are 950 mm long and 3.3 mm wide. There are 12 of them. The ends are coated in a silver paint for conductivity. They are held by metal U-shaped sockets at either end. In the middle of the length of the fluorescent tube is a C-shaped plastic support to hold up the center of the long tubes. This plastic is very brittle and breaks easily. Try to slide the tube to the side thru the plastic support. If you try to spread the support wider and pull the tube foreward, the C-shaped plastic support will break.
I searched for an exact replacement, but I was not successful. The closed I could get was 950 mm long and 3.0 mm wide with wire ends. I purchased these from http://www.ccflwarehouse.com for $25 each. Part number CC30950. I bent the wire ends back and soldered them to the metal sockets. When the 3 bad lights were replaced the Television came on and stayed on.
