    I bought two sanyo DP42746 plasma 42" TV's and guess what, both failed. Now I only get a black screen, no sound or picture. I only get a green light at the bottom. When I disconnect and connect and turn TV on I hear the relay sound but no pic or sound.... No recall, No help from Sanyo customer service, No Nothing......I also think we should sue SANYO!!!

Picture goes black on bottom half of the screen


You have a bad connection to the panel or bad caps on the boards. Not something for the DIY'er. High voltages in plasma sets.

I am a military spouse and I posted a similar problem way back in January 2009, got frustrated and have started a class action on model DP42746 42 inch plasma. There are too many people with the same experience.
Join in on the class action....and get your money back from this horrible company!

No fees or anything to join in on it.

42 inch Plasma TV


who ever told you it was a bulb doesn't know anything about plasma tv's
they don't work like that!
it is a digital video processing board that put out the picture
then there is whats called a back light which highlights the screen and has nothing to do with a bulb
you will need to call a tech to come out to determine the exact problem by doing some test
if you have a warranty then use it , otherwise it going to cost to get it fixed!
sorry about your tv
