Could you please provide the make and model usually found on the back of set?
Is it black on all inputs ie dvd/cable etc?
Is the sound still there?
Hi again Patty
Is the LED (light in the front) blinking if not is it red or green?what is its normal ON color?
or isnt it lit at all?
Im afraid their isnt going to be a do-it-yourself on this set
It is one of 2 things
The powerpack has failed ie their is a voltage rail down most likely the Vs and Ve these are the supply voltages for the X and Y sustain boards
The X and Y sustain boards and or buffers have failed blowing the pico or fusible resistors on the powerpack in turn
Their isnt an easy option with plasmas if something fails theirs a domino effect
Then the firmware would have to be upgraded too
Your best bet is a Sanyo dealer if you give me your zip code I will try and find one for you
