No picture no sound but the power is on
That kind of problem is very common on all flat panel TV..
If there's no red lite to the front panel of your TV and no picture or sounds..
The problem is totally dead set power supply board (it is commonly found directly connected to the power cord)..
You can buy it online..For specific and easy search you need to get the part # on said power board (part # is usually printed on sticker attach to the board itself)..
Hope it helps...please don't forget to rate my answer..

Follow the solution for service port 'jump start' with a usb plug. Plug your cell phone charger in next to the TV. Touch the metal prongs of the service port with the metal part of the usb until you get a brief 'flash' on the TV. Then turn on the tv set. It takes patience and a flash light to do this, so you can see what your touching, as my husband couldn't get it to work, but I could.
