SOURCE: Blue light goes to Orange blinking no sound no picture Screen on

Hi!

Okay, if the screen is white! First, take apart and check the ribbon like cable that goes from your signal board (where you inputs are plugged in) to the lcd controller (under a small metal plate feed the lcd screen), see if loose and or reset! Secondly you either have a bad signal board or lcd controller!

Hi A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.
You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed. This will cure the problem as they overheat being sat next to a heatsink that gets very hot! Try and change them for the same 3300uf but a higher voltage. Hope this helps

If an authorized service repair center will sell you one. However looking at the reviews you may just want to replace the tv since even service centers have issues repairing the tv.
