My Sharp Aquos LC-70UD1U TV won't show an image. When I turn the power on, the blue power light goes on for 30 seconds and then the red timer light starts blinking. The picture and sound will not turn on.

OK basically you need screwdrivers to get the back off the set we then carry out a visual check of the inside (I will provide all details )then we decide which board is bad its then ordered and replaced its a plug in unscrew from the chassis board again I will provide more details you need to get as far as getting the back off the set.

Before that let me know if any of the lights in the front of the set are blinking and pausing like 3 blinks pause 3 blinks or if they are continuous
