How to Hitachi TV Turns on but No Picture or Sound

Recently I have started to do some home fixes for my gadgets before taking it back to the company if the warranty still covers it to get another one or fix the problem for you. The issue with the Hitachi TV which is Hitachi TV turns on but no picture or sound was fixed with a simple reset.

What it means when you turned on your Hitachi TV with no picture and black screen or no sound is that once the Hitachi TV is turned on the screen will remain black and it will produce neither pictures nor sound to know whether the Hitachi LCD TV is working on not.

In most cases, the Hitachi TV picture problem or Hitachi TV sound problem can be fixed using the TV reset option if the problem has nothing to do with the LCD TV power board and mainboard.

If the Hitachi TV turns on but no picture or sound is caused by damaged power board or main board it means that you would have to remove the Hitachi TV panel to change them, however, before we can conclude that the Hitachi TV turns on no sound and picture is caused by the TV power and mainboard let quickly do a check.Hitachi TV turns on but no picture or sound
