    LG 42PQ30 no picture

    Hello all, I have LG plasma tv with no picture. What I've found so far is that the 5v going into the control board was not present. I suspect the y board is bad but wanting to know if can be trace to a component.

      Yes all the voltage reads correct. I did find the 5v going to the control board. I did notice the led d201 was not blinking or lite on the control board. Control board???

          If all the voltages are there then the control board should be working so yes it could be a control board fault.
