Hi Chinedu,

What about the 5 volt? Is it stable? Is the power LED color remain red or turn to green after the displayhas shutdown?

Hi Chinedu,

Can you confirm if it is plasma tv because I have not seen a 15" plasma tv before and plasma tv does not have inverter board.

dear Mr jestine, I am very happy on the electronics repair newsletter you share with me,it really help me out in repairing electronics,thank you very much. Please I have problem with one 15 inches acoustic solution plasma TV, if you put it to the power supply the red led power indicator will comes up and when you press power button to Bost it ,the screen will flash two or three times and the led indicator will turn on again. i have checked the power supply,12 volts comes out and the same 12volts entered to the inverter board,please what could be the problem?

HI Vinny,

I guess you are referring to optoisolator IC. Do you mean when you power on the TV, B+ voltage came but then drop back to zero volt?
