Hi All,
Iv just been given the above TV from my dad as its making a really annoying whining noise so he went and bought a new one. He said to me that the whining noise used to stop after around 15 minutes or so of being on. Now however it doesn't stop at all, I can vary the pitch of the whining by changing the setting of the backlight up or down. Or putting the TV into different picture modes ie sport, cinema etc.
Now my suspicion is its the inverter board(s) having taken the back off and had a look the boards are as below. Now with the exception of this annoying noise the TV is working absolutely fine. Anyone else agree with my diagnosis or have any other ideas on what could cause the noise?
