Hi Group
Have the above tv which is working ok but has an anoying buzzing noise
I've removed the back and found the noise is coming from both invertor boards............little hum also from the psu.
Is the fault most likely to be the invertors or the psu under too much load from them..ie a psu fault ?
Thanks John
