Electronics Repair Questions? Ask an Electronics Technician
Hi there Lawrence and welcome
Can you please remove the power to the TV (so unplug it from the power socket).
Then on the actual TV, hold the power button for 60 seconds then release.
Then wait 10 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly.
Let me know the results please
It is the internal mainboard that has faulted. This is why the audio is cutting out, it will be a faulty capacitor on the board as the usual culprit.
We have ruled the other causes out for this
I am really sorry about this and you are going to have to return the TV to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
