A lot of these sets have a software upgrade that can take care of intermittent power on issues, check with the LG website and see if there is noe available for your model set, I have seen this solve these problems numerous times
Nope. not a common thing. Also, given that the set is only 8 months old, it should be under warranty. Place a call for warranty service. It would help to know when this noise happens too. for example, does it occur right away or only after the set is on for a while? How long must it be on? This type of info will be helpful to the service center in tracking down the problem in the least amount of time.
I have Sanyo TV.
This problem started after I got into a sub menu with choices of volume lock and channel lock.
I accidently set it the volume lock to ON.
I could not go to that menu again.
It seems that this TV has the feature of securing the volume so that the kids can't change it.
Any way to go to the locks sub menu?
Don't feel bad about Mits. All the projection companies and all
the new TVs have markedly poorer reliability than the good old CRT
types. You should see all the class action lawsuits against even
some of the best companies!
The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed
short overloading the supply. They dry
out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.
In short, you need a experianced tech to troubleshoot this.
