Re: tv comes on then goes out with in a minute
Please check plug or socket of tv for loose or minor sparking.
if it is ok then it is due to loose contact in power supply or problem in your power supply oscillator section in tv.
call tech person to do it
it is not a major problem.

That is definitely a manufacturers error.
If it has been less than a year since you purchased it i would contact them.
They will send you to a service center. If it cant be fixed they will replace your tv.
It is all covered by them.
If it is past a year its honestly not worth fixing it,
You can find name brand 32 inch tv's for less than 250
while fixing it would cost around 150.
