Hi my tv comes on for about 10-20 minutes then shuts off. I have to wait awhile to turn it back on but does the same thing again. The first time it happened i waited a couple of days then turned it on and it worked fine for about a week but started doing it again.I tried another plug-in in the house but same thing. House is about 40 years old and hear from girlfriend that shes had the same problem with 2 of her tv's in the last 6 years in this house upstairs and down, could they be related problems with power?.Or something completely different?.

Re: T.V. COMES ON FOR 10 - 20 MINUTES THEN GOES OFF
Well based on your story it seems that your tv when get hot loose some of its contact. i beleive the symptom is cause by a loose solder (cold solder). this is normal especially tv's that are aging. it tends to loose its contact because most of the parts/components of this device are becoming hot when being operated. example of this are resistors, transistors, and ic's(integrated circuits). check the power supply circuits and the horizontal deflection circuits. because these two circuits are responsible for problem you are experiencing. also use a magnifying glass in inspecting the board. based on my experience looking alone without this glass is not enough. you need to magnify it, to see it clearly.
but if you are not inclined with this kind of job, better bring it to a qualified technician.
one more thing, i dont beleive that the house is related with this problem. otherwise all your equipment that are hooked up in it will do the same problem (on and off).
i hope this help you! good luck!

Start simple by using different cables, whether they be HDMI, VGA or standard COAX cables. They could be losing the connection. Also, it's possible the power supply is wearing out and it gets too hot. You might want to simply try some spray air duster type thing to clear out any dust that can make it hot.
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.
Souds like it's way low on coolant. The heater will blow cold air when the cooling system is so low that there is no water (coolant) running through the heater core. Then the thermostat opens, it trys to be normal but the system is low so it gets too hot in just a few minutes. If its that low, there must be a leak somwhere.
try using a master reset to fix this.
Sometimes after being used for awhile electronics tend to malfunction.
press and hold these buttons in this order....
power / volume up / channel down.
The tv should shut off after doing this.
Turn it back on manually.
This will reset the TVs internal memory chip.
I dont guarentee this as a permanent fix....but it worked for me.Good luck
