The set was working just fine. i turned it off one night and i have never been able to turn it back on. the set is about 2 years old, but was only used for about 2 hours at night for about 6 months.
I just finished repairing the same model TV for a friend who had the same problem. My trouble shooting led me to cold solder connections on the flyback transformer. After repairing the connections the TV works just fine.
WARNING: IF YOU ARE NOT EXPERIENCED WORKING ON A TV, TAKE IT TO SOMEONE WHO IS. THERE ARE DANGEROUS HIGH VOLTAGES WHEN THE SET IS OPENED UP.

The problem is in the vertical deflection circuits which is responsible for giving a full picture. Since the set is 8 years old the money would be better spent on a new tv since more frequent break downs in other parts of the set would be more likely due to age.
More than likely it's activating the protection circuitry. Most of the time televisions won't give you a sign of trouble until something actually breaks. One day they work and the next they might not. There could be a problem in the power supply or the scan section which are both internal that would inhibit operation to prevent your set from overheating and causing a problem external to the TV like a fire. If your set is over 10 years old, replace it. If it's quite new but out of warranty then get an estimate at a reliable electronics repair store.
You have an old tv so the best problems are bad capacitors and bad grounds. Have someone pull the board and search for high voltage caps [160volts or 250 volts] with 1 to 4.7 microfarads. Should be two or maybe three and check all grounds. If the 4 amp fuse is good than the above will save your TV.
it is best you buy another set my friend it is not worth fixing the money you have for repairs and the cost for components put it together and you will get a good tv free of repair worries plus with warranty.if you get that set fix bam you take it home then about a week it is back in the work shop again.you will have to spend more money.a 10 year old set is not worth to have it repaired.replace it.good luck my friend.
