Question about Samsung TXM3297HF 32" TV
If you had the flyback replaced recently, the Horizontal output transistor should of been replaced with it also, it works in conjunction with the FB. It may be brakeing down when its under a load. In my years of repairing Televisions If I have to replace the flyback then I also replace the HOT along with, you may even have a bad flyback again, check the pins on the flyback for open or cold solder joints also. Try this also. With power off hit the mute key on the remote, push number keys 182 and then hit power button. This will put the unit in service mode, if after going into service mode the unit turns itself off then you may also have a main power supply problem..

The behavior implies that either a connection is effected by the heat of running or a component is failing under those conditions. It would be helpful to know the following:
1) Make and model of the unit in question here.
2) A description of what you mean by "starts to break up".
The shutdown is occurring because of internal protection circuits that kick in when a problem is detected. This is to prevent further damage. We should be able to provide a more detailed explanation of the problem and possible solutions once the info is posted.
