Samsung LN-t375h - Shuts off after a few minutes

I have a Samsung LN-t375h that works fine aside from the fact that it shuts itself off after a few minutes. Any ideas on what this could be?

    I have the same problem with my LN-T3253H. It first happened shortly after I purchased the set. No problem there since it was still under warranty. Was told by the technical support people that they had changed the board altogether. Now it is happening again, but Samsung will not fix it because the set is no longer under warranty. Tough. This TV set was a disappointing purchase after all.

Sometimes components on the circuit boards can become thermo sensitive with age and use.

An experienced tech can troubleshoot for this, locate the defective components, and replace them. Under controled conditions, he will use a technique of using liquid air to cool, and a heat gun to heat.

The fault can be in the power supply, or any of the boards causing a change in the specs, thus causing the supply to go in to the protect mode.

It sounds that the voltage output from its internal power regulator board is not proper. Check it.

Worth It?


It would cost just around the same amount of what the LCD TV is worth. I would get another one.

Tv switches itself off then back on again


It seems that the back light is malfunctioning or needs to be replaced the fact that it turns off after a few seconds indicates that is getting over heated. All LCDs, Plasmas and Projection TVs come with a shut off switch witch will turn of the monitor when a spike on the temperature is detected this is to protect the system from overheating. Now before you think about send it for repair; is it well ventilated? Does air circulates around it? Good luck!
