Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.


Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

My TV shuts itself down by itself


Poer supply is the cause of the shutdown and would need to be replaced. These cost around $150 bucks just in parts the labor you would need to find someone that knows just what there doing or you could wind up into the hundreds, Thanks

Tv shuts itself down


This is due to bad caps read here what a cap is www.badcaps.net see you tv is getting hot as normal but the caps cannot stand it any more thus shutting the tv down. The bad caps would be more or less in the power supply unit of this TV. So you can buy a new psu or get it repaired by a expert.

Sony 46" lcd turns off by itself and will not power up again.


Sony TVs come with a one year warranty on parts and labor. Call Sony at 1-800-222-SONY They will find a local company to service this product.

These TVs have a self-diagnostic screen that a tech can access to help solve the problem. Your problem could be any number of things including the fan(s) stopping, the ballast board failing, Q-box issue or none of the above.
