Your original problem of failed electrolytic capacitors (common) may be the same one occurring in the replacement if it was a 'pull' from another set.
Normally, depending on the quality of the parts used, these supplies will survive for several years before failing.

If this was in fact removed from another set, it's time to return it if there was any kind of warranty.
If not, the repair cost isn't that great if you have an honest tech in your area.

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

It is a good possibility that you have 1 of your inverter transformers going bad. I wouldn't wait to have it looked at. It can cause more damage if the bad one let's go all together.
