I have a Toshiba 32L37753DB in which one led blew in one of the strips, I replaced the whole strip with a new one, worked fine for a matter of weeks and then the same thing happened again, same led. I replaced the strip again, the same thing happened again. Can anyone suggest why this could be happening or have a way to resolve the problem as I have run out of ideas. Thank you

Hi,
It is strange that the LED in the same position keeps failing.
As the LEDs are connected in series in the strip the current is the same for all of them and the LED voltage supply for the strip is divided equally between all of them so it is not excessive current or voltage that is affecting it as it would affect all of them.
Is the LED that always fails closer to the diffuser sheet or anything else? It may be that it is getting too hot and then fails because the heat cannot escape from it as readily as from the others.
