Hi guys
i got a campomatic led tv labeled "32s1j" which have a back light problem: no back light.
i opened it and did some voltage test ,the led driver deliver only 26 v which means that one led or more is fried.
There is two led strips and each one contain six leds.
i changed the fried led and reconnect the two strips and the problem were fixed, the led driver now deliver 70 volt when i press the power button and 26 v in standby button.
i turn the tv on for three hours, after the led strip fried again!!
My assumption is that the current delivered by the driver is to much for the led which caused them to fry(the led strips are not the original ones,they were changed by another shop before i got the tv)
To solve the problem a friend of mine told me that i should access the tv secret service menu to change the brightness of the tv which decrease the current and increase the leds life if that make any sense ??
But i don't know how to do that :-(
