I have been trying to repair a Samsung TV model LE46C535F1W with a BN94-02616Z main board. When trying to wake it up from suspend, the power led blinks five times and then everything remains off.
Hoping that it would be a power supply issue, I have replaced some of the capacitors on the power supply board. Since that didn't improve things, and after reading that it could be a main board issue, I did some troubleshooting there as well. After spraying the upper right corner (the "power corner") with some freeze spray, it actually turned on! After having narrowed it down quite a bit, it seems to be related to the flash memory (located right above the top-right corner of the heat sink). It does not seem to be related to any passives around the flash memory, but I am not quite sure.
I am curious to hear if anyone has a theory of why it starts working when the flash memory has been cooled down.
Could this be a symptom of something else being defective, which propagates to the flash memory?
Can this be repaired in any way, or will I need to replace the whole card?
Regards,
