When it comes to technology, we all know that many things can cause a equipment to fail. When it comes to our beloved Nikon SB-600 there are common issues which result in about the same common problem.
If you haven't come across David Hilos instructions to fix you SB-600 with the symptoms of:
--NO CHARGING SOUND
--NO READY LIGHT
--OBVIOUSLY NO FLASH

Please visit his instructions First before moving to this second or in other words, these Followed instructions if changing your Thermal fuse from David Hilos instructions still don't work.
There are about 4 common issues that can be accounted for. Some more rare than others which i will list.
-- For no Flash>>Broken Flash Bulb or busted FUSE (On Boost Circuit 'TAMURA N4F")
-- NO CHARGING SOUND but READY LIGHT comes on, it may likely be the Main Capacitor.
-- No READY LIGHT>> Busted Mentioned Fuse or Capacitor located on the (L-PCB) Location:"C-104" on the board.
-- No Power up After a sudden Drop>> Its a simple fix which is a Chip named (F100) Located on the (R-PCB) Location "L-301" on the board. For more info on No power up please visit the instructions of David Hilos on the second page of the post and scroll down till you see the comparison of a dropped on and the one that is working right next to it.
In my Case, I went for a photo shoot, and i pull out my Sb-600 and placed the batteries in and turned on the unit to test it. I always do this before any shoots. I noticed that the unit powers on or Boots up but no flash. The charging sound was weak, As if it wanted to charge fully to give me a ready light but couldn't. I then turn it off immediately and pulled the batteries out and noticed they were hot and smelled from burn from the battery compartment. I checked the contacts and they were spanking silver with no signs of burn. I figured right away it was from inside and called it a fried unit.
Now I will show you the Broken "C-104" and where to disassemble to find the (L-PCB)
First and most important remember to discharge your capacitor with at least a 2k ohms Resistor.
Remove these two screws

Then These four screws

Carefully remove the front plate, and remove these four screws. Carefully remove the cables attached, and carefully remove it from the LCD Panel (rear plate)

Then remove these 3 screws, and carefully remove the Battery compartment from the PCB.Be sure not to snap those Black or red Battery cables.
Then look for "C-104" on the (L-PCB) which should be the bottom PCB and if that Capacitor is cracked or burned you will need to replace it. In my case it looked like this.

The space is very small to take this capacitor off. Its your choice if you want to take that L-PCB off to work better but if your skilled at soldering it should come off with a capacitor soldering iron. The Part i used is a Kemet C2225C104KCRACTU 500volts 0.1uF 10% Capacitor.
You can use any capacitor as long as its a high voltage (500volts 0.1uF). In my case, the capacitor was a little over spec by being quite wide but it worked.
This is the Finishing Product.

Thank you for Trying and Good luck!

Also fatigue, you also helped me and my brother in your D80 Err fix thread
