can anyone help identify the smd cap in my final pic above. I need to buy a replacement but cant seem to find anyone that stocks one with the same code on it. For ref, it says 3N, 220 16V on it.
Any help appreciated.

UPDATE: So after working on this on and off for a week and this being my first soldering job I'm pleased to report that I changed all of the caps that Abu recommended on the PSU and my box is ALIVE!!!! I cant believe it.
So in total I've desoldered and soldered on 8 new caps. I even ended up burning the pads on C30 so I thought I was sunk, but after doing some reading, I was able to bypass them by soldering wire to the cap legs and then to the next component on the trace. It probably isnt the neatest but it does the job.
If that was t enough, I then managed to knock off an SMC on the main board while trying to remove the power connector via its clip. To my surprise the box still boots. The only thing not working is the channel up/down buttons on the front of the box. I'll need those for image updates so will attempt to solder on a new SMC soon. Photos below including my new 'helping hands' which was a godsend. Thanks to everyone for their help!

UPDATE: So...the IPA came today. I cleaned off all the residue but there is still nothing on the display and the almost chirpy electrical noise still persists. Next stop is to change all the caps that Abu Baniaz changed above.. Wish me luck!

Hi Guys,
I have the same issue with my LX3. No display on the screen. Only sign of life is when I turn the power switch on it makes what can only be described as an electrical noise from the PSU. Upon opening, I noticed that C29 as per Abu's picture above was bulging. I am a total noob at soldering but decided I would have a go at changing the cap anyway. All I could find was a 1000uf 63v cap to replace the 1000uf 25v cap that had gone (is this too big??!!). Even though it was a little bigger, I managed to get it on ok but the box still does not power on and I have the same electrical noise.
None of the other caps look bad but I have noticed some sort of powdery residue on the bottom of the board (around R10) as you can see in the pic I've uploaded. Is this just normal from the factory or has something leaked? I've bought some IPA to try and get that cleaned up. If that still doesn't work, I guess as a last try I will replace the other caps that Abu did to hopefully get it working. It would be a massive shame to lose this box. Will keep you guys posted.
Any advice welcome
