When I looked into the vents of a Topfield TF4000PVRt at an electronics store, I saw Samxon electrolytic capacitors in the power supply. There appears to be no known failures of this brand of capacitor. Does anyone have pictures of this power supply (with series of the capacitors as well)?

My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics. -

That's a capacitor from a DVD player, not a PSU.Originally posted by Per HanssonComment

hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I've had great luck repairing computer monitors and LCDs made in the 2000s when CFL backlights were the only option. In most cases it was easy to see leaking capacitors on the power supply and replace them, and at least 5 out of 6 displays were fixed successfully this way. I've recently taken apart a couple LED backlit TVs, expecting to continue my success, only to find capacitors that look completely fine. Is it still worth trying replacing them? Or are LED TVs, because of their lower power demands, no longer killing power supplies (or maybe caps have gotten a lot better)?

I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be... -
I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
