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 100% verified.

Capacitors change after a little while and their naming scheme too. So let’s take you Elna RJG series. If you look you cannot find that series on any reputable supplier, besides eBay, Amazon and Ali etc. Means that A: they may be some fakes or rejects out there, B: that series migrated at Elna to RJH. Looking at these, they are all low impedance, 105C, 5000hrs rated. Replacements? No problem Panasonic, Nichicon, Rubycon are your friend.
Your tester cannot distinguish between Elna, Panasonic, Nichicon etc. equivalents anyway to be anything meaningful. what does that mean?
You don’t need a ELNA RJG datasheet to see if they are good or bad to troubleshoot an issue. -
panasonic FR should be good.

Thanks for your replies. I have just picked out some Panasonic FR caps which seem to be best suited to this application. The only size I have struggled with is 47uF 10v. They do not make this size in the FR or FM series but do make a 16v cap in the FC series which seems to be my only option. My second choice was one from the Nichicon PW series but they seem to have now discontinued the 47uF 10v and 16v.
Why are the delivery charges so high for Farnell UK? It is free collection for RS but then the caps sometimes only come in bags of 25+Comment

just get the 47uf 25v FR's

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

Hi,
I have capacitors like this one in the photo. There are differences between other Elna series, I attach foto of Elna RE3. On this green capacitors series is not specified! Fake?... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)

I replaced capacitors with aluminum-polymer.

Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.
TV Model: Panasonic TC-P55ST50

(TLDR: It was capacitor C6519 [Koshin KZH 50V22uF] and C6515 [Koshin KZH 25V47uF] on the power supply. I have questions at the end)
Disclaimer: I'm an amateur hobbyist and will get things wrong.
Always use caution when working around mains power and high voltage capacitors!
Hey guys, I'm repairing a Denon AVR X6400h for my brother. It quit powering on after a power outage. It acted like this last time there was an outage, but after letting it sit overnight it started working again for a few years. This time letting it sit did not bring it back.
