I have a 39" LCD TV which has a screen fading problem and using a cheap multimeter ive been able to test half the capacitors and found 1 is bad and figure its worth trying to replace it being so cheap, but the cap is a Samxon 10uF 50v km(m) b4a, thats all the info written on it, and ive been told they are an average brand and sometimes very poor depending on the spec.
I wanted to ask if its ok to use say Rubycon or Panasonic, and if so how do I make sure I get the exact right spec, or even better could someone point me to an example of an alternative.
Ive never done anything like this before but im very keen to learn about it, always been interested in electrics and regret not taking a course when i left school.
Thanks for your advice.

Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue
recently I was handed a family members old NAD C320BEE that they had in their loft for storage for a few years but when powered on it went into power safety mode due to a problem on the protection circuit somewhere before it went into storage I was told it worked fine I found lots of people online talking about how the capasitors are known to be pretty bad in this model and can cause this issue the only problem being I don't have much experience sorting... -
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 hereπ€?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting π.
TV Model: Panasonic TC-P55ST50

Hello,
I have this old (2004?) Altec Lansing ATP3 and i would like to replace the capacitors. I have identified 34 out of the 36 of them as Samxon GR of various capacities and voltages.
I can't find datasheets for the Samxon in any of the following variants:
10000uF 25 v - this one i really want to replace because i suspect it is what causes a dull hum regardless of the volume knob position or if the source is plugged in. I am eyeballing the Rubycon 25PK10000MEFCGC18X35.5 for this purpose. So if i pay a 10x the price part for shipping i might as well go ahead and... -
Hi everyone!
I happened several times, in the search for help from the web, to consult this very interesting forum.
So I decided to sign up and I intend to participate actively by making available my knowledge and experience on the subject, I'm a new user but at the same time I'm old in the sense that I have 4 decades of experience in repairing and designing electronics but above all I'm a great passionate about the subject.
Having said that I come to the gist of my post on the forum as the title suggests.
For my passion for technology I'm now collecting several...
