Photos 1 & 3: 270uF 35V Capacitors. Photo #2: 390uF 25V capacitors. Odd values for capacitors.Last edited by RukyCon; 05-31-2017, 03:29 AM.I'm not a expert, I'm just doing my best. -
Re: Anyone recognise these?
They're Panasonic, since you didn't bother telling the diameter I can't say the exact series but at least FK,FC,FR have those values. Could be fake ones too.Last edited by aztekk; 05-31-2017, 06:28 PM.Comment

Re: Anyone recognise these?
I feel like i'm being shamed right now...
I do read datasheets.
I've taken apart many electronics new and old and never came across those two values but i have seen other "less common" ones like 150µf, 560µf and 68µf.
The reason why i've have not seen them in datasheets is because if i'm looking for a certain size i end up skipping over all of the others until i find the one i'm looking for.
I feel like i should just leave.Last edited by RukyCon; 06-01-2017, 09:42 AM.I'm not a expert, I'm just doing my best.Comment

Shame is good, builds character!
When you can bend over in the middle of Wal-mart and puke your guts out and not feel shame, you've got enough character. Not until.sigpicThe Sky Is FallingComment

Re: Anyone recognise these?
As a car audio fnatic who does massive builds (6000W RMS, dual 15's in a coupe, etc.) I can tell you that Alpine is one of the best brands out there, right up there with JL Audio (JL is the best, hands down).
The last Alpine amp I had to open was one that was shaken so hard the pins that went from the PCB to the RCA jacks had broken off and shorted out all of the mosfets on one side, killing the amp completely.
However, the build was always amazing. Dual switching transformers, all caps were either Elna, Nichicon or Panasonic, never seen anything else inside them (except for older ones and some of the newer class D ones that have had NCC in them).
I would be extremely surprised if they were fake, especially considering how costly these amps are.
To put the cost of the amp in perspective, their 1000W class D monoblock is ~400$ depending where you get it. A standard class D amp from a brand like SoundStream (who also makes great stuff) is about 150$, both are certified to make their power AND have been tested to make more or over their rated power.
IMO, they're probably real panasonic caps, which wouldn't be anywhere out of the ordinary.
Also, Alpine makes the stereos in higher end Buick cars, and they make the stereos for Jaguar and a few others.Popcorn.Comment

alpine was the high end option in BMW's - not sure if it still is.
low end option was Blaupunkt!!!!!Comment

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 😂.

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... -
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... -
Good day,
I have tried to remove BIOS supervisor password from Panasonic Toughbook CF-33 mk1. Model number CF-33AENABTG, unfortunately I don't have any other info.
I read the BIOS using afuwin, edited it and tried to flash new edited BIOS using afuwin. Unsuccessfully. Afuwin showed "Error: Problem erasing flash." starting with 0x00040000 and stoped. Then I tried many other options to flash BIOS from Windows without any luck. Finally i rebooted the device - and no post. Afterwards I have read the corrupted bios chip (MX25L12873F) using EZP2010 programmer.... -
