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...

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.)

1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...

Hello everyone !

I am new to this forum and also a begginer/hobbyist in electronics. I have a question about an old AT motherboard model PCChips/Hsin Tech M537 V3.1. It hasnt been powered on for 30 or so years.
I have read that it is not safe to power it on after such a long time because capacitors can suddenly burst. When I inspect capacitors I cant notice any visible damage,leak,corrosion or bulged capacitors.
What are your suggestions ? Replace all capacitors maybe or ?
Thank you in advance for your answers !

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
