I was wondering if it is safe to different colours of sharpie markers to mark bad caps and the good caps to replace them so you can make sure you replace it with a cap marked with a dot of the same color, to ensure they all match properly, or would the ink potentially damage the metal on the top?

Never had a problem. Ink is alcohol based and is dry in seconds. Won't eat the aluminum. The manufacturers do it too.veritas odium parit -
Re: Is this safe to do?
no problem.i even sign boards i have repaired with a oddball paint pen.
an easy way to keep track is to pull/replace all of one type in a stage.all 1000/6.3 on the board at once.Comment

Re: Is this safe to do?
Ditto. I use permanent marker to mark the checked capacitor as bad so I know which to replace. For example infamous mitsubishi and hitachi TV in the CRT days.

Hello,
I have a CFI-1215A PS5 (EDM-030 board) here that won't boot normally. It currently will immediately boot into Safe Mode upon power button press with a screen that says "Processing" and then a progress bar that usually begins around 75-84% and slowly climbs up to 99% where it will hang forever. The console will not ever escape past the 99% mark.
Things I have tried:
1. Tried force booting into Safe Mode by pressing and holding power button for 2 beeps so I could use a reinstallation USB, but the console still boots into Safe Mode with the... -
I am trying to fix a broken plasma TV by replacing a large cap on the power board. It is a 1900uf 220v cap and I could only find one place that sells them. It was listed as through hole, so I bought it. It showed up today, but instead of through hole, it has spade connectors.
Would it be safe to get some heavy duty wire (like lamp cord wire), connect that to spade connectors, connect them to the spades on the cap, and run the other ends of the wire 2-3 inches to the holes and then through the holes and solder them in place? I actually did it already and put it together but... -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
Rubycon YK DataSheet (b... -
I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.
As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.
What is your advice/opinion on whether or not on old(er)... -
