I have an audio device with two caps around an ic amp JRC2073. I replaced these two caps and the no audio fault remained, however by chance i shorted the exposed caps of these two with a finger each on one hand and got audio. My hand resistance was about 0.4mohn so i tried large resistor across instead and got audio too, why is this please? All the solder joints look and test good.

i ordered a lot of caps from digikey to repair my xboxs. one thing i ordered was 50NXA10MEFC5X11-ND caps and i think they are not polarized. will this cause any kind of a problem? i really don't want to order new caps just because of this. -
Hello,
I have a laptop that isn't turning on. When I disassemble it and plug in the power connector with the pcb by itself, I can see with a thermal camera I bought that TPS51285A is the only thing getting hot.
So of course, the first thing I do is google the laptop model and the IC, and it just happens that I stumble upon a video by Northridgefix attempting to repair the exact same problem, only for it to catch on fire.
I thought that maybe I'd be lucky so I bought a 1285A, that came in as a 1285B. The only difference I can see between them is that the 1285B... -
I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)
So, here is the... -
I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Hi guys, I have an HP model 15s-eq1040nl main DAOP5FMB6A0 REV:A with a caps/lock 5 long 3 short led flashing problem, I tried to remove the battery and program a new bios and when I restarted it immediately worked correctly, the pc turned on and loaded the operating system.
As soon as I turned off the pc and connected the battery, the problem reappeared... caps/lock 5 long 3 short led flashing again!
the battery was dead, i charged it and it works fine, but the pc won't turn on again.
What do you recommend me? Do I have to redo the bios or is there anything else to check?...
