I've load tested a few Thermaltake Evo Blue 2.0 750W PSUs recently and will soon be publishing a review on HWI. However, both of them have an odd problem. Normally, the ripple on the -12v rail is very low, around 10mV. But with the PSU loaded between 350 and 450W, it goes through the roof, exceeding 500mV at times. There is also a noticeable increase in the +12V ripple. But it stays in spec. Everything returns to normal when the load is above 450W. My understanding was that the -12V rail isn't used at all on many new PCs, which have no serial ports or PCI slots, and this wouldn't be a problem on such a computer. Is that right? or have I misread that? Also, any ideas what could cause it? I've tried touching up and re flowing several joints, but that didn't help, and I can't find anything else obviously wrong.

I love putting bad caps and flat batteries in fire and watching them explode!!

I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.

I ordered a Bluetooth earbud one and half year ago, and right earbud broke. The light that should have been red when you put it in the charging case started to turn blue continuously(which means earbud is not charging) and after 1 week the earbud completely died. I disassembled right earbud because the warranty finished. I diagnosed the battery was dead, so I charged it with TP4056 and revived the battery.
Right earbud is working now but I still didn't solve charging problem. I checked the charging box with a multimeter. There is 5V. I checked the headphone pins and they are working.... -
