Some random UPS APC simple repair job – no DC charging – failed capacitor, after replace working perfect.

They are very old photo and i don’t remember what king of model it was…

One of weirdest and simplest repair – not properly fitted DIL IC pulled out by ghost?!

Here are pictures of weirdest repair job i had…

I had not working FDD midi drive, after opening i found EPROM not properly fitted inside socket…

They are hard to pull out and enclosure was sealed so nobody tampered it…

I can’t imagine how much “G Force”  should be apply to lift that ic from socked… of course enclosure don’t show any sights of shock / drop.

After pressing it down, everything start working correctly…

Teardown battery PMNN4104A for Motorola DP3600 radio

I opened PMNN4104A NiMH 7,2V battery used in Motorola DP3600 thinking about replacement cells inside for Eneloop but opening was almost impossible without damaging inside circuitry and plastic enclosure.

In my opinion it’s unfixable / not worth of fixing . See pictures and video for Yourself.

Fixing PHILIPS HF3451 Wake-up Light clock backup battery (capacitor)

From some time, my great Philips Wake-up Light start suffering from resetting clock time after short power loss.  I remember that some time ago, when unplugged in power loss occurred after power back clock time was continued. It clear indicate problem with backup battery. I decide to open and investigate.

Inside i found not a single use backup battery but capacitor. Over time it’s lost capacity.

I do not have spare so decided to order new one from bay.
