Hello guys
Taking a look at some KNX domotic modules that were toasted due to some kind of electrical failure, I found out 2 weird looking resistors.
Seem to me like some kind of fuse resistor?
After diggin a bit seems like a fuse wirewound resistor wafer or whatever that is
They are very toasted but I think the 5 band colours are RED GOLD BLACK ORANGE ORANGE or the opposite, not sure which is the first band.
The red band is larger than the 4 others, but I dont have much experience with these components.
Also one of the orange... -
Dear reader
I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.
At the moment, I have selected replacements based on the following list of values:
3 x 470uF 10VDC
3 x 4.7uF 35VDC
4 x 47uF 50VDC
8 x 22uF 6.3 VDC
1 x 220uF 6.3VDC
5 x 100uF 6.3VDC

I have a Pioneer PDP-427XD TV, not many hours on it. Bought second hand, I think it must have been a TV used in a meeting room, as it was like new when we got it. No manual, but worked out most of it.
The Problem I have now is it went out with a crack noise, then a blinking LED, if I remember it had 6 flashes.
I had a look and after a bit of hunting around (very frustrating as TV shuts down after a few seconds), I found a Capacitor on the Scan Assy Top Board had cracked and tried its best to meld down. Now, as it happens, I can get to this capacitor, but not the others... -
Hi to all forum members,
This psu (Tiny Tech model ATX 480W) had been installed in a very old Windows XP PC but recently i pulled it out as the pc cannot start. To test it, i jumped the green wire and black wire on the 24 pin connector. The psu fan jerk a bit but not spinning. I used my dmm to check dc voltage on output connector wire, the 5v red wire keeps ticking a bit at around dc1v....then drops and ticking again around 1v. It is the same situation with the 12v yellow wire.
Fyi, i desoldered the secondary side electrolytic cap those over 1000uf... -
I thought I'd throw out some of my personal experiences in the last 12 months with Intel iMacs, 2.5" SATA SSD drives and Fusion drive data recoveries.
As a backgrounder, Apple never fitted a 2.5" SSD's to these iMacs. Apple's SSD option was a system of 32GB NVMe blade drive (NGFF connector) and Seagate 1TB 2.5" HDD, married together in software to become a Fusion drive. Non Fusion systems have just the 1TB Seagate HDD.
So, the most common reason an iMac comes across my bench is because it's either ridiculously slow, or it fails to boot at all. The most...12-18-2024, 10:34 PM
