I have this amplifier in the workshop that burns the fuse when I turn it on. What is the procedure to follow since something is short?.Thanks

Re: Technics su-z960 burnt fuse
check the diodes / bridge rectifiers for shorts. -

Re: Technics su-z960 burnt fuse
Queer enough, I just encountered the same problem. I was quite astonished to find the problem in a shorted foil condenser (C702 in the schematic). There are alternative values, mine was a 220nF, 100V type - not enough for the AC peak value of 120V across the condenser. Another source of failure might be the hybrid power amp (IC501, SVI3105B).
Good luck on your repair!Comment

First post -Intel NUC 10i5 -BXNUC10i5FNH not powering on -IC burnt- request for IC details/datasheetHi all,
I came across this very active forum with knowledgeable folks on electronic circuits and components, while google searching for the details of my burnt IC marked 7603 in Intel NUC board. I joined this forum today and this is my first post here.
I recently got an Intel NUC 10i5 and had installed Linux Mint and was using it for about a month when it died suddenly and did not power up after that.(Power Adaptor is ok). When I opened the NUC , there was a burnt IC marked 7603 (and ILCB in second line). I am unable to find the details/datasheet of this IC. I will be grateful if... -
Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
Hi All,
Before replacing what I know to be bad even with my novice experience. What I have checked at the moment is the fuse and the obvious burnt capacitor. I haven't bought any replacement parts yet.
I still have no idea how this happened but could just be plain old turned bad. What other stuff should I consider buying as replacement? thanks in advance.
Edit: I saw that a replacement board can be had for about $50. I would rather attempt to fix before just replacement the board.

Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the... -
Hi guys,
I'm inexperienced with electronics repairs, I've done a little bit of soldering caps and whatnot, but i have a blown fuse on this mimaki printer I got which I have bought a replacement for.
How do I remove this type of fuse (see picture)...it kinda looks like it would pull out of that bracket but it didn't come at first pull and I didn't want to brute force it incase it's soldered on there like most of the rest of the components.
Anybody know how to remove this type of fuse?
(The fuse is toward the bottom of the image labeled F2)...
