Re: Does FB mean fuse also?
Does it have continuity or a burn mark? Probably an smd fuse. -

Re: Does FB mean fuse also?
Whoa!
Dark grey SMD of this type are ferrite that has physical characteriscs that filters DC of (blocks) noise and is NOT a fuse. And does not have a marking on it to state the fuse current rating. Like a letter, or a number even a number with "A" on the end.
Have to be careful with the location marks. I have seen different markings like FSxxx, etc, CV, QV etc, even TVxxx lately that could mean anything for component locations (transistor, resistors, diode etc).

Like these? I stand corrected. They had continuity so I ASSumed.Comment

Just curiosity but do Motherboards have fuses, Anyone
Thanks in advance

Re: Does FB mean fuse also?
I do not know about all the fuses on a motherboard. However I do know any half decent board will have fuses on the USB interface. However some of the cheaper boards do not have fuses and some just use a jumper instead of a fuse.Comment

Re: Does FB mean fuse also?
USB usually have fuse of some types, two types actually. One that is thermal resettable fuses that opens up when it get too much current. Remove current and cools off, conductivity restored. Cheap boards had one time fuse that blows and you are SOL.
The crummiest boards have none and is dangerous to have (insurance adverse and fire hazard).

Re: Does FB mean fuse also?
USB is supposed to be current limited - you shouldn't need a fuse at all.
Of course, very few chipsets have USB that actually adhere to standards....Comment

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 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 all,
picked up this curb alert TV. Looks like the fuse is blown, i don't have a fuse to replace is with, is it safe to short with something just to test it? There is also a burn mark in the white glue near a transistor so maybe the transistor is gone as well. Attached is a picture with the burn circled as well as the fuse that is blown.
Board is labeled as: BN44-00463A
What's my next best steps?
Thanks.... -
Eventually discovered a burn mark near lower corner of LCD. Here is a summary- Backlight on, no image
- Disconnect right buffer board (view from front), left side display comes on
- Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
- Buffer board is pretty simple

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)...
