Are most or all the fuses found on LCD/Plasma PSU's primarily the ceramic slow blow style? I've seen very few with the glass style fuses and mostly see the white ones. Any suggestions or preference where I should order from? I've always gotten my caps from Mouser and I hate to order just one or two of anything. I usually order caps by 10 or more but didn't want to buy bulk fuses and not be able to use them down the road. Appreciate your thoughts once again!

Re: Power Supply Fuse Question
Ceramic body fuse will not shatter like glass body fuse when encounter high interrupting situation, UL probably require them to use when it went through the compliance testing, otherwise they would have used glass body fuse which is cheaper.

TE Circuit Protection offers the widest selection of surface-mount fuses available for addressing a broad range of overcurrent protection applications. Helping to prevent costly damage and promote a safe environment for electronic and electrical equipment, our single-use chip fuses provide performance stability to support applications with current ratings from .5A up to 20A.
TE Circuit Protection also offers the telecom FT600 fuse for telecommunications applications. This telecom fuse helps comply with North American overcurrent protection requirements, including Telcordia, GR-1089,...10-07-2024, 06:07 AM -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.
Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in.... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I found this switching power which has a blowed fuse checked diodes which were still good out of circuit checked main filtering capacitor with an ESR meter 220uf@450 volts 0.15 value which to me seem bad but maybe not but without these items not in the circuit because I have about 8 ohm on the output of the capacitors so I removed the switching power supply transformer and checked it with a ring tester and all but one winding showed good all others either showed two red lights or no lights on and one winding had all lights on which was the only one that was good
One other check that...
