Re: identifying backlight fuse in v14 ada type 82C6
What you circled is a capacitor, F2 could be around 2~3 amp, what are the markings on it? -

As already posted in another thread you can find the part with the schematic and boardview https://www.badcaps.net/forum/showth...hlight=v14+ada

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 upgraded display from HD to UHD recently, and I think I did everything right, battery was disabled in BIOS, and removed, yet the screen has no backlight. Both the old and new display behave the same way. I checked the motherboard and I see the fv1 fuse, and a fv2 spot for a fuse, but it's missing. Does anyone have any information on whether fv2 is responsible for backlight, or why it's missing? There's a schematic posted somewhere on this forum, but I can't view it as I don't have the hardware right now, since the laptop screen is broken and I run Linux.
Also from further search... -
HP Modelnumber: 14-dh0061nb​
This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
All these 3 batteries are charging... -
I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.
On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off... -
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...
