Had no backlight on this tv. Could see picture with flash light. Getting required power to inverter boards. Replaced the boards and all works great. But I am now trying to find out what was wrong with the inverter boards. Saw some info that there may be a blown smd fuse. Checked them, sure enough the main fuse a smd code D, F1 on board is blown. Going to try replacing it. Question is what could cause it to go in the first place? From the info I found on-line, after most people replaced the fuse the TV was fine from then on.

Re: Toshiba 42HL67US
Can we see a picture of the failed fuse?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -
Re: Toshiba 42HL67US
Here it is. Primary fuse. There are other smaller ones on the board. This is the only one with no continuity. This is the Master board. Slave board all fuses are fine.Attached FilesComment

Re: Toshiba 42HL67US
Seen it often. No apparent cause for it to blow, perhaps under-rated originally.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Toshiba 42HL67US
Thanks for the info. Ordered 10 fuses for $5. Cheap fix to have an extra set of boards or possibly eBay them

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.... -
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...
