True. though doesn't look like any legs were broken.
Blue/Brown = 225ohms
Black/white = 944ohms
Will do, though looks like we might have a receipt here for warranty, so might try getting refund/exchange.
none
Sorry, only saw that components this afternoon & had to Google it.

Oh, I didn't see/test the white (ceramic) fuse (F1), iirc the glass fuse (F2) tested ok.
The big (0-1) switch is on/off. The temperature & timer go up to 9 I think via the soft-press gray buttons
Saw that one, pitty it wasn't the same repair I need lol.
I'm not sure how the wires in the blanket work. There's 4 wires that run into the blanket but none seem to be linked to each when I did a cont test.

Sorry for the delay in response. I've attached two images showing each side. I'm not sure what a 'triac' is, I was hoping for it to be a simple resistor replacement lol, guess I'll have to weigh up trying to fix or whether it's best to scrap it. I'll have a look for some shorts, but in regards to the chip, if the chip can't be identified then I won't know what value to measure at the pin(s), therefor it would make it near impossible to repair, no?
Haha, technically I posted on eevblog first before coming over here, but I like to post of both due to...Leave a comment:

The track they're on is connected to an unknown IC & leads to the main input for the throw-blanket. The only other cap I see is linked to R14 resistor but the capacitor has no value written on it. The blanket/controller that's good is still under warranty & desoldering the cap to check value I can't do. Can these caps be checked in circuit?
Unsure. Was just sitting there & poof. No lightning, no known electricity spikes. Surprisingly I found a review on Amazon with the same controller & the same issue [url]https://www.amazon.co.uk/Homefront-Electric-Blanket-Chocolate-Centimetres/dp/B001IRYFJG[/url]....Leave a comment:

Blown heated blanker controller. Trying to figure out these smd resistors
Hello,
We have one of those heated throw blankets you plug into AC power. The other day it went *bzzzbzzzbbzz... pop*, so I opened it up to find what appears to be two resistors gone *poof*. (R7 & R14 in picture)
luckily, we have a second blanker with what appears to be identical controller, so I opened it up to take a picture
According to the good controller PCB, R7 = 9531, & R14 = 103
Online SMD resistor calculator says
R7 - 9531 = 95.3kohm
R14 - 103 = 10kohm
Is this correct? Would all I need is a 10k... -
Logitech R20 speakers - Replacing one of the speakers.
Hi guys,
I have a set of Logitech R20 speakers, one of the speakers wasn't working, so I took it apart & there was no continuity or Resistance when probing the Tinsel Wires. Plus looks like the speaker was exposed to liquid as there's rust on the metal speaker frame.
Just in case, I removed the other speaker and installed it in place of the damaged speaker to make sure the PCB of the damaged speaker was ok & it seemed to work fine, so it looks like it's just the speaker for now.
Printed on the back of the Logitech speaker is;

Re: Lifted trace, how to glue back down?
Thanks guys. I ended up just sticking the contact in and putting a blog of solder onto each leg & bridging to the resistor. The contacts I cleaned up, pretty beaten up but working.
One thing I noticed, the sticker on the bottom says DC output 1.4v but when I plug in the charger and probe the positive and negative contacts, the left contacts read 1.5v +/- and the right contact 2.3v +/- with voltages fluctuating a bit. I don't know much about chargers, I know they charge batteries at a slightly higher voltage than the batteries...Leave a comment:

Re: Lifted trace, how to glue back down?
I understand soldering the legs together and to the track, but the contact itself would be wobbly. I could pickup some of that UV cure green PCB stuff, or even hot blue & glue down the contact itself from both sides & using a piece of wire, though I'm not sure how secure the contact would be.
So, besides trying some hi-heat resistant epoxy, there's no way of securing a new pad / copper tape to the board itself (that's soldering iron heat resistant)?
Already...Leave a comment:

Re: Lifted trace, how to glue back down?
Thanks everyone for the feedback.
I bumped the pad and it broke off (see attached image)
, so I'll have to try a method of replacing the pad as others suggested.
Hole-to-hole is 4mm, I'm not sure how to properly secure the battery contact. If I use a pad that isn't secured to the board, the contact is going to be loose and possibly pull at the new joint?...Leave a comment:

Hi all,
I have a PCB and one of the tracks lifted. I tried using superglue but no good, didn't stick.
What have you had success with at gluing down traces/tracks ?... -

Re: Small Eiger LED Torch
Thanks for the feedback guys,
I had the LED + circuit setup outside of the torch body and things seem to go well. I re-installed into the body and it started playing up.
I took it apart again and had a closer look, I noticed on the battery housing, the metal tube connecting the ground to the circle circuit, didn't have as much contact on one side but more on the other (see pictures in link)

Re: Small Eiger LED Torch
Thanks Guys. i tried a new battery ('Activ Energy' from ALDI) but still did the same thing. Interesting information on the batteries though. Are there any recommendations on a particular brand or type (NiMH or other) you would recommend over Alkaline?
The clicker on the back I tested first with continuity. Seemed to test good, though as the LED itself seems ok, I'll resemble and bypass the clicker just to confirm.
Hmmm, thanks eccerr0r. But with...Leave a comment:

Re: Small Eiger LED Torch
ha! thanks stj. Just tried to edit the original post with the updated info. Thanks for getting back to me
Looks like I'll have to tinker with the circuit board now. Will I need to remove all components to properly test? I tried checking the resistor, it started at a figure then dropped down to 0.01, so not sure if there's interference.
Thanks again...

Small Eiger LED Torch
Hopefully this falls under "weird devices".
I have a small torch, nothing special. I tried using it today, but it turned off after a few seconds. This happened a few times. Then the LED inside started to get dim and flicker, then it would go off, then it would come on bright, then off, then on dim and flicker etc... if you get my drift. The battery is a AA 1.5v which works fine.
Now, it won't come on, so thought I'd tear it down and have a tinker. I'm still a novice, so don't really know what I'm doing. I thought I'd try the LED to see if it works (which...Last edited by Widget; 07-22-2023, 09:36 AM.
