Re: Worst soldering job ever??
She used Chongs, and it got more amusing when I compared what she'd used against the schematic. The values were fairly random. For example a 4700 where the schematic specified a 1500, and a 25V instead of a 35V. At first I assumed she must have bought a kit, but it looks llke she just went "Right, so I need a big one, two smaller ones and then a really little one". Or maybe she typed in Samsung TV repair kit and got one for a 32" LCD or something. ???
To her credit she did at least manage to put them in the right way round.

Re: Worst soldering job ever??
To update, I've think I've actually managed to get the PSU working! The regulator for the 18V_Amp is shorted which is what was making all the heat. By jumpering PS_ON and VS_ON I managed to get Vs voltage up. Now I've just got to find out why the logic board isn't giving the VS_ON signal itself. Hope the lady hasn't fried it.Comment

Re: Worst soldering job ever??
Damn, that's rough! But you got a single-layer board, thick traces.. easy fix.
Problem with the internet, every man and his dog with a computer has likely heard stories of "them darn capacitors" and can buy an 80 watt (bigger is better, right?) soldering iron from the local hardware store for $5.
Still, hopefully some of these people will learn something...."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi everyone,
I have an HP Elitebook 840 G5 that I am trying to get working again. I've removed the front bios chip (the 32mb one) and have run it through HP unlocker already. I've uploaded and verified the new bin, but am now experiencing an issue that has led me to believe I've been soldering the chip back to the motherboard incorrectly.
Essentially, after re-soldering the chip back into its place and reassembling the laptop, the charging light immediately flashes orange and white and then shifts to a solid white. The capslock and numlock lights blink seven times... -
hello.
A few months ago,I have purchased 0.1mm Soldering Iron Tip of below aliexpress link,But I noticed that It is totally impossible to use this 0.1mm iron tip in the T12 soldering station
https://ko.aliexpress.com/item/4001275635593.html
Is there any good soldering station which is possible to use 900M-TJ-I tip and have inexpensive or reasonable price in aliexpress?
Any reply would be appreciated. -

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...
