Hi everyone!
Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.
My issue: No backlight.
Model: QE82Q70RAT
Type No: QE82Q70RAT
The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.
So hopefully, I can fix this cheaper.

Greetings and salutations!
I have a device that uses an N32G455RE. Unfortunately, its flash got corrupted. I have a dump of a working chip.
How can I program a specific region of the flash or the whole flash without touching the RAM, option registers, etc.?
I do not have a J-Link debugger and won't buy one, as I am not rich.
I have flashed a Nucleo board with an ST-Link to a J-Link just to find out that the ST-J-Link only supports ST chips.
What would be the cheapest and easiest option to program the Nations chip's flash without touching registers etc.?...Yesterday, 11:51 PM -
I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.
Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.
Any idea what the problem is?05-06-2024, 01:36 PM -
Hi, I would like to share with you small modification to your Bosch tool 12V and 18V chargers.
You can use it for almost all Bosch chargers what I have seen, for example part numbers GAL 18V-20, GAL 18V-40, GAL 1880, GAL 18V-160, AL 1820, AL1115CV, AL1130CV.
Bosch (today also other brands using the same system like Wurth, Fein) does not care if you destroy your batteries, because they can sell you new ones. So the marketing is telling you only about speed of the charging, so you will not wait for your batteries to charge too long. Me as a customer want the tools and batteries...Today, 01:00 PM -
Hi there,
Recently I had a problem with my msi z170a m7 mobo usb c/3.1 port,
The port connects normally but when I transfer data it transfers with full speed (from the pc to the device I'm sending to) but it does not receive with the same speed, to make it simpler, if I plugged a wifi adapter to it, I can upload with full speed but I can't download with the same speed, but if I connected the adapter to different port it downloads at full speed.
I'm not sure if it's a HW problem or a SW one,

Hello all,
I'm working on an Acer Nitro 5 (AN515-54) with motherboard EH5VF LA-501P with a short on the power rail.
I'm just learning board level diagnostic, but here is what I've found so far.
I injected 1.5v to one of the positive leads on the DC jack connector (PJP101) and read about 1.4a to ground.
I felt around for heat and found the MOSFET at PQB12 is rippin hot!
when i pulled the MOSFET from the board the short went away. In my mind it was a faulty MOSFET.
Ordered a replacement and got it installed only to find it gets very hot again and the short returns....Yesterday, 06:07 PM -
