I'm working on a couple of TNPA5349/TNPA5351 SC/SN boards, and both have shorted 30F131s – Q401 & Q402, Q421 & Q422. But there are additional pads, unused, marked Q403 & Q423. I don't have a schematic, but they look like they are in the circuit the same as the aforementioned pairs of 30F131s. Has anyone installed 30F131s on these pads (adding the resistors, of course) and increased the longevity of the repair with three 30F131s in the circuit? I've read that the board will work with only one 30F131 in the circuit. I've also just read about damaged pads on one, bypassing it, and installing transistor on the adjacent pad. What about adding one for a total of three?

I bought a used HP EliteOne 800 G2 All in One PC, that has an i5 6500 in it with BIOS updates going into 2023. The Chipset in the AIO is a Q170, so in theory it should support 7th gen.
HP site only shows a few 6th gen supported, when i inserted an i7 7700k (dead mem. A channel, but would be good in the AIO since i can just put a single 16GB stick in there) with the newest 2.60 bios, the AIO powered on and beeped/flashed an error code for the RAM (3 long 2 short) in the first ram slot and in the other slot it powered on, restarted and then stayed on a blank screen.

I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.
To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.
I have opened the camera and I think there is enough room to add something inside to accomplish this:
The camera is powered by a 3.7V nominal single cell lithium ion battery.
So I need to connect another battery in... -

Hi,
I'm having problems with my plasma Panasonic p42txu32e. The issue started about 12 months ago.
I have a remote controlled main outlet so whenever I turn off the TV set at night, I also switch off the whole power outlet.
It gives me a better feeling to know I don't have 230V on any cables, so my dog can't get hurt if he gets the idea to start chewing on something.
About 12 months ago the TV started to have the following problem: when pressing anything on the RC to get it on, the red led would go off.
Sometimes it would turn... -
Hello my friends i hope you can help me, i have just replace a keyboard with non backlight on a Asus X415 Laptop and i already install a Keyboard with backlight, the motherboard has the conector and ic's to control the light but i doens't work, i already try with a new installation of Windows and it's the same and injecting 3v/5v to the backlight flex it turns on the light, i think must be disable on Bios or need a jumper configuration.
