Hi,
Does anyone have any schematics from this equipment? Component datasheets, anything!
Thanks!

is it a router? -
Re: Technicolor TG789vac v2
cant find any info yet - technicolour are usually isp supplied junk that has other names on the outside though.
whats wrong with it?Comment

Re: Technicolor TG789vac v2
Actually it is not one unit, most likely, I will receive a batch of equipments to be rapaired and at this point I am researching the most common faulty components.
I already analized and found some, fixed with components from donor equipments that were tested OK, but the main problem here is that there are quite components that I cant find datasheets.
Thanks!Comment

Re: Technicolor TG789vac v2
main parts that fail in routers, electrolytic caps,
and eventually wifi chipsets.
if they have been in a storm then sometimes a transformer or network chip or related ceramic caps
unless they are very high spec - like VDSL2 with atleast 5 gigabit ethernet ports, they arent worth touching.
you can get 5 port VDSL2 routers that are OpenWRT compatable and still new in the box on ebay for about €15
i have a couple.

Re: Technicolor TG789vac v2
When it comes to Lan controller, Wifi controller and CPU, forget about it, BGA with profile needed! Not worth it!
Yes, most fixable parts are LAN port, all ports 1gigabit, dc plug, power button and some smd caps in short circuit.
The second picture, the power circuit, I think it is most likely a transistor, and in the first picture, it's the phone circuit, I think those components are some dc converters.
Anyway, both cases I can't get any datasheets
Any opinion is welcome!

Hi all,
It's gonna be a long intro, so please buckle in, as it's a problem that's been bugging me for several days now. Thanks in advance.
So, I have 2 modems/routers, whatever the proper nomenclature is, one from ISP and one mine. I want to power them via USB-C rather then their original mains adapters (for reasons, that are hard to explain to sane people). Both routers come with 12V/3A mains adapters.
For this purpose I acquired USB-C charger with 250W and 5 ports, 2 of which can supply max 20V/3A. Since 12V isn't a standard PD voltage option (and to future proof,... -
I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be... -

I've been writing a program in Java that is really just a robust front end for the use of GitHiub Gists, providing a nice interface for developers to organize, maintain and access code snippets that we tend to need from time to time in our different projects.
One of the features of the program is the ability for people to share their Gists with others who use the program over a LAN or over the Internet. The program just basically serializes a Java class and encrypts it then wraps it into a UDP datastream and sends it over to another user.
So I decided to implement UPNP... -
