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!

Thanks...

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!...

Yes!...

Hi,

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

Thanks!

Hello,

I own a Samsung LCD tv model le40b530p7wxxc and sometimes when I turn it on there is no image, only sound, I turn it off, wait a moment and when I turn it on again everything is OK. It will only happen when I turn it on.

I manage to check that there is image (with dark room and a flashlight) and the backlight is off.

I opened the tv, checked all caps from power supply/inverter board and they all look good, took out all boards to do a visual inpection and there is no signs of problems.

The problem is pretty random and I couldn't...
