This is not true, if you have the Bitlocker key you can move a drive to another machine to decrypt it, it doesn't store the MAC. I have done it several times.

The Bitlocker key is linked to the...

What is it you're wanting to do ? It's a Westen Digital Cloud drive, there is no "i" in it.

Re: SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.

If only there was a way we could visually confirm what is going on in that area.

It's poor consumer law/vendors you have over there. Some vendors sell their TVs with a 6 year warranty.

Re: SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.

The two voltages I asked for a diagnostic points. The 0V indicates a panel fault and that is the part LG would replace.

They are test points that indicate where the fault it. 0v tells us it's the panel.
The panel to LG is the replaceable part so it's on the driver board or panel.

There were two test points next to the connector, you have given one, I don't think you have given the other.

I suspect the fault is in the panel or on one of the driver boards.

The ICs, what are they on the driver boards ? Not the Winbond.

Check it over for dry joints, you might not need to replace it.

Re: Philips TV 40PFL3148H/12 keeps restarting on the logo

There's not much point buying an empty chip, it needs fresh contents programming in first.

Re: Philips TV 40PFL3148H/12 keeps restarting on the logo

I would think it's failed physically with to many bad blocks.
You have tried the only way to repair it without replacing it.

Rebooting after the logo suggests faulty NAND.

Re: SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.

Looking closer there are some test points, the voltage conversion is usually done on the tcon but this is done on the mainboard.

Driver/panel whatever they are called. Why would 12v be going to them, there doesn't seem anything to drive.

The other voltage? The lack of coils on the driver boards suggests there won't be 12v on there.

Re: SAMSUNG UN50TU8000F rebooting, backlight ok. No 12v to panel boards.

Remove the cable between the power supply and mainboard, do the back lights come one and stay on ?
If yes, what are the two voltages on the test points next to the backlight connector ?

Re: PS4 CUH-2115B Slim All Controllers Do Not Sync By Bluetooth or USB

It looks more like a USB issue than a sync issue.
Someone diagnosing the same issue on a slim.
