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.

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

Have you written the other voltage on the power supply?

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.

Does the controller work with USB connected ? Detecting 5v is not a guarantee the ports are working.

Re: LG 42LD420 no power

Give the processor some heat, it's an LD series, so there's a good chance its suffering from BGA failure.

Re: Netgear = By far the most horrible support ever!

Netgear has always sold mediocre consumer products, colouring a range grey doesn't really change that IMO.
Their switches were common for having bad caps in the past, i don't know the environment...

Re: Vizio M60-C3 powers on, perfect logo, turns off

It sounds like it could be a BGA issue under the main processor.

Re: Vizio 40” V405-H19 has backlight, no display

There will be different voltages on each on the coils, so it's the middle and right but identify the markings to be sure.

Re: How to flash W25M02GVZEIG chips?

Why not? It is the quickest and easiest way, is it tools or skills lacking?
