Samsung UE55H8000SZ with TCON BN41-02112A

by michdundee

Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele

Microsoft Surface Pro 4 (1724) SEMM remove from BIOS/UEFI dump

by GeryMix

Hello everyone!
I have a surface pro 4 (1724) with corporate management set up (in this case, I understand it's called SEMM). In the operating system installer (Pro version), after connecting to Wi-Fi, it asks me to enter the company system. If I don't sign in, it won't let me continue (similar to enterprise enrollment on chromebooks). This can be avoided if I install the Home version instead of Pro, and then upgrade to the pro version, but this is not very elegant. I would like the machine to be as it should be in factory condition. That's why I would like someone to remove this restriction...

HP X2 1012 G2 Type-C problem

by pc boy

Hi everyone. An HP X2 1012 G2 came the other day. The problem was that the device drained the battery while off. I checked and saw the current is 0.2 before start. I went and checked parts on the MB and saw that the JHL6340 IC that is responsible for controlling Type-C gets hot. Everything worked fine and I checked charging and data of type-C both were OK. I went ahead and replaced the JHL6340. Now it does not get hot, no current before start, charging is OK, but the data of type-c is lost. I mean any type-c device like flash memory or hdmi adapter etc. do not work. I tried another jhl6340 and...

Trying to get a device for EMMC repair, and it's very difficult to lookup all the words to find if I'm on the right track lol.

Trying to reprogram EMMC on Sony/Hisense mainly but would like to hit a few other brands.

My question is would either of these work? And is there a specific card reader I need for TV emmc? There is like 10-40 additional pieces that I can get but not sure what I actually need for my application only.

I may do eeprom as well. Can someone point...
