by corrize[FONT=Calibri]Hello, do you know what is this chip or where I can buy it please ? This is a main chip managing voltages : battery voltage in input and outputs are other lower voltages needed by camera.[/FONT]
[FONT=Calibri]I have 6-7 boards with this dead chip, but I cant find replacement parts. There is no brand, the number matching with nothing. The top is brilliant and conductive material (yes and it is ground). It's not a plastic like other chips.[/FONT]

by ryogadan78Hi guys, I have this 2011 iMac A1311 with a strange problem.
Most of the time, when I plug in the power cord, the first of the 4 LED's turn on, but when I press the power switch the LED turns off and iMac won't boot up.
Sometimes, when I unplug and plug the power cord back in, iMac starts up correctly by turning on the 4 LEDs in sequence.
I have already tried a new power supply, but the result does not change. Do you have any suggestions?

by michdundeeHi 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

by rumpumpel1I have a ThinkPad T460p that keeps restarting instead of shutting down. The culprit is the LAN: if it is disabled in the BIOS, the problem is solved. I have already replaced the LAN chip (WGI219LM) twice, done CleanME, flashed another BIOS. Unfortunately all without success. What else can I check?Yesterday, 12:26 PM

by EazyBoneLooking to up my game a little bit, but these programmers seem a bit daunting.
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...04-21-2024, 08:18 AM -
by longnvuReceived a M16 GU603HE-211.ZM16 SN: M8NRKD03147131E that the owner tried to flash the bios himself. Laptop will not do anything. I've uploaded the bin file from the bios chip.
Any help would be appreciated....-
