Looking 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...

Hi Ladies & Gents,
I am currently playing with and old Hikvision DVR for which I do not have the password. Is anyone able to help with the password on this or able to provide a bios flash image without a password?
I would be interested in learning how to find where the password is stored in the bin file so that i know how to do this sort of thing for myself.
DVR Details are:
HIKVISION DS-7204HQHI-SH
DS-80197 Rev 1.0
Serial Number: 556775917

I have a klipsch kda-500 that would turn on and allow me to get into the web management but it was picking up a lot of noise from audio sources so i decided to replace the smd caps on the power supply along with radial one. Some one was in here before me and they basically burned the bottom side of the traces off for the radial cap but i was able to repair it without any real problem. I thought i did a good job sourcing out replacement caps but apparently not and now i can't get the power supply to turn on it just constantly try's to keep turning on. Attached is a picture of the power supply before...04-18-2024, 03:50 PM

Hi,
BIOS update bricked my laptop - after restart the was a prompt to Proceed with ROM flash or Abort. None of 2 options worked - upon restart the same prompt shown.

With crisis file on USB drive the Proceed with ROM option launches recovery - after displaying the current and the new BIOS version, the process terminated immediately with validation error:

I 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?Today, 12:26 PM

What Can I Do To Get Brighter Image...Yesterday, 06:42 PM -
So I purchased a faulty GPU on ebay Palit RTX 3060 .. It had a broken fan ( it did not spin at all )
Long story short , is the PWM control of the Card seems to be intermittantly faulty
Long story
I replaced said fan , seemed to work for a while , until randomly the fan starts spinning at 100% ( around 3.2K RPM ) for no rational reason ( temps and performance are ok ) . Now fan spins , though several times a day the fan decides to run at 100% for several minuites a time .. Then resumes normal operating ..
bear in Mind the card can be cooled sufficiently...Today, 02:30 PM -

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
