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 dmccul2698Hello, My head unit developed strange behaviors so I ran the built-in diagnostic package which returned "No EEProm". The service manual says there is no EEProm connected. I approached Pioneer and they said to swap out the DSP board. All said and good but the DSP board is $860 USD. I am hoping someone can help me
1). Understand the schematic and check the connections between the EEProm and DSP
2). Check the functionality of the EEProm
I don't know if this is the unit's problem but it's a place to start.
I have little to no electronic experience...6 Photos-

by Matthieu vKHello,
I got my hands on a 2e hand 360 s6 vacuuming robot i wish to repair.
Unfortunately, a common (and mine) problem is that the radar, used for navigation is not working.
a second unfortunate thing is these problems seem to have many different causes, from dirty lens, to stuck hairs so it can't move, to broken down radar module to a faulty PWM (mosfet?).
the issue I am dealing with is what I believe to be a faulty PWM.
I have come to this conclusion as this seems to be an issue that others have dealt with also, but I have not found anyone...Yesterday, 05:32 PM -

by pc boyHi 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...Yesterday, 03:34 AM

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 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
