I have a faulty Xbox 1708 controller that had bad corrosion on this ic, I can not find any reference to it on mouser. Can anybody shed some light on to it? Picture attached.

I have a strange issue with a 1708 controller when powered by battery. Wired it works fine, but on battery the light only starts flashing when you press and hold the X button. Once you let go it turns off. I've tried the same batteries on different controllers, and also fresh batteries, to no avail.
Nothing seems off on the board on inspection. Any pointers as to where I might start looking or how to troubleshoot this?
I've traced the battery line to around Q7 and Q6, and everything seems in order up to that point.
I did a search already and haven't found... -
We have a XBOX 1914 controller that has shorted the 3V3 to J2 (aerial connector). If you unplug the aerial, the controller boots and connects. It seems stable without the aerial plugged in but it is not ideal.
The schematic is on https://www.acidmods.com/RDC/XB1/Sch...OME_VALUES.pdf
I have little to no understanding of these RF transmitters and so I am unsure what has failed. Currently, T2 is short on Pins 1 to 2 and RFF2 is also short on Pins 1 to 2. This is how the 3V3 is getting connected to J2, clearly one or both of these components are faulty.... -
My xbox one s died recently and currently it shows no signs of life. I took it apart and did some troubleshooting using board view to do some voltage checks in areas of interest. It doesn't appear to be a dead short since I get 12v on the caps near the cpu and other voltages like 3.3v, 5v, 1.1v as shown on the board file. I didn't check every point as that would take forever. When I look at it from my thermal camera, the Southbridge chip has a little glow on it when plugged into power.
The power switch on the detachable face board seems to be fine when using the multimeter to check....12-04-2024, 03:26 PM -
Firstly I am not a tech. You guys may see mistakes or oversights in my methods so don't be bashful and feel free to post corrections/opinions.
=>Background:
I bought my son a used Xbox One original model: A12-220N1A Rev: 02 with original PSU & 2 controllers 7 years ago. I “modded” the unit placing a 4.5” 12V exhaust fan with a 9v wall wart adapter on top of the vent/fan of the unit. And plugged the Xbox PSU into a Tripplite LTR-600 voltage regulator. Also connected to the Tripplite are a 275w computer tower, an Xbox 360 PSU and a Westinghouse 52” LED TV. ... -
Hello!
i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.
Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?
