Hi folks, i have a audio board that has a chip with part number MCF51JF128VLH thats faulty. Its a 32-bit freescale Microcontroller. My question is, do i need to reprogram it or i can just replace it? The entire system is controlled by this IC. Im just afraid it will come empty with no programs.

Re: Needs advice on replacing a chip
Depending on the cost, I would still replace the old IC with a new one and give it a try so you could safely say you did everything possible to repair the problem to remove any 'What if' questions in your mind.Comment

Re: Needs advice on replacing a chip
The thing is cant find the schematic anywhere in the world except for numark
The chip is widely available but yeah just afraid it will come empty and its useless for me to replace it withou writing the program in it.

Hi. In the process of troubleshooting an MSI GE78HX laptop that does turn on (on its own), turns on the backlight on and off in infinite cycle, turns on RGB keyboard backlight and light bar. The CPU gets hot, and its fan spins.
The laptop charges the battery, turns on charging lights, which leads me to think the EC (ITE5571E) is ok. Laptop has no shorts, apparently. Memory is ok, tried it in another machine. Tried 5 different sticks in this machine as well, does the same. Memory connector seems ok, no pins bent.
First, I am going to try to backup and reflash its BIOS,... -
Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...
