Hello everyone. This is my first time in this forum, but I'm registered in some TV repairs forums too. I'm not an electronic technician, but I like to fix my own stuff 😀
I have a JVC KW-M24BT I got from a friend to put in my car but it wasn't working. I opened it and realized it has a damaged IC but couldn't found anything related to its numbers. Couldn't found the repair manual either.
The PCB number is: KW-M24BT MB PCB. 20170726 Ver1.0
The damaged part number is: 734B1 3475A in an 8-pin DIP marked as IC6 on the PCB.
Did some research looking for the part, the PCB or a broken device for parts but without luck.
Any help on this matter? I'm Attaching some pictures too.
Thanks in advance.
Regards

Thank you for The link and fast response! Unfortunately, that and other similar manuals (checked like 6) are not even similar or have the same parts or part number or PCB numbers.

Same JVC Screen, same board even same batch, 20170726 !!!
And you know what ?
I have the same faulty IC 😂😂
Can't believe I've found someone with the exact problem.
It looks like a manufacturing defect in a batch of products.
Can you please share your situation before and after replacing that IC6 8 pin module ?
My screen is not turning on, the system is not responding to any touches & reset button not working too. I checked the Bluetooth and that's also not working (not showing in smartphone).
So it would be helpful if you can share if your problem was same as me and replacing that IC solved it or not.
Look...

An externally hosted image should be here but it was not working when we last tested it.
