820-3662 Video Issue

[WiFiComputers]

One of my client Macbook 820-3662 Randomly shuts down or some times no video at all. No liquid damage at all. Motherboard looks clean, Any Suggestions please

is their any solder joint issue on this model as well, like u8900 on other macbook

The usual 3662/3787/00163 problem. Not really a common solution to this. Sounds like replacing the CPU VCore power supply with new chips has had decent results, so there's a chance!

Fix is on the way. Need to test if FDMF6708N will replace the 6808 ones. NEW FDMF6808 are nowhere to be found and all are sanded down garbage.

If this works let us know Duke!!! I've had a few people call about the shutdown issue, and I want to fix it as more and more of them fail if there is a way.

If you are US based order some 6708N from Mouser. I have to wait for China.....

I ordered from 4 sellers and all was garbage. I have 6708 on the way and I have no idea what the difference is as there is no datasheet for the 6808 as it is an Apple only part number.

I'm about to order 6708 and test. Should come in 3-4 days.
