great and very patient repair for most repair techs they would have not bothered to go to these lengths.

[@OntarioMiner]

Great Job. Its amazing you went that far to repair that board. Keep up the wonderful videos.

[@Darthy0]

That is some dedication there with the tracing, good job! Don't you worry about interference in those wires? Aren't the original traces designed in specific lengths to match the impedance with such high frequencies, or is it really negligible?

[@MainboardMedic]

You are absolutly right with that and i think this repair will have an effect to the maximum mhz that the RAM can run on the board. But i think for everyday use this will be fine.

[@TrolleyMC]

Wow do more of these, you're like Adrian black except you do modern machines.

nice job finding the open. Just wondering if there is a meggers test (or something) that could help find where the board fault is. I know that troubleshooting isn't and exact science.

Good job mr.Mainboard Medic

Keep those videos coming!✌✌

Next one will be on Sunday!

Very nice video. Helpful 👍

[@Newtype2259]

Awesome fix and very informative :)

You said the missing light on the memory tester was DQ57 and DQS7P, but on the boardview you stated that the faulty line was AJ2, AJ1, and AK3. How did you know that it's the one corresponds to the missing light signal??

[@MainboardMedic]

The pin in the DDR slot was called M_DQS_A_DP7. So you need the corresponding PIN in the DDR slot regarding the tester!

Good job !

[@ted-b]

Great job!

[@theodordan680]

anyone has a schematic for p43t es3g for boardview?
