*OK guys, many thanks for the good suggestions in the comments. I've answered some individually but I will just post here as a pinned comment ths tI'll be taking another look at this motherboard on an upcoming video and we can try some of the ideas*
Please fix it for your audience, as we like the deep dives into complicated faults and love nothing better than a happy ending. Keep up the great videos and many thanks for sharing. Keep well and stay safe, Joe
I would try flooding the CPU socket with the Deoxit then replace the CPU and work it up and down in its socket to free up any sticking pins before condemning the board. also ultrasonic cleaning may also help.
The P5VD seems like an uncommon board. It could be worth real money if you get it to run. With an AGP slot and socket 775, I figure this can provide a nice experience running older games and such. I hope you keep digging into this. Maybe get a repair video out of it, yes?
Hello Richard. In the mosfet near the NB you have 10v on the gate and nothing on the source. This Mosfet is responsible for vtt. Or you have a short in this LINE or you have some problem with this Mosfet. Cheers.
Thanks for the info. If that mosfet generated VTT then it would possibly explain why I have no VTT_PGood which in turn generates the VCore Enable signal.
5:25 That's quite communicative of that board, telling you it's faffing about. Sure, it needed an external card to do so, but still quite impressive and that without an Artificial Incompetence core.
I would just inject the high voltage into that enable pin. That way if it works you know the problem isn't that big, and if it blows up the board was dead anyway.
There was a short time between socket 775 and core 2 being released. They actually put out a generation of pentiums first. Many people including myself purchased a socket 775 board thinking "I'll just buy one of the newer chips when they come out". Except the boards never supported it. Intel really shafted a lot of people with that in my opinion. The board has value because of the agp and pcie slot combination - probably around 100 pounds. You should fix it. I would try dousing the socket with IPA and lightly brushing the pins. You don't have to get the gunk out, just get it off the pins. Of course it could be conductive as well. If its conductive, the gunk will have to come out, but it probably won't. That'd be a lost cause.
Just something you could try! (and i might be talking out me bum) if it is a sticky substance then water is a better option for cleaning it off, because you cannot wiping it, then spraying some into cavity of the pins, leave it awhile, and again because you cannot wipe it, then use a little cold/warm air from a hairdryer on the surface to clear the water out and dry the socket holes. just a thought.
Can you give the board a wash then inject the enable voltage / pwr good and see what gets hot? Thanks Richard, great video as usual this one got me intrigued 😂
Yeah I'm looking at cleaning it. Another subscribe rgave me some info about where VTT is generated so I need to check if there is a fault in that area next
@@LearnElectronicsRepair Yeah true they are expensive in that size i got lucky and got an 6L Ultrasonic cleaner (Velleman VTUSC6) for like 70 euro used that one wouldn't fit an ATX board to but i think it would atleast cover the socket with half the board in the ultrasonic cleaner lol
it has the via PT880 ultra chipset - same as the asrock 4core dual sata - thats important because you should be able to have both PCIE and AGPcards installed and be able to select from the bios which card to boot from. The viaPT880pro doesnt allow that as its one or the other = no selection available in the bios. well at least my gigabyte 775 combo board doesnt Retro web says supports 4gb ram - It is a pentium D CPU so yeah thats a bit average but - as a dual boot PCIE/AGP retro mobo - it is worth a bit . Just hit it with a can of contact cleaner first - soak it and see if that gets it clean and going .
Perhaps I am mistaken but it looks to me as though the enable pin is connected to a potential divider (R355 to GND, R350 to 12V) What are the values of those resistors ? I would expect to see more than 0V on the enable pin. Is C638 shorted to GND maybe ?
Another viewer also told me where VTT comes from (mosfet) so I will look further into this fault on another video. I'm also looking for a good way to clean the CPU socket properly as well
R, love your vids. Why don’t you ever use the capacitors next to the chips to get your voltages?. My logic is, that you can’t short and maybe pull another pin to ground and less fiddly?.
It's actually a P5VD1-X, not P5VDI-X. I discovered this by watching your video and looking at the board when you showed it on the screen. If you were saying that all along, don't blame me. My ears can be less than cooperative at times.😉
These days, when people mention eBay, I grimace. I only use eBay as a last resort, but that is because I am in Canada and have to deal with the eBay International Shipping plan when I buy items from the USA.
LMFAO The english language... yeah it is flat its not a ball!! LMFAO it is round too.... it is empty you mean there right ??? LMFAO by the way that is at time stamp 6:30... about the battery LMFAO

Probably that CPU socket has some problem which may not be able to fix. But I can look into the fault further
Found this very interesting , the use of board view which is something I am unfamiliar with seems a very powerful tool.
There are various BoardView viewer like the free Open BoardView and Paul Daniel's Flex Boardview which has a free as well as a paid version.
This video is exactly why I watch your car booty videos, so please continue the hunt for the fault.
I would try flooding the CPU socket with the Deoxit then replace the CPU and work it up and down in its socket to free up any sticking pins before condemning the board. also ultrasonic cleaning may also help.
I was going to ask if you could flood it with IPA, but seeing how you said Deoxit, I am going to say IPA wouldn't be good?
@@twithheldmwithheld8938 Hehe I'm gonna say DeOxit is a US market thing and you can't buy it over here
Anticipation is making me wait

I'm looking for something to clean the CPU socket first. Yeah it is an unusual ASUS motherboard to have 776, AGP and PCIe!

Use your power supply to supply the voltage to pin 11, if it boots you can rule out the socket
I would just inject the high voltage into that enable pin. That way if it works you know the problem isn't that big, and if it blows up the board was dead anyway.
Heya, nice carbootsale I don't mind wen you go deep into details

Stick it in the dishwasher (seriously) and rinse thoroughly. Obvs no battery!!
A socket replacement might be in order? Not an easy procedure but could be worth it. If not for value for an educational purpose.
It's not easy like you say and I don't know if I can even get LGA775 sockets other than taking one form a donor board

Yeah I do want to find a good way to clean the CPU socket. Thanks for the suggestion

i would like to see a repair of this board
i wonder if a ultrasonic cleaner would clean the socket?
Unfortunately Idon't have an ultrasonic cleaner and one large enough to fit an ATX board in is not cheap
@@LearnElectronicsRepair Yeah true they are expensive in that size i got lucky and got an 6L Ultrasonic cleaner (Velleman VTUSC6) for like 70 euro used that one wouldn't fit an ATX board to but i think it would atleast cover the socket with half the board in the ultrasonic cleaner lol

you could try to clean the cpu socket with a soft painbrush, i had some cases where some motherboards don't post because of that
From the amount of corrosion on the case, unless there's an obvious short on vcore, I'd give up.

I thought this, too.

R, love your vids. Why don’t you ever use the capacitors next to the chips to get your voltages?. My logic is, that you can’t short and maybe pull another pin to ground and less fiddly?.
I do often use the capacitors close to chips to measure voltages and I did it in this video explaining why I do this 🤔
@ I’m sorry. I had already pressed send and then seen it later.😪
It's actually a P5VD1-X, not P5VDI-X. I discovered this by watching your video and looking at the board when you showed it on the screen. If you were saying that all along, don't blame me. My ears can be less than cooperative at times.😉
No I wasn't, I thought it was P5VDI=X and then corrected myself to P5VD1-X later in the video

At one point, when is an X86 pc considered retro? Oldest I have is an 1151 ASUS P8P67 DELUXE? 13 years old?
Who can predict? No one predicted back in the 90s that 486 Pentium Overdrive, ISA cards and voodoo cards would become valuable collectables
Keep up the great videos. Tons of useful information. Truly appreciate your knowledge.🔌🧰
@ 7:17 look at the bright side... the fan works !!!! LMFAO
CPU
LMFAO The english language... yeah it is flat its not a ball!! LMFAO it is round too.... it is empty you mean there right ??? LMFAO by the way that is at time stamp 6:30... about the battery LMFAO
For some reason in English we call a discharged battery FLAT. I never thought about that being strange but there you go
