Re: Blast from the past: Asus A8N32-SLI (Socket 939 AMD glory days)

Sorry to bring bad news, but that board uses a nForce chipset which has the dreaded "Bumpgate" failure baked-in. That is the reason why your PCI-E ports don't work.

Removing the chipset heatsinks,...

Re: X550CC Rev 2.0 Convert UMA

This model starts on CPU integrated graphics first, you do not need to convert to UMA if dedicated GPU is bad, it is able to simply ignore it.

What problem are you experiencing with your laptop?...

Re: curious case of an overheating intel lan chip

^^ It's really a lot less tricky than you make it to be. For a BGA this size, a simple hot air rework station, soldering iron and braid should suffice for replacement.

Re: Lesia phone "supported API 3" Bricked

I have always flashed these devices under Windows, the Chinese companies only supply Windows software. MTK chipsets have the USB download mode stack in the bootloader, so it's impossible to...

Re: Lesia phone "supported API 3" Bricked

From the info I found on the internet it looks like this uses a Mediatek MT6580 chipset. You will need SP Flash Tool for MT6580, MTK USB VCOM drivers and appropriate firmware. To flash the phone, you...

Re: LG 42PQ6000 - "overlying" blue tint

The CPU is divided into several blocks. Not all of them are required/active at the same time, so the CPU's power consumption and heat output varies depending on what it's asked to do.

It is...

Re: Bakon 950D "Extra Crispy" mod (19->24 Volt)

91K goes in parallel with R11 (OVP) not R24 (feedback). 15K is in parallel with R24 (originally 4.42k) which gives 3.414kOhms as a final value for R24.

But yes, I agree, 3k3 is too low. 3k3 for...

At work we retired a 1TB Western Digital HDD in the data recovery machine that had over 41.000 hours. Still zero bad sectors but it was used to store backups so we decided to take it offline.

Re: Bakon 950D "Extra Crispy" mod (19->24 Volt)

Yes exactly. R24 (bottom feedback resistor for TL431) is the one that needs to have 15k in parallel added, take another good look at the pictures, stj. :D

I did not check the Russian schematic. I...

Re: Bakon 950D "Extra Crispy" mod (19->24 Volt)

It should work without messing with the current shunt, mine does no problem. Try 20k for R11. 27k (original) paralelled with 91k gives 20.822k, so 22k is a bit high and could very well be your issue....

Re: Aliexpress oscilloscope....good idea/bad idea ?

If you only do SMPS work anything past 20MHz will do great. If you want to measure clock generators on mainboards or bus clocks, you will need higher frequency capability.

You would be better off hunting for some used Tektronix or HP/Agilent scopes in that price range. There are some for sale locally as well, i've seen a couple 4-channel ones for that price. If you...

Re: Toshiba L50-A no 640x480 resolution

Quickest fix would be to replace EEPROM chip on the display with the one from the cracked screen.

Re: MBP 820-2879B Board view vs actual board

Your approach is correct, you need to figure out why you aren't getting PPBUS_G3H starting from the adapter on down. See if PP3V42 is there first.
