Assistance with identifying replacement caps on ASUS P5VDZ-MX

by crosswinds

Hello,

So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess

Its a ASUS P5VDZ-MX board.

I would really appreciate some assistance on what the best replacement caps would be for these:

Troubleshooting Asus Tuf Gaming A15 FA506QM 33v & 5v rails

by orgamisho

Hello!

I am still learning on laptop repairs and I am currently working on the above mentioned device.
Currently the laptop is dead (no power on). The device takes 2-3 mA when 20v are injected onto the charging plug.
Main power rail is present (20v), but no other power rail is present, including the 3v and 5v. I noticed that when no power is connected the 3v and 5v coils have large (normal) resistence to ground, but when I plug the power, both are being shorted to ground.
I wonder is that an expected behavior or there is an outer protection activated.

A1990 820-01041 5V .4A Troubleshoot

by abajor

I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.

I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.

Does anybody have any insights?

T495s Bios chip location

by Squaryhead

Hi,

I'm trying to locate the Bios chip on my T495s 20QJ to recover the Bios.

The computer shut down during the bios update, now it's just singing. I want to try to reprogram it. I've read the BIOS guide but I'm still missing some information. I hope I'm asking in the right place.

Do you now which one of those chips is the BIOS ? And, are those compatible with the CH341A ?

Thanks a lot !

Toshiba 42HL196 No HDMI?

by jackclements

Hello,
I have replaced the psu on this Toshiba 42HL196 twice. I have no HDMI or tuner. The component and composite inputs work though. I had a spare seine but it just gives me 3 red blinks so it's either a faulty seine or needs programming. It would seem it's the seine board. Ideas?

I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.

Evaluating Mechanical Hard Drives SMART Data in Linux (Ubuntu) Using the Disks Utility.

by abajor

I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.

Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

Sony LED 65X9005A shuts down after few seconds - looking for help

by tec3000

Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...
