Hi all, need some help, I've got a Lenovo V14-IIL that as total of 8GB of RAM (4GB onBoard - 4GB Sloted), out of the blue it stopped posting, After investigating, found out that removing the RAM stick from the slot, the laptop would post and work with no other issues. So tried with a different RAM stick suspecting that the original one somehow died, but to my frustration the issue remained, so again tried a different number of known working RAM sticks with different capacities and speeds but with no avail.... Unplugged Battery, removed CMOS battery,Reset and Updated Bios, also measured voltages...

I have a card that does post at all, the owner said it does go into windows but it gets stuck on the logo with artifacts, I have no idea if he is lying or not... I tried the card on my pc and it does not post at, no beeps, no bios nothing just all fans turning and nothing else. I tried plugging DVI or hdmi but nothing, I tried unplugging the 8 pin plug from the power supply and it's the same thing.
I just want it to post and get into the bios at least.
Forgive me if I am wrong, but I tested the 3 PCIe 12v power pins on the left(550ohm) and the 4th one from the right 3.3v (400ohm),...

I usually tried to find datasheet which contains Maximum ESR value like KME datasheet.
[URL]https://www.westfloridacomponents.com/mm5/graphics/S06/KME250VB10RM10X20LL.pdf[/URL]

As far as I know,Maximum ESR means boundary ESR value for bad capacitor.
But,In many case,there is no ESR value in datasheet like below links.

Hello Friends,

Greetings!

I have taken this active subwoofer from Wharfedale for restoration. This is already in a bad shape as far as the connections goes. It has already been worked by local technicians. The most important part that I am looking forward is the schematic diagram, as there is jumper placed and a track has been cut, as if to bypass the actual connection. I am not sure if this is by design or someone has tried something to achieve.

Another thing is the TDA7294 was badly treated with its legs cut and it had a crack too, so I have replaced it...

[Nash1405]

Have you found the issue? I might also have a very similar issue with A2338, the battery charging sign comes up then the Apple logo comes up for 2-3 sec and shuts back down. can't able to find the issue. I am getting good readings all over the board. A little help would be nice. Thanks!...

I'm investigating the above mentioned Yoga 7. There's something causing it to loop in the power up phase. I can hear a ticking noise before my USB Digital Multi-meter resets.

I'm guessing it's a power mosfet? I'll update if I find anything, but if anybody experience, knowledge or info about this unit, it will be much appreciated. Thanks.

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:

When I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?

Hi.
I got dead one.
3VALW is just pulsing then goes down. i removed the jumper PJ402 and it suddenly stays up but PG pin on that IC is around 0.5v and droping.
There is no obvious shorts. Wierd thing is that on the other side of the PJ402 i have 1.4V from somwhere ...

Injecting 3.3v there draws 300mA and nothing is heating up.

the ic is SY8386BRHC_QFN16 (kinda uncommon here - so i do not have a spare to test it)

any ideas to check before i order a few of these?

I have an induction hotplate UNOLD Elegance Typ no. 58105 (with board CHK-A1.42S) which has a blown resistor.
I have also located the problem in the SOT23-6 component with the marking "9003 KAUCHB"; the pin 5 was disconnected from the IGBT emitter (ground) due to the high temperature and this caused the IGBT to be permanently ON.
I replaced the resistor and resoldered pin 5 of the SOT23-6 component to the IGBT, the hotplate worked for about a month and...

I recently got this laptop on a trade labeled for parts, when first testing it, the motherboard starts on, the power LED stays on while the gpu and cpu fans ramp up in different speeds, then it turns off after half a minute or so.

BIOS and EC were reflashed, did a clean ME already, no change in symptom but then i noticed 3 things while looking through the board:

Hello everyone, I got this notebook, mainboard SKITTL10-6050A273001-MB-A1

Saw the U6100 blown up, so didn't even try to power it up.
Sems that there is not a schematic or boardview of this one, so I attached some pictures (some look distorted; the ic looks like a qfn-16 3x3).
Maybe is the RT2790A; looks to me compatible but their product code is 3B= XX and mine is 38=

TV philips 55'' no backlight (image ok).
I tested the backlight with my led tester from the unplugged connector cable and it lights up. I had voltages at the motherboard connector, but anyway I order a new psu. Same problem, same voltages. Disassembled the TV and checked every strip with my led tester, they all light up, same voltage for every pair of strip (they go two by two).
What am I missing?

And something else I don't understand. I checked and I have 3v Leds, 10 per strips. Why every pair of strip (so 20 Led) take about 32v when powered up with my led tester 🤔

[trepachka]

See attached image. It says "X322" on it. This is a follow-up to my previous posted topic. The issue is upon lid closing, the screen turns off. When lid is opened, the screen remains dark.

This component is positioned right on the edge of the motherboard and has like a cradle made inside the case. I am assuming this component is used as a lid close sensor.

Please, help me identify it. Thank you....

Hi,

I'm learning about motherboard repair and I believe I've traced the issue down for the South Bridge on the particular motherboard I'm working on. My path of concluding that:
- There's no sign of any attempt to power on when pushing the power button.
- No PSON signal is reaching the 24-pin ATX connector.
- The Super IO chip is receiving the PS_SWITCH signal from the power button and is relaying this signal back to the South Bridge.
- The Super IO is not receiving the S_SLPS#_R signal back from the South Bridge
- If I pull the Super IO S_SLPS#_R pin...
