Hello everyone. I have this board from a colleague, with a short in O2U2 GPIO, it was replaced. But when you turn it on it turns the fans at times as if it wants to display video on the screen, but the loop restarts. If someone has a backup it would be great.

Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
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.
BR,
Michele

I've several amplifiers of different sizes which are faulty. I haven't fixed them because I haven't a clue. This is the smallest culprit. 240v in (UK) and 12v dc to the board. Small neon lights when power button is on. Different dc voltages across all of the capacitors. Where do I go from here?

Hi All,
I have been struggling to repair a HP 8460P laptop. Motherboard does not turn on. I have traced the problem to what seems to be a missing signal KBC_PWR_ON causing Trip2 on IC 5006 (TPS51123) to be activated.

The following components have been replaced but the problem remains.
C5191
C5192
U50006

Listed below are voltages appearing on U5006 when the Motherboard is supplied with power from a bench power supply for the first 15 seconds or so.

Hello guys,

Got my hands on this laptop and started troubleshooting. The only thing I know is it turned off and never came on. No lights and not coming on.

Started doing some checks and found the main rail present everywhere. Something weird though as the gate of the first input mosfet is 3.7V and the output is 20.3V.
Tried to trace the gate and it looks like it's connected to pin 61 on the io. Is the IO supposed to monitor the gate voltage?

5V and 3.3V are missing from the coils. Found by lifting PL6202(on the 5V rail) the clicking fet sound goes...

Hello. Coming to you from the laptop forum. Have a client with the Fortinet 50E that has 320 Mbps as internet input speed but only 20 Mbps output on each and every downstream port (using FAST.COM to benchmark).

Reseller is stating the Fortinet is 'worn out' which does not sound logical at all unless the flash memory is 'worn out'. They, of course, want to sell another + onsite installation fees.

Can anyone share feedback on this unit? What can cause this sluggish behavior. From our knowledge, this device is snooping on the traffic to halt viruses / hack attacks, etc....

Hi guys.
I ordered used LG 34UM88 monitor which should come with 19V 5.76 A adapter from LG.
I payed for monitor but sadly I got scammed it came with 14V 58W Samsung adapter.
Luckly I did not even tried to turn on monitor, but I think they used the 14V adapter.
Is it possible to use 14V adapter and what already damage could happen?

Hello good people of badcaps.

im back with another question

Im trying adjust the current bias accordingly to the manual, but my meter is showing the same value no matter whatever position VR-804a/VR-804b is in.

DC bias is adjusted and is working as intended.

Is my settings on the multimeter wrong ? or should i look for a bad component

note: all transistor are new

Looking for a BIOS for HP 255 G8 (HPL51 LA-L021P).

The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
Before junking the board I would try the new BIOS if it does anything.

Hello,

im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...

Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...

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.

Hello.

I have an Asus X705UV which no longer starts since the last Windows update. I suspect Windows Update of having tried to update the bios and having corrupted it, because currently, I have the charging indicator when I plug in the charger and I have the power indicator when I press the on/off button but nothing more, not even a fan running.
Could someone check this bios and if it is broken, repair it?

pink arrow 3v

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...

Couple of Windows 11 machines have come in this week with the same issue. After you login, the taskbar will not appear (or just be a black bar). No access to Start Menu. Task Manager (use CTL+SHIFT+ESC) works, however the Performance stats seem stuck with CPU on 100% for Task Manager itself. Trying to exit Task Manager result in it hanging as well. No issue if you boot into Safe Mode.

To open in FIT I made:

2. put it in HxD to my file
3. MEAnalyzer shows 1 error after that
4. file opens in FIT

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.

I had this Lenovo Flex 3 1580 worked fine. Suddenly it won't power up. After open it up, I found it can start with lid closed when I plug in the power adapter. (No need to press the power button) If the lid is open, it won't start after plug in the power. After it is powered up, the on-screen keyboard works. But the mouse pad and physical keyboard won't work. The power button won't do anything.

From the symptoms, it looks the keyboard control is not working. The logic of the signal from the lid sensor is reversed. If just one thing is broke, what is it?...
