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

Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.
So I got this Dell Inspiron to play with.
No charger, so I connected to my bench PSU.
The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).
------What it did (and didn't do)------
1) I turned it on and it powered on. Powered down in 2 seconds by itself.
2) Removed RAM, changed slot. Same...04-04-2024, 12:39 PM -

by nobbnobb1I am trying to get a set of Creative T40 computer speakers to work again of which I believe the problem is bad caps (470uF @ 35V). So I get a generic set off Aliexpress. The brands are meaningless, but if anyone cares it's a "Chongx"
When they arrive, to my surprise it's much smaller than the originals. These are 8mm x 15mm whereas the OE is 10mm x 20mm. Unfortunately my meter does not test capacitance but I'm guessing there's no way this meets spec at 80% the size.
Thoughts? Is it still worthwhile or safe to try and install these to see if...-

by valente222Hello 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.

by Drake328Hello,
I recently got a PS5 with an EMD-032 board and someone before me “tried” to change the HDMI port. Unfortunately, a few SMD components are now missing, see image. the top one should be a 100nF cap. but what is the lower (0Ohm resistance?)

by tec3000Hi 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!...03-20-2024, 07:29 AM -

by timonix20hello everyone I am looking for a solution for my tv, I think corruption of the eemc,
the TV starts, LG logo, then nothing (rear backlight)
no reaction to rear command or infrared
the usb procedure that I tried on the LG site is a procedure with the screen and the remote control so I can't.

by trepachkaHello,
I have this Thinkpad T15p Gen 3 laptop. It starts normally with keyboard lighting up, I can hear the fan starts spinning, amps quickly reach about 1.7A without the battery, CPU gets hot. However, it is not posting.
I suspect the BIOS is corrupted. I am providing 2 BIOS files as I see 2 BIOS 256Mb chips. I am also providing a photo of the chips' location on the motherboard.
Model: Thinkpad T15p Gen 3
