HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. š
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...

Hello,
I have an HP 14-dq0055dx laptop here that came in for boot looping. It was previously taken to another shop and they tried flashing a BIOS firmware to the chip, so I cannot take an original dump. For a second or two, a message will come up on the screen that says:
This loop will go on for as long as you like. I let it run for about 12 hours and came in the following morning and it's still looping.

Hello! I'm trying to resuscitate a Macbook that the local tech gave up on. I have the board view and schematic and have the main board out of the case.
Of the 4 usb-c ports, 3 cycle at 5V - they all go up to about 1.5A, then seem to switch off, back to 5V 0A, up to 1.5A, and off again. The cycle lasts a few seconds - maybe 3s.
The 4th port doesn't cycle and draws ~0.5A at 5V consistently. It seems it's the port linked to U3100 - it's on that side of the board and is the port closest to the battery and the CD3215C00 chips.
I've read that the CD3215s are...Today, 06:46 AM -
Having this very weird issue.
The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.
I swapped with a working screen from an A2141 waiting for parts.
The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.
The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...04-27-2024, 01:37 PM -
Hello, I have a bricked Eluktro laptop, can't seem to find a bios dump. I would like to have the ME cleaned please. The bios download from the Clevo repo has a file with a ".12" extension that is the same file size as the original bios but it is "configured" as opposed to "initialized" according to ME analyzer. I tried it and the laptop still did not boot.

Started with a surface pro 5 repair with battery not fully disconnected and ended with dead touch. Tested with a new touch module and new cable and there still is no touch.
Measured touch power rails 1v8 and 5v, both are present.
From schematics and boardview it seems like everything happens over SPI, the i2c is NC
The MOSI goes directly to the CPU through a 10ohm resistor
MISO also goes to CPU through a 10 ohm resistor but also goes through some buffer/level converter chip (VC125) for SPI sniff im guessing for panel brightness level.

Hello.
I have 29inch LG CRT TV,And Yesterday,Whenever I connect AC power cord to power outlet without switch on, I heard a sound like white noise, And When I switched on this CRT TV, It sometime displayed correctly But usually It won't last more than 20 minute and The screen begin to dark and It finally did not display at all for hours..
Today,I dismantled its plastic case and discharged the biggest capacitor(400wv 470uf) which still holds 250 voltage,and I finally detached PCB from cathode-ray tube.
I measured ESR value of most of caps in PCB with MESR-100 and I found that KME(25v...04-17-2024, 07:11 AM -
Hello everyone,
This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.
My patient is an A2338 Macbook Pro M1 (late 2020).
It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...04-22-2024, 06:45 AM
