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. 😊
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...04-22-2024, 11:28 AM -
Hi Everyone, hopefully somebody can help me.
I have acquired an ASUS ROG Rapture GT-AXE16000 with a faulty 10GE port. It's locked at 100Mbps. A component on the board went pop but I'm not sure what it is. If anybody has a schematic or knows what the component is I'd be extremely grateful.
I have attached pictures highlighting the thing that went pop.
Any help is appreciated. Nothing else around it looks damaged and a quick check with my multimeter seems to confirm this. I tried taking one of its brothers off and measuring it but, when I tried to grab it with...Today, 02:21 PM -
I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.04-27-2024, 10:55 AM

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.

Hi,
I have a problem with windows activation. The laptop has the original version of windows 8 included by the manufacturer. The laptop worked on the original activated key for several years. Recently I wanted to try to see if I could still upgrade to windows 10 (it was a mistake). Of course, the time to upgrade to windows 10 has long since ended and my key was rejected. I came to terms with this and wanted to reinstall windows 8, I downloaded the system from the windows website, after starting the procedure it showed a window to enter the key, I entered and to my surprise now also...Today, 09:49 AM -
