Hi i need bios for it, becouse is no video on lcd and capslock flashing lights. thanks
-
As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
Hia, I'm pretty sure am having an issue with an LED driver on my grow lights.

Hello everyone, so the problem is the tv would seem to power up when i hit the power button as i would hear a relay click, sometimes it may give me a good picture for about 5 secs or so, sometimes i get a black screen, then shortly after it will click back off and i get power and opc lights flashing together twice followed by one flash of the opc light then it repeats.
Please correct me if i'm wrong but i understand the flash sequence indicates a possible power supply problem, can anyone say if this is accurate information? So going on that i went ahead and tried a factory reset, checked... -
I have the above TV. Black screen. Power blinks 2 times. OPC blinks once. Plug in with channeldown/volup. Powers up with solid green power but no light. I removed, cleaned and tightened the screwed on the inverters. I tested plug coming from the power supply to the inverter board when unplugged. INV12V shows 7.4 V DC. INV60V shows 0.1 or something like that. After plugging in the cable I don't get meaningful voltage from either one. (I measured after booting the TV with channeldown/volup.)
Is this a bad power supply? Or am I measuring something wrong.

So Ive aquired a rx6800xt which i believe was dropped at some point by previous owner, it artifacts (pixels shifting) in desktop and in 3dmark i get disco lights (multicoloured flashes. Ive ruled out the ram because I can mine eth (very ram dependent) or heavier algo's full power without issue or stale shares/errors. Ive tested resitances and they seem to be good on all points (12v, mem, pcie lanes etc). Under microscope theres no missing components. A repair guy said to me its likely dying core which got me thinking.
Since it was dropped is it possible some balls cracked under the...
