by RGSoundGood morning I have a problem with my [B]Samsung UE49MU6120KXZT (Version 01)[/B] TV with Motherboard[B] BN94-12644A[/B].
After disconnection from 220V the TV remains switched off with status led off. I need information on how to proceed with reprogramming the flash memory and the BIN file to reprogram it.
I have purchased this programmer on Ebay: [B]CH341A EEPROM PROGRAMMER FLASH BIOS 24 25 SERIES + CLIP TEST[/B]. I include photos of the motherboard. I am not very experienced but I would like to learn so the more detailed the information, the better it will be for me...05-17-2024, 04:55 AM -
by ScarfycakeHi all,
I sent my [B]ProArt Studiobook 16 OLED (H7600, 12th Gen Intel) [/B]to the local repair guys to have a very simple DC in port replaced. I sourced the part myself on accessoires-asus (french company) after struggling to find the right part in the UK. It looked completely the same to the installed part from what I can tell. Originally the only issue with the laptop was a bad / loose DC connection, and so the computer and battery acted completely normal aside from a very poor connection that would fail at certain angles. After the repair was completed I brought it home and used...5 PhotosToday, 08:16 AM -

by matheus30When I took it out it broke, and I want to get the same one or one of good quality.
Where can I buy it? On AliExpress they do not indicate the maximum amperages, and on Mouser or TME.EU it is impossible to search without having the exact reference.
Inductor needed:
It is the PP5V_G3S Coil of an A2159, 820-01598 (L7670)
On the front it says: 1R5
and in the schematic:
1.5UH - 20% - 12.5A - 0.017Ohm
PIMB062D-SM
152S00268
Can someone tell me where to buy it?
Thank you so much.Yesterday, 11:44 AM -

SN: PF1Y5BBJ
Board: GX490 NM-C661 Rev: 1.0
I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.

by kingblade20Hi,
My M3401QA does not power on properly: no display (all black) and with white LED charging port blinking slowly (once every ~3 seconds).
Checked several points across the board and supplies are up and running but I need to double check when I get schematic.
Result is still the same even with DC jack inserted and battery connector removed.
Tried flashing the latest BIOS as of this date to no avail which I suspect has something to do with DMI but tools could not run properly on my machine and couldn't find manual copy of DMI through hex editor and not sure...-

by ianbakHi,
I have an HP 255 G8 that runs for as long as its battery holds charge but won't accept AC power.
I have partially diagnosed the problem and the issue seems to be that there is no ACDRV output from the BQ24735 to turn on the two input MOSFETs. The 24735 has a VCC of 19.57 V, the ACDET input is at 2.93 V and the REGN 6V LDO is outputting 5.98 V, so everything looks good - but ACDRV is stuck at 28 mV.
I've already replaced the 24735 and both input MOSFETs and nothing has changed.
I'd appreciate some suiggestions as to what to try next.Yesterday, 08:45 AM -
