my g513rc was doing a windows update and it had a bios update in it, the system rebooted, was doing something rebooted again, and hasnt functioned properly since..
ive researched reparing my bios, i have a ch341a black with 1.8v adapter, ive made 4 seperate dumps at different times for redundancy...
i have a feeling my bios is corrupted and preventing my system from booting..
does anyone have a g513rc bios dump i can test ???
or is anyone willing to help me out in another section with fixing my dumps ??
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

by jm1234Hi,
solder joints on heat sinks - how much do they matter? Could poor joints on heat sink cause issues if they are not properly joining to hot ground?
I'm looking at power source module of Panasonic plasma TV and I see many of these having visually poor quality, but could they matter? In general I would guess no, but I saw a video where someone was stressing out the importance of tightening the screws when fastening the power source board specifically for the ground to be connected properly.

by EazyBoneLooking to up my game a little bit, but these programmers seem a bit daunting.
Trying to get a device for EMMC repair, and it's very difficult to lookup all the words to find if I'm on the right track lol.
Trying to reprogram EMMC on Sony/Hisense mainly but would like to hit a few other brands.
My question is would either of these work? And is there a specific card reader I need for TV emmc? There is like 10-40 additional pieces that I can get but not sure what I actually need for my application only.
I may do eeprom as well. Can someone point...04-21-2024, 08:18 AM -
by fuusEvening all,
Long time no post!
I have a UE49NU7100K here with the classic melted diffuser and damaged backlight from getting too hot. Locally there is a UE49MU6470 available which I could pick up to replace the melted diffuser. Would this work or am I missing something? They look like the same style of backlight.
If this sounds good, where is the best place to buy a new backlight? Will I regret buying from Aliexpress?
Thanks in advance for any help04-04-2024, 03:34 PM -
by ongobongoHi guys,
I have another problematic laptop here, a Dell Latitude 7420 2-in-1 with touch display.
Motherboard is Compal LA-K371P Rev.3.0.
The laptop has a strange display problem, see attachment for more details. This problem is not windows related, as soon as you start the display has those lines even in the Bios. If i attach an external monitor, the lines do not appear there.
I was able to get my hands on a second display, but the problem persists, so it seems to be something different.
any ideas?...Today, 07:33 AM -
by mitchwLooking for a BIOS for HP 255 G8 (HPL51 LA-L021P).
The main problem is that the laptop will crash while booting to OS. Will crash even on booting from USB, like a Ubuntu or to a Windows 11 installer.
Before junking the board I would try the new BIOS if it does anything.
Thank you!...-

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.

by michdundeeHi 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

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...Yesterday, 01:37 PM -
