Hi 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?...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Solder joints on heat sinks matter?
Hi,
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.
Thanks

Metrix scopes
just got a late 90's one.
just a warning to others.
unless you intend a complete teardown and rebuild - dont buy one.
because to remove the main board that fills the case and goes under the tube thats what you need to do!!
even the fuse is under the tube!
oh - and it had a RIFA in it....

Dead LA-H323P (no light) - HP 15-DW
Need help here...
I'm new on the forum and I'm not professional in electronics so i ask sorry in advance for eventual errors...
As title says, i have a LA-H323P dead.
Now, little background.
The computer was working fine, just seems that the cable of screen was dying because it had the classic color problem, sometimes green, sometimes violet, sometimes perfect, but anyway working.
When i opened it the battery was so fat that was seriously near to explode.
So i removed the battery... and turned on the notebook... that was, again, working perfectly fine....11 Photos

PS4 pro BLOD broken component
Hi, I have bought a non working PS4 pro. The seller said that the PS4 was working, he changed thermal paste and now BLOD for 5-10sec.
While inspecting the board (NVA-001) I found this component that was damaged (see photos).
I was wondering if someone knows what component it is…
Thanks

Converting HP EliteBook 840 G7 non-touch to touch if possible
I am trying to convert a HP EliteBook 840 G7 notebook from a non-touch to a touchscreen. I purchased a complete touch LCD assembly with a screen/back cover/bezel/video cable and swapped it out with the original non-touch LCD assembly.
The screen works but the touch does not. I know the new LCD assembly is completely functional because we tried it on a similar touchscreen EliteBook 840 G7 and the touch works there.
I contacted the seller and he said screen conversion like this will not work due some difference in the motherboard for non-touch and touch capable EliteBook 840 G7.

Need help creating an empy Intel ME for HP EliteBook 1030 G4
Hi!
I've got a few identical HP EliteBook 1030 G4 laptops. Most of them I succeeded flashing, but a few went wrong. Therefore they're BIOS is now corrupted. Here is a dump of a correct/working bios (no password, fully working, exact same ram, display, LTE, WIFI etc etc).
I tried cleaning the ME region myself (see attached file), but i think that's wrong, because it doesnt start with the correct amount of zero bytes...
Of course, just flashing those binaries on a different laptop will result in HP Endpoint Security controller problem and resetting the bios after...

A2141 Screen replacement. Boots screen freezes on Apple Logo 1/3 status bar unless connected to second monitor.
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...

How do you trim a BIOS file?
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.

TRIAC circuit
Anyone is familiar with a TRIAC circuit?
I came across this schematic, and I built it, but I can't seem to figure it out why I'm getting a low AC voltage output at the TRIAC terminals.
With 230V AC hot side at the TRIAC MT2, I measured 60V AC between MT1 and neutral side when the comparator output LED indicator is on, and 20V AC when it is off.
Same result if 230V AC hot side is at MT1, and I measured between MT2 and neutral side.
My heating element doesn't work with 60V AC. It's not even getting hot and the thermocouple amplifier output is a...1 Photo

ASUS ROG MAXIMUS Z690 HERO - Component identification
Hi Folks
I got an ASUS ROG MAXIMUS Z690 HERO mainboard with missing components on the backside near the HDMI output.
Unfortunately there is no documentation available nowhere for that board, I did also not find any similar ASUS board design. Even Russians nor Chines have anything available here (nor BV, nor schematics), so only way to discover the parts is from a real physical board.
On the picture left the area where the missing componets are is shown.
On the right picture the detaileed view is shown.
It seems that a double mosfet is missing, probably...Last edited by DynaxSC; 04-26-2024, 04:49 PM.

Gigabyte R9 390X
Good Day to All,
I hope there is someone that can assist me with my GPU. Is does not startup at. Zero fan spin. GPU not heating up at all. I have checked all fuses and voltages that I can find. The one problem (if it is even a problem) is a reading that I am getting off a mosfet. Between Pin 1 of L1014 & Pin 4 of Q4026 ( PS_VDDC_UG5_R) gives me a reading of around 645-650 ohms. Between Pin 1 of L1012, 1013, 1015 and corresponding Pin 4 on Q4020, 4023, 4029 all give a reading of 7.73kohms...

INSPIRON 5570 bios maddeningly slow
hi guys, i have dell inspiron 5570 with a maddeningly slow bios.
specs are: service tag 6MSTDP2 CAL50/DAL10 LA-F115P REV: 1.0(A00) CORE I5 with radeon graphics
When I turn on the computer it takes approximately 5 to 10 minutes to boot Windows, sometimes up to 15 minutes.
That slowness is visible even within the bios menu. It seems as if the clock frequency has been reduced drastically

T495s Bios chip location
Hi,
I'm trying to locate the Bios chip on my T495s 20QJ to recover the Bios.
The computer shut down during the bios update, now it's just singing. I want to try to reprogram it. I've read the BIOS guide but I'm still missing some information. I hope I'm asking in the right place.
Do you now which one of those chips is the BIOS ? And, are those compatible with the CH341A ?
