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....Today, 03:31 AM -
Evening 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 -

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...Yesterday, 02:12 AM -

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

Hi 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

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...Yesterday, 04:42 PM -
Hello,
im actually trying to save a d1500 delay from yamaha. I found the service manual but schematic is missing and BOM list is a bit unclear as components listed have no reference linked to the pcbs... In my case, one zener diode was broken (114 code on the pcb in attached file) and couldn't be repaired : it was a zener type package. In the BOM list i found 3 reference on this board : 1S555 (can be replaced by 1N4148), RD4.7EB2 (approx 5v rectifier), RD7.5EB3 (approx 7v rectifier)...
Actually the cathode goes to VCC of sram M5M5118P, without this diode missing, i have...04-24-2024, 09:01 AM

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...Yesterday, 01:37 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.Yesterday, 10:55 AM
