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'm asking for help identifying the component.. the markings on the smd are totally destroyed and boardview didn't help me much.. I didn't find the schematic ....Thanks!Today, 04:39 AM

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.

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 -
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....Today, 04:11 AM -
Everything works as it should except that it is too dark screen image and the backlight is blue is it normal with bleu backlight ?

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 -

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 -

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 ??Yesterday, 11:48 AM -
Hi, all. I have an Asus Rog Strix GL703G. Yesterday I took it apart to clean out the dust and redo the thermal. Unfortunately, when I attempted to pull the battery, the metal retaining clip (unable to retain itself due to genius engineering) popped off and shorted across the capacitors behind it. Now I have no response from the laptop with or without the battery.
I'm hoping maybe someone can help me read the board and figure out what potentially shorted. I have a soldering station, I can run hot air, I have a multimeter, I just have no idea how to trace or measure the power circuit....03-08-2024, 04:35 PM
