As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?
And if you wouldn't mind to keep this thread \"clean\" let's try to keep the the chitchat (i.e. even the welcome to the board replies) to a minimum or this thread may get to 100 pages fast
So I'll start things off :
My name is petabyte and I'm a forum junkie. :oops:
I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

Samsung Monitor S19F350 19" Main Board LS19F350 SF350 (P/N: 2017219005D121)
Hi! The backlight doesn't work, but the board itself works. I checked every diode on it and they all light up. Shim is definitely working as I changed it for a new one.
I found the datasheet for a similar chip OB3351.
VCC (1 leg)
14v comes
VDD (leg 14)
It has 3.5v.
Smd capacitance checked C913 it has a thousand nanofarads.
vLos-1.2% looks like it is working.

Hi friends, I have a problem with this laptop. It gives me a processor error, but when I measure the processor, it has power, heats up, etc.
But at first I thought maybe it was the BIOS. I tried reprogramming it, but nothing.
After that, I measured the graphics card and realized that the graphics card has no power.
So I lifted the power coils and checked that there is power, but when it reaches the GPU, they go to ground.
With a thermal camera, I realized that it apparently has a short in a VRAM. After removing the short, it goes to the GPU.
So my question... -
Hi, i'm having problem with Acer pt314-51s - laptop stopped to work on the battery, i've got original replacement battery and it has the same issue. While battery connected, it does not show voltage on the connector on neither battery. In the system it says charging (One battery 100%, 2nd about 5%),
Laptop does work on the charger.
While charger connected:
PQB11 - Both sides 19v
PQB12 - Both sides 19v
PQB1 - LEG 5 - 19V, 1-4 0.15V
PQB2 LEG 5 - 0.15V, 1-3 GND, GATE (LG_CHGR 0.012V)
LX_CHGR - 0.15V
BST_CHGR_R - 5V
