Hi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...05-12-2024, 10:52 AM -
Hi, I have this laptop, it is completely dead, no charging light when connected to a working charger.
Can anyone help me with some hints for troubleshooting this laptop?
Thanks in advance...05-07-2024, 05:28 AM -
When plugged in (no battery installed), the battery light on the motherboard lights up and then turn off. When powering on, the same and light and the power button also light up in a white color but no output on the display. It stayed like that for a few seconds before shutting down. I also seem to ruined a connector that connects to the WLAN, 2 USB and audio board, the same board also have a melted 2062A IC. I will post pictures in the reply section05-11-2024, 04:40 AM

Hi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off...Yesterday, 09:40 AM -
Lenovo IdeaPad 3 14ADA05 bsod "page fault in nonpaged area" ,sometimes the device works fine all day but the next day it displays this message from time to time.
Replacing the RAM and SSD drive and new Windows installation did not change anything, the error still appears.
I noticed that the laptop turns on by itself after lifting the screen, but I did not find such a function in the BIOS.
Can this be set in windows?
I wonder if it makes sense to program the BIOS.
Has anyone had this happen before and how did you deal with it?Yesterday, 11:34 AM -
Hello, gentlmen!!!
My HP Probook 430 g2 does not detect battery. I tested the battery on another laptop and it is OK.
I believe smth is wrong with my PC ((.
Searching this forum I found some nice suggestions.
So, I tested Battery Connector pins (charger in/battery out) and here are my results:
pin_1 0v (-)
pin_2 3.30v
pin_3 0v
pin_4 3.38v (SCL)
[B]pin_5 2.55v (SDA)!!![/B]
pin_6 2.25 (+)
As far as I understand SDA pin must be ~3.3v???
Are there any other tests I can do before disassembling motherboard?

Hi,
the TV has a black screen. Sound OK, backlight OK.
When I measure T-CON voltages, there is VGL+VGH=0V. After unplug the right side of the screen from the T-con, voltages are OK and half screen works normally.
I tried to search for any kind of short on the right side, but I had no luck. I have a beginner experience in measuring and repairs of the LCD panels..
Thanks to anyone who can guide me in solving the problem.. and be patient with my english 🙂😁Yesterday, 11:04 PM -
Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?...Yesterday, 03:05 AM

I have a MacBook Pro Touchbar A1706 that won't turn on. With the board removed I'm getting 19.62V and an average amp draw of 0.300A. When I first plug in my ampmeter it goes from 5V to 19.62V after a second or 2 and the amp draw starts at about 0.688A and up to about 0.790A and then it gradually goes down to about 0.155A and works it way up to around 0.330A and then it fluctuates in the range of about 0.200A-0.350A. The voltage stays at 19.62V. Can someone with any experience with this issue help me out. I checked all the main power rails and they were present. Anyone know it would be greatly...Yesterday, 12:39 PM

Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...05-05-2024, 06:20 AM -
