Hellow guys, i recently have a Asus 4070 Ti, and a EVGA 3090 Ftw3 both with Dr-Mos Problems.

My question is this : I am having real difficult time desolderig and solder again a new Dr-Mos. Is taking for ever to do the job, especially when you have to disolder the dr-mos and with the IC you are taking along caps, resistances and ... welcome to hell!

I am using a pre-heater board with a temp of 120C and a Quick 861DW 480 Temp air 80. And with all these its like a nightmare take out these IC's and apply fresh solder and install a new one.

So i am asking you...

good night! I have this TV, with quite poor build quality. It has a tcon integrated into the panel, a single flex from the tcon to the panel, and the 2 panel controller boards joined by glued flexes. There is no way to separate them.

The symptom is that the image is not visible, but the backlight works. How to know if the problem is in the main or in the tcon-panel? I can't override zones.

Hello everyone, I have this Asus model X556UA that when plugged in I get the white light but nothing happens when pressing the power button. I've been looking into it following the power sequence and found out that the power button is sending the signal to the EC (PWR_SW#) but the EC is not sending the PM_PWRBTN# to the PCH (it always stays at 3.3V). I'm stuck here and don't know what else can I do, maybe I can get some help. I've seen that this could mean that the PCH is dead but I don't know how I can confirm this. Also this may not be important but when plugged in, the PCH/CPU (they go together...

hello everyone.
I need binary for Epson L3150, this printer is something special today. It happens that when you connect USB to the PC, it does not recognize drivers nor does the software even find it to load the emergency firmware again. The device only turns on and the power button LED remains constantly on. The head normally comes to its ready position but does not react to buttons or scan. I point out that I have also tried installing a new head, scanner or new button panel... but it is still in a vegetative state. Has this ever happened to anyone?...

Hi everyone, the tv was in a continuous reboot cycle. To get the best screen image i can I taped the VGH and VSS pins on the left side buffer board joining ribbon.

I am left with a good image apart from the black horizontal lines that I cannot get rid of.

I cannot find anything on the buffer boards that has shorted.

Do you think there is anything i can do to eliminate the lines, or are they caused by an internal panel short and the image cannot be impoved.

Many thanks for your assistance

Hi. In the process of troubleshooting an MSI GE78HX laptop that does turn on (on its own), turns on the backlight on and off in infinite cycle, turns on RGB keyboard backlight and light bar. The CPU gets hot, and its fan spins.

The laptop charges the battery, turns on charging lights, which leads me to think the EC (ITE5571E) is ok. Laptop has no shorts, apparently. Memory is ok, tried it in another machine. Tried 5 different sticks in this machine as well, does the same. Memory connector seems ok, no pins bent.

First, I am going to try to backup and reflash its BIOS,...

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 🙂😁

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...

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?

Customer computer came in, did a DFU revive, no luck, gives error, swapped out battery with two known working batteries still no luck. Board gets 20Volts, raises up to 1Amp then restarts, track pad clicks etc. Tried DFU restore, informed the customer that data recovery is most likely not possible since it didn't give us a revive and DFU restore was the next method to save the board, however it looks like not even DFU Restore is working as well. What could be causing this? I am assuming this is the infamous A2141 flaw that has the flawed Data lines that fail? Any suggestions would be great...

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...
