No LCD image after connector replacement – lifted components and damaged resistor (Nintendo Switch Lite HDH-CPU-02)

[Tomylee]

Hi everyone,

Sorry for the person who’s going to read all this !
I'm on a Nintendo Switch Lite, motherboard HDH-CPU-02.

While replacing the left joystick, I had to remove the motherboard to access the connector underneath. When I lifted the LCD connector latch, it broke (the plastic had become brittle over time), so I replaced the entire connector.

During the desoldering of the LCD connector using hot air, three small components located just below the connector (likely 0402 capacitors) came off and remained stuck to the bottom of the...

I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
issue. Set will power up with remote but not power off....

Good afternoon, colleagues. I have a Lenovo ThinkPad S440 with the 1-3-3-1 beep sequence. I've seen videos about removing the memory because it won't connect properly, but that's not it.

My suspicions are either the CPU or the internal memory. Has anyone had a computer with similar problems?
I'm adding information. I've seen...

Hi,

I have an Asus 2021 ROG Strix G17 G713 that is not powering on and not charging. Board number is G533-6050A3250201.
When plugged in, I found that the 3.3v/5v regulator was getting extremely hot, so I removed, next I found a short on the 3.3V rail. Removed the two 3.3v mosfets and found one of them shorted, but still the short on the rail did not clear. Then I injected voltage at that rail, and found out that U60400 the 2.5v rail was also getting hot. Removing it changed the short from 0 ohms to about 5-6 ohms, then I remove a bunch of other suspect components but that did...
