Neotec NT-2700
I have a Neotec NT-2700 full family. It has no picture and a few seconds after you turn it on it blows C117. Does anyone have any idea what I should look for

Hi all,
I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.
I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.
I have tried a few new bios but exactly... -
I have a Lenovo Legion 5 15IMH05H 81y6003yUS that someone asked me to help them with a failing SSD. I installed a new SSD, fresh Win11 installation, updates, etc. Very standard stuff and everything was completed. He said he'll pick it up in a few days so I shut it down and set it aside.
A few days later came and now it won't POST an image, keyboard lights up, fans spin then shuts itself off after about 40 seconds. I've already tried the typical draining capacitance and removed CMOS battery,etc. No display on an external HDMI monitor as well.. No idea what happened. Suspected a BIOS... -
Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for... -
Good evening, gentlemen.
I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.
To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

Hello,
I have an Asus X415EA board that is not charging the battery after some liquid damage. Everything else works, except charging the battery.
So far I measured all the pins on the bq24780s controller with the following result:
1. ACN = 0.0V
2. ACP = 19.02V
3. CMSRC = 18.5V
4. ACDRV = 23.9V
5. ACOK = 5.9V
6. ACDET = 2.57V
7. IADP = 0.17V
8. IDCHG = 0V
9. PMON = ?
10. PROCHOT = 5.05V
11. SDA = 3.3V
12. SCL = 3.3V
13. CMPIN = 0.47V
14. CMPOUT = 6.0V
15. BATPRES = 0.0V
