Re: le37b550a5w turns on 10 secs then off and repeats
Likely corrupt/bad main board due to watchdog triggering. People on here have not had much success on these, except by replacing the main board. Access service menu and try reset (from standby Info Menu Mute Power.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

More likely it was just a bad board to begin with (corrupt firmware is possible), if you got good picture it would not be incorrect.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I have a MacBook Pro Mid 2012 with 820-3330-B board.
The laptop shows a green light on the charger, turns on and the fans spin for about five seconds. Then it turns off and this repeats over and over.
Before it turns off, the SuperDrive (DVD/CD drive) makes a noise like it does when it first turns on from cold (on a working machine).
I am stumped, can anyone help? -
Hello everyone,
I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.
Well, my decice specs are the following:

CPU: Intel Core i5-11400H
GPU: NVIDIA GeForce GTX 1650
Motherboard: GH51G LA-L181P Rev:1c
The symptom:
When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...05-26-2025, 10:49 AM -
MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.
I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue.... -
Hi,
I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...08-11-2025, 02:14 PM
