Is the firmware correct? Have you ever tried the old software by mstar in rt809 bundle software? There are several videos how to load again boot files and then start "upgrading"Leave a comment:

This thing is pretty expensive. More than an average notebook.
Anyway. I got this job over facebook market place. Customer said he bought it used and it was working fine, then he decided to upgrade firmware and somewhere along the way the battery died or whatever we don't know, it got bricked. That's his story and he's sticking with it.
If we connect power supply to it, we are getting 21 milliamps and nothing is happening. Pressing buttons does nothing....-

by zklgfsHi,
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...-

by void_ptrHi, folks. Thanks for all the work on this site. I am looking for help with a TV. I have a secondhand 15" LCD TV that won't turn on. The board is listed as CV3553M_B24_10 and the panel is a MG1561B01-1. I just want to use it as a portable gamer display and maybe a media player. The branding is "Emerson ETC-1500N" but I know it is a generic Chinese TV. Searching on the internet for compatible files turns up zilch and the ai bots aren't much help. Can someone please help me locate the fw for this TV?
