I just tried to update the firmware on a Sony LCD TV and it apparently killed the TV. It got almost through the process and then just displays the Bravia logo. The amber picture led and red standby led stay on (no flashing). The only way to turn it off is by unplugging. There's no response to the remote. There's also no response to the reset sequence. I was updating because two of the HDMI ports stopped working. Can a failed firmware upgrade corrupt the eeprom with no way to recover? Does the main board have to be replaced? Any help would be appreciated. Thanks

Hello everyone,
I have an Epson PowerLite S18+ projector in the workshop showing signs of a firmware fault. I’ve checked all voltage lines and signal paths, and everything seems within normal range.
Here’s the issue: when the power cable is connected, the power LED immediately turns blue even though the projector doesn’t start. When powered on, the fans run but the lamp never ignites. After a few minutes, both the temperature and lamp indicators turn red.
I’m attaching the backup I read from the IC in case it’s useful for analysis or comparison.
If anyone...10-16-2025, 07:48 PM -
The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hello everyone, I described the symptoms and measurements here
It seems I tried everything, my last idea is that the eeprom or firmware (or both) may be corrupt.
I'm not able to find eeprom and firmware dumps in open sources.
Hoping someone here has access to closed forums or manufacturer's service center resources and can help get those dumps?

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 -
I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...
