I upgraded the firmware with one of the versions of 1.9. The speakers are now dead. The headphone still works. I opened the tablet up and measured the voltages leading to both speakers while it's playing music. When headphone was plugged in, voltage was zero. When headphone was unplugged, it showed some voltages. I can't tell if the voltages to the speakers are correct. My knowledge with electronics is very limited. What could have killed both speakers? I'm suspecting that maybe heat generated during the upgrade killed some components?Not sure what to do now.The tablet is quite warm/hot at the bottom even with normal use. Should have used a laptop cooler...
