Toshiba 49L420U does not turn on
The 5 and 3.3 voltage is standby and that would be good if you get a standby light, you won't see the 16 volt unless the power supply is at full power or out of sleep mode. Look at the legend on the power board connector going to the main for something like PWR_ON, it may be marked different, but will have something about power on, you need to see just over 3 volts there when you push the power button, if 3 volts is there replace the power supply, if you don't see that go to the connector coming from the inferred board on the main board, measure the voltage at the pins, one will be 5 volts and one of the others need to change voltage when you push the power button on the remote, measure these one at a time, if none chance replace that board, if you see a change in voltage on one of the pins replace the main board.

Trouble with Toshiba flat screen
Over time with heating and cooling of the power board the fuse holder loses tension and won't make proper contact with the fuse, remove the fuse and bend the contacts together and see if it works, if it still gives trouble replace the power supply or solder the fuse to the holder if you have a soldering iron and can do the repairs.

I have a Toshiba dvr620 and can't remember which buttons to push to activate the sound.
What TV or monitor is your DVR620 connected to? There is an Audio button on the original DVR620 remote (not a universal remote), it's just above the TOP menu (displays the Title List for the current video). This lets you access a DVD audio menu or change a VHS playback between Hi-Fi or mono audio out. All other volume changes will be controlled by the controls for your TV or sound system. (This will depend on which video/audio out you have connected. Optical and some RCA audio output choices will be connected to an amplifier or home theater speaker system. If you are using HDMI or component/composite cables to a TV, then the TV speakers are probably active.)
The manual for the Toshiba DVR620 is available at Crutchfield on the product page: https://www.crutchfield.com/S-Qjp9jnoviHC/p_052DVR620/Toshiba-DVR620.html
. Look under the What's in the box header on the right side of the page. The current link to the manual is https://pdf.crutchfieldonline.com/ImageBank/v20101107082900/Manuals/052/052DVR620.PDF
I hope this helps.
(If you have the DVD recorder connected to a monitor that doesn't have speakers, connect one of the audio out options to a sound bar or other audio equipment.)
