1977 CRT TV wont turn on
Not sure why anyone would want to repair a non hd TV as the picture quality isn't usable with modern content but if you're doing it because you like restoring something vintage here are some ideas. Some CRT sets use a pulse from the back side of the flyback transformer as a starter voltage supply, it needs this short pulse to start the power supply, it's kind of like starting a gas motor, the starter only runs for a short time then the gas motor takes over, this signal needs to be measured with a scope or a high end meter, this was a common issue with a lot of older CRT sets that use this type of power supply. I'd look at the start up supply as without that the regular supply isn't operatable.

Your EEPROM is bad, if you can find one and have soldering skills and the equipment to remove and replace SMD devices that's the cheap way to fix( $15) if not replace the main board, in your case with the sound issue it may make more sense to replace the main as that should correct that isue as well
Picture too dark
mkbowen,
whats the brand name of your TV?
also try this, facing the front of your screen. locate a button indicating " menu" and click it.
once the menu button been activated there would be a display box indicating "AUDIO" "VIDEO" "TUNNING" or in some cases the screen will indicate one by one setting every time you press the "menu" button. If you'll able to find a display indicating "video" higlight the said icon and navigate throught it until you see the control for brightness. you can navigate the icon by pressing +/- channel button and to change the value of selected item you need to press +/- volume button of the screen.
cheers ,

Copy tape to dvd using Q-VHQ 760 & Pinnacle
Check the edge of the tape to see if it's wrinkled. That is the most common problem that shows that line. You may be looking at the head switching pulse too. Since your VCR has no tracking adjustment, it has to be done with special tools, an oscilloscope and a voltmeter. Not an easy task.
