envision h712a (maybe radio shack) no screen

comes on for a second then shuts off, can't get the menu function to work, measuring 4.75 V at what I think is a 5 V supply line, any schematics around ?

Just so you know, the Brand of the monitor/TV you have is actually made by AOC. Radioshack has sold them for a while.

If this was about 10 years ago I would say go into radio shack and have them thumb through the RSU catalogs... but its not.

As far as anything goes, your best bet is a service manual. and honestly, from there... it may be as simple as replacing some capacitors... or may be as complex as troubleshooting things down to an IC... do some googling for the AOC model number and "service manual" (with quotes will use the EXACT phrase within google) like:

AOC h712a "service manual"

I found this hit that may be worth some investigation.

Good luck!
