FOR PARTS - NOT TURNING ON
Vintage Magnavox Escort 2 Portable B&W Television VHF UHF Handheld Tv
Not sure why it is not working.  I am the original owner but was last used many many years ago.  Believe it was working last time I used it.  Has some minor corrosion from storage from batteries.
Condition:  The exterior is in nice condition.  See detailed photos.  I placed new AA batteries but it does not turn on.  Not sure of the reason.  I do not have the 6V DC adaptor.  Only this main unit is included.
Ty for looking.
