I have an old color TV, MGA (Mitsubi**** Electric) model # CS-1346R, I
think it is from about 1990. It has worked perfectly for me for all
these years. Now I have it hooked up to aa DVD player with all sorts of
adapter cords and this has been working for me for a couple of years. A
few days ago, after watching some DVDs, something is amiss. Now I can
turn the TV on/off and adjust the volume using either the controls on
the TV or the remote. But I cannot switch channels via the remote or
the controls on the TV. There is a button on the TV to switch between
TV/Cable/HRC, this is usually the culprit in matters like this, it
corresponds to the display button the remote. When I press the display
button, it says EXT on the screen, this is not mentioned anywhere in the
manual. I haven’t a clue what it means. The one channel it’s on (3 for
using the DVD player) comes in great. There seems to be some sort of
programming malfunction.
Any ideas about how I can fix this?
Thank you,
Jules
