On a long shot, I am asking the diversely knowledgeable members for some help. I have an old computer that I have been using on an old tube TV for years with no issues. It is very basic box for watching TV and running an older Ubuntu OS.
Today I hooked it up to a new Samsung flat screen. It is connected through a monitor cable to the TV. It will show the computer booting on and the start of loading. When it gets to the part where the desktop would show, the TV goes black, the resolution size pops up and changes, then it says 'no signal from source, check cable'.
Has anyone ever run across this or have any ideas what would cause something like this?
It was coming up on both 720@70hrz and 680(or 640)@60. Would hop between the 2. I am loading the latest Ubuntu on it now, had it laying around already from a recent laptop load (typing on it now) Jumped it up to 1920, but now blank again.
Some newer TV's you have to change how the picture is drawn as well. Is there a legacy mode in the input selections? IIRC it will say something about "interlaced"
I found the problem looks to be a flaky video card. It would do the same thing with a proper computer monitor attached (they both use the blue monitor cable). When I hooked it back up to the old tv with the s video cable there where no issues. Going to use another old one from a friend and see if it works.
entirely possible your vga cable is crap.
try replacing it.
(if not using vga cable, disregard)
