Question about Mitsubishi CS-40503 TV
You didn't mentioned if it is a horizontal line but i think it is.
It seems that you have a faulty vertical I.C. that scan vertical line.Because you it is defective you've lost the vertical scanning thats why you have only a horizontal line on the screen.
You will confirm it by powering on the unit with your cable signal present.When the sound is present on every channel it is confirm that you have a problem on the vertical section. You must look for a qualified technician to solve the problem....
