the 14DC15 is a 16" portable color hybrid set. Has something like 14 tubes or so. I have a few of these and have never had this type of issue, so I dont have a specific answer. Does the picture tend to slip sideways, or does it go off into tearing lines (like the horizontal hold was adjusted way off)? This set uses individual phase detector diodes. Did you disconnect them from the circuit before testing them? One could be leaky. However, Since you mention it gets better as it warms up, that means its probably a thermal problem within one of the components. Get some electronic freeze spray. give each cap in the horizontal frequency section a shot while its powered up. Problem will be revealed once the set reacts to the cap that was sprayed. It works very well for finding the troublemaker. good luck.
