It sounds like you have a bad connection from either the X sustain or Y sustain boards to the panel itself. After the set warms up, the connection completes and the line goes away. First remember there are DANGEROUS HIGH VOLTAGES IN THE SET AND YOU CAN BE SERIOUSLY HARMED OR KILLED IF YOU TOUCH THE WRONG THING SO BE CAREFUL!. I would get a non conductive probe of plastic or wood and, with the set on and the back off, push on the ribbon cables which connect from the sustain boards to the panel. Once you determine which ribbon cable is the problem, disconnect the power, wait AT LEAST 30 MINUTES FOR THE VOLTAGES TO DRAIN OFF and then carefully resolder the ribbon cable connections at the sustain board in question. If the problem is at the panel end of the cable, I wouldn't recommend you try soldering there as it is very easy to damage the panel connections. You may try simply repositioning the ribbon cable to see if you can find a spot with a better connection. Please be sure to rate this solution. Thanks!
