I red drive problem possibly on the red crt board or from the video jungle IC, like a bad red driver transistor, The resistors on the crt board could be changing value, or the crt socket on the red driver board could have poor solder connections on them. This is not a problem that a end user should attempt, as there is high voltages on the CRT drive boards. Going to need to have the tech monitor the set and test untill problem occours. Should not be a big deal .. Good Luck
