motorola distorted lines on left screen

hi all, i had posted somewhere else probably about the resistor confusion. this resistor is in the yoke and it looked like it had got hot but the colors were not right and didnt check out right either. it checked at 483 ohms but the sams shows 4.7k so just for the heck of it i put a 4.5k 1 watt in place of this original and these lines were gone and the convergence cleared up. but the resistor was only 1 watt it calls for a4.7k 2 watt so i temporarly put a 6.5 2 watt, it was all i have right now and those problems are all but gone. the thing here is resistors dont go down but rather up in value and this is what didnt make sence to me, 4.7k down to 483 ohms. it turns out the when red gets hot it kind of changes to black so this resistor showed yellow brown black where it should have been yellow violet red.so i guess resistors can go down in value. but the hv issue being low is not cured this yoke resistor didnt help the hv come up any at all, im still at a loss as to why this hv is low and after about an hour and a half the center where the ferrite core is gets really hot and i dont think this was designed to run that hot. the cathode current calls for 105ma per horiz tube so it should be around 210ma, when both together but its 238ma and cannot get it any lower no matter what. sometimes one tube my be better then the other or stronger and with both it will show higher then it should,but no matter what way the eff coil is turned it will go up but no lower then 238ma.so i still looking for a cause of the low hv.
