Heater resistor value change may be required. Solution: When replacing the CRT the following changes may be necessary. 1. When replacing the CRT the original may have used a braided wire across the CRT to ground the CRT and CRT Board. The replacement CRT uses a grounding wire that connects to a ground lug. This grounding lug wire should be packed in the replacement CRT box. See picture below. See note on last page Ground wire P/N 1-900-235-84 Fig 1 Reference: CRT Group PJA PRINTED IN USA TV Products Service Bulletin No. 513R1 2. Heater resistor value change. When the CRT is replaced it is required to check the heater resistor value. This resistor value will change depending on how many newer CRTs are used. It should be checked even if you are only changing one CRT because one might have been replaced prior to your present repair. Failure to do so may cause the CRT life span to be shortened. In order to determine if the CRT heater resistor is the older value or not, check the color of the CRT plastic pin base stem. (See Fig 1) Black stem indicates an older CRT and the value of the heater resistor was not changed. White stem indicates a newer CRT and the value of the heater resistor may require a different value. 3. Procedure for replacing the heater resistor. 1. After replacing the defective CRT, check the color of the CRT plastic pin base stem of all three CRTs. (See Fig 1) 2. The value of the heater resistor, on the E or G Board depending on the model, will be determined by how many of the CRTs hav
