I have a Hitachi 31DX10B that has no color and it appears as though X501 (3.58Mhz crystal) may be the culprit. The Hitachi part # is 2791505 and it is NLA. Does anyone have one on their shelf? If not, do you think I can get away with using something else? I have been down this road before with other sets in the past and had to use the OEM crystal to restore my chroma. The set is at the customer's home and I did not have a scope with me during the service call. I am not going back unarmed.
