Those Hitachi-made RCA VCRs suffered a failure of the DC-DC converter that drives the VFD.
RCA part number is either 163818/Hitachi# 5262063. There are three electrolytics associated with it that cause repeat failures - they are right there next to the DC-DC converter. When the Converter fails, it eats the IC Protector on the board as well - ICP-N15, IIRC. Get the 163818 kit - they are on eBay occasionally, but definitely ask if the instruction sheet is with it. Makes like simpler. Hope this helps - those VCRs were the best of the era. One belt kit, one DC-DC converter kit, and one Idler tire, and it was fixed. $11.10 total parts cost (I do remember the RCA price on the belt kit was $5.05...). I repaired my first on the USS Forrestal in late 1989 - I called home from Marseille and had my Dad send all three RCA parts - the kits and idler tire - I had a happy QA Officer after that....
