Bad caps don't always show visible signs of failure. You need an ESR meter to test them in-circuit. If you had an oscilloscope you could connect to the RF output test point of the head amp and see right away if it is working or not. I suspect something else down line in the video processing or muting circuits.
Far as a reliable VCR most are going to be old and loaded with electrolytic caps and rubber parts. Find a newer model that works. A "euro" VCR? Only one I knew about was the Grundig Video 2000, a failed format. Most all brands sold worldwide were Made in Japan (preferred) until they became cheap commodity items made in China.
