I would take that out and check the gain of the transistor since it wouldn't actually go open or short and read fairly normal with simple testing with a meter, and replace it as needed.

Thanks Ed for the details.It was awhile back and could not remember all the info .On the Sony VCRs I had several issues when those transistor look alike circuit protectors blown out. At first It took me on the loop troubleshooting it until I read up on it and found out what they were..The Sony SLV-KH3 is will worth it to fix it.
