Question about RCA 14F512T 14" TV
The blue video drive is out. You would have to trace the circuit back from "KB" on the CRT board to the video processor chip and see where it differs from "KG" and "KR". Check for bad solder connections, especially at KB and Q509 (about 0.5 inch away from KB). If you don't find any, then you'll need to do electrical testing. I assume you know how to use an oscilloscope and avoid getting zapped while working inside the TV...
