my play / record function on my RCA TV/VCR model# t09082 stopped working suddenly when I moved my tv from one room to another. I transported it in a slanted position. It has been playing and recording beautifully. Now it will play with great distortion for only a few seconds. Is there a way I can identify and clean the head(s) or know specifically a better way to troubleshoot and self repair vs taking it to a technician for a repair cost anywhere from $35 to $150?
