Hi I have same problem with my AV-48WP30....before it was the green line and I had repair man replace the STK392110 part...but now the red line is wavy and not aligning. I have been told that there are two diffent parts for the two different colors???? And that both should have been replaced at the same time. Is this right?? What other part do I need to replace to get a picture on my TV again?? Any one out there have suggestions???? Thanks Carmen
