Hello Susan

How are you doing? Hope everything is well. A faulty video board can cause this issue not just the IC. Picture below is the example of the video board.

The tech may replace a blown capacitor but there are several things that can be causing the issue and a blown capacitor is just one. I strongly suggest that you replace the video board to resolve the issue Susan. Hope this helps. Please let me know if there's anything else I can add or help you with. I'll be standing by for your response.

Thank you
