Hey all, My 27-inch RCA Flat Screen has begun exhibiting problems. Occasionally, when on, the television will make an electrical "pop" sound while simultaneously visually popping a type of "electrical interference line" on the screen. This issue lasts all of about a half second, but its frequency is beginning to increase. I've tried searching for this issue on Google but to no avail. I suspect it may have something to do with the power supply or the tube itself. Does anyone here have a clear answer to this mysterious problem? FYI: Here is my television in case it helps: http://www.amazon.com/RCA-F27TF720-T.../dp/B00006JBKG RCA no longer seems to have it on their own website.
