My Toshiba 50HX70 has served me well over that last 4.75 years. My 5 year warranty is about to run out soon! The last few months I noticed I get B&W pitures sometimes on all channels (I have Comcast). After a half hour or so, the color comes back. Sometimes the color flutters in & out. What specific things should I have the HiFi Buys tech check when he comes to the house to fix it, as it's still under warranty? I want to make sure he checks and replaces EVERYTHING that's needed, and hope he won't do a quick temporary fix to hold me until the warranty runs out in a few months. Then, I'll have to buy a whole new set which I can't afford anytime in the near future. Thanks for any help or suggestions.
