If you’ve recently experienced the frustration of staring at a blank blue screen while trying to enjoy your favorite show, you’re not alone. This common issue can leave viewers perplexed and anxious about potential repairs or replacements. A blank blue screen on your TV can arise from various causes, ranging from minor technical glitches to more significant problems with your hardware or software.
