Understanding the Issue: Red Light but No Start
Before we dive into troubleshooting, let's understand what might cause a TV to turn on but have no picture or sound. When your TV is plugged in and turned on, it should display an image and produce sound through its speakers.

Faulty Power Supply: The power supply unit (PSU) may not be functioning correctly due to wear and tear over time.
Damaged HDMI Cables: Faulty HDMI cables can prevent video signals from reaching your screen.
Dead Pixels or Screen Damage: If individual pixels are damaged within the screen panel, they won't display any images.
Software Issues: Firmware problems might lead to graphical errors like black screens while still consuming power.
