Issue	Possible Solutions
No Picture or Sound	Check power cord connection. Verify correct input mode. Ensure antenna is properly connected. Check if the main power switch is on. Make sure volume is not muted or set to minimum. Ensure headphones are not connected.
Picture is not clear	Check antenna cable connection. Verify TV signal reception. Disconnect other peripherals if connected (e.g., VHS). Consider antenna obstruction (for ghosting/double images); use a directional antenna if needed. Turn off or remove sources of electrical interference (e.g., hair dryer, neon lights).
Picture is too dark, too light or tinted	Check colour adjustment. Check brightness setting. Check sharpness function. Consider if the fluorescent lamp has reached the end of its service life.
Remote control does not work	Check remote control batteries. Ensure the remote sensor window is not under strong fluorescent lighting. Clean the remote sensor lens with a soft cloth. Use the TV's buttons (hotkeys) as a temporary solution.
