A television that won’t turn on is certainly fixable in most cases, though the solution depends on identifying and addressing the underlying cause. This problem ranks among the most common TV issues, ranging from simple fixes you can do yourself to repairs requiring professional expertise.
Start troubleshooting by checking the most obvious culprits. Ensure the TV is plugged into a working electrical outlet by testing the outlet with another device. Check if the power cord is firmly connected to both the TV and outlet. Examine the power cord for visible damage like fraying or cuts. Try a different power outlet, preferably one not connected to a wall switch that might be off.
Test your remote control by replacing its batteries and ensuring nothing blocks the TV’s infrared sensor. Sometimes the TV is actually on but the screen appears off due to extremely low brightness settings. Alternatively, use the power button directly on the TV itself rather than relying on the remote. If the TV powers on this way, your remote needs attention rather than the TV.
Perform a power cycle by unplugging the TV, pressing and holding the power button for 30 to 60 seconds to discharge residual electricity, then waiting a few minutes before plugging it back in. This simple procedure resets the TV’s internal components and resolves many temporary glitches.
If these basic steps don’t work, the problem likely involves internal components. Power supply board failure is the most common cause of TVs that won’t turn on. This board converts AC power from your outlet into DC power needed by various TV components. Failed capacitors, burnt components, or damaged circuits on this board prevent the TV from receiving adequate power. Power supply repairs typically cost between KES 2,000 and KES 8,000 depending on TV size and brand.
Main board failures also prevent TVs from powering on. The main board functions as the TV’s brain, controlling all operations. When it fails, the TV becomes completely unresponsive. Main board replacement costs vary widely from KES 3,000 to KES 15,000 based on TV model and part availability.
Fuses and surge protectors inside the TV can blow during power surges, preventing the TV from turning on. Replacing these protective components is relatively inexpensive, usually under KES 2,000. Other potential causes include failed backlight inverters, damaged T-Con boards, or internal wiring problems.
Professional diagnosis becomes essential when basic troubleshooting fails. Qualified technicians use multimeters and specialized tools to test components systematically, identifying the exact failure point. Most TVs that won’t turn on can be economically repaired, making professional assessment worthwhile before considering replacement.
