7 Things to Check Before Calling TV Repair Service

Hello there! Have you ever turned on your TV only to find that it suddenly stopped working, and your first thought was to call a repair technician right away? Before you pick up the phone, take a deep breath — some issues can be solved easily at home. In today’s post, we’ll go over 7 essential things to check before calling a TV repair service. By following these steps, you might save time, money, and even learn a few tech tricks along the way!


1. Check Power Supply and Cables

Before assuming your TV is broken, start with the basics. A surprising number of “dead” TVs simply have loose or disconnected cables. Ensure the power cord is firmly plugged into both the TV and the outlet. If the outlet is controlled by a switch, verify that it’s turned on. Try plugging another device into the same outlet to confirm there’s power.

If you’re using a surge protector or extension cord, check that it hasn’t tripped. Many surge protectors have small reset buttons — press them to restore power if necessary. Additionally, inspect HDMI and AV cables to make sure they’re not damaged or loose.

Issue Possible Cause Quick Fix
No Power Unplugged or faulty outlet Plug in securely or test outlet with another device
Intermittent Power Loose cable or surge protector reset Tighten cable or reset surge protector
No Signal Disconnected HDMI or input cable Reconnect cables and select correct input

2. Inspect the Remote Control

Sometimes the TV is working fine — it’s the remote that’s the problem. Before calling for repair, check your remote control. Replace the batteries with new ones, making sure they are inserted correctly. If it still doesn’t work, try using your smartphone’s camera to check the infrared (IR) signal. When you press a button, you should see a light flashing through the camera.

Additionally, make sure the remote sensor on the TV isn’t blocked by dust, stickers, or other objects. You can also test the power button directly on the TV itself to confirm if the issue lies with the remote or the television.

Pro Tip: Universal remotes or TV control apps can help you test the functionality before assuming the remote is broken.

3. Verify Input Source and Settings

Modern TVs have multiple HDMI and AV inputs, which can easily cause confusion. If your TV displays “No Signal,” make sure the correct input source is selected. Use the Input or Source button on your remote to cycle through options like HDMI1, HDMI2, or AV.

In some cases, devices like game consoles or streaming boxes may be in sleep mode or powered off. Wake them up or restart to check if the connection resumes. Additionally, double-check that your TV settings haven’t been reset or changed accidentally — factory resets or firmware updates can sometimes alter configurations.

Lastly, verify that the brightness or picture settings haven’t been set too low, giving the illusion of a black screen.

4. Look for Screen or Backlight Issues

If your TV turns on but the screen is dark or flickering, the issue could be with the backlight or display panel. Shine a flashlight closely on the screen — if you can faintly see images, the backlight might be malfunctioning. This is a common issue for LED TVs and usually requires professional help.

However, before assuming the worst, check for loose connections between the main board and display panel. Sometimes, gentle cleaning and reseating cables can make a difference. Also, turn off any “energy-saving” modes that might dim the screen excessively.

  1. Dim or Black Screen: Possible backlight failure.
  2. Horizontal Lines: Cable or panel connection issue.
  3. Color Distortion: Try resetting picture settings.

5. Compare Common Problems and Fixes

Before rushing to a technician, it’s smart to understand whether your issue is common and fixable. Many TV problems have simple DIY solutions that don’t require a repair bill. Below is a comparison of typical symptoms and potential solutions.

Symptom Possible Cause Recommended Action
TV Won’t Turn On Power issue or main board fault Test outlet, try unplugging for 5 minutes
No Sound Muted or incorrect audio output Unmute or check sound settings
Distorted Picture Signal interference or cable damage Replace HDMI cable or reset TV
Tip: Always check your TV manual or manufacturer website for troubleshooting steps before requesting service.

6. Estimate Cost and Find Reliable Services

Once you’ve verified all the steps above, and your TV still doesn’t work, it may be time to contact a repair service. However, before making that call, research the average cost of common repairs to avoid overpaying. Here’s a general breakdown:

Repair Type Estimated Cost (USD) Difficulty
Backlight Replacement $100–$200 Moderate
Main Board Repair $150–$300 High
Screen Replacement $400+ Very High

When searching for repair services, check customer reviews, certifications, and response times. A good technician will diagnose the problem first and provide a written estimate before proceeding. Avoid services that demand full payment upfront or refuse to explain the issue clearly.

7. Frequently Asked Questions (FAQ)

How do I know if my TV is worth repairing?

If the repair cost exceeds half of the TV’s current value, replacement is usually the better choice.

Can a TV be fixed if the screen is cracked?

In most cases, cracked screens are not repairable and require full panel replacement, which is often expensive.

Why does my TV turn off by itself?

This can result from overheating, power-saving settings, or faulty capacitors on the main board.

How long do LED TVs typically last?

With proper use, LED TVs generally last between 7 to 10 years before major issues appear.

Should I try to open the TV myself?

It’s not recommended unless you have technical experience. Opening a TV can void your warranty or cause injury.

What’s the best way to find a trustworthy repair technician?

Check reviews on verified platforms and ensure they provide written diagnostics and transparent pricing.

Final Thoughts

Before you decide to call a TV repair service, a few minutes of careful checking can make a huge difference. Many issues are surprisingly simple — from unplugged cables to incorrect inputs. By following these seven steps, you might not only save money but also feel more confident handling minor tech issues at home. And if repair is needed, at least you’ll know you’ve done your homework first!
