Haier Tv Not Turning On

Having trouble getting your Haier TV to power up? Don’t worry – this step-by-step guide will help you diagnose and fix the most common issues preventing your TV from turning on.

As a technician with over 10 years of experience repairing consumer electronics like Haier, Samsung, Sony, Sharp and TCL TVs, I’ve seen every possible problem that can stop a television from working properly. By methodically working through the troubleshooting tips below, you’ll get to the bottom of what’s wrong – and have your TV working again in no time.

Why Your Haier TV Won’t Turn On

There are a few main culprits for a Haier television that will not power on:

  • Power issue – No power getting to the TV at all
  • Faulty component – Internal hardware failure of a key component
  • Loose connection – HDMI or other cables not properly attached
  • Remote control – Remote not working properly

I’ll cover each of these common issues in detail in the troubleshooting steps below.

A Systematic Approach to Diagnosing the Problem

Getting frustrated trying random fixes hoping one works? I don’t blame you. But there’s a right way to troubleshoot…

Follow these steps in order to methodically narrow down the cause:

  1. Confirm the TV is getting power
  2. Try resetting the TV
  3. Check all cable connections
  4. Test remote control functionality
  5. Swap out damaged cables or components

Taking this structured approach will lead you to the source of the problem much faster.

Now, let’s dive into the step-by-step process for getting your Haier TV working again.

Step 1: Check Power to the Haier TV

The most obvious issue stopping your TV from turning on is a lack of power getting to the unit.

  • Make sure the TV is plugged directly into the wall outlet. Remove any power strips, surge protectors or extension cords temporarily to eliminate them as a factor.
  • Try connecting a different device like a phone charger to the outlet to confirm power. If the outlet doesn’t power the test device either, you likely have an external issue with your electrical system or circuit breaker.
  • Inspect the power cord carefully for damage. Exchange for a new power cord if there are any cuts, loose connections or bent plugs.
  • If the standby light illuminates but turning on the TV via remote does nothing, this indicates there is power getting to the unit but an internal component failure is preventing full activation.

Confirming where power is lost is the first step towards narrowing down where the root cause lies.

Step 2: Reset Your Haier Television

Before diving into hardware repairs, try restarting your TV with a simple power reset:

  1. Unplug TV from power source
  2. Press and hold the power button on the TV unit itself for 10-15 seconds to discharge residual electricity
  3. Let the TV sit for 2 full minutes before plugging back in
  4. Connect power cord and press power button

This forces a hard reboot and flushes any corrupted data or glitchy software that could be preventing start up. I recommend a reset as step 1 for any electronic that suddenly stops functioning properly.

Step 3. Inspect All Video and Data Connections

If your TV powers on but doesn’t show video or sound, loose cable connections could be the issue.

Check for any loose or disconnected:

  • HDMI cables
  • RCA or component video cables
  • Optical or RCA audio cables
  • Antenna/coaxial cable

Remove each cable and reconnect firmly into port on back of TV, then TV power reset after reconnecting everything. This re-seats any temperamental connections.

Inspect cables for damage as well – a single disconnected wire inside the cable can cause handshake issues between devices leading to no video/audio. Exchange damaged cables.

Step 4: Confirm Remote Control is Operational

Can your television turn on via the manual power button but NOT using the remote control? That is a strong indication of remote failure.

  • Check remote control battery levels – Replace batteries with brand new ones
  • Make sure remote has direct line-of-sight access to IR sensor on front of TV
  • Try using remote with different device (Blu-ray player, cable box) to confirm it works
  • If available, test with alternative remote control to isolate problem

If remote tests functional, then IR sensor failure within the TV could be preventing communication and activation via remote control. This requires internal component testing and replacement.

Step 5: Diagnose and Replace Faulty Internal Hardware

If you’ve made it through all the previous troubleshooting steps, the TV likely has a fault with an internal electronic component that will need replacement.

Common at-fault parts that prevent successful power on:

  • Power supply board
  • T-con board
  • Main logic board

Confirming exactly which piece failed can take specialized diagnostic equipment and circuit-level troubleshooting expertise.

At this stage I recommend partnering with a qualified TV repair technician for fastest resolution. Replacing damaged internal electronics markets requires soldering know-how and specialty tools.

Generic replacement power boards and main logic boards are available on eBay and Amazon for many Haier TV models at reasonable prices. Get the exact part number off the damaged board before ordering a replacement online.

If the TV is outside of warranty, repair costs can approach 50-75% of a new TV price, so assess expenses before proceeding.

Keep Your Haier TV Running Like New

Avoid future turning on issues by keeping your television clean, maintained and stored properly when not in use:

  • Keep TV away from dust, liquids and direct sunlight
  • Use compressed air to routinely clear ventilation openings
  • Allow 4-6 inches clearance around the unit for airflow
  • Unplug TV before thunderstorms to avoid power surges
  • Install the TV on a sound, level surface so it doesn’t tip
  • Avoid using spray cleaners or liquid cleaners on the display
  • Use a soft, dry lint-free cloth to wipe dust from television

Following these care instructions helps prevent damage and prolong your Haier television lifespan significantly.

When to Call in a TV Repair Expert

As outlined above, many turning on problems can be resolved with basic troubleshooting or affordable component replacements.

However, if you are uncomfortable working inside modern HDTVs (which contain sensitive electronics), or repairs exceed the remaining value of the TV, calling a certified TV repair technician is the best option.

Here are a few indicators it’s time to hand over the job:

  • You followed troubleshooting guide but problem persists
  • Don’t have right tools or skillset for internal electronics work
  • Unsure exactly which component requires replacement
  • Repair costs too high compared to purchasing replacement TV
  • Additional issues or faults identified during inspection

Trusted TV repair techs have the sophisticated diagnostic tools, parts sourcing channels and specialized expertise to get you up and running quickly and painlessly. They should also offer free quotes for the job prior to starting work.

Conclusion and Next Steps

I hope this comprehensive troubleshooting guide gives you confidence to tackle any finicky television brand (like Vizio, Philips, Samsung etc.) that refuses to turn on properly. The methods outlined here can be applied to many models and makes of TVs.

Methodically working through the power tests, cable checks and component replacements outlined above will get your TV functioning like new again in the majority of cases.

For any remaining issues past these steps, leverage a professional TV repair service to finish the job right. Taking advantage of their parts discounts and technical skills will have you back watching your favorite shows at minimal expense.

Now you have the knowledge needed to troubleshoot AND when it’s the right time call in the experts. Here’s wishing you the very best in getting your pesky Haier television operational once more.
