Television Repair Guide

In recent years, TVs have changed dramatically. It’s hard to remember a time when television screens were more than 4 inches thick and non-HD displays seem like a distant memory. Buyers are inclined to jump on the bandwagon as soon as a new UHD, 3D, or LED-backlighting unit is brought out.

With the TV being such an integral part of so many homes and often a rather expensive purchase, it can be worrying when they start to fail. This article will guide you through what to do if your television has stopped working properly.


Things to consider when having problems with your television?

As technology advances and improves, television sets are usually the first household appliance we choose to upgrade. In most cases, homeowners quickly throw out or donate their old but perfectly functioning televisions in order to get a new, more capable model every few years.

For this reason, few television sets usually live out their whole functioning lifetime in a single home. There are still those, however, who choose to keep hold of their older TV until it physically breaks before getting a new one. In other cases, your television set may simply stop working sooner than you had anticipated, leaving you wondering whether it may be worth repairing it instead.

DisplaySearch have found that the frequency in which we upgrade our TVs increases year on year. In their multinational study, they found that the average age of a TV when it is replaced has decreased, showing owners are more inclined to ditch their sets sooner.

An important factor to consider (along with screen size, picture resolution, and other aesthetic factors) how much energy your older television set is using to bring you your favourite shows.

Let’s say that you had two televisions in your home that were being used an average of four hours a day. If one uses around 100 watts and the other uses 160 watts, that equates to just over a kilowatt hour being consumed each day. Given a cost of roughly 8p per kilowatt hour, this would cost just under £30 a year to power.

The age of your television can make a huge difference to your energy bill. According to the Consumer Electronics Association (CEA), LCD flat-screen TVs of between 35 and 54 inch screen widths built between 2005 and 2007 use 250 watts of power.

Their studies show that the average active mode power use of more modern sets now is closer to 100 watts; suggesting you could save as much as 150% of the cost to power your TV by upgrading to newer model.


Detecting and identifying faults with your television

Here are some of the most common issues you may be experiencing with your television set and how to diagnose a genuine problem:


TV won’t turn on or taking a long time to turn on

If your television is not responding when you try to turn it on, while it may sound obvious, first make sure that it is definitely plugged in to your electricity mains and turned on at the socket.

If your TV still won’t turn, this is a sign that there is an electronic fault in the components.


TV turning itself off

If your unit has a habit of switching off on its own accord, it is likely there is a problem with either the power board or the main board within the TV.


No picture coming up on TV

LCD TVs may struggle to display your picture if there are faulty LED strips within the screen. These can be easily repaired or replaced by a trained expert.

If your plasma television is experiencing the same problem, it is likely there is a problem in the circuit boards. Older rear projection televisions can also fail to display pictures if the internal lamp needs replacing.


Lines on the screen or missing pixels on TV

This is a common fault if your screen has been knocked or damaged in some way, and this would often mean the television needs to be replaced. If you are not aware of any physical damage, it may be a problem in the circuit boards in the machine which can be replaced.


TV freezing picture

Don’t be too tempted to get a new television set if your existing screen keeps freezing. That’s because, more often than not, this is due to a faulty aerial rather than the actual unit.


No sound or issues with sound quality

Sound problems can arise from both the televisions main board or the actual speakers within your TV. The latter is rarely the case, however, as even if one speaker fails the other should still work.


TV remote not responding

If you have changed the batteries in your controller countless times and it still won’t work, there could be a fault in either the remote itself or in the IR sensor within your television.


TV not connecting to the internet

Many televisions nowadays are designed to connect to the Wi-Fi in your home. If wireless is not working, you should try to connect the television with an ethernet cable. If this still does not work, it is possible it has a faulty main board.


Potential repairs and costs for your television

As you can see above, many of the most common television problems are the result of a fault in the unit’s circuit boards. That is why, if you choose to repair rather than replace, you should always have a highly trained expert complete the work.

If your television is still under warranty, you can approach the store you purchased from should your TV need repairing. There are, however, also a number of TV repair experts that are qualified in fixing virtually all problems with LED, LCD, and Plasma TVs.

These services will often have a single, fixed labour for repairing your TV, then ask for you to pay for the parts they used. For example:


Type of repair: Cost: You’ll also get:
One-off TV repair £95 plus parts 12 month repair guarantee for the exact fault repaired


Should I repair or replace my television?

If you are experiencing persistent problems with your TV, it may be worth having it repaired by a highly trained expert. In the majority of cases for new and high-value sets, this is often much better value for money than replacing it entirely.

Many retailers offer extended warranties at 15% of the cost of the item for larger electronics like TVs. This can greatly reduce the amount you pay should a problem arise.

An important thing to note is that you should never attempt to repair a television yourself. If the TV is still under warranty, this could mean you lose your cover. On top of this, DIY electrical repairs are incredibly dangerous and trying to fix it yourself could result in a fire or an electric shock when the unit is switched on or cause other problems further down the line.

The general rule is that if a repair costs more than 50% of the price you could buy a new one for, you may be better to replace.


What to look out for in when replacing your television?

If your TV is beyond repair or you simply wish to upgrade, make sure you know exactly what you are looking for before you start to shop around.

Sales assistants will often talk about a lot of features that don’t apply to you to try to get you to buy, so make sure you do your homework beforehand. Set your own budget, decide on a screen size, and pick which features you really want to help you narrow down your search.

Also ensure you choose a television with an extended warranty through the retailer to save money should you have TV problems in the future.
