LG turns a bad TV story into a (potentially) good one

LG’s updating one of its popular LED Smart TV ranges after our testing revealed a sound fault was so bad we had to make it a Don’t Buy. And, if you’ve already got one, LG’s offering to send an engineer out to fix it.

Sound quality comes second to only picture quality for most of us when buying a new TV. So, ending up with a model that buzzes and reverberates when listening to voices speaking is a pretty big no-no.

At Which? we make every effort to go the extra mile in our testing. That means when we find a problem, not only are we able to tell you not to buy it, but when it’s an issue we feel is so bad it must be a design fault, we take it back to the manufacturer. Firstly to let them know about it, and more importantly to see what they’re going to do about it.

Which? TV testing

That’s why I’m very encouraged to see manufacturers going the extra mile in response to our verdicts. When we met with LG to alert the company to the sound issue with its 32-inch LED Cinema 3D TV (the 32LM620T to be precise) it came back to us in just over a week.

Its engineers had been hard at work investigating the problem and found the sound issue was not caused by the speaker units, but by the way they had been mounted in the TV casing.

LG assured us that it had looked at all screen sizes in the LM620 series – not just the 32-inch version we’d tested – and all models leaving the factory will be updated from now on (hitting shops in mid-October). LG’s customer services teams have also been made aware of the issue and will send an engineer out to mend any TVs that are reported to have this fault. And most importantly, they’ll do it for free.

LG respond to concerns

It shows that quick responses from big companies are more than possible. It’s great to see manufacturers taking action to make sure customers are not getting a raw deal. Obviously it’s good for them too – what manufacturer wants to be known for selling a rubbish product?

But while I’d like to applaud LG for its swift action, this is with the caveat that we haven’t yet tested the newly improved version. We’ll do this as soon as it hits the shops in mid-October.

We often hear about bad customer experiences, but have you got any of your own examples of companies going the extra mile?

If you think you’ve got one of the affected TVs you can call LG customer services on 0844 847 5454.


That looks like a quick win. Well done Which?

Now we need to have a proper phone number for LG, rather than expecting customers to pay LG money to discuss their problems by using an expensive 084… number. There is a geographical number but a note saying that this cannot be used to contact Customer Services. Sorry, but that’s not good enough, LG. I think we need your help again, Which?


01753 491500 and ask for executive care team – see my comments below.

Thanks for this. However, when I called this number all I heard was a continuous buzz. Surprise surprise! LG avoiding customer complaints I wonder?


The person who comes to fix it is an engineer?

I bet you they’re not.


So a manufacturer makes a product that is clearly defective, they admit the defect and agree to sort it out free (of course they should, why should the customer pay) and this is described as taking swift action and is praised.
What I think this really shows is that expectation of customer service has fallen so far that by doing the ‘right thing’ it is seen as exceptional when in reality it is the least that would be expected.


I agree that expectations of customer service have fallen. I’m even more concerned about goods that are unreliable and difficult to repair economically.

I reckon that TV manufacturers should offer a ten year guarantee on TVs, covering both parts and labour. That should ensure that the build quality and quality testing is greatly improved.

I believe that it is fair to praise LG because they are honouring their responsibility, which is more than some manufacturers do.


My sentiments entirely! Thank you for your comments.


Unfortunately my experience with LG isn’t so positive. When I queried why I wasn’t able to switch my LG 32LF7700 LCD TV on when I had a computer connected to it via the VGA port: I was told –

“Based on the information you have provided me with and reading through your query, I can advise you that as inconvenient it may be yes this is normal. As the two will not automatically configue the resolution settings on start up. Also a computer is only meant to be connected to the television for the time of use.”

i.e. you have to plug and unplug the computer (at the back of the TV – just disconnecting at the PC end didn’t resolve it) when the TV is ON to use a PC via the VGA port. This is about as practical as a chocolate teapot if you have a media PC or have the display mounted flat against a wall.

I did get around the problem using a display port to HDMI connector at extra cost and the loss of audio playback through the TV which is inconvenient to say the least.

In the case described at the top it took the intervention of Which to point out and resolve problems – without it your normal punter is probably left out in the cold with spurious explanations and a general feeling of being hoodwinked.

I have phoned up LG just now re this, 18 minutes on the phone. They are NOT (they claim) aware of any fault on this tv.
They refused to read this website and the which report and stated that they have no known faults on this model.
Complete joke!
