Not for me I had a 2017 LG 49SJ810V and it developed very light to moderate vertical banding on the far right hand side so was not a big deal as rest of the panal was clean and all worked
and gave a dam good quality picture. Except I kinda felt 2 years on I was going to do something about it. So I did.
I got in contact with John Lewis as it had a 5 Year warranty with them I purchased it back in September 2017 they sent round a engineer from ICTV services. The engineer said yep it's a fault very light narrow banding I new it was not that bad Compared to how bad banding can get or can be.
Few days later ICTV said LG don't make the Pannals anymore I certainly did not want a refurbished panal not taking the panal "lottery" as the screen did not suffer from any real DSE and uniformity was pretty dam good for IPS.
Sooo I managed my best to have ICTV tell John Lewis in their report to BER the TV so I could then go for a LFL replacement or refund to the value of it now.
Anyways as part of JL warranty they will do their upmost best to replace LFL with what's available now specs wise.
So I pushed for 2019 LG 49SM8600. So I did my homework made sevral calls to ICTV then to JL. Cut along story short being wise and smart all the calls to both companys totaly paid off as of 20th February I'm a proud new owner of a brand new boxed LG 49SM8600 and its bloody awesome TV!!.
All the hardwork and persistentcey truly paid off.
I must state that John Lewis customer service were absolutely 1st rate service. They took away and delivered new TV same day. They called me up next day to ask and make sure things were okay and working.
Also I had to make a small complaint regarding a previous agent gave out some wrong information to be but true to their work a agent from John Lewis customer relations team called me up and as part as good will gesture they have extended my warranty a further 6months.
So I now have untill March 2023. Awesome.
It does pay off to do your homework and be persistent as much as you can all pays off in the end.
Don't be cleaver just be smart about it all get your facts together take some photos if you need to. Make things sound worse than they are it's all key. But don't be rude or shout and scream that will get you know where.
