I started working for my current employer in 2003 42" plasmas were still £5000 LCD was in its infancy and a 19" was nearly £2000 and the pictures on early LCD's were awful CRT' s were far better.
Now we are selling OLED TV's starting at just over £1000 and 75" 4K LCD's for under £1000.
It does make me wonder about the quality of components going into modern products.
My own TV a Samsung UE49RU8000 died after 14 months, needed a new main board at a cost of £100, thankfully no labour charge as it was repaired at work.
The TV that I had previously a LE40C550 - that was 10 years old at the time of buying the UE49RU8000 - I gave away and is still going strong, now 15 years old.
