8 year old model, which one?
You may be surprised at the price of an close equivalent(without 3D) tech has moved on a lot.

There may be a 3D second hand from a couple of years ago Panasonic were still doing a decent one(it was on my short list but went OLED).

You could try the model users thread on AV forums if it is a common fault they may be able to point in a direction.  

whenever asking about something the model number is always worth posting.

The TV is a Samsung ue46d8000. I know new TVs likely have the same or better picture quality but we have a ton of 3D movies and enjoy watching them. 
Have considered a 2nd hand TV but they seem few and far between at that size.. And they have to have freesat as we don't get Freeview here. . So unless it's built in we'd need a freesat box too!
And then we could pay out for a second hand only for it to also break in a few months, at least new they have a warrenty. 

Its so irritating.. I just like our TV!

Search for "Samsung ue46d8000 intermittent backlight" and you'll find loads of hits.  Not all will be relevant but they might give some clues. 
Just take it slowly and carefully, don't work on it with kids and/or pets around, don't allow any distractions.  If you really HAVE to prod around inside, take off your watch and any rings, use insulated tools (preferably VDE-rated) and keep one hand in your pocket (yes really, look it up if you don't believe me https://www.dummies.com/programming/electronics/avoiding-electric-shocks/ ). 
Also, remember that PSUs can retain some voltage even when switched off so behave accordingly.
