Can these lines be fixed?

Noticed these lines and stuck pixels on my trusty old Samsung last night and I'm hoping there are some tricks to try and bring it back to normal

The lines run all the way to the screen edge and the pixels go red on dark scenes.

If there isn't a way to fix it can anyone recommend a budget 40" TV as that is the max size I can fit in the space available. It's a second TV used mainly for TV but also occasional gaming, I've seen some 4k screens come in at under £300 but they all seem to be rebranded chinese models.

Like this:

That's available for £263 while the ebay promo runs.

So are these cheap 40" 4k TV's just terrible or worth a punt for sub £300?

Damn missed out on a decent priced Samsung UE40MU6400 refurb which would have been ideal.

The state of the 40" market is crazy, has everyone suddenly got bigger bedrooms or something. A 50" screen would look ridiculous where this needs to go, even if it did physically fit.

I think the only way you could fix it is if you got a replacement panel under warranty, it looks pretty terminal otherwise.

Sadly it's long past any warranty.

Cant seem to find any proper reviews of that sharp I linked to above. From what I've read 4k is pointless at this size and hdr is poor at this price range. However there arent many 1080p sets at this size either so really limited for choice.

I’d up your budget to around £400 tbh

Samsung UE40JU6740

Have you seen that for sale anywhere as all the retailers I've looked at show it as end of line.

Screen size has a lot to do with the economics of LCD panel substrate. This is the big sheet of LCD material that the individual panels are cut from.

Successive generations of manufacturing machinery makes it possible to produce larger sheets and therefore bring down the unit cost per panel. The panel manufacturers want to cut as many panels from a sheet as possible to reduce waste, so it may end up with a situation where it's cheaper to cut 43" glass from a later generation substrate than it is to use earlier gen' plant to make 40" screens.

Supply agreements also come in to it though. There may be ongoing contracts for certain screen sizes, and price renegotiations at the point where demand for 40" panels falls. This would rebalance the cost equation.

We shouldn't overlook consumer trends either. Given the option of a larger screen at a similar cost as a 40", most consumers will opt for bigger.

Yeah I can understand why the manufacturers have moved that way, especially as anything under 55" seems a bit pointless 4k wise but you'd think they would still be targeting the smaller bedroom size in some form.

It seems my only real choice is these budget models, I'm tempted to just get the Sharp I linked at £263 as it looks unlikely that anything will be released at this size from the main brands when new models come out.
