I usually see worn out LCD TVs go flickery when the CCFLs wear out. I have also seen them go yellow.

The inverter will drive pretty much any tube that is vaguely of the same size and diameter. However, in TVs some use straight tubes and some U tubes. Also, monitors are all edge lit, while TVs vary - some are edge lit, and some are "tanning bed" design (the ones with the boxy panel housing)

Personally I wouldn't bother. If it's a TV set that still uses a CCFL backlight then chances are it will be no higher than 1080p ect.

1080p is plenty for most movies / games / whatever else a TV does

I personally only buy UHD Blu-rays these days and consider 4k 120hz to be a minimum for gaming tbh!

imo 1080p is ample on a 42" set. After a quick bit of research, I think this TV uses straight tubes and lots of them so I guess it's a “sunbed” design as mentioned. I'll do some more Googling and see if I can buy some and if the price is worth it

I have dual 24" 1080p monitors and it's good enough for me. Both LED backlit too.

I have several LCD monitors in different sizes up to 1920x1080. And a 21 inch CRT from 2001 that does 2048x1536 (thats more than 2K !), allthough the pixels in this mode come out smaller than what actually can be represented by the phosphor spots on the screen

I was after one of those 24" Sony Trinitron CRT monitors which could display ridiculous resolutions at 100hz+, some turn up on eBay from time to time but for mega money and also the fact that they are now well over 20 years old is off putting for longevity reasons.

Mine was a trash find, had a HV regulation problem (which resulted in the brightness being shifted way up and not correctable through the menu). Sorted it out by changing a resistor in the voltage regulation feedback

I'd love to find one in the bin but they were all probably supplanted 10+ years ago over here. I did had a big Sun Microsystems CRT years ago for a while that could do like 1600x1200+ at 100hz but at that time my PC could only really manage decent framerates at 1024x768 I got rid of it because my desk was almost collapsing under the weight and went back to a 17" CRT

I have a Samsung CRT in the shed. It's fickery and only works at 800 x 600 when it's native is higher which is strange. Could never use a CRT as my main monitor now though, burn in and their physical size is their main disadvantage.

I would if I could find a decent high-res, high-refresh one as stated above. IMO flat panels have only just caught up with CRT's in terms of colour and blacks with OLED technology but screen burn is even more of a problem on those displays than CRT's! It would look awesome perched above an old 90's desktop case with a Ryzen 9 5900X and RTX3090 in it

How much time you actually have still image, in that one application in which you need the color quality ? I mean, use the OLED or CRT for gaming and LCD (and another computer altogether) for the software with menus and toolbars...

My computer can be on 9-15 hours a day with the taskbar, etc being present most of the time. It’s also on the Lock Screen quite a lot too so if it my monitor was CRT or OLED it would probably be burned in. My monitors are LCD (LED backlit) and neither of them have any signs of burn in. The only thing one of them has done is get a bit patchy but it’s hardly noticeable and it’s nearly 5 years old so I’m not surprised. The colours are good enough for me.

Well after thinking about it for a while, I've just ordered a new LED backlight array for a 42" Hitachi (Vestel) set I have here, so if that works ok once repaired I think I'll have to say this set probably won't get repaired further

I have repaired on the cheap a backlit LED TV for a friend with just 12V LED tape a while ago... (Calculated the voltage current and connected the tape sections in series so, that it runs off the original LED driver built into the TV, while the resistors in the tape have allmost no effect). It worked except having a darker border around the edge. (Doesnt matter, it's used just as a CCTV display anyway)

I've just ordered a supposedly 'new' full set of LED strips directly from China. I'm pretty sure they'll actually be repaired 2nd hand ones, but I'm sure they'll be fine & only cost £18 in total.
The TV itself was free, I picked it up from next to the bins at some flats lol!

The TVs seem to use too few and quite overdriven LEDs, as for the optics they need to put them behind those inverse cone lenses to spread the light

I dunno what to expect from a repaired strip... When i tried to repair a strip in a TV once for my neighbor (smash and solder blob short the bad LED out), it only took a couple months till another one died. The driver is (supposed to be) a current regulated one, so it does not start to overdrive the others like an Xmas lights string. Its just that if one LED EOL'd then the rest are not far behind anyway

CCFL displays take to repairs much better most of the time. (Though for the fact of being CCFL, i put more effort into doing them correctly, while with LED i dont even bother unless it is to help a friend or so)

One of the biggest problems with led backlights is that they're often set way, way too bright from the factory which then cooks the LEDs. Every LED backlit TV I come across I make sure the backlight is set to 50% or less, this is nearly always more than bright enough ...and yes it seems like there should be more LED chips used, although this would cost more money so I guess that's why manufacturers don't
