Do more lcd/plasma screen TVs go wrong compared to CRTs?
I'm curious to know, and what are your experiences?
I'm just wondering as there is always a lot of posts here on DS about 3 ish year old lcd/plasma tvs breaking down and screens dying, people needing new inverters etc. Where as the crt tvs I have had have been around 15 years old and still working.e.g. my best tv is a B&O mx4000 and that was 1992 and it is still great. Has the mass production of cheap tvs lessen the quality? or not? |

You're average entry-level 32" TV price has remained about the same - £300 or there abouts....but now the feature set is much higher. Fuel, raw materials, taxes and wages have all risen. So where have they saved the money? On quality, quite obviously. |

Maybe, I have seen poor quality pictures on cheap LCD TV's. My mother has a Toshiba 42inch LCD TV for 3 and a half years, and we have had no problems with it. (TouchWood), I have a Panasonic 32inch CRT with Pro Logic which is 9 years old and that works as good as when we got it. But we had a Toshiba 42inch Rear Projection which was only 4 years old when we had to dump it because the ON/OFF switch on the front panel broke (got pushed in), we manged to hold the button in with a matchstick because it sometimes sprang out and turned the set off, we put the set on standby and removed the plug from the mains when we were not using it, but that caused the power supply to fail later on.

I had a cheap 14inch CRT colour portable that I got for Xmas 1991. It needed a cheap repair 6 years later. blown internal fuse, it lasted then until 2008 when the power supply went dead and it was not worth repairing, so I sent it away for recycling.

Decent make LCD/Plasma are considerably MORE reliable than decent make CRT sets, and even cheap LCD's are more reliable than cheap CRT's were.
I seem to recall that LCD sets are statistically something like three times more reliable?. Even 30 years ago, TVs could be just as unreliable as cheap ones are now - but I hear they were usually British. TVs like the Sony AE1 chassis models usually lasted years longer than their same-price, same-year, same-market British equivalents. In fact, I'm currently watching a KV21XMTU that I don't think has had any servicing. So all, I don't think it's anything to do with LCD/Plasma vs. CRT, or when the TVs in question were made - the argument seems to go much deeper than that. I'm sure had large screen flat panel sets been in mass production in 1987, then, electronically, they would have been just as reliable as my 1987-ish Sony Trin. CRT TV. (Though a CRT screen would be much tougher than an LCD screen )

I was just curious with a lot of the posts on ds about flat screen tv's dying after about 3 years, but are they generally the vestel models? or not? Im not picking out a brand and targeting them.
A friends Panasonic lcd lasted 3 years, another friends Tosh lated 2 years, another friends flat screen samsung computer screen/tv lcd only lasted a year where as my tv B&O has lasted longer and so did my samsung 10 year old crt and they are both still fine and dandy. Ok my samsung is now at the British heart electrical charity shop, but is on display working. |

Do you see flat screen tvs lasting that long? The longevity of the product. I understand people are updating their tvs more often then we used to due to new tech coming out |

I used to repair the CRT TV's (my job) and I can tell you from experience that the later CRT's were poorly built and unreliable. Beko 14" portables were dire (just a squeak and no pic) and also Toshiba suprisingly (my Gran gor through 3 in two weeks with one being dead on arrival. However, the TV's from around 1988 - 1998 were superb in general with people buing them doing so not on features but brand name and reliability. These were important.
Then the price wars began... |

Old CRT sets like the Fergis was easy to fix, it was all modular to a certain extent, a sound board for sound, another board for this and another board for that. so just unplug one board and replace it, the most expensive part was the tube.
My fergi lasted for 15 years or more, it was my parents first then I had it when I got a bedsit. Very few places will fix T.Vs these days. I hope my philips plasma will last at least another 5 years, it is 4 years old now. |

I remember years back a lady needed a new set, she had a Ferguson (REAL Thorn/Ferguson) that was 20 years old, had never gone wrong, that the tube was simply worn out on. She choose a Sony to replace it, because 'they are reliable'

I have a Samsung LCD in it's seventh year with no problems....I remember CRT's as unreliable because the man from the rental company was always turning up to fix something or another.

My friend had quite a fancy LCD TV for around 3-4 years before that decided to give in and display no picture any longer. I've had a very cheap LCD for about 4 years now and its still going good, however there is a black line down one of the sides but oh well. My auntie had a CRT for a good 10+ years before it finally decided to go green vision and then no longer work.

I had a reliable panasonic until it didn't start any more. It had lasted a decade. The real question is whether cheap second rate crts lasted... I doubt they did. If one had a 36" crt a decade ago Im sure it would have bought several 36" flat panels at todays prices, so even if they did last longer, they cost so much more you didn't come out ahead. |

Back in around 2000/2001 we bought a CRT from Powerhouse (anyone remember that store?) and it was never very good. It had to go in for repairs several times and the picture was never right on it. The sound was also very muffled. It was a Black Diamond brand TV.

The question I have in the future is a LED tv more or less likely to go wrong than traditional LCD TV's?

the strange thing was when my Dad decided enough was enough and we got a colour Mitsubishi, which must have cost DAd a fortune, we had it for over 20 years and not a thing went wrong with it, In fact we gave it a way to a college friend of mine when the guns started to play up and he fixed it and it went on for another 5 years. TBH, i think we been pretty lucky with T.V sets, the worse one my parents had was about 8 years ago a Tatung, a awful thing, the picture would not stay straight. Even my brothers Bush CRT must now be 6 years old and yet stil works fine. |

i9 think LED sets would be slightly more reliable, but only because the LEDs they use to light the screen is more reliable than the tubes they use in LCD screens.
If you go round looking at LED lights on cars and traffic lights, it's pretty obvious that LED reliability isn't anything to 'write home about' ![]() Incidently, if anyone has a Mercedes with LED failures in the third brake light, I've got replacement LED's in stock - a strip of 50 was about £1.20, as opposed to £140 for a new light!. |

It's too soon to have evidence either way, but I would suspect there will be VERY little difference, as most LCD panel failures aren't the CCFL's anyway.

As for MB charging £140 for something that costs £1.20 - that sounds about right. |

It was more likely a cheap Vestel clone, Mitsubishi pulled out of the UK entirely years back - PowerHouse 'imported' cheap Vestel sets badged 'Black Diamond' from Ireland.

I bought a old Thorn/Ferguson 22inch CRT TV from a chap for about £50, He did repairs at his shop. It had the old wood casing, with stereo sound and teletext (not fastext) and a remote control that worked intermittently it was probably an late 70's/early 80's job. It did perform pretty well even though it had flyback bars on the screen that I could only see if the picture was black, and it would either change channels by itself or the volume would shoot up.
I ended up scrapping it ![]() I loved those old fashioned tv sets though. pity I cant find any more like that. |
