What I Like...

is flat screen CRTs. Not many people like them because they're deep being around a 70 degree deflection tube (much like the very first CRTs).

I have to admit that I don't care for the picture on an LCD TV. They're fine for computer monitors, but I've never seen an LCD TV I liked. They just seem to lack a certain something which gives them a fake look.

A good LCD projector if fine, and plasma looks very film like to me. My initial impressions of OLED is that looks better than anything I've seen before, but I have only seen them in stores.

As far as reliability goes, it's wayyyy overblown. My Dad has a couple of Panasonic plasmas that have seen heavy use for about the last 7 years without a single problem. My Mom has an LG plasma from 2008 that just needed a few power supply caps earlier this year. My brother has a 2010 Panasonic plasma that's never had a problem.

All that compares similarly to the later model CRT sets that were in the family (mostly reliable with one or two minor failures).

Two CRT sets I bought new (79 GE, 90 XBR) needed repairs within a couple years, neither of my Panasonic Plasmas (2008, 2014) has had an issue. Neither did the 2005 Sony LCD Rear Projector. (replaced by the Plasma)

I have a 2007 Samsung LCD that I got with a bad PS cap and repaired, it's been running fine since 2011.

My two HP LCD Monitors from 2007 have never had a problem and they probably get more use than the TV's, the one I'm using now has 13,000 hours on the back light, the monitor itself is always on.

Older CRT sets were probably more easily repaired and parts more available, but that has more to do with the manufacturing process than anything else.

One problem flat-screen TVs with LED backlights cannot have is inverter failure, as LED backlights do not need an inverter as do FPs with CCFLs in that position. That's one less thing to worry about going bad.

VK member andy makes a very good point regarding the reliability of flat screen TVs. I agree with him that the reliabilty issue has been overblown. As I have mentioned before in previous posts, my Insignia 19" LCD flat screen is five years old now (it was manufactured in May 2011) and is still working every bit as well as it did the day I bought it. I am expecting it to last a few more years, but if it doesn't, I have my 20-year-old Zenith Sentry 2 ready to replace it.

I think flat screens, which have been with us now for some time and have all but completely replaced CRT sets in American and Canadian homes, have come a very long way from the very first ones, which often did fail within two years or less (!) of initial purchase. Today's FPs, except the very cheap no-name ones (Polaroid, Element, Craig, et al.) found at CVS, Rite Aid or bargain-basement discount stores, are much more reliable, with most issues stemming from design flaws and/or from the use of very cheap (read $.05 or even less) capacitors and other parts. These are much more likely to be damaged beyond repair by lightning strikes and other electrical hazards, although any TV (FP or CRT), even the expensive large-screen ones, or other electronic device can be damaged by a close strike and certainly by a direct hit on the AC line from which the set is powered, or a strike on a cable line, although of course the cable box (if used) will likely be damaged first if lightning hits the cable.

Yeah, I agree that is one positive thing with DTV. I live in Tiltonsville, OH, moved here to be closer to my gradeschool buddy after I lost my mother in 2013. I live in the Ohio River Valley and I only get two TV station over the air, but at least both have 1 main channel and 2 subchannels. WTRF in Wheeling on 7 carries CBS as their main channel and they have ABC on a subchannel and another channel as well. ABC does not come into the valley too well since the closest affiliate is in Pittsburgh and WTAE, channel 4, does go far very well. The other station is WTOV, channel 9, in Steubenville, I get NBC, Fox and MeTV on there. MeTV is what I watch 90% of the time.

You can still get all three major networks since channel 7 carries CBS, channel 9 is NBC, and channel 7 has a subchannel that carries ABC, so you don't have to worry about whether or not the ABC affiliate in Pittsburgh reaches your house. I don't know whether you can get PBS where you are (I think the closest PBS affiliate to you might be WQED in Pittsburgh), but since PBS affiliates are usually much weaker than commercial TV stations, the Pittsburgh affiliate may not reach you unless you have a powerful antenna.

BTW, I was glad to see your post, as I often wonder how you are since your mother died and you moved to southeastern Ohio three years ago.

Also, I hope your cats are OK. My own cat, Kiki, is going to be ten years old very soon (I've never been sure exactly when she was born, only that it was some time in 2006; I got her from an animal shelter near here when she was just three), and is doing quite well; affectionate, likes to stay close to me every chance she gets, and so on. I couldn't ask for a nicer cat.

I was thinking about you the other evening when I was watching my 20-year-old Zenith 19" CRT TV (I wanted to see if it still works, as I don't use it much anymore since getting my flat screen set in 2011).

Do you still have your Zenith console you had when you were at the other house, and if so, how is it working now? Those older Zeniths were built like tanks. My CRT set is living proof of that. I've had it 20 years, and it still works every bit as well as when it was new in 1995. Even has its original CRT, which still makes an excellent picture. I mention the tube because my set was made during the era when Zenith televisions had "bad" CRTs that would short after about two years, taking the video output and at least one other circuit at roughly the same time.

I've been seeing a lot of cheap LCD sets with bad LED backlights, so I've got my doubts that they'll last longer than CCFL backlights. These have all been under 3 years old (some only just outside of warranty). In these sets the backlight is one string of LEDs in series, so when one fails open the whole panel goes dark. I've yet to attempt to repair the backlight itself. I get enough of these sets with cracked LCDs that I just swap the entire backlight.

I've got quite a few 10+ year old panels with CCFL backlights that are still going strong (though I do have a stash of replacement inverter transformers for a couple that I'm particularly fond of).

LED failures aren't restricted to TV backlights. I was in a building recently full of those 3 LED downlights and every room had at least one out.

But, but, but... LEDs are supposed to last forever, aren't they? They told us we will never have to replace them. They told us they are the wonderful, magic, perfect, green solution that will save the planet and cure all the ills of the world.

Seriously, though, I have observed the exact same thing. I've also noticed their brightness fade over time.

In my house, I joke that we have a reverse incandescent light bulb ban -- anything that ISN'T incandescent is forbidden.

LED lighting is awesome, but like any commercially made product there's variations in qa/qc which can affect your experience. I personally wouldn't specify anything else for new construction in most instances.

I hoarded incandescent bulbs when they announced the ban, not because they're superior but because I didn't agree with the government telling people what they can't and can't buy.

Those 3 LED halogen replacement bulbs may well be a particularly cheap/poor quality type - likely supplied to the building for free under some government energy saving initiative. At least they're easy enough to replace.

I don't like the ones that are sealed and the whole fixture has to be replaced when it fails (and by a licensed electrician, at least officially).

I've actually repaired a couple that were flickering by resoldering dry joints on the driver board, but to get at the board I had to drill out all the rivets.

Has anyone seen the new OLED displays from LG? Astounding. Best picture I've ever seen.

That's not an issue for LG's system because instead of red green and blue OLEDs, they use white OLEDs with color filters. It's less efficient, but since it's the same OLED material for all three colors, they age uniformly.

They are still expensive, but the price is dropping quickly, and they've finally started to sell flat ones in a normal form factor that can be wall mounted. I hope they eventually start selling smaller TVs and computer monitors. Ultimately, they should be cheaper to make than an LCD if they can work out the manufacturing problems.

Samsung made an OLED TV that had RGB OLEDs, but it was only on the market for a short time. I'm not sure how they have aged.
