@Duane: Indeed I enjoy when alone at the end of the day catching up on The News Hour on my tablet (OK I'm a news junkie!)

But I also love nature documentaries--in my heaven they show Planet Earth all day!--and this begs for aan HDTV.

LCD's with CCFL and the 3 year garantee
dgreigml1   12/31/2013 2:08:56 PM
Been caught 2x2 times in the last 6 to 6.25 years with LCD's, "reputable brands".

CCFL's failed 1 to 3 months out of garantee. that was over 800quid of scrap.

It will be interesting to see the longevity of the LED backlights. Ain't optimistic.

My designs are (Weibul, NASA, NPL etcl) aimed for 20 to 25 years with a 6 sigma off the line without repair or touchup.  +100krad, even 150C+ and all the other nasties. Geuss it does not enhance sales but I like stuff that falls out the the box and works reliably. One current ambition is to fall out of the Oak, Pine or Wicker and just fire up again when the time comes.

At least do not watch telly (boring) or use mobile anything (nought much worth saying and, besides anything with less than an 18" screen would be w waste of space). Opinionated! Never worn a watch, use map and compass rather than GPS, larger disply and no batteries, and once one is suffiecently familiar with places the map paper can be used for clensing the nether regions.

For newer television sets I have had great luck with Vizio products and for the typical xmas present, well I have never had a failure with Old Spice.


Now don't even get me started on the terrible washing machines that are available these days.

 I would love to have an old pre 2000 or later year model washing machine and not so much because of parts or quality problems but for me it is the RF pollution that these newer washing machines put out. 

Being a weak signal Moon Bounce ham radio enthusiast, I have found that my wonderful Whirlpool washer puts out more undescriminating RF than an F15 fighters radar jammer, in fact enough RF to even jam the receive side of a local ham repeater that is only 5 miles away.


 Having taken a portable HF/VHF receiver down to the local appliance store I found that every washer that I tried out had sufficient RF spewing out it to the point where it would hold the squelch open on numerous radio frequency bands tested.

HiTech Scrap
DU00000001   12/31/2013 1:30:54 PM
One more ?

We've got a CHP (combined heat and power - in our case driven by a natural gas ICE) - a xxxxx EUR affair.

Setup/startup was done by the company selling this system. Whether they experienced problems: I don't know.

What has happened since installation ?

1. The ICE is supposed to have 3500 h service intervals. What a pity that the oil reservoir does not hold enough oil :( (Or: the ICE is consuming much more oil than planned.) They could exchange the oil injector - if there was any appropriate injector available. Which isn't.

2. During one of the unplanned oil replenishment services I got the message that the control unit is poorly designed (the 'standard' electrolytic caps issue). We'll see how long it will last. Maybe this could be a new business opportunity as the sales company has currently no means to repair the units - just replace with a new scrap unit :(

3. What I nearly forgot: the CHP is leaking water since the very beginning. Retightening of the joints did reduce, but not eliminate the problem.Good thing: underneath is a leakage sump that - until now - did not overflow :)

Rick - You're not quite the last person in America to not have a flat screen TV. The tuner on my old CRT TV died last year. I ended up discarding it with the intention of buying a new flatscreen. As it turns out, I didn't miss the TV, nor did the rest of my family.

Any one of our computers work fine for watching movies and enough media is available online that we really haven't noticed. Every now and then, I'll check out TV prices and features, but, again, decide I don't need one.

>My intention today was to write a lighter, funnier version --and maybe omit the vendor names--oh well!

Not to worry, just tell it like it is.  I tore apart a Samsung microwave back on The Connecting Edge to show the overheated and melted push-on crimp connectors 2 weeks after the warranty expired.  Plus they could not get the parts to repair it.

>I sat the boom box on top of my microwave which really affected FM radio reception when I was using the mic. Could I have irratiated the boom box in some way causing the off button to not work and the small display to die?

Speaking of microwaves, you might want to have the RF shielding tested for leakage.  If it is doing all this to your radio, what might it be doing to your eyeballs?

This was an early draft I did not mean to publish.

My intention today was to write a lighter, funnier version --and maybe omit the vendor names--oh well!


Samsung's local support person called and said two boards were on order for the non working TV. I called back and said cancel the boards. (Who wants a new TV repaired?)

I decided to call Best Buy who said bring the old one in and get a replacement, which I did. They didn't even mind I could not get the TV back in the box because I could not get the plastic stand unscrewed from the display.

It took maybe 10 minutes for them to confirm the old set wan't working and get me a new one.

The new set works!

What does Best Buy do with the old set?

I noted someone had returned an LG 42-inch TV while I was there. These returned TVs must be a pretty big cost for someone! Still less than the cost of a QC person at the factory?

Re the boom box: So far I am limping along by using the AUX button as a virtual off switch. This won't last.

Dumb Question: I sat the boom box on top of my microwave which really affected FM radio reception when I was using the mic. Could I have irratiated the boom box in some way causing the off button to not work and the small display to die?

Samsung products are not so good anyway. I have seen and heard friends complaning about the smartphones that they have bought. Even the LED that i bought is not at par with my expectations or money that i paid. I found old Sony products much better.

Re: Lower QC = Future sale

@SA_penguin, your comments are bang on target. My parents are still happy with their 15 yr old CRT that is running without complain while the LED that i bought 5 yrs ago is asking for yearly maintenace. The adage "old is gold" i think is also true for electronics.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
