Digital TVs - how much power do they use?

^^ Could also be an old school TV repairer, whose business is suffering because parts for modern TVs are obsolete before they've even left the factory. Most of the anti-LCD TV talk i've heard has come from these.

Back in the day there was a network of these guys, all sharing information about common faults on TVs and VCRs, these days they're few and far between and most of the new stuff just can't be fixed, unless it's a generic part that's gone.

Strider, you might be interested to know that there are still TV repairers sharing info with each other but nowadays they're on internet forums rather than reading Television magazine.

Quite a few faults with modern TV's are easily fixed if you know what you are looking for and some people make a living by fixing up and selling TV's that others thought were worthless.

I can see how much ours take through our smart meter. Our 42" plasma panny takes about 110 watts and the 32 inch Sony with led backlight takes about 40 watts. Both of them less than that of the old school tech.

My 42" LCD uses around 55w - 60w going from standby to full on.
Standby is around 1w.

Thanks for the replies! The engineer is someone that a neighbour uses because "he's so reasonable" and I spoke to him when I went round there. She does get a bit carried away if something/someone seems cheap (we all like a bargain but I suspect that sometimes she forgets about quality).

This, sort of, suggests she calls him out regularly. Does she have a CRT TV? If so, it sounds like it's on its last legs and he's trying to persuade her not to replace it. :rotfl:

That was part of what I did ..and video recorders. Repaired customers CRT TVs and video recorders as well. Finished doing the job about 15 years ago but still get all sentimental when I read about televisions and video recorders.

22 years with Radio Rentals and 10 years self-employed.

There will be a label on the TV saying how many watts it uses. If not look in the handbook.

Power ratings on products are maximums provided to prevent the overloading of sockets. Many products use much less than these ratings in normal use.

Newer product manuals may show power use when working to a set standard.

From memory my 21" crt set used about 55 watts and my current led uses about 30 watts, although I have reduced the eco something?.

Back in the day it wasn't uncommon for larger (28" and above) CRT sets to pull in the region of 250 - 300W, a modern day 40" LCD will just about pull 50W when in use.

Your totally OTT and way, way off the mark.

I declare that you are the closest of everyone in this thread.

I was intrigued when I saw this thread some days back and wondered what my Sony Trinitron 28" CRT uses so I decided to get out my plug in monitor to test it. This Sony TV was made in the UK which just shows it's age and it's a very nice TV which has served well and I do not want any crappy LCD/LED TV's. The power monitor I would say reads a little on the high side as I use it to test my PC usage and the figure it shows for standby power is very slightly higher than it should be by about 1 Watt.

The TV power usage varies depending upon the picture displayed, white screens use the most power, black the least. General usage showed................only 65-70 watts!!!!!! with the sound off and about 71-76 watts with it on, volume up but it was getting late so I had to keep it down so full power is likely to rise a bit more. There are certainly some speakers on my Sony TV and none of the crap stuff like modern TV's. They are nice big speakers with lots of Bass and volume and there are four of them plus connections for surround using Dolby Pro Logic. Standby power was 3 watts.

Therefore a big surprise to me as I thought it would use quite a bit more than that. I expected a little above 100 watts. There is no power usage information on the back of the TV.

Modern flatscreen TVs actually use only a fraction of the power used by an old CRT (Cathode Ray Tube) TV. Plasma TVs use more electricity than the LED/LCD variety which is just another reason why Plasmas are being discontinued.

I've got a 42 inch plasma in my living room - should I be thinking about changing to an LCD before it breaks down or get as much use as I can from it & get the an more enery efficient & cheaper (they seem to get cheaper all the time) LCD?
