This video shows the value of understanding how some of the shutdown and
feedback circuits work in an LCD computer monitor and or LCD TV since
many of the same principles apply. It also shows me demonstrating the
value of using hold back lights to help you determine if your inverter
board is working correctly. If your a professional looking for more
understanding on how to repair LCD TVs or an electronics hobbyist here
are some great resources.
How to troubleshoot and repair switch mode power supplies by Jestine Yong at http://davestv.jestinemichellepow.cli...
This book is a bit spendy and unless you do this as a profession it's
probably hard for most people to understand why anyone would pay so much
for an ebook. Nevertheless since TV repair is my business I can
honestly say this is the most helpful book on power supplies I have ever
read. In my opinion it's a must read. Jestine is good at getting right
to the main points you need to understand about troubleshooting this
kind of power supply and its associated feedback circuits. Since a
majority of the problems I have seen on LCD TVs are related to bad power
supplies I figured it will pay for itself many times over. Most of the
book was easy reading with plenty of pictures and diagrams. ======================================== Testing electronic components and finding unknown resistor values by Jestine Yong. http://5d8388ioop4nfm862d1b0u7sbj.hop... This
is an excellent book for A beginner level student who wants to learn
how to test electronic components like a professional. Jestine really
took the time to make this book easy to understand. ======================================== How to repair LCD Computer Monitors by Jestine Yong at http://davestv.jestinewilliamlcd.clic... Even
though this book was about computer monitor repair I found most of the
troubleshooting techniques he demonstrates also applied to LCD TV repair
so I was glad to have read it. Much like the book on Switch Mode Power
Supplies it was easy to read and has lots of pictures and good
troubleshooting techniques. ======================================== Mikes TV case histories The latest paperback edition has hundreds of case histories on LCD, CRT, Plasma and Projection TVs. at http://www.mikestvtips.com/ 1-410-272-4984 When
I first started in the TV repair business and my troubleshooting skills
were not that great often times Mike's case histories told me exactly
which parts I needed to replace and it often saved me from having to
purchase a great many schematics. I have been using his case histories
since 1995 and I would not be with out them. If you call him please be
considerate of his time zone and call between 11:00 AM TO 8:PM Eastern
time only. ======================================== Getting Started In Electronics by Forest Mims available at some Radio Shacks or through this link. http://www.Forrestmims.com If
you know nothing at all about electronics and want to start with the
basics this is a fantastic book to start with. This book is packed with
pictures.
Last
month I finally got round to replacing my 6 year old Sony LCD TV with a
new Smart TV. I picked up a Samsung 8 Series Smart TV, the catchy
titled UE55ES8000. The TV is a 55" LED Smart TV and has all the expected
features of a Smart TV including apps, 3D and a Freeview HD tuner. Here
is my video review of the TV.
I am using the TV connected up to
my Sky+ box, Media Center PC and my Xbox all of which I connected up via
HDMI , as the TV has three HDMI ports I could bin my old HDMI switcher
which was causing me a lot of grief. The picture quality is absolutely
fantastic, the colours are very rich and I could really see a difference
in the refresh rate over the old Sony TV.
With the TV you get
two remotes, one of them the traditional style remote and the other
designed to control the smart TV features as it has a touch pad on it.
You can control the TV with only your hands as it has Kinect style hand
control which works surprisingly well but for me you can't beat using a
traditional remote control. Voice commands are also available but to be
honest I am happy sticking to the standard remote.
Also with the
TV you get two pairs of Active Bluetooth 3D glasses, movies play very
well in 3D and look great. I must admit I am not that big a fan of
wearing 3D glasses while watching TV but for a quality movie its worth
it, the TV does have a 3D mode that will convert 2D content to 3D which
kind of works ok but it's no substitution for true 3D content.
Samsung
have an app store as part of the Smart TV features. There is BBC
iPlayer, ITV Player, Netflix, LoveFilm and lots of other apps including
Skype, BBC News and social apps. One thing I have noticed is that many
of the things I use my HTPC for are taken care of by the TV apps. So the
Smart TV is certainly reducing the need for a PC connected to the TV
but that is probably worth a post in its own right. There is a camera
built in to the TV which can used for taking photos from the TV (not
exactly sure why you would want to do that) and for Skype.
Also
built in to the TV is a DLNA/UPNP client (Samsung AllShare), I was able
to take pictures on my Nexus 4 and send them straight to the TV using
Twonky Beam. You can also pull content from a DLNA server, I had no
problem browsing my servers and watching videos stored on a Windows
machine on the TV. You could also plug a USB drive into the TV and watch
it without needing a PC.
While I was at CES last month Samsung
announced the Series 9 range of LED TVs which have a new UI, fortunately
Samsung will be releasing an Evolution kit bringing the 9 series
features to the 8 series. There are no price details yet but it's good
to know the newly purchased TV is not completed out of date.
So here is my video review of the Samsung Series 8 55" TV (UE55ES8000)
