your a professional looking for more understanding on how repair LCD
TVs or an electronics hobbyist here are some great resources. Troubleshooting & Repairing LCD TVs by John Preher at http://davestv.jptv97501lcd.click2sel... For
someone new to electronics the first few pages of this book may be a
bit challenging but the majority of this book is easy reading with lots
of pictures,diagrams and useful troubleshooting techniques. Johns book
gives you a good idea about the main test points you should look for and
their approximate voltages. ======================================== How to troubleshoot and repair Switch Mode Power supplies by Jestine Yong at http://davestv.jestinemichellepow.cli...
This book is a bit spendy but I'm still glad I purchased it. 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... I

troubleshooting. ======================================== 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 similar to Johns Prehers book on LCD
repair but in Jestines own style. It had lots of pictures and good
troubleshooting techniques. ======================================== Mikes TV case histories The latest paperback edition has 1300 case histories on LCD, CRT, Plasma and Projection TVs. at http://www.mikestvtips.com/ 1-410-272-4984 When

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

which parts he replaced to get them going. I found this ebook was
helpful in better understanding the connection between certain symptoms
and their causes. Right now it's only 10 dollars. ======================================== Getting Started In Electronics by Forest Mims available at some Radio Shacks or through this link. http://www.Forrestmims.com If

Many
times bad capacitors can be momentarily restored to their normal
capacity with the use of heat. This will not work if your capacitor is
internally shorted or to dried out.. My demonstration is not meant to
encourage the use of a hair dryer in place of a good capacitor tester
but it can be helpful in doing a quick estimate.

In this video I show the importance of measuring the current or the
power your TV is using as a way of determining if there are any shorted
parts. I also show the value of using a variac transformer to find
shorted circuits before you apply full power.

When
I first started out doing TV repair I never realized buying original
parts was so important in many cases. I'm not against using generic
parts as long as they work correctly but after a friend of mine was
forced to redo three convergence jobs on his customers big screen TVs I
thought the potential for problems was worth mentioning.

I remember being told that the Cold Cathode Fluorescent Lamps on LCD TV's will draw more current as they begin to age due to a build up of carbon, After replacing a burnt out inverter transformer with a new one, I used my temperature probe on each of the 4 output transformers to see if my replacement transformer was operating at a higher temperature than the others, and i noticed it was. My first thought was there might have been an issue with the replacement transformer, so I tried swapping locations with one of the other transformers, but it still ran hot. My youtube friend Norcal715 suggested there might be an issue with AC ripple distorting the drive pulse going to the transformer due a bad electrolytic capacitor, but. when I examined the transformer inputs I noticed they all shared the same source, so this ruled out there being a bad capacitor on the input side, I also checked my ceramic capacitors on the outside and they all checked okay, and this led me to the conclusion that my Cold Cathode Fluorescent Lamps were starting to draw more current than they should due to a carbon build up from natural aging.The TV I repaired is a Samsung Model LN40B550K1F. The inverter board number is a BN44-00264B. The transformer part number is QGAH02095.
We are going to be giving a general overview of LCD TV Repair in this video and we are going to be taking a look at the different components in LCD TVs and what can go wrong with the components and the symptoms they will show and how to diagnose the problems and how to get them fixed.If you are having a problem with your TV please comment below this video or send us a YouTube message with your TV model number.Before beginning work, be sure you have unplugged the TV from any power source and that you are properly grounded.Remove all the screws for the back cover of the TV.Remove the back panel of the TV.Identify different parts of the TV. Power supply takes in and distributes power throughout the TV.Main board typically manages all inputs and outputs for your video and sound.Backlight Inverter controls your CCFLs and the light source for the TV.T-con board connects the video from the main board to the panel through the LVDS cable.Not every TV is the exact same.There are two different levels of TV repair, component level repair and board replacement repair.The first thing that could go wrong with the power supply is that the TV will not turn on. Be sure your outlet works and then begin to diagnose the issue and either check components or replace your power supply board.Some common problems on these power supply boards are bad capacitors with bulgy caps or leaking fluid.The first sign that the main board could have a problem is if you do not have an image on the screen. Be sure your source video is working correctly. Either replace the problem components on the board or replace the entire board.The t-con board could show a problem symptom if you are able to hear the show on your screen, but you cannot see the image, there is most likely a problem with your t-con board. The t-con is also known for causing vertical colored lines or half of your screen not having an image.Backlight inverter problem symptoms turn on the TV and the image only shows for a second and then the image goes black, or if you have a flickering image on your screen it could be the backlight inverter that is causing this problem.
