The great thing about this new resource is that it focuses on a very common problem with modern flat screen TVs that use LCD panel screens (basically a vast majority of big/flat screen in homes today).

We’ve had plenty of posts on this site discussing LCD TVs with failing screens and which stops producing images or pictures. It is aptly dubbed as the BSOD or the Black Screen of Death and usually strikes fear in many TV owners. We’ve also posted on other screen issues like image distortions, having horizontal/vertical lines, etc. The good news is that these problems are relatively easier to troubleshoot and repair and a huge fraction of the cases are caused by faulty T-Con boards which is one of the controllers that make the LCD panel work as they should. (Note: T-Con stands for Timing Control or Timing Controller).

So Kent Liew came out with a comprehensive technical guide on how to fix LCD TVs in the context of malfunctioning LCD screens and the controller boards (specifically the T-Con). He posits the common occurrence of these TV components going bad and the great opportunity for many DIY, or even professional repairers to learn how to fix them properly as good enough reasons to avail of this training resource.

Also, while he admits that most suggested fix for faulty T-Con boards is to simply replace the entire board due to their relatively inexpensiveness, he does point out that not all T-Con boards are inexpensive and that it may not be the case for high-end TV models. It is also a good idea to properly identify what exactly is the problem with any T-Con boards by properly diagnosing them as that will add credibility to your technical know-how insofar as customers are concerned (especially for professional TV specialists, repairers, etc.).
