Why You Need to Join Paid Membership Training Sites If You Want To Learn Projection TV Repair

August 16th, 2009 DIY guy No comments

Looking for projection tv repair tutorials on the internet is not an easy thing. More often than not, focused tutorials on repairing a particular electronic unit will be very hard to find and if ever found, will not be as complete as you would prefer it to be. They will probably be in bits and pieces and scattered all over the internet which you will still definitely need to search for and piece together somehow.

This is the reason why being able to find a forum that specializes on the type of information you are particularly searching for on a specific electronic item may be considered a lucky thing since these sites will usually have a lot of data about your particular interest— this being that they are a site focused on a subject. The only problem with them is that most of them may require payment in exchange for the membership.

Paying for it isn’t necessarily bad especially if it goes to paying for the webmaster’s efforts on making his/her forum really functional for its members. Joining fees are there to make sure that help sites like them will continue helping people out in their search for information.

I am currently a member of such sites to help me in quest to learn LCD and plasma TV repair. Most of them ask for a one-time payment in exchange for lifetime access to their database which contain tons useful information. The reasons why I like these sites are further enumerated below:

1. Some pay sites that offer, say, plasma and LCD TV repair training information have one-time membership fees which I think are cool because you will also have access to future database additions without incurring additional charges. The site owners usually promise to regularly update the information contained in their sites and allow access to all members at no extra cost.

2. These pay-sites have spent a lot of time and resources gathering the things you need like the training and service manuals, schematic diagrams, step-by-step how-to guides that make life a whole lot easier. Basically almost everything you need are there ready for you to download and digest. Imagine how much time will be saved when you choose this route as opposed to going the free-to-join sites that waste a lot of time and effort (scouring search engine result pages).

3. In terms of cost, you save a lot more money not only in terms of time but actual money. There are some sites that offer pay-per-download service which are not necessarily training membership sites. Each manual cost around $10 up.

Sites that offer one-time fees just give out those repair manuals virtually for free. Those that ask for 50 dollar membership fee typically has at least 400++ manuals that are ready for downloading anytime. Since no per manual fees are asked, considering the $50 joining fee, each manual will come down to just 13 cents per copy. This kind of a deal is ideal for anyone who wish to make a career out of electronics repair!

4. Studying how to repair electronics through online electronics repair forums and training sites have the advantage of affording a lot of convenience for the recipient because you can study anytime and anywhere you may be. Most people will love the convenience of learning right inside their homes or offices instead of going out to real schools with real classrooms.

5. The speed at which technology is developing can become very profitable for those who provide related services to them such as electronics repair, assuming, of course, that they are able to keep up. Online repair courses such as plasma and LCD TV repair courses give them some fighting chance by providing the needed information bring them up to date. These training sites are a boon to the electronics servicing field.

If you have been keeping tabs of current events in the flat screen TV industry, you probably know that it has been going through some pretty huge demand surges that only support the hypothesis that the TV repair industry is still in bloom. Take heed of this huge potential money-maker by training yourself and your crew on how to repair new electronics like LCD and plasma TVs and other flat screen televisions that are coming out so that you won’t get left behind. Watch out for an influx of plasma and LCD TV repair owners begging you to fix their televisions!

There are a ton of reasons why you could be having technical problems with your LCD flat screen TV. The important thing to remember is that these contraptions are microprocessor based, much like your laptop or your desktop PC. That means that at the first sign of abnormal function or operation you should do exactly as you do with your PC: Reboot!

If your LCD television is being non-responsive, switch it off properly (with the power button), count to 10, unplug it from the wall socket, then after about 60 seconds, plug it back into the power socket and turn the TV back on again. With a lot of luck, your TV is now back to normal!

The next possible cause of problems that you should look into when experiencing problems is the High-Definition Multimedia Interface (HDMI) connection. HDMI is a great way to get high definition video fidelity, but it is so good that the content providers were worried their stuff would end up out on the internet, easy to copy and distribute. To prevent such piracy, they created this copy protection plan called High Density Copy Protection (HDCP); which is much like an electronic data handshake system wherein the source and display devices (the televisions) have to recognize each other and agree that it is okay to send video. If there is no handshake, or the process gets corrupted in some way, then there you go: No video. This problem, although revalent in the younger days of HDMI, has been steadily improving in very recent years due to better technology.

If you are having LCD TV problems, there is a chance that it may be an HDMI related issue. Here are some of the problems you might encounter and what you need to do:

Problem #1: No Picture

If there’s absolutely nothing on the screen then shut the television down and then restart it. Make sure all the connections are properly placed and where they should be. Look at the screen. If you see a resolution notice or indication then chances are that the Display Data Channel (DDC) line has communicated between source and sink. This means that the problem is likely video related.

Problem #2: No Audio, Flashes, Pink Screen

If there is no audio output accompanied by a pink screen, it might be a DDC communication error or problem. To diagnose this, turn the system on while all the HDMI cables are plugged and properly connected. When possible, try using shorter cables. If the system still fails to come on when you power up, try using different inputs. You might find that your cable box will work but your DVD may not or vice versa. This can happen because of stray capacitance on the DDC line inside the HDMI cable. This may actually be hardware related. Try getting a DDC line conditioner. These types of problems completely go away after conditioning.

Problem #3: Sparkles on the screen/picture

This is usually data transmission-related problem. Data transmission problems with HDMI are usually cable-related. There is a possibility that the cable is underperforming due to excessive length. This is especially common problem with cheap, sub-standard cables. Remember the HDMI specification indicates that the cable length should not be more than 10 meters. Shortening the cable should improve the signal integrity. Another possible scenario in this situation is a bad connector. HDMI connectors are famous for this very common.Try a new cable at each position along the signal path.

Problem #4: Picture on the Screen Comes On, Then Goes Off

This is usually caused by a couple of things. First is when one or more of the video Transition Minimized Differential Signaling (TMDS) channels has a high bit error rate or is not working at all. Second is when the DDC line does not quite make it. In that case, the High-Bandwidth Digital Content Protection (HDCP) is not getting a new refresh key. Buy a better quality cable with larger wires. When it comes to wire gauge, smaller gauge equals bigger wire diameter. Hence 20 gauge is larger in diameter than 24 gauge.

If you are having some LCD TV issues, check these things before you call the expensive TV repair guys. In many cases you can easily repair LCD TV yourself without spending a fortune.
