A Common Problem With All Plasma Tv Sets
82No Picture Plasma Tv Set.
No Picture On Your Plasma Tv Set
Ok lets start ever wonder why your plasma tv set has no picture or why one night you were watching your tv set and then come in the morning to turn it on with no picture but sound.Well my friend i am here to tell you that this is a common problem with plasma tv sets, it is not the brand of the tv set or who build the tv set it is just bound to happen with time. The sad part about it is that some of the manufacturers know this but the name of the game is to make money, cant be mad with that i would like to make a little bit more money other than my fulltime job, but hey thats another subject.Moreover what can be causing this problem or why does this happen.Instead of boring you with a long article i am going to get right to the point and what is it that you can do yourself to fix it yourself.Ok this problem is coming from your Y sustain board which works with the Z sustain board to create the picture, it works just like the old tv sets with the vertical and horizontal deflection circuits.The reason that this happens is very simple after to much hours of usage by you the circuit board is like anything else (like us getting old) gets old and some of the components are not functioning like they are supposed to most of the time it is the fet transistors in that circuit that go bad and have to be replaced.Another problem that can cause this would be the tv set being programmed to a specific hour usage, this just means in simple english that if your tv set was programmed to be used for lets just say 40,000 hours before something goes bad or faulty, then that is just the way the people builded that tv set, less likely but it does happen.By this time you are probably asking yourself what can i do about this problem to fix it myself, well the first thing is to be very careful when doing it yourself, second is to aquire the service manual for your tv set from either fixya.com or eserviceinfo.com, third is to contact the manufacturer of the tv set and get the repair kit that they have for your tv set which consist of the Y sustain board the Zsustain board and the X sustain board or logic board.Once you have all this now you can do it yourself by following the instructrions on the service manual, remember to be careful and have the tv set unplugged from the wall before you service it, you should be able to change out the boards by yourself.Change the boards out and your tv set should be up and working normal again,have fun while you are doing it but be safe and save money on the repair cost.Hope this article helps whoever needs help and Thank You very much for reading.

Please get a copy editor: I was too distracted by the poor writing style to fully understand the article.
Thank you for this information! After 13 months of ownership (just past the warranty expiration) my LG Plasma TV developed a serious problem. These include picture degradation, shutting down at random, screen lines, color degradation and others. We systematically applied solutions such as switching cable locations, using different cables, trying a variety of power supplies (basic strips to battery backup) and nothing seemed to help. We observed the TV in different modes and kept having the same problems whether we were using the Set Top Box (cable), the DVD player or the gaming system. One observation stuck out form the rest – the problem did not occur when we were watching a black and white movie. But as soon as the film ended and we switched to a color movie, the screen popped and went blank.
I started researching the issue on-line (thank you Google!) and after some trial and error with search terms eventually discovered other plasma television owners with similar problems – some have been kind enough to post pictures and videos that allow me to see the same problems as my plasma TV. Further investigation revealed that a common culprit appears to be the Y and Z Sustain Boards. These circuit boards are akin to the vertical and horizontal deflection circuits of older televisions and are at the heart of creating a picture on the screen.
Unfortunately, the Y and Z Sustain Boards (more simply called the YSUS and the ZSUS) are a serious weak point in ALL plasma televisions. Do a Google search for problems with plasma televisions or problems with these boards and your search results will light up with hits! Information about problems with these components span years of plasma manufacturing and cover a wide variety of brand names. The worst offender seems to be LG – especially since they manufacture these boards as components for many other brands and have been doing so for many years.
Doubly unfortunate is that this problem seems to be rampant in the plasma television industry yet no one seems to know about it. It does not seem to be a safety issue (no fire hazard, etc.) so the Consumer Product Safety Commission has no information on it, it is a standard component of larger items with no particular brand involved, so the Better Business Bureau has no records on it, and the issue is spread out and technical enough that the average consumer seems to be unaware that it is such a large issue. How many plasma TV owners have to have this problem before it becomes general consumer knowledge?
In other words – this is a KNOWN ISSUE with plasma televisions yet it has somehow fallen through the cracks of consumer knowledge and the plasma manufacturing industry is certainly not be\ringing to anyone’s attention.
A call to LG customer support was less than helpful. The customer service representative on the other end of the line had no information on this issue (even though it is quite common). I knew more about the inner workings of my television than he did. The LG warranty does cover the “Panel” for a two year period – and these components would appear to be core to the “Panel” – but the service rep I spoke with could not provide me a definition of what is included as part of the “Panel”.
To put this in perspective, my family once owned a Sony Trinitron for nearly 20 years before it was replaced and our former primary television (still in service) is a nearly decade old Sharp CRT unit. Neither of these units developed the problem this LG Plasma is having and neither ever needed to sort of repairs (both dollar and labor wise) that this plasma unit needs. So yeah – this is big deal. When I spend the kind of money necessary to purchase a product such as a television, I expect to get more than 13 months of service out of it. I intend to get this unit repaired or replaced and I do not intend to be the one paying for it!
Thank you very much for all the comments.Glad i was able to help someone.
Well the article sort of speaks about TV's that are bound to break down over time, which is quite understandable. But I am sitting down here with a Samsung PDP43D490 which is a mere 27 days old as of today with the same problem. The only difference is there is neither sound nor video. It just sits with a deep black screen and doesn't even turn itself off with the remote. I am super pissed off with Samsung now.
