My sony 39 inch plasma flat sceen is more then 18 months old and the sound quality has always been poor. The volumn must be raised over 60% before it becomes clearly audiable. Numerious people young and old agree the sound is poor. Do you have an answer to tohis problem?

We have the same trouble! It is the power transformer. These models had faulty ones. Can you believe that this is the 2nd time we have had this problem? And our Beautiful RCA XBOX Entertainment Series TV's that is only 6 years old and there cousins all have these problems!!!! Our repairman (and good friend) told us that it would cost about $250 to fix. Of course he didn't recommend us doing this because the TV TUBES in these series are also very weak. He says that these Large Screen RCA TV's do not make it much past 5 to 7 years. So if you spend the money to have it fixed you will most likely be wasting your time and your money! Sure it will work for another year, but that is about all! It is far better do what we are doing and go out and buy a new TV. Our Repairman Friend spend a lot of time researching new Flat Screen TV's for good quality and longevity. He states that we all should look at buying a good solid brand like Panasonic if you are going with a 32 inch TV or smaller. A Sharp if you are going larger then 32 inch. Far Better Quality on these TV's and a lot longer life! He states that the other cheap ones that we see out there today already are having a lot of problems! You get what you pay for! These cheaper so-called bargains will have lots more problems in the months ahead and most will more then likely stop working all together in 2 to 4 years. So buyers beware of these great TV prices on these cheaper models! PLEASE do your homework and please listen to us and our repairman and you will not end up screwed like we were! Now we are stuck with an old RCA clunker which warranty expired after the first fix which was not done correctly! They came out and put a little solder and adjusted the Transformer instead of replacing. It was just enough to last another 6 months for the warranty to expire! Shame on you RCA! We then went out and bought one of these cheaper models and found that the quality is terrible! It already has problems and we are fighting to get them to honor the Warranty! Did I mention buyer beware? Something that looks and sounds too good to be true usually always is! Sorry for the long response! I just hope thise helps others!
I don't have the table for decoding the flash sequence but I suspect it points to the main power supply.
Even if the repair costs a few bucks, have it repaired and if you don't have a digital to analog converter yet through the famous (infamous?) coupon program, get one and even when you upgrade to a wonderful flat panel set, don't dispose of those; park them in a dry place so you have something to watch while the flat panel is repaired.
The track record of these, off- and name brands, is looking pretty poor.
They will fail much earlier than your Sony did.
You can verify this right here at FixYa by searching on LCD, flat panel, plasma, etc.
Sony doesn't want anyone to see a poor picture on a Sony tv so they have a circuit that blanks the video if there is a weak picture or any other problem concerning picture quality. My Sony factory Instructor told me this many many years ago. I'm feeling old...but anyway you need a technician. Sorry.
I posted originally about a year and a half ago about this very same problem. It is a known defect with the WEGAs that Sony refuses to do anything about. Here's the thread with my experience - the upshot is, try doing a "hard reboot" by unplugging it and leaving it unplugged overnight. That worked for me for about 18 months, but no longer...I'm replacing my 5 year old WEGA today (NOT with a Sony).
