Summary: I have had the same vertical lines issue with a Regza model 52HL167 but am fortunate since it's taken over 36 months to show up. I say fortunate because this is a well known issue with 52" Regza's from the 2008 year models (looks like the same with the 40" and 46" as well) and sometimes this begins to show up as early as 18 months. There are stories/angry customers all over the internet, just Google the issue.
Summary: I bought two 40" REGZA's at the same time. One is used heavily and is ok. The other, used very, very little, has developed the streaks. It is two years old and the local TV Expert/Repairman asked, "Did you buy a warranty?" Of course I didn't. He said, "You are out of luck. The display is bad, Toshiba doesn't care, and it will cost as much as a new set to get another display.
Summary: After about a month the sound started acting up. We thought nothing of it all I had to do was change source and all was good. We are getting a new sound system so that won't be a issue soon. I love the picture. The only other think is that it has a very shiny face and well if u are like me and have kids well I have to clean it every other day or so cause of finger prints. But still love the tv.
Summary: This set has a faulty sound board. There are no replacement parts in the pipeline. If you get one that has the bad board you wont get any support from Toshiba. Buyer Beware! Made claim in Sept. on the phone with CS as I type, betting I will get another brushoff. Never had such bad support for a product. Can't express my frustration explicitly, enough!
Summary: I purchased one of these TVs from a large web retailer back in December 2010. We were quite pleased with the picture quality up until February 16 2011, when the screen went black and did not return. The Toshiba tech folks were civil but not helpful - there's just not much that can be done when one of these goes out. The TV is at a Toshiba warranty shop now, getting out who knows when. Caveat emptor.
Summary: only sound was average. Since I wanted it as part of an in place sound system the TV sound is not used, but heard through the present speakers and receiver. This works out very well. This is my second Toshiba TV in less than 4 yrs. The first was excellent, but technological developments in the intervening years has made this a worthwhile investment. The picture itself is definitely a large improvement.
Summary: This television was on display at several Best Buy Magnolia Rooms. The set was out performing Panasonic and other LED's and plasma's including Samsung and Sharp in the same category as well as units in higher categories. The LG and Sony efforts didn't even come close. It was our opinion that some of the 4 and 6,000,000 to 1 contrast ratio sets were also not providing as good of video quality.
Summary: I waited about 10 months to post my opinion of this TV. Like some other folks here, I bought it at 6th Avenue Electronics. I went into the store with cash for a similar, but much more expensive Sony unit. The sales person told me to first look at some Pannasonic plasma they had on sale, which I didn't think looked great, and then he showed me this TV. It was sitting in a row of Samsung and Sony TVs, and out of the 10 or so in the row, this TV clearly looked the best.
Summary: This HDTV fit my needs perfectly and at a super price point. It's not the slimmest but that was not a issue for me. 240 Hz and LED back-lighting sold me. It has all the inputs and outputs you need.
