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...
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.
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.
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.
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.
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.
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.
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.
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.
