Good Picture, Short Bulb Life
We have had the Toshiba 62HM195 for about two years now, and we are on our third bulb. To Toshiba's credit, the first bulb was replaced at no cost to us, since the bulb which came with the television was defective. The next bulb lasted about a year and a half. A replacement bulb ran around $200... I can not imagine they will go down in price from this point on.

When it is working, the picture looks great. We have used it with High-Def cable programming, video game systems, HD-DVDs, and Blu-Ray discs, and it performs well.

pretty good
the main reason I bought this TV was the price. 1080 and 62" for about $2,200. As another reviewer stated, the bulb on my TV exploded about 1 month into use. The customer reps didn't give me much hassle about sending a new one out. I've been using the new bulb for about 6 months now with no problem.
I think the picture is great. I use a HD cable box and upconverting DVD player, both via HDMI cables. I have no problem with either yet.
2 reasons for not having 5 stars is the bulb popping, and the sound is subpar. I know it's expected to use a home reciever, but Toshiba still should have made the sound better then they did. You will have to buy a reciever with this TV. The lack of sound quality will annoy you after a month or two, like it did me.

Third month- Its Great- No problems.
I love it. Cristal clear images with no problems. I have not noticed any fan noise until I am turning off the TV and it is cooling down.

Amazing picture!
My boyfriend and I invested in one of these televisions as an alternative to going to the movie theater, and the picture is even better than at the theater! Colors are extremely vibrant and the image from our HD-upconverting DVD player is extremely sharp and lifelike. I haven't had any of the problems with bulb life and fan noise that other folks have; apparently it was a problem limited to the first run of production. I can't comment on the sound or cable TV viewing, since we use neither of these features, but for sheer picture quality at such a large size I have yet to see a comparable set.

Six month experience with the 62HM195
I experienced tiling or pixelating of my picture from the first day I plugged it in. I thought the problem was with my cable service, but after 5 visits by the cable company and one tv service call, I discovered that I just needed a firmware upgrade. Toshiba sent me a smart digital card with the firmware upgrade and they talked me through installing it. Problem solved.
The TV guide feature that had worked, stopped working after the firmware upgrade. I contacted Toshiba and they are investigating the problem. They have been investigating the problem for over a month now. I have found out from a service representative that they only have one person that deals with all of the TV guide problems. I am waiting for that person to call me with the solution.
In the mean time, the lamp blew. First, I noticed that the picture became dim. I increased the brightness but then I heard a loud crack. That was the bulb exploding. That happened after 3 months of light use. Toshiba sent me a new one and I installed it without difficulty. No TV for a week though while I waited for the new one to arrive.
When changing channels, there is a 3-4 second delay before the channel actually changes. This makes channel surfing VERY slow. I have been going to TV guide online to find my channel line up.
I am happy with the picture in High Definition, HOWEVER, I have never owned a TV that operates with such unreliability and therefore I would not recommend that you buy it.
