Since I'm a newbie here, I'll follow the AVSForum 9th Commandment and give my thoughts on the Panasonic TC-L32S1, which we owned until relieved of it by a burglar this past Tuesday!
The reason I joined the forum was to research alternatives for a replacement, so it's obvious I wasn't totally satisfied with the set. On the other hand, I doubt any of them is perfect, and it was our first non-CRT television so I have little to compare it with.
The original decision to go with the TC-L32S1 was influenced by positive experience with Panasonic TVs in the past and with Panasonic products in general (don't get me started on Sony). Being located in a small town I was not able to view the TV prior to purchase (mail order), but I did decide from viewing other sets that 1080p was worthwhile even for a 32-inch screen, and the Panasonic models I was able to view in the stores looked better to my eye than the competition (including the Samsungs), although who knows how they were set up. Also, I was less than impressed with off-axis viewing of my father's 32-inch Samsung LCD (one of their better units), although he's been very happy with it.
So, as for the Panasonic TC-L32S1, I can say that it did in fact have a very nice picture, better than other 32-inch LCD sets that I have seen (bearing in mind my limited experience). Off-axis viewing was excellent, with no noticeable change/compromise in the picture when sitting at different locations in our living room. It also worked seamlessly with our DVD player, an upper-end Panasonic unit from a couple of years ago; it seemed particularly good at "stretching" older video to the wide-screen format without it being noticeable, which is critical for us since we only watch DVDs (many old movies and TV shows) and don't have/watch broadcast/cable television. Build quality (as with most Panasonic products I have owned) was very good.
However, I can confirm that the audio volume was much lower than expected and in fact weaker than any other set I can remember, and with some DVDs we could not get adequate sound levels even with the volume setting at maximum; ultimately, we resolved the problem by connecting it to a pair of old AR PoweredPartner external speakers. It was also very difficult to pick out details in shadows and dark scenes (e.g., night scenes in old crime movies), although frankly I have not seen better with other sets so perhaps it's inherent with LCD TVs in general. Incidentally, we are limited to 32-inch sets by the size of the cabinet that we put the TV in, so I have never considered plasma and high-end LCD TVs that are not available in that size.
I am strictly a layman when it comes to TVs, so please take these comments with a grain of salt. Nevertheless, I hope that folks here might find some of these observations useful. Also, I'd be interested in any thoughts or suggestions others may have, since I am currently trying to decide whether to replace our TV with another TC-L32S1 or with something else, like maybe going out on a limb with a 32-inch Sharp 700UN.
