New Tests: 3 New TVs from Sony, Philips, Toshiba

If yesterday's look at the latest generation of LED backlit HD TVs wasn't enough for you, we've got three more regular LCD screens for you today:

• The Sony Bravia S4000 series: these entry-level HD Ready TVs come with digital tuners that only support SD TV, not HD.  There are 26'', 32'' and 37'' versions.

• Philips' new PFL9903H series is a lot more powerful, and features the latest refinement of the Ambilight system, known as Aurea, to project colored light on to the frame as well as the wall behind the screen to match the image on screen.  Two vesions are available: 37'' and 42''.

• Toshiba, meanwhile, has update its Regza range with the new AV565DG series of affordable HD Ready TVs.  Slightly smaller this time, it comes in 32'' and 37'' versions.

With such a range of sizes on offer, these new models are sprinkled in three different Product Surveys: TVs under 29'', 30'' to 39'' and 40'' to 49''.
