When I reviewed the Toshiba SV670U series nearly two months ago, the review was based on the second of two review samples.Why the need for a second sample T1 suffered from a pretty glaring problem in my opinion.In certain scenes, parts of the local dimming LED backlight would flash intermittently and at random.The instance we noticed first was during the demonstration sequence from Digital Video Essentials: HD Basics (around the 2:50 mark).
Toshiba Tv Firmware S Series Nearly TwoWhen the computer-generated plants fade in from black, flashes appeared in the lower left and upper left of the black background as the overall brightness of the scene increased. When watching Austin Stevens, Snakemaster on Discovery HD Theater, we saw brighter flashes, akin to blooming, in the darkness around Austins head as he leaned toward the light in a cave. During Watchmen the flashes also appeared occasionally and for no reason we could discern. In the initial fight, for example, the lower-left corner flashed briefly just as the Comedians blood drips down onto the smiley-face pin. A zoom in to President Nixon created another flash in the lower right. Our guess is that LED elements were lighting when theyre not supposed to. When we talked to Toshiba about what we saw, the company insisted on sending T2, which didnt suffer from the flashing issue. Toshiba Tv Firmware S Update The SituationWe mentioned the problem with T1 in the review, telling readers wed update the situation when we knew more. Now we do. Toshibas reps identified the problem as a firmware issue. To address this potential problem, Toshiba has made a firmware update available. As the companys rep put it: Based on our current consumer and reviewer feedback, this has not been an issue. However, in our ongoing effort to provide the best possible product, we will provide the update for units with the original firmware. Toshiba Tv Firmware S Upgrade Works AsI tested the new firmware by updating T1, and the upgrade works as advertised, removing the flashes and restoring picture quality to the same level I saw on T2. If youre an early owner of a Toshiba SV670U series, you might want to do the same thing. Toshiba doesnt have an online firmware upgrade feature like Samsung and Sony, however. Unfortunately you have to call the companys customer service department (800-631-3811) and request to be sent the upgrade; just ask for the latest firmware for your TV. It will arrive on a USB stick, and when you follow the instructions--which took about two minutes in our experience--your SV670U will have the update.
