Toshiba 26AV502R Best Buy

Purchase the Toshiba for dual use as a desk top computer monitor and television. The unit has a good picture although the overall sound quality is below average. Offers good value and features for the money. Do not know yet if this is a re-occurring problem but have noticed on two occasions when the set is initially powered up the unit seems to lock up without ever having a picture or sound. Had to unplug the unit and power up then seems to work as designed.
