Query: Very Disappointing Quality - stay away from this one!

After 6 months the power supply failed and the TV will not power up normally. If you hold the power button in for 1 minute it may 'reset' and power up, but not always. So, I have a TV that works only when it wants to. It does have a nice picture, but that's not exactly useful if it doesn't power on. I am currently working with Toshiba to get it fixed under warranty. I have seen this complaint from other customers, so it does not appear to be an unusal problem. I would guess there is a systematic quality/design issue with the power supply.
