Why is the t-con board in my Toshiba Reza 42HL67 LCD TV repeatedly dying?

Could be just bad luck! It seems unlikely to me that the power supply would take nearly a year to destroy the T-con board!
You could get in touch with Toshiba to see if there is some kind of problem that is cropping up on this model that might cause failure in on the T-con.

Dvd sometimes work and most time flicker

I suggest you call Bose. Most likely your disk drive needs to be fixed or replaced. In rare cases just updating the system with the latest software will help. Anyhow call Bose, they will fix it.

Model RTD325W My DVD player has been locking up during a movie and even when I am listening to just the radio (tuner mode) I am forced to unplug to reset since it will not allow me to power off with...

Fastest way to check this is to disconnect all speaker wires from the unit leaving the video hooked up and play a disc. If it keeps playing fine, you have a speaker or wire problem. If it still reacts the same, it's an internal problem and would need to be serviced. If the unit continues to play, post a reply and I will describe in detail how to troubleshoot the system. Hope this helps

If you are not seeing the power light, than that can mean two things:

No power to player!?

Open it up and check the main fuse. It is located on the board where the wall plug enters the chassis.
