My Memorex under the cabinet tv failed, model MVUC821. The problem with the unit is that the tv does not come on, picture or sound. When the power button is pressed, the unit goes from standby mode (red light on) to on (red light off and blue light on) and the built in dvd drive makes a sound from a periodic motion it makes. Unplugging the power cable to the dvd drive naturally stops the dvd activity but the unit does not continue by turning on the tv. I was told that my power supply most likely failed and that this might be confirmed by examining the electrolytic capacitors to see if any has swelled. If so, they should be replaced. I examined the unit and replied to the `expert' that the power supply for the unit is separate and that all the electrolytic capacitors on the pc boards appear to be fine. I had also measured the voltage from plug-in wall power supply under load and no load and measured 12 dc volts which was the labeled voltage on the power supply. Your thoughts? att80
