Check the 24vdc output, look at the screen in darkened room to see if you can see the backlight is working or not, if it does then you may have T-CON board problem or it is not getting the VCCC_PANEL from the main board.

I have a memorex. I am getting sound but no picture. When powered on, the memorex sign shows up but then no picture just sound. Also makes a slight screeching sound for approx 10 sec. when powered on.


I guess the blanket draped over the TV is intended to give it a "timeout". Anyway, you will likely conclude eventually that the internal power supply has failed.
