Question

Tks for your help. The manual says the power consumption is 150 watts for the TV and 20 watts when using the built-in DVD player. The rewiring I did to make it a monitor was thru the cable of the DVD player after it was frozen in the DVD mode. Now the only thing that functions is the on/off switch and the image to the LCD screen comes directly from my HD cable box through a component cable which I soldered to the DVD input connection on the motherboard. Under this condition would I still be consuming 150 watts or something less perhaps as little as the 20 watts since I wired it thru the DVD input cable. Not an easily answered question I realize but what is your best guess?
