Question about Toshiba TN61X81 61" Rear Projection Television
I can hear the sound of the channels, but there is no image
I had the same problem with my sis tv. You have to open the front grill and see if the filament on the neck of the crts is lit. If it not you may want to check the horizontal ouput transistor(Q416- for open or short) and its related components around it. If it lit you may want to replace the vertical output IC,Q301 and check the related components around it.
The horizontal and vertical output is on the deflection board where the flyback transformer.. you need to open the back of tv and take the board out to check...

all of the channel are resonding to the test. but you cant notice it bec 5.1 speakers, each channel are designed to respond to a certain frequecies. the L/R channel your talking about have the mid-range frequecies so it responds clearly compared to other channels...
hope that helps...
