Robert,Sorry but I don't understand your post.You say when you removed the
board to t/s;started working.What do you mean by it started working or do
you mean the unit would then turn on but with no useable sound or pix.Can a
tech just unlpug the 3 ribbon connectors & get the same result.I'm not
familiar with these Gemstar modules & would like your opinion...TIA......
