LCD tv imput help

[chas]

My 32" Polaroid LCD (Model 3200) tv has lost most its video imputs. It only
works on a cable coaxial imput. No screen problems with this imput, but I
don't have cable, only satelite. The HDMI and Composite only get the blue
screen.
.. . . .Can anyone suggest what board (video I imagine) would need to be
replaced in this unit?
in advance thanks to 1 & all.

A ground fault might cause this; the cable input is transformer-isolated,
but the HDMI and Composite inputs are not. Check grounding before you
plug in another set.
