i have one of these great sets but there is one small problem, no
picture when i connect to either of the coax inputs. i get the menus
to work on these inputs, but no picture or sound. i was told to check
two capacitors in the IF block on the main board. if anyone knows
which two to change i will be forever gratefull. im also loosing the
bottom half of the picture, it is squashed into the middle of the
screen from left to right. i was told to change the stk4274 on the
main board and that should solve my problem. ne suggestions or ideas,
would be greatly appreciated.

Thanks,
Chris
