Question about Sanyo DP32746 32 in. LCD Television
Please check back light is flickering or its LCD panel.
You can confirm flicker by watching back light at back side of TV, might need to take off back cover and observe back light coming from any tiny hole there.
Does Menu also flicker or its steady?
Let me know to proceed.

Usually the first thing you need to check is your HDMI cable and all the connections at the back. Dish network probably has composite video outputs AND RF outputs. You should not have the problem with the CV outputs, but you'll need to have correct cables as specified and have the TV setup look at the video inputs, not the RF.
The only way to troubleshoot this sort of thing without test equipment is swapping out components, doing comparisons between different approaches, reasoning out what is going on.
IF the problem is your RF modulator on the Dish network, which seems unlikely because of the fact that your cable did it too, you could use a distribution amp to boost the signal.
If the problem is a bad RF connection at your TV or via the coax, you MIGHT seen an improvement by boosting the signal. Cost of a distribution amp at the local hardware store is $20. Some older TVs have 75 and 300 Ohm inputs. Are you using the right one? This matter because there are other internal components that might be involved, misfired, broken, missing.
To me, it sounds like the TV is insensitive to RF. The old cable box isn't. It either demodulates the signal and it comes out stronger, or it has an internal distribution amp that does the boosting directly.
Please do accept this solution and revert for further assistance.
