I am trying to set up dish network on this tv i can not get the channel to change to 73 only 70 and 76 i have no remote control for this tv just using whats on the tv

Hello. If this has not yet been resolved, I have some simple steps for you that will help you out.
First off, it sounds like the remote needs to be programmed, and since I do not know the particular DISH remote you have, here are the steps for a power scan, which will scan the TV for the correct code.
1. Hold down the Clear TV button until all lights at the top of the remote light up
2. Press the red TV POWER button
3. Press and release the up arrow on the remote about once a second until the tv turns off.
4. When it turns off, press the # (Pound) button
5. Try powering the tv on/off, and try the volume. If one or more of these functions do not work, start over at step 1 again.

Then once you are on 73, that picture will work. You can also try the alternate channels, which are 22 and 21. That may also give you a picture. I hope this helps!
