OK we move on...

Please whilst the fault is there press themenu button of the sets OWN remote control does the menu come up normally please?or is this affected?or does no menu come up?

Customer: replied 8 months ago.
Please don't call me.....I think it might be the Dish network box. Will let you know.
Expert:  Anthony_Infotech replied 8 months ago.

No one will call so long as you do not accept the phone offer, we can work this out its your call

Customer: replied 8 months ago.
Menu and Home both come up.
Expert:  Anthony_Infotech replied 8 months ago.

It is in that case very likely (assuming you have rebooted the box) to be either the box itself bad OR the lead from the box to the TV, if its HDMI please replace that lead as we do have a lot of trouble with those

Expert:  Anthony_Infotech replied 8 months ago.

In the case of dish that also includes the dish itself LNB (electronics at dish itself)

If you need more help let me know, ultimate proof >>>if you try another input like a DVD player and that works as I suspect it will then that clears the TV as being responsible

Please consider rating the answer positively with the rating bar of stars at the top of the page, rating me positively enables me to receive payment from the site thank you, ***** ***** question is open for 30 days

Was not the Dish box - I changed it out and the TV is still doing the same thing.
Expert:  Anthony_Infotech replied 8 months ago.

If you try another input like a DVD does that work?

Have you swapped the HDMI lead (assuming you are using one)?

Customer: replied 8 months ago.
Was not the Dish box - I changed it out and the TV is still not working. Dish Network is sending a tech out here by noon - will let you know if he decides if it is the TV or the connector
Expert:  Anthony_Infotech replied 8 months ago.

I can tell you if it is the TV if you try another input like already outlined, you have the info, you could not work this out, seemingly now you can, if you do not wish to continue please just say I have paying customers waiting thank you

Expert:  Anthony_Infotech replied 8 months ago.

I can also tell you that 99.9% of the time we get this issue it IS the box one way or another so your replies are not making sense please read above thanks
