I installed a converter box in my motor home. the picture is great but there is a constant hum that makes it impossible to listen to the T.V.. Any ideas on how to fix this or if this is a common problem If this is a problem that may not be fixed are there any satellite systems you recommend?
ANSWER Greetings Brian thanks for submitting your question on our Ask An RV Question Page.
First let me tell you that you are not alone in experiencing the humming on your TV set's speakers when using a Digital TV Converter box. A lot of people are having the same problem. Certain DTV Converter Boxes are having more problems than others.
Let me take a moment to throw in my personal recommendation for a Digital TV Converter Box. My favorite is the Zinwell ZAT-970A Digital to Analog TV Converter Box. It is very highly rated by its owners and it seems to pull in more channels than other DTV boxes I have tried. It also has analog passthrough which is a must have option for any DTV Converter Box you buy.
I am going to give you a few suggestions on what to do to resolve this problem, but I am at a disadvantage, because I do not know the brand of DTV Converter Box you have and how you have it hooked up to the TV in your motohome. Follow the steps below and see if they help.
1. Double check all connections on the DTV Converter box and TV. Make sure that they are tight. Also if you are using a Coax cable to hook the box to the TV, try using a different cable just in the off chance there is a problem with the cable.
2. If you do not have a stereo TV, make sure that the sound settings for the DTV Converter Box are set to Mono (some boxes may not have this setting). I cannot tell you where to look for this on screen menu, check your DTV Converter Box Owner's Manual to locate the menu you need.
3. Make sure that the volume on your TV is set to low to mid range and use the volume control on the DTV Converter Box to control the volume for your programs.
