Toshiba cf27c30 tv in ant mode i can not recive all chanels how do i switch it over

if it is with hdmi input call toshiba--free software upgrade

No your tv does not need a tuner if you are not hooked up to the reciver. If you have one of the recivers that does two tvs then you just need to find the right chanel to put the tv on. It can be any where from 56 on up to 166.

Check in the back of the unit to see if there is a switch to select channel 3 or 4. Or try to select the channel from the remote.

For the Dynex ZRC-102 remote control channel switching.

1. Press the MENU button and select SETUP.

2. Go down the list and select FAVORITE CHANNEL MODE and switch it to OFF.

The +/- CHANNEL buttons will then switch channels when pressed.

the tx/rx liight is green when your radio is recieving signals and turns red when you are sending signals. the ANT light is red when your SWR is too high (over 3)

1. turn the knob labeled swr cal all the way counter clockwise
2. set the rf swr cal switch to the CAL position
3 key up the mic and hold it while you rotate the swr cal knob until the needle reaches the swr cal postition
4. set the swr cal rf switch to the swr position
5. key up the mic while on chanel one (record the the number)
6. switch to chanel 40 key up the mic (record the number)
if the number on chanel one is lower than the number on chanel 40 then your antenna is too long.

Which sattelite?
Which band?
Which country?

that will solve your problem
