Insignia/tvflat32" automatically channel will change to ch8

please check touch key board i think it is defect

thanks lal electronics

The SWR cannot be changed by rotating this knob. The SWR function allows you to determine the SWR or "match" of the antenna system and transmitter on a specific channel. The entire process must be performed whenever you want to know what the SWR is on a different channel. The SWR/CAL button toggles the meter between the CALIBRATE and SWR modes.
Set the radio to CH1. Press the SWR/CAL button. The radio CAL(ibrate) mode is now selected. Press and hold the mic PTT (or push to talk) button. Rotate the SWR knob as needed to adjust the meter indicator until it is on the SET mark on the dial. The meter is now calibrated for this channel.

While still holding down the mic PTT, press and release the S/RF SWR CAL button to the SWR setting to read the SWR on the meter.



This entire process should be done for Ch 20 and Ch 40. You must go through the CAL procedure for EACH channel before attempting to read the SWR.


Changing the SWR requires that the antenna be lengthened or shortened until such time that the SWR can be reduced no further. Typical SWR across the band may be:


CH1 - 1.5:1, CH20 - 1.1:1, CH40 1.5:1


or


CH1 - 2.2:1, CH20 - 1.7:1, CH40 2.3:1


The "dip" in SWR on CH20 is typical, as the antenna is the perfect length on only one channel - it will be come slightly too long or slightly too short as you tune up or down from CH20. The further away from CH20 you go, the poorer the SWR will be. You can "slide" the dip to any channel you prefer - say CH8. If you tune for lowest SWR on CH8, You might see CH1 with a 1.2:1 SWR, CH8 at 1.1:1 SWR and CH40 at 2.5:1. All are acceptable - sort of. Many manufacturers say up to 2.5:1 or even 3.0:1 matches are ok, There's no reason a quality antenna can't be tuned for optimum SWR in the middle of the band (CH20) to have less than a 2.0:1 SWR on CH1 or CH40, unless there is a ground issues or bad cable / antenna / connection somewhere.


You can view the manual here. I hope this helps & good luck!

The channel memorised on channel 8 is set to another AUDIO frequency or audio mode. You need to check the setting of the channel 7 to confirm and reset using the manual tuning to reset the audio mode.Since you have not mentioned the place of residence, say for instance PAL system has different audio modes.

Did your cable company change the order to your channels? This is a rare problem.

if you have set top box ,go to main menu ,check on restore factory settings ,put in default password 0000 and press ok,restarting the set top box automatically,waiting for some minutes.

restarting starts scanning all channels one by one and put them on their respective location in channel store.

now ,enjoy with all channels.

same process is done with tv if u have't any set top box ,only RF input from ur cable operator.

1. Cable company sending something through the line. Also th insigna has a different tuner. Also can the insignia find the digital channels using an antenna?

Try using the manual buttons and keep pressing channel down until you see the lowest station you receive, then go slowly.
Maybe Insignia put the inputs into the channel search automatically.

Go into the menu to the "Search" tab, channel down until you are on "auto search" then press "volume up"

this will automatically add channels you can get, you can manually change skip settings there too if you want to not see a channel you get or for some reason add a channel you don't get etc.

check channel up & down buttom if stuck up. if not, replace eeprom as possible. good luck!

I have one in my shop with the same problem. Power is the only function that works. I repaired the power supply six monts ago. Now it looks like a bad digital processor board which is non-repairable. I can't believe what's happened to the tv business. Absolutely disgusting!
