Insignia NS-F27C 27" Flat Tube TV

The input keeps switching back and forth on this tv by itself and we can't get it to stop. If you hold down any button, either on the tv or the remote it will stop switching, but as soon as you let the button go, it starts to switch back and for again... what is going on?

    I am having an identical problem. The input keeps switching on its own.

    I am having close to the same problem ..

    If i press any button on the remote it just switches to the next input.

    I cant access my cable channels, or any channels for that matter. It doesnt matter what button i press on the remote, it will just move to the next input option.

    I tried the buttons on the TV itself, they are inactive, except for the power button of course.

  • popnyah Nov 30, 2007

    Yeah, whats going on!!!! same thing happened to me. Whats up with this crappy Insignia TV's . front buttons are innactive and just switchs by itself.

    I've got the same problem with my NS-F27C. It has now migrated to the stage where the front panel keys (menu, ch+/-, etc) are not functioning, and the tuner i/p is skipped when changing the i/p on the remote. Also, no video or sound on any i/p, just the blue screen and text. Before I pay for a service manual, has anyone who has had this fixed (under warranty?) know whether the fix involed replacing any components, or was it a micro/memory re-programming exercise thru the remote/service codes?



    Thanks.

I repaired it!
My Insignia TV set started showing the same problem reported here, after a static discharge sparked when my wife was cleaning the TV with a cloth.
The information provided by bill47 proved to be very useful. I tried to find the data sheet of the large 64 pin IC, TDA973, I found the TDA 9351, which may be from the same family. I measured the voltage at pin 6 and it was approx. 0.2V. I imagined that if I forced that voltage to a higher value the IC would believe that no button is deppressed and so return to normality. From bill47 comments and my measurements of resistance to ground with the TVset off I estimated that a voltage divider was formed with a 3.3K resistor from +3.3V to pin 6 and 180 ohm to pin 6 to ground. In those conditions, I calculated that if I add a 18 ohm resistor from 3.3V to pin 6 I should force the voltage at that pin to 3V. I first tried with a 120 ohm resistor between pin 61 (peripherial power supply in) (+3.3V) and pin 6. This moved the voltage to 1.7V, the failure persisted, but the effect was different, as if another button, located at the rigth of the Input button, was permanently depressed. This showed me that I was in the right trak. I refined my calculations and replaced the 120 ohm resistor to 15 ohm. That raised the voltage at pin 6 to 2.5 V, and solved the problem. The front panel buttons were disabled (except for the Power button), but that is not a problem, I never use them, I always use the remote control. So I can continue enjoying my Insignia TV set! Thank you bill47 and all the other people who posted their comments.

    Great Post i have the same problem, BUT i don't understand if you jump 15 ohms resistor directly from pin 61 to pin 6 or add to 3.3k in series or parallel?
    Would appreciate any help.. really really helpful post....thanks

Purchased the service manual, and traced problem to the "KEY" input (pin 6) of the Philips universal TV processor chip (TDA9373 - the large 64 pin DIP on the main PCB). This single pin connects to all the front buttons/momentary switches making it extremely vulnerable to ESD strikes. Each of these switches is configured in a "resistor ladder" voltage divider circuit, which produces a unique voltage at pin 6 for each of the 7 switches. When no key is pressed the voltage on this pin should be around 3.3V (via 3.3K pullup to the 3.3V supply). My defective unit measures only 0.17 volts -- suggesting ESD damage. This condition confuses the processor (thinks a key is constantly being pressed) which explains the behaviour of constantly changing inputs, etc. In my case the front panel power button still operates because it shorts the input to ground (zero volts) which is still properly detected. Unfortunately the only remedy is to replace the part, which is likely fairly expensive. Because there is a microprossesor core in this device, it may have to be purchased directly from Insignia/Haier to ensure it is programmed correctly for the particular TV model. (Have not yet checked price/availability.)

Sorry for the bad news!

Just sat on hold with tech support for over a half hour, someone finally came on and said this:

Unplug your TV, and disconnect everything you have attached to your tv (antennas, cable wire, input cables from VCR/DVD/cable box, EVERYTHING) and let it sit for about a half-hour to allow the tv to return to its factory settings. Then, plug it back in and see if it works.

It has not been the full half hour yet, but if I don't repost here, then assume that this solution works!

    Well, the above solution was a no-go for me.

    Called tech-support back and they informed me that I have to get in touch with the in-home service they offer and have a repair person come to my house and fix the tv. This is a free service since my TV is still under its 1 Year Warranty.

    so much for the easy fix-it-yourself answer, I guess!

    **If you are Canadian and purchased the TV from a FutureShop, you need to take the TV directly into the store and have their technicians deal with it. The in-home service that Insignia put me in contact with was at a BestBuy store, and they said that if they were to send someone to look at it, I would be charged initially and I would then have to submit the charges to the manufacturer to be reimbursed. It is easier to take the TV into the store and deal with the technicians there.**

You may try using the power switch on the TV itself instead of the remote. I have had trouble where the remote turn on doesn't work for the video, holding down on remote button longer seem to help.

Also you may want to try another input to the TV -so connect up input wires from your cable/sat to another one.

Cannot get AV Mode


Hi,

There is a TV/VIDEO button on frond panel of the tv. When you press each time this button then you will able to access different video inputs. if the button is inactive the probably the micro switch for TV/VIDEO button may be faulty. also check the same with the remote. If its doesn't help then try to reset the tv to factory default setting. For that you need the remote. Keep in mind that when you reset the tv to factory default setting all the memorized parameters will erased(like channel memory, personal preference setting etc ). For reseting the tv to factory default do the following

1.Turn on the TV.
2.While holding down the RESET button on the
remote control, press the POWER button on the TV front panel.
The TV will turn itself off, then back on again. Release the
RESET button

The tv input keeps does not stay on the correct input eg. av1 even though it is the only device hooked up to the tv. After a short period of time it starts to scroll though the other inputs and stops on...


That tv input it is could be shorting out or it dying,if it is ramdomly switching to other inputs.Tries tv unplug,replug the tv back like about an hour later for the tv to a resetting itself.Go into the tv Menu go to PICTURES,go down to do a resetting to do a whole resetting of the tv Tuner signal board to go back to the factory setting,this problems should be solved.If not just used and connected other input ports connections on the tv.

My remote has stopped working and I can't change the tv from coposite 1 back to tv. how can ido this without the remote and what can I do to get the remote working again?


There may be an input button on your tv itself on one side or the other. If you press that and then use the up and down arrows which are usually the channel buttons and volume buttons, you can move the highlight up and down to choose the input you want. You may also be able to get there through a menu button if input is not an option. Let me know what buttons you have.

Hello,

Turn your TV on by pushing either the power button on the front of the TV or the power button on the remote control, which is located in the upper right corner of the remote.

Step 2
Press and hold the "up arrow" button on the remote control. The up arrow button is located in the middle of the remote, to the left of the "Input" button and below the "Picture" button.

Step 3
Press the power button on the TV while still holding down the up arrow button. The TV will turn off and then turn itself back on.

Step 4
Release the up arrow button. Once the TV turns itself back on, it will restore your TV to its factory settings.

Hope this helpout.......

Did you try "Input , 2,5,8,0" ? May I know what exactly is the problem?

Caution:Be advised that the service menu is to be accessed only by trained professionals. Keep a notepad handy. If you accidentally change some setting then pen it down go back and change it again. Pen down the values of anything that you may wanna change. Be very careful.
