Question about GPS

2 Answers

On switching on I got the NO FIX signal. I was advised by an electronics engineer that the GPS aerial was at fault and recommended replacement.This was ordered at a cost of £209.Today, and before fitting the replacement, I inserted an extra C-map disc and switced on to look at it and the set was fully operational and remained so all day.So I have lost confidence in the technician and fear that replacing the aerial will not cure a problem that could arise unexpectedly and give me huge difficulty. Your advice as to possible and checkable sources of breakdown in the system causing a NO FIX would be appreciated. Ken Brown

To fix the issue temparorily :just Disconenct the GPS cable from the unit. Turn off all power (turn battery off). Then hook everyhting back up and turn battery on then unit on.
but to fix it permanantly the technician gave you a right advice.it is caused due to weak aerial that catches weak signals.to fix it permanantly,just replace the aerial and the new aerial will be able to hold up the strong signal. i have solved this problem for many of my clients by changing the aerial.positively replace the aerial to get your device to work proper definately.
thanks for using fixya.please do accept and rate this solution positively.

  • Check to see if GPS is seeing serial port activity in the GPS Data Monitor panel
  • Is your serial cable plugged in and switched to the proper port?.
  • Not always aerial is prob
  • Does your GPS unit have a positional fix or is it in simulator mode
  • and if problem continues u should try to buy new or get it tested at service center

Why does my tv show no signal


It likely has a weak tuner, made that way, not a product fault and will work with catv, devices and boosted signals. Other than that, check inputs on setup menu and see if there's an option to switch from cable to aerial as well as settings for a default channel setup that switches between clear signal and a set top box for scrambled channels.

My northstar explorer 538 is not picking up signal were i am. what i can do to fix the problem


the northstar 538 does not have an inbuilt aerial (that is the 538i). You need to attach a compatible aerial and then you will be fine.

How do you hook up an antenna to a tv?


Optimum reception of colour requires a good signal and will generally mean that an outdoor aerial must be used. The exact type and positioning of the aerial will depend upon your particular area. Your dealer or service personnel can best advise you on which aerial to use in your area. before connecting the aerial cable be sure to turn off all main power switches. in the media recorder you will see an aerial connector one is the input and the other one is the output. your input is the antena and the output goes directly to your tv aerial input.

My rogers hd box the picture keeps flickering i've tried to reboot but it does not fix the problem


Have you tried a signal booster, i really do think that will help. Your reception can be to do with a few thing's, i.e. Position of your tv, Faulty receiver on your main (outside) aerial, A breakage or fault with the aerial cable coming from outside aerial to tv, or your outside aerial can just simply have a bad signal.

My tv auomatic off after 1 mi


1]...Please check that the sleep timer function is not set;

2]...Some tv's have a count-down timer & switch off if there is no signal input, either from the tv aerial, or av input;

Please check that the aerial is plugged in to the correct socket on the rear of the tv; test the aerial in another tv, to make sure it is working ok.

3]...It could be a problem with the remote/teletext panel?

for example, switching unexpectedly to standby, or changing channels unexpectedly?

4]...It could be a power supply fault;

for example, switched mode power supplies (SMPS) can cause problems; this could also cause the set to switch to standby mode.

PLEASE NOTE:

If the unit still switches off after 1 minute, even after checking the tv aerial is functioning properly, & is connected to the tv unit aerial socket ok, & the source is set to the tv aerial, then this could be indicative of an internal fault.

TV sets contain extremely high & very dangerous voltages, even after the tv has been unplugged from the ac power socket, on the wall, which could kill you!

FOR THIS REASON, & FOR YOUR SAFETY PLEASE DO NOT attempt to open or repair the tv unit yourself, unless qualified to do so - please take it to the tv repair shop;
only qualified tv engineers should attempt to carry out tv repairs.

I hope this information was helpful for you.

Thanks,

Steve.

Tv-- signal strength normal but signal on all channels "blipping" down intermittently causing freezing of picture. Have replaced aerial with high gain antennae together with aerial cable and...


When ever the picture freezes intermittendly the problem is usually poor connection on the signal line (antenna or connection on tv) or poor reception. Could be the tuner if the tv has one.To eliminate the tuner possibility try anther tv set if possible.
If you still cannot figure out the problem,let me know what kind of set up you have connected to your tv set.
Do you have a satellite or cable box and if you have splitters.

Can't lock onto satelite signal!!


Sounds like the aerial. There is a very fine wire in the center of the male aerial plug. If this is bent then you will have that problem. Aerials are hard to get, dealers say they are obsolete...update your model. Cheers, Peter
