    Im using my TV for the first time in my new MH but every time the water is run the TV goes blank .Had a Aerial fitted by the dealer before I bought the van ; have they connected it incorrectly or is there something that I can do to solve this. The Aerial is a Status I believe and there is a little box of tricks labelled Vision Plus digital amplifier in the cupboard below .Any feedback would be most appreciated . Thanks (n)

    There should be a light on the amplifier, does it go out when you turn on the tap?

    Sounds like an interference problem. Fitting a capacitor across the pump terminals might cure it. Cost should be very low but I suggest contacting the dealer first.

    I would say you are low on battery power, every time you use the pump, not enough electric to keep the TV on.

    The vision plus box is a signal finder.....when you switch it on you will notice a red light.........if you rotate the aerial to the best signal available it should go to amber then green.

    Each time you move you will have to retune the tv unless you are in the same area.

    Your problem with the tv going blank may well be your battery power is very low and the tv is not getting enough when the pump runs.

    Run the T.V. from mains power if you can & see if there's a difference

    Connecting the T.V. to mains power will / should eradicate any battery power issues too & eliminate that potential cause.

    I agree with low battery power.
    The tv will have a minimum working voltage and starting the pump may be enough to drop the voltage below the minimum required.
    Your battery may just need charging, or could be past its best and not accepting a full charge.
    If you have a voltmeter connect it across the battery and check the voltage, turn on the tv and note the battery voltage then start the pump and check the voltage with the pump running.
    If it drops considerably the battery may be kaput....or needs a proper charge then test again.

    Thanks for the replies ,I'm running on mains as my TV is not 12v, the Batt should be OK as it should be new as is the van. The vision plus box light is on red as that is all Iget in any position that I move the aerial .I will have to speak to the dealer when I get home about this and also I have just realised that I don't have any instructions for the extras that they fitted, which I assume I should have . Once again thanks to all .

    Melvin, there is a little dial in the right hand side of the vision plus box......you can turn it clockwise to boost your signal........failing that you might have to put the aerial in the vertical (red) on the pole that goes through the roof. By turning the handle at the bottom.

    Your signal booster will be running on 12v also, so the problem might still manifest itself through your 12v system.

    Nothing worse when you cannot tune in.......even though there is never nothing on.

    The first time we used our Avtex T.V. in Llandovery 3 weeks ago the signal finder / amplifier would not turn amber or green & was on red but to our surprise we had a reasonable enough signal to pick up most channels - why this is I don't know as i'm not an expert - just saying our experience.

    @Melvin
    Might not be the exact model fitted but may be of some assistance?
    I've got the manual for the 530 as well but too large to upload. Could e-mail to you if of any use.
