    HDTV channels on Westinghouse SK-19H210S roam on own. The channel changes without input to another HDTV channel - sometimes the sound matches - other times it continues from the original channel. Signal strength for both channels is 80%.

    I have the same problem. A Samsung 40a656 connected to a Targa hdd/dvdr and Digital set top box. Input source changes between all three without warning. I intend to introduce a freesat hd receiver into the equation and would like to know where the problem lies.

    Hi Andy.

    Have been studying my samsung stock fault notes for your tv model The only problem I can find for your set is similar but not the same. this is what I found.

    ( Symptom : There is several complaint from some subsidiary about DTV ''No Signal'' Issue. If the TV is under the standby mode more than 15min after watching it in DTV Mode. Intermittently, DTV signal was not detected(No-Video) and appeared the No-Signal Information !X Note. This problem occurs only using with specific Tuner that has some defect.

    Basically they are saying that if you watch DTV freeview using the TV tuner then put set in to stand bye for more than 15mins after you switch back on again the screen can come up NO SIGNAL DETECTED. they then say this only happens if the set has a certain type of tuner fitted which is known to have this problem.

    Now your problem is nothing like this I would do few tests.

    First put tv on Sky then take sky remote & tv remote out of the room so there is no way either of them can interact with your tv set. And see if fault still happens.

    If it does something very strange is happening & I could only advise you to return it to where you purchased the set.

    I am not in any way saying Samsung arent any good as personally I like there stuff & have A 42 inch Samsung my self.

    The stock faults I mentioned all manufacturers have these Sony Panasonic etc they are problems that have been reported back to the manufacturer during testing & when the items are sold to the consumer & develop problems.

Tips to operate without remote

You might try hitting the MENU button on the tv itself to see if you are able to select input / source that way. Some TVs also have the Aux Inputs selected by scrolling through the channels until you come to the aux inputs.

HDMI conneection wont override tv picture

I am a sky engineer (not a subby)
the reason this does not come on straight away is because a Scart lead send power upto your telly when it is turned on. Telling the telly that this is what you want.
Unfortunately HDMI does not send power upto the telly. There are ways around this. ON Samsung, Panasonic and Lg tellys you can go into a secret menu and apply something called HOTEL MODE this allows you to change the av input so it would automatically come on your hdmi 1,2,3, etc

In your case follow my instructions below

go to the hdmi you are using for your Hd

on the sky remote
Press SELECT and GREEN until LED flashes twice.
Press HELP then SELECT and the LED will flash Twice. what this mean is when you press your Sky button, tv guide, services or interactive button to turn the sky on this will automatically change your av/source on your telly to the sky HD for you

You owe me a pint
Have a good one

Lost ITV channels and C4

I think you need to get Sky because it will give you 100% coverage of all terrestrial channels. You may need to retune the television otherwise just get sky

Probem getting sky to work with a new TV

An HD TV connects in the same way as a standard TV.

Connect a scart lead from the TV scart of the Sky box to the TV.

When you switch on the Sky box it should automatically switch the TV to the correct external input.
