''Brought a Coles $259 Nu-tec DVD/Tv combo got it home and set it up with a indoor digital ''

Poor English!

It should read; ''Bought a Coles $259 Nu-tec DVD/Tv combo, brought it home and set it up with a indoor digital ......''

No,Ur Digital antena not getting a good signal,because of lanscape like hills or big buildings,blocking the signal,that why u not getting good signals,or no signals at all.Buy another name brand digital antena with a stronger signal amplifier.Or buy a digital roof antena,well help or solved these problems.

TV sets do last only about 10 years, the picture tube is going out, they are very expensive to fix so you will have to replace the TV soon. Good luck to you!

A simple pair of rabbit ears (standard dipole antenna) should do the trick. You will have to set the source input to NTSC/ATSC and connect the antenna to either the analog or digital F- connector inputs if you use a RF splitter you can use one anatenna for both inputs. In any event try this first.

Thank you,

ATSC tuners ("D/A converters") pick up signals off the air just like old school television. It sounds like you are just not getting a signal of sufficient strength. A weak analog signal looks like a "snowy" picture, which most of us are used to. But, the new digital channels quickly go from a perfect picture to none at all. It's basically all-or-nothing.

Try attaching an antenna to your converter. I know you can buy a new antenna from your local big box electronics store which is labeled "Terrestrial HDTV" or something, but that really doesn't mean anything. You can use any old TV antenna. Even a quality FM antenna (with an F-Pin coax connection) may work just fine.

When setting up the antenna, keep in mind that different channels are transmitted from different towers, in different locations with different strengths. Move the antenna placement and position around (just like grandpa had to do). You may have to make a compromise to get the best signal for your favorite channels.

I have a Mitsubishi VS-60705 and the picture flutters vertically and horizontally i need to be fixed

It appears this problem is due a failing CCD device in many brand cameras. All the manufactures use the same source(s). I have not persued Casio as yet, but other companies are offering a recall to replace the CCD for free. I plan to use this approach with Casio. Search the web for "failing CCD in digital camera", it describes exactly what we are observing.

call tech and suggest to repair the horizontal drive ..

This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.

A 10 year old RCa most likly has a bad Horizontal output transistor as well as the main High Voltage transformer and The transformer is no lonmger available from RCA. The replacement wont last longer then a year if your lucky. My advice on a set this old ?? Buy a newer one!!
