The digital tuner seems to work intermitantly resulting in a choppy picture and sound. Is it worth replacing the tuner or should it be scrapped

check your brakes for wear or foreign object such as a stone in the wheel

Hi,

Your TV has a dual tuner - one for analogue and one for digital although they are contained on the same tuner board. It's possible that the digital tuner has failed, in which case the tuner board will most likely need to be replaced, but often this problem can be resolved with a "hard" reset. Turn the TV off and unplug it. Remove all the cables from the back, leave it for at least 5 minutes and then re-connect only the cable from the tuner source. i.e aerial/antenna. Make sure you are in Digital TV mode (DTV), then run the channel scan again.

If it works turn the TV off, re-connect all of your other devices and you should be able to resume using the TV as normal.

If this doesn't work, you may need to have the digital tuner replaced. The analogue and digital channel feeds are from the same source. As the analogue channels are working there is no obvious fault with the feed or cables.

Please try this first and then post back for further assistance if needed.

I'm a video game programmer with 20 years experience in software, and have a reasonable understanding movie playback software.

I also have a Nikon (S6100) and the problem is nothing to do with PC memory or CPU speed. The Nikon creates a broken version of the MPEG-4 AVC H.264 format, which results in choppy playback. I've tried Quicktime, VLC and the cameras own player - ViewNX2 - same result for all of them.

Converting the buggy .MOV files the Nikon creates to a .avi format produces perfectly smooth (flawless) video, but with the sound out of sync. I can also create perfect quality (lower res) DVD video, but with the sound missing.

I have spoken to Nikon about all this and they are quite simply clueless and will take no responsibility. As there is no firmware up[date for this camera I'm taking the camera back, as it is basically flawed.

I've read a few sites with customers complaining about choppy video for this camera, so it looks like the model itself is flawed.

Replaced the power cord,it have intermitent power input.

this is just the tuner and it can be replaced or it just needs some soldering but i fix these and i can tell you it sounds like the tuner is failing and needs replaced , the tuner can be about $80 and the repair can very between 50 -$60
hope this info is worth a fixya as other ratings only hurt our rating
and if you need more assistance I'll be glad to help

Remove the battery cables and let sit for about an hour. This resets the computers/sensors. Reinstall the battery cables and the car should run choppy for about 15K(take it for a drive) then it smooths out. This is what we tried, but never experienced the choppy ride later. Try it it should work.

Hello frogman,

The freezing of the picture denotes a loss of signal on a digital (Having a ATSC tuner) TV. If your TV is not digital (Having a ATSC tuner) then it is the device that you have connected to the TV (Cable Set-top Box, DTV Tuner, etc). In the likelihood that it is your TV I would suggest getting a better antenna first if that does not fix the problem you may have a tuner problem. However lets not look at it that way first. What we need to do is to determine if it is the TV of whatever you have connected to the TV.
First unhook the connection you have from the cable to your F connector of the TV (you should see snow or a blank screen) connect a antenna to the F connector of the TV, do you see a snowy picture or a clear sharp picture (snowy= NTSC tuner, clear-sharp= ATSC tuner). If the tuner is NTSC then check you cable device and the connection between your TV and the device and the cabling between the device and the wall. If the Tuner is ATSC then you will have to check all of your connections, and finally if the tuner is bad it has to be replaced by a qualified Tv repair shop.

I hope this helps,

Thank you,

While there are other possibilities, this is a problem which is commonly caused by bad solder connections that form in the tuner. When you're using the video sources the tuner is out of the picture (sorry, I couldn't resist a pun) so you don't see any problem. It's relatively easy to fix, but it means removing the tuner from the board inside, opening the tuner and resoldering the bad connections. This is a nice TV, so it would be worth getting an estimate for the repair. Because of the time involved, many technicians would rather simply pull the tuner and put in a replacement. See if you can find one who will repair the tuner instead. I always did when I was on the road, and it didn't really take that long. It saves the cost of an expensive part.

Your TV's tuner is the problem. 1st thing to try is just to sesolder its connections to the main circuit board. If that doesn't work replace the tuner. Also could put a meter on the power coming into the tuner and see if it is drooping in sync with your picture. Tuners are not that expensive to replace.

This usually a problem on/near the horizontal section of the TV board caused by solder that losses its contact thats why you need to bump it sometimes for the picture to come out. To remedy this just try to resolder any parts that you suspect seems to loose especially in the part where the components tends to get hot when operating, this usually are the horizontal section or the power supply section which is very common.
