Sony KDL-46W40XX/42XX - lost digital channels

Hi there.. I have a Sony KDL-46W4000 european model and i have a problem with it. I receive my TV channels via DVB-C both MPEG2 and MPEG4 channels. It suddenly started to periodically delete all my digital TV channels, and i have been forced to search again, and sort all my channels again. Is there a way to get a firmware update or something? Sony does not send firmware out though the cable TV here in Denmark. Can it be done with a USB stick? And where do i download the firmware? Here's my product information on my TV: 0004324515 B.U-EG-Q-C.T.GG-A.CY.Z Thanks - Mikael

SOURCE: Sony BRAVIA KDL-40W4000

Hi there,

I've been looking into this myself as I've also recently purchased the KDL-40W4000. I was watching a murky old film and was getting a bit of sludgy ghosting but found that by reducing the contrast to 25, setting the backlight on low, colour on neutral and the brightness about 40-60 (and taking ALL advanced noise functions off), this reduced the ghosting considerably.

BUT, this is quite a cool and dark image. If you watch standard TV and films mainly, a variation of the Cinema setting is probably the best overall setting i.e.

backlight: min
contrast: 79
brightness: 50
colour: 53
colour temp: Warm 2 (although Warm 1 is less yellow and still fine)
sharpness: min
noise reduction: off
mpeg nr: off
contrast enhancer: off
colour space: standard

These tv's receive digital on the atsc 8vsb. Do you know what there broadcasting in New Zealand ? It could be that a Sony tech there can fix your problem. The TV can be set-up for a different digital broadcast and Sony is all over the world even in New Zealand .

Check all your connections in the back, if they're all good replace the main board in the tv.

Using an antenna on KDL-32S5100


No you do not. Your Sony already has a digital tuner. If you are not getting all the channels you think you should, you just need to keep progromming your TV with the antenna at different locations to maximise your signal.

Make sure you have a good connection from antenna to TV. Check antenna and cable and cable connection to TV. Select DIGITAL button on TV remote when wanting HD channels. Remember HD channels are always digital. Also, any given TV station may not be broadcasting in HD at a given time. They can broadcast in digital but in standard definition sometimes. Your TV has a built-in DVB-T tuner. Try executing a channel scan to pick up all available channels. On-screen menus go to Digital Setup, then Digital Tuning, you can auto-tune or manual tune channels. The TV should take a few min. to scan thru available channels and store the channels its finds. Check with anyone in your area to see if they get HD channels (it is possible to be outside of the range of some TV stations) Your TV is a 2006 model and should still be compatible with local digital TV broadcasts but keep in mind digital signals could change in the near future (DVB-T2) and you may need a tuner/converter box to make the TV compatible.

I have the same problem, the only solution I found so far is to disconnect the TV from the mains supply - not very comfortable. The problem seems to happen more and more frequently.

I have lost digital reception. I can play DVDs and get analogue TV.


You need to make sure your reception is strong enough to receive digital reception otherwise you will only receive analogue reception and dvd playback ability is normally nothing to do with the TV's reception.
Ensure you have strong reception before doing an auto tune to search for the channels. Good luck.

Sony Bravia does not see my digital channels


Hi buck lite,
Your cable company is telling the truth, you have digital cable. When auto scanned for digital channels the tv is lookig for OTR(over the air) signals. These are broadcast signals you will need an antenna to receive. Depending where you are and the type of antenna you use you probably could pick up some digital channels. Let me know if this helps and please rate this solution. Lone99star
