My Sony KDL-52xbr4 was working fine until I did a re-scan of the digital channels. After the re-scan the TV finds no digital channels. All other TVs hooked to the same antenna work fine. The sony scans up to 8 digital channels then goes black and aborts the channel scan. I end up with two spanish speaking analog channels only. I have ended up using a set top NTSC box to get all of the channels.

If you've tried different antennas did you attempt to re-tune/re-scan for additional channels after switching? For digital channels to be detected they must be scanned for, so consult your manual on how to perform an automatic scan of the digital channels available in your area.

Sure, but not at minimal cost - it's a sony! Probably the t con board.

Three suggestions:

1. Try to hook cable direct without box to see if same problem---ie the box might cause this problem.

2. Check to see if it does it with DVD or when you change active inputs.
3. If number one contact cable provider as box may be your problem.

U are using a antenna to do a recieving for a Free AIR DTV incomming braoadcasting tv signal channels siganal?Yes.U are using two different tv antennas signals wright?The Sony one just require a stronger and a better antenna signal,not all flat LCD or Plama tvs recieve the same strenghth signals.Some tvs design require a strong or a very strong signals strenght to get all the tv Free AIR DTV braoadcasting tv channels.Buy a better tv antenna design like a Digital amtenna will solved this problems for the Sony tv.

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.

If you do the setting up using device codes scan correctly (page 25 in the user guide ) it worked with my sony bravia KDL-32L5000.

If you are connecting the cable directly to the TV with no cable box, you'll select Home on the remote control. This will put the menu on screen. Scroll down until you find the Channel Settings option. Set the Cable category to On, Select Auto Program to automatically scan for all analog and digital channels. You can then customize which channels you want to remove when scanning channels.

may be tv main board problem ..if you can switch  cable HD  box you can  save money     

Hi,

Power the TV off and uplug from the mains, now remove the aerial, now press the standby button the TV, now plug the mains back in and switch to a DTV channel, wait 5 secs and then put the aerial back in whilst still on that channel, now rescan.

If that didn't work, reset the TV to factory defaults and rescan again.

Thanks

Ur tv shouldn't set in cable mode, if u don't have pay cable,or satalite,extra..Should set in air channels.Buy a digital antena or out side roof antena u get all the channels airs.
