Sony KDL-40V2000 HDTV Tuner Start-up Problem

I have a Sony KDL-40V2000, about a week old. It exhibits a strange behaviour. It tuned all the local DVB-T stations without a problem and allowed me to set them up as per the manual. When I turn it on cold, it gives me a message that the signal is weak or non-existent and doesn't display a picture. If I turn it off, then on again, it works fine...perfect reception and picture on all stations. It's connected to a good antenna. The HDTV tuner card in my PC reports "Signal 100% 31db" and works fine. The TV is on a shorter cable run from the antenna splitter/amplifier than the PC. So it should have a slightly better signal, if anything. Any suggestions? Thanks in advance. PS. I couldn't work out how to create a new model in this forum, so I had to post under the closest one I could find.

Most laptops have a combination of buttons you have to press on the keyboard to get it to output on the monitor output. Try pressing the FUNCTION KEY or FUNC/FN key usually found in the bottom left hand side of the keyboard. Keep that button held down while press one of the number keys. Usually the number key will have a picture of a TV screen on it. Might be number 8 or 9. Press both keys at the same time a you can switch between laptop screen, Sony LCD or you can have both..

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

SOURCE: TV Cable card slot loses signal immediately after channel find

THis is not a solution but a similiar issue. I have had a scientific Atlantia Cable card with comcast for 3 years no problems at all. Spent the entire day trying to switch to Verizon today. The signal comes across for about 10 seconds, pixelates and then fails. This happen after every start. We have checked the lines, tried 2 cards and reduce the signal. We gave up for today- installed the old Scientic Atlantic, reassigned it to comcast and all works fine Any and ALL suggestions are most welcome Thanks

SOURCE: hdmi port stopped working on sony bravia

I have a Sony Bravia model KDL-46s5100 that had the same problem. All HDMI ports stopped working. I don't know why this works but unplug the TV for about 30 sec, then plug it back in and hold down the power button on the tv for 10 seconds. Like I said I don't know why this works but it worked for me. Good luck.

Hi, I live in a flat in London with a shared rooftop aerial (no idea of spec). I have a Sony KDL-46X2000. The built-in freeview tuner doesn't seem to recieve any HD channels. Is the built-in tuner the...

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.

Greetings - Your Sony has the standard tuners for a current HDTV, NTSC (analog), QAM (cable), and ATSC (digital/HD) broadcast..

There's something going on with the Sony TV. It's a pretty high end TV so it might have some additional features that require you to do something different (I doubt it) but make sure you've been through the manual.

If you didn't get one with the TV you can download a PDF version HERE.

Good Luck and Thanks for using Fix Ya.

Is it possible to tune the channels of an integrated freeview digital box within a tv to a recordable dvd player


However, i see what your trying to accomplish - being able to record the freeview pictures you recieve form the Sony inbuilt tuner onto the recorder.. whilst being able to watch a different channel..?!

Well, you cant. If your Recorder has an inbuilt digital tuner then of course this would solve your issues, whereas if it is purely an analouge recorder and your in an area that has switched over then youll need some new hardware unfortunatly,.

Tuning Sony KDL 32U3000 for Sky TV

Hi Max,
I an not familiar with Sky TV, I assume it a Cable or Satilite Service.
Here are a few things to check.
  1. Press the INPUT button on the TV remote or on the TV control panel, cycle through all inputs and see if you get a signal.
  2. From the TV's Video Menu, set tuning band to Cable and not to Air or Antenna.
  3. From the Video menu Scan for channels, there should be a Auto Scan option.
Try these and let me know how it goes, I can be of further assistance.
