Why is my Sony FD Trinitron KV-28DX30U CRT TV showing no picture and no sound?

  If your Sony CRT TV shows no picture and no sound, the possible causes are: the TV is not plugged in (plug in the TV); the TV is in standby (press the button on the front of the TV); the aerial is disconnected (check the aerial connection); there are no digital transmissions in your area (tune in the analogue channels available using the ‘Manually tuning the TV’ instruction in this manual, then contact a local installer to find out when digital transmissions begin in your area); or you have an unsuitable aerial (change your aerial to cover the channels used by digital programmes. Contact a local installer).

  If your Sony CRT TV has a good picture but no sound, this could be due to the volume control (press the + button on the remote control), or the button marked on the rear of the TV is pressed in (if is displayed on the screen, press the button on the remote control).

  David EnglishAug 11, 2025
  If there is no picture on any channel after digital tuning on your Sony CRT TV, check the aerial connection. It is also possible that the signal is weak, in that case you should contact a local installer to find out which transmitter you should be pointing your aerial at. Another possible reason is no digital transmissions from the transmitter you are currently using, in that case you should contact a local installer to find out which transmitter you should be pointing your aerial at.

Why is the standby indicator flashing on my Sony CRT TV?
- F
  Frances NicholsAug 15, 2025
  If the standby indicator is flashing on your Sony CRT TV, it could be that the Digital mode Timer Record is active (regular flash). See ‘Skipping programme positions’ section. Alternatively, it may indicate a fault (irregular flash). In this case, do not open the cabinet, refer to qualified personnel.

  If your Sony CRT TV has poor or no picture (screen is dark) but good sound, the issue might be the picture level adjustment. Select on the TV menu system then adjust the brightness, picture and colour balance levels.
