Sony KT-T25SF8 Dead, no video or audio, low level clicking noise

Was watching the TV and after hearing a small click, the screen went blank, audio went mute, front panel power indicator went off, and power low level clicking noise remained.

When powered off and allowed to discharge and back on can hear the degauss fire, and low level clicking again.

Most likly the Horizontal output transistor has shorted out because of cold solder connections on the flyback transformer, and or a bad capacitor in the sweep power supply and or, a bad flyback transformer. If the set Did not blow the fuse, then mopst likly you will have a problem in the main power supply where several parts in a kit form has and should be replaced all together.

Sound but no vision, black screen


It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.

Harish.......If you've lost both audio and video you'll probably need the upgrade kit. If it were just video you could get by for sometime with replacing the slow blow fuse on the s-zus board. Check your eprom chip on the digiatal board to see if it appears burnt. If so it may have fried. If you'd like the service manual I'll need your email address
