The issue with the Sony KDL-32EX720 TV that powers on but has no sound or picture, and the remote does not work, could be due to several factors:
1. Presence Sensor: If activated, it may turn off the picture when no viewer is detected, leaving only sound. However, if the TV is left in this mode for 30 minutes, it enters standby mode.
2. Idle TV Standby: If this setting is enabled, the TV may switch to standby automatically after a period of inactivity.
3. Remote Control Not Working: - The batteries may need to be replaced. - The TV may be in SYNC mode; pressing SYNC MENU and selecting “TV Control” may restore control.
4. Power Cycle or Reset Needed: Performing a soft reset, power cycle, or factory data reset may resolve the issue.
If these steps do not work, contacting support or arranging a repair may be necessary.
