How to Fix Sony NO-SIGNAL | VidCapto

If you see NO-SIGNAL on Sony, the stream or menu often fails because of Wi‑Fi, DNS, cache, or an expired session.

Likely causes

WHY
  • A captive portal or guest Wi‑Fi isolating smart devices
  • Outdated Sony app build or unfinished TV system update
  • ISP routing changes that briefly blackhole media ASNs
  • Payment method failed and the app still tries to stream

Fix steps

FIX
  1. Power down the device completely, unplug the cord, wait about 60 seconds, then plug back in and retry Sony.
  2. Remove a stuck Sony update, reinstall from the store, and sign in again.
  3. Delete offline downloads inside Sony to free space, clear cache, and relaunch.
  4. Run a network test on the device, note which step fails, then adjust DNS/MTU accordingly.
