Open your smart TV's browser, go to whitescreen.cc, and click Go Fullscreen. Works on Samsung (Tizen), LG (webOS), Sony (Android TV), and most other smart TV browsers. Or connect a laptop via HDMI and open whitescreen.cc there.
An unexpected TV white screen usually means: a loose/damaged HDMI cable, a failing T-Con board or backlight, a software/firmware issue, or a source device problem. It is a hardware or connectivity issue — not related to this web tool.
Try: (1) Restart by holding the power button, (2) Disconnect and reconnect all HDMI cables, (3) Factory reset via Settings > General > Reset. If the white screen persists, the T-Con board may need professional repair.
Try: (1) Restart the TV, (2) Check all cables, (3) Factory reset via Settings > All Settings > General > Reset to Initial Settings, (4) Update firmware. Persistent white screens usually require T-Con board replacement.

White Screen for TV: Display Tool & Repair Guide
Two very different things: TV tool vs TV error
When people search "white screen TV" they usually mean one of two things: they want to display a white screen intentionally on their TV, or their TV has developed an unexpected white screen fault. This page covers both.
Using WhiteScreen.cc on your smart TV
Most modern smart TVs include a built-in browser. Open the browser app on your Samsung, LG, Sony, or Hisense TV, navigate to whitescreen.cc, and click Go Fullscreen. For the best experience — highest brightness, most responsive controls — connect your laptop to the TV via HDMI and use the laptop browser. You can also cast from an iPhone (AirPlay) or Android phone (Chromecast).
Why would you want a white screen on your TV?
Common reasons include: cleaning the TV panel (a bright white screen reveals smudges), backlight uniformity testing (does the white look even across the whole screen?), dead pixel checking, using the TV as a soft light source for photography, and white backdrop for video calls when the TV is visible behind you.
Diagnosing an unexpected TV white screen
If your TV screen has turned white without your intervention, the most common causes are:
HDMI cable fault — replace the HDMI cable or try a different HDMI port
T-Con board failure — the timing controller board that drives the panel has failed. This is the most common hardware cause and usually requires professional repair or replacement
Backlight failure — if you can faintly see a picture behind the white, the backlight is too bright or the contrast circuit has failed
Firmware bug — some smart TVs develop white screen issues after firmware updates. A factory reset often resolves this
Use our White Screen Tool to test whether the issue is panel hardware (visible even with this tool) or input/signal hardware (resolves when using the browser directly).
