Frequently asked questions
Is anything wrong with the TV?
No — it's just a fake full-screen animation of TV static and a "no signal" banner. The TV is fine.
What are the colour bars for?
They're SMPTE test bars, the standard "the signal's gone" screen you've seen on TVs your whole life. Ours are decoration only.
