29 Dec.2022 hi, I have the problem "no signal". My 2011 Visio TV which has been operating with a ROKU device and handset/remote for several years suddenly yesterday produced "no signal" on the tv screen as soon as I turn the TV on. Black screen , floating "no signal".
The Visio TV was mfg Feb. 2011 Model E42oVA.Serial # LTLPICAM 0600049.
The Roku Express 4K+ is SN SO7P428U1MAC
Please help. What can I do to make the TV operate with the new ROKU ?
