TV Repair Questions? Ask a TV Technician for Answers ASAP
Hello and sorry to hear you're having trouble,
you should be able to set your extender to an emulator/clone mode, so it will pass on the edid traits of the monitor to the source device, without needing any extra programming.
If you can let me know the model number of your tv though I'll see what other detail data we may be able to provide for you.
Thank you for your patience,
unfortunately I've not been able to locate any edid info for this specific model.
So long as you hook everything up and power on in a certain sequence (tv first, then extenders, then source device like av receiver) it should clone the edid info from the tv automatically.
