Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, would the Onkyo HT-R290 work as expected in radio mode (AM and FM) ?
Have you considered / tried a RESET of the Onkyo HT-R290 ?
Either a firmware glitch or an internal hardware issue.
Please post back results / observations of the above once the RESET has been tried.
A reset of the Onkyo would have no effect on the TV's performance particularly of its sound.
Or is there a cable box or satellite receiver feeding the Onkyo?
If yes and connected by HDMI, is the Onkyo's Audio TV Out set to On?
And after the RESET, would AM and/or FM now work?
A reset is both a test and a try of a fix.
That it was not corrective would point to a most likely possibility that the Onkyo has an internal hardware issue.
Have you tried connecting the Sony DVD player directly to the TV?
That it would not work in AM or FM would make it doubtful that it would work with other modes.
What is the model number of the Sony DVD player please?
Appreciate the additional information.
Let's complete the picture; how was the Sony BDP-N460 originally connected to the Onkyo HT-R290 using what kind of cable(s) please? How is it directly connected to the TV now? And how is the Onkyo HT-R290 connected to the TV?
That the Onkyo still fails to have sound even in just AM or FM would point to itself as faulty. This is specially true since a RESET was not corrective. It would then require repairs or replacement.
For the moment, the Sony DVD player would have to be connected directly to the TV and the TV speakers used for the sound.
Please post back how you would want to approach this and/or should additional information be needed.
