Hi and welcome to JustAnswer; an independent site with members providing product information, repair tips and technical assistance as a form of paid Q & A service.

Technician: Louie, Technician replied 4 months ago

Initially, is the TV directly connected to an antenna or cable feed?
Or is there a cable box or even a satellite receiver?
Or some other device/s?

theTV is fed by a DISH SAT receiver
Technician: Louie, Technician replied 4 months ago

Please re-confirm and post back with the complete model number of the "...DISH SAT receiver..."

Additionally, describe how the DISH SAT receiver is connected to the Emerson TV using what kind of cable(s).

the DISH SAT mod # VIP222K is supplied with standard coax cables but this is a master unit supplys a another unit with radio service in another room
Technician: Louie, Technician replied 4 months ago

Appreciate the additional information.

Have you tried / can you please try connecting the ViP22k's red & white AUDIO OUT jacks using a pair of RCA-to-RCA cables to the RTS7010B's AUX IN R/L jacks?

it did not change any thing
Technician: Louie, Technician replied 4 months ago

A final test...

RTS7010B turned on, set to AUX and VOL ▲ raised, disconnect the red & white plugs connected to the ViP22k's red & white AUDIO OUT jacks.

Lightly touch only the tips of these pulled out plugs.

There should be a thump/humming sound from the RTS7010B's speakers.

no response
Technician: Louie, Technician replied 4 months ago

Based on the above, it would then be indicative of an internal hardware issue with the RTS7010B's circuitry.

Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiarity with a multi-meter and even a soldering iron?

I'm a retired electrician & have built a good deal of kits so I have all the needed equipment
Technician: Louie, Technician replied 4 months ago

Great on the DIY!
When able, please post back with clear pictures of the RTS7010B's circuitry particularly the power supply section. Of interest would be the electrolytic/filter capacitors. Click HERE.
