Facing TV Problems? Ask a TV Technician.
Hi Peter and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the Akai TV.
And is there sound when any other source/input is used?
Is this a fresh/new install? ...or has the Akai and Panasonic been working together before and this no-sound issue just recent?
Appreciate the additional information Peter.
Have you re-checked and/or replaced the yellow + red & white RCA-to-RCA cables?
...and verified that these are connected to the Panasonic's AV OUT jacks to the Akai's CVBS + R & L IN?
