2980wxranger when its on for 30 min the rec ever channel sound like bleedover

This sounds like the either the output transistors breaking down or the electrolytic capacitors on that channel.
If not.
ELECTREPAIRUSA@ELECTREPAIRUSA or you can contact us at that address as we repair/renovate all items electronic and electrical old and new.

1. Press and hold down the ASSIGN A button (the light should be blinking) then (simultaneously) press the REC button above channel number 1. The light should blink when you do this.
2. Release the ASSIGN A and the REC button
3. Press the REC button above channel 1 (the light should be blinking by itself)
4. You should see the meters moving with in the display above Input A and Track 1 when you speak into the microphone.
5. Press the REWIND button twice until the display reads ABS 00.00.00.00
6. Press and hold the RECORD button and press the PLAY button. The REC light above channel one, the PLAY light and the RECORD light should become solid.
7. After recording press the STOP button.
8. Press the REWIND button twice until the display reads ABS 00.00.00.00
9. Press the PLAY button.

Check to see if your audio source is set to SAP. This stands for secondary audio program. For example, some stations broadcast english and spanish. Some stations broadcast english and nothing. If you are on a channel that broadcasts english and nothing, and you are SAP setting, you will hear nothing.

tv is on but no picture

Well... It consumes 240 watts of electrical power total so take the audio power specifications with a huge grain of salt, as no audio device puts out in audio power anywhere near what it consumes in electrical power. Heat produced is power consumed, too and nothing is 100% efficient.

In the specs below the only information useful for comparison is in the line I highlighted with >>> <<<<'s as it conforms the closest to the industry standard practice of using:

"X watts into 8 ohms (standard load) from 20 - 20000 hz plus or minus Y db at no more than .0Z% distortion"

The better amps specify vanishingly low distortion specs (0.0x% vs 0.x%) at the cost of being able to claim higher wattage. But they guarantee cleaner sound at the claimed levels.

JVC is being tricky with their choice of a 40 hz lower limit. THAT is the power hungry end of the spectrum. 20 hz is normally the lower limit stated.

"Output Power .............At Stereo operation
Front channels .............55 watts per channel, min. RMS, driven into 4 ohms at 1 kHz, with no more than 0.9 % total harmonic distortion. (IEC268-3/DIN) 30 watts per channel, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.9 % total harmonic distortion. (IEC268-3/DIN)

>>>>> 30 watts per channel, min. RMS, driven into 8 ohms, 40 Hz to 20 kHz, with no more than 0.8 % total harmonic distortion. <<<<<

At Surround operation
Front channels .............50 watts per channel, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.8 % total harmonic distortion.

Center channel .............50 watts, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.8 % total harmonic distortion.

Rear channel .................50 watts, min. RMS, driven into 8 ohms at 1kHz, with no more than 0.8 % total harmonic distortion."

Check the input channel is 3 or 4 if you are using an external receiver, satellite or cable. If it is set on 4 and the input receiver is 3 then you will have adjacent channel "bleedover". make sure the two units are set on the same channel.

if it is under warrantee then fix it.
sounds like a component is over heating, probably cost couple hundred (or more) to fix it, balance that with what you paid.

Their is no more you can do.
You need a professional.
Stop using the TV until it is repaired.
Call the manufacturer to find you nearest authorized service center.

Try uplugging the video for 20 mins
Plug back in again
Hold down the REC and the Channel Up buttons together.
The vidoe ahould then ask you to enter your pin.

The switch is contaminated. Pick up some electronic switch cleaner and spray into the switch. Move the switch back and forth a number of times and that should clear up the problem. Make sure that you get the cleaner that has a lubricant included.
