Karl,

How many times is the POWER LED blinking? (Don't worry about the OPC LED).

1x = Bad inverters/lamps
2x = Bad Power Supply
3x = Bad Main Board

Either way, there isn't anything you can do to fix this, you need to contact Sharp to have your TV serviced.

Can't change from MONO to AUTO mode


Hello
Can't make sound from mono to auto is your problem I thinks and posts this solution.
Hit the "Menu" button and surf through, come to "Sound Adjust" window.
The settings allow you to change and adjust sound in your TV. There are Bass, Treble and Balance control to adjust to your individual taste.
To adjust them
1. Press Menu button.
2. Press UP or DOWN button to select the desired item.
3. Press => or 4. Press EXIT button when finished.
When adjusting the parameter of "Balance" control, always set it to mid position to get stereo sound from both speakers. If it is set to any extreme end, there will be no output from the speaker of that side, and will hear as mono.
If you press "0" [Zero] button, you can reset the sound settings to it Factory settings.
To select 'Streo mode;
1. Press "Menu" button.
2. Press UP or DOWN button to select MTS [Multi-channel Telivision Sound].
3. Press => or [The ON AIR arrowtells you if a broadcast is in stereo AND/OR contains the SAP.
Press "Exit" button when finished.

Keep the TV in stereo mode to get the best sound quality. The sound will work in stereo

mode even if a certain broadcast is in mono sound only.

Choose the mono setting to reduce excessive noise on a certain channel or broadcast.
Selecting SAP will allow you to hear an alternative soundtrack, if one is available.

How do I get my rca truflat tv to get out of mono?


Hello
Press the MTS on the remote control handset to select STEREO, MONO or SAP. All the options will be available only when the current TV channel is broadcasting that option. Channels will not always carry programes, that have all MTS options. If "STEREO" appears on the screen when you select a channel means stereo sound is available with current programme. You can hear sound from both speakers. If broadcast is not strong and clear, stereo sound will not be available. Press "MTS" button to change it to "Mono". This will eliminate the noise. If "MONO" appears on the screen when you select a channel, stereo effect will not be availabe, even though you have set it to stereo. If "SAP" appears when you select a channel 'Second Audio Programe' [SAP] broadcasting is available for that programme. Press the "MTS" button to 'SAP' and you can hear that programe in different language or some other kind of audio.

Auto muting on when on am/fm and no sounds come out. everything else is fine.


That's normal.

The Auto Muting mode mutes the audio output of the tuner if the station is not sufficciently strong to be accurately tuned. Otherwise you would hear all that interstation hash noise.

Press the FM Mode button to change it to Mono if you want to manually tune a hard-to-reach station. It will be in Mono.

Page 26:

AUTO MUTING
Normally select this.
When a program is broadcast in stereo, you will hear stereo sound; when in monaural, you will hear monaural sound.
This mode is also useful to suppress static noise between stations. The AUTO MUTING indicator lights up on the display.
