Sanyo MTS/Stereo/SAP/DBC Tv picture flashes and makes noise

Just got a tv from my neighbor. It was working fine and then my little guy was watching cartoons and all of a sudden the picture started flashing and at the same time the tv makes a noise. I have universal remote and I'm wondering if somehow this is interfering with the tv or did I buy a dud?

SOURCE: On Timer light flashing on my TV

If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. good luck!

It looks to me that your tv is starting up and then shutdown. I have suspect that your tv have a high voltage shutdown. Check your B+ voltage, if not correct rectify it. If it sound like gibridge to , then seek professional help. good luck

SOURCE: TV wont power on, clicking noise and flashing standby led

Sounds pretty bad to me, I had a computer monitor that did a similar thing when plugged in after blowing, it's not a good thing. I didn't even bother to mess with it. You may have to replace the whole power board or at least have a whole handful of pieces to re-solder. It most likely isn't worth it unless your other tv's are under 30" and you don't have a lot of money ;)

SOURCE: turning the sap off using my universal remote

If there are any menu setting buttons on the t.v. itself then I would try using them to find the sap setting.

SOURCE: TV will not turn on

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

No sound,but good pic.everything else works fine.(toshiba 57hx94)


hello,

• Check the antenna/cable connections (see Chapter 2).

• The station may have broadcast difficulties. Try another channel.

• The sound may be muted. Press VOLUME.

• If you hear no sound, try setting the MTS feature to STEREO mode (page 81).

• Make sure the SPEAKERS function in the AUDIO SETUP menu is set correctly (page 83).

• If you are not receiving a second audio program from a known SAP source, make sure the MTS feature is

set to SAP mode (page 81).

• If you hear audio that seems "incorrect" for the program you are watching (such as music or a foreign

language), the SAP mode may be on. Set the MTS feature to STEREO mode (page 81).

• When using an external audio amplifier, if you connect the amplifier to the VAR. AUDIO OUT jacks, the
volume of the TV and amplifier must be set above 0 or you will not hear any sound (page 20).

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.

My wife was hitting buttons on our satellite remote and the audio no longer works. She thinks the tv is the problem. I have tried all of the Satellite volume menus and am unable to get the sound back on.


TV: check for SAP or MTS features, set them to STEREO. Also, verify that the TV Speakers are set to ON.

Cable Box: If the box has volume controls, make the volume is turned up. Also, check for the SAP or MTS feature. Again, set this to STEREO.

I hope this was helpful, best wishes.

No sound on some channels, other channels fine


Your SAP/MTS function is most likely turned on. This feature has 3 modes: Stereo, Mono and SAP. Stereo and Mono are easy to understand, it's the SAP that can get you. SAP stands for Second Audio Production. It is used to provide weather, information or an additional language translation of a program. Some broadcasters simply transmit the mono audio over the SAP audio channel when the are not using it for other purposes. Other broadcasters simply do not use it, which does not give you any audio. Look on your remote for a SAP or MTS button. If you do not see one, look in your TV user menu for this feature. If you are using a cable box, look in the audio menu of the cable box. You are looking for something set to SAP... just change it to STEREO. I hope this was helpful.
