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?

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.

To all the user with this problem.

The TV is on protect mode. The clicking sound is the protection switch that keep turning the TV off to prevent further damage, this happens when a fault had been detected.

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

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

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

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 , startingthe flashing light.


If you are in situation one, then theTV 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.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


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

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.

Your SAP audio function is on. Look on your remote or in the TV menu for SAP or MTS. There are 3 settings, Mono, Stereo, and SAP... set it to Stereo. I hope this was helpful, best wishes.

I have a new Sanyo tv and cannot get sound on 6 channels! I originally received sound but suddenly left.


It sounds like your secondary audio (SAP) has gotten turned on. Look on your TV remote for a button that says MTS or Audio and press it until the screen says Stereo. If you are having difficulty locating how to turn off the secondary audio feel free to repost with the model # and Manufacturer (Sanyo) and we can try to help you further...

Good Luck....

I am not using cable or dish...what type of antenna should i use to get the most out of the digital conversion...and is the built in converter adequate or do i need converter box?


The specs for this TV shows it has ASTC and NTSC so you do not need a converter box.
Almost all the Digital channels are broadcasted in the UHF band.
When you scan in the channels the VHF numbers will still show but the actually signal will be in the UHF band.

Greetings de_on,

Per your owners manual I found you should have an option in your Audio menu labeled MTS. You should be able to adjust the MTS by selecting it and press the + key.

There should be three options under MTS: Stereo, Mono, Auto SAP. You would probably want to select Stereo as Auto SAP will engage the Second Audio Programing which will cause other sound problems.

Hope this helps.
