Tv set switches off by itself after 5 minutes

The tv set starts up and works normaly,but after 5 minutes more or less switches off.If I turn it on again right after,it runs for almost the same time before and switches off again.I've checked for cold solders,but I've not found
anything wrong.Could you tell the possible causes for this malfunction?
I appreciate any help I get.

    Thanks Doctor video for your tip.The tv set now presents a new malfuction which is:as soon as it starts turns off and the flyback

    transformer is arcing near the HOT.I think the flyback has a defectiveness ,that's almost 100% sure. I decided to replace it and see what happens.I've already ordered it and I'm waiting for it.If that solves the problem,I'll let you know.

    .







    Thanks!

My Audiosonic td2401 keeps turning itself off, have checked the internal clock and timer, sleep mode is set to off, any other advice on keeping it running for more than 5 hours before it turns itself


HI. If you are 100% sure that no timer is active, then I guess it is a thermal problem in the TV. There can be bad solderings, mostly in the horiz., or vertical powerstages, causing the TV to shut down after 5 hours. At least, this time should be different if the ambient t° from the set is higher or lower.
If the "turn off" time is always exactly 300 minutes, no second more or less, then there might still be a processor problem in the TV. Not easy to find. Also, these replacement micro-processors contain a
pre-programmed booting section where all characteristics and alignment data from your set are stored as a factory setting....
Huge problem, which can only be solved by an Audiosonic service center. Good luck.

Child lock came on by itself on apex pf2720


Apex TVs have parental locks that allow you to block certain programs based on
their rating. When this feature is no longer needed and you want your TV to display all programming no matter its rating, you must unlock your TV. Unlocking your Apex TV is done completely from your remote control and does not require any tools. The process takes less than 5 minutes.
• Press the "Menu" button on the remote control and use the arrow buttons to scroll down to the "Parental Guide" option, then press the "Enter" button.
Type in the default parental code "6688" if you have not set your own code. If you have set your own code, type it in. If you set your own code and forgot it, override it by using "6688."
Use the arrow keys to switch the parental lock to "OFF." This allows all programs to be viewed no matter the rating. Press the "Exit" button on the remote and start watching all your channels.

Hello

Just reset your tv to factory settings. By doing this all the settings will be set to its orginal factory mode, and you have to reset all the settings including V-Chip settngs. To set it to factory settings do the following.

Switch off the TV wiith its front panel power ON-OFF switch and wait for about 5 minutes.

1 Press POWER to turn on the TV.

2 Hold down RESET on the remote control.

3 Press TV POWER on the TV. (The TV will turn itself off, then back

on.)
4 Release RESET.
OK.

My tv keeps switching off after about 20 minutes after initial starting. if tv is switched on immediately, then it works for less than 5 minutes before switching off. model: power vision.


I do not knowtis make , but this type of fault is sometimes due to dry joints in the flyback circuit or power supply try resoldering all pins on flyback transformer and chopper transformer, also cheek that the ht voltage is as the makers state. Waring unplug from mains before removing back and discharge ht resiour capacitor before starting repair

TV Turning on and off by its self


You have problems with a condenser that allow the power supply to maintan an acceptable level of voltage in order to keep the TV on. take to a tech to be fixed. unfortunatelly, this problem needs a tech to take measures in the circuitry to find the component that causes the problem.

It takes 5 to 7 minutes to turn on my Magnavox HD TV


IFyou feel confident and can locate switch mode power supply with back removed.
Try warming switchmode power supply before turning TV on.
If TV turns on normaly then there are some small capcitors that are a common cause of this fault.
Otherwise look for DRY or CRACKED solder jointson PCB
BUT DON'T do any of the above if your are not confident send it to a TV repaiman.

Sound Fades, then TV shuts off then continues to recycle on & off


Sometims several capacitors start going bad giving you the audio problem, but I don't remember the set turning itself off. That could be a secondary problem around the flyback transformer which may have a bad solder connection. I would check that first. Otherwise, I would be tempted to go with HDTV.
