This is caused by a faulty part inside your tv, not a bad setting.
You need to take the cover of the tv and start testing components: first of all you need to determine is this cycle is caused by an unstable control processor or the power source itself has a faulty part - you do that by determining from where the shutdown command is coming. If it's coming from the processor then it is the faulty part.
You need good knowledge of electronics to do that, if you don't posses it then it's time for an repairman.

Medion lcd hd 31.5 inch tv won't turn on


I bought one also from ALDI for my son's Xbox 360, it is only 3 weeks in use and I have the same problem. The red led is on, indicating that it is in standby mode and recieving power but I can't turn it on either by pressing the power on button on the TV it's self or the on button on the remote. This started happening a few days ago and it's totally random. I found that if you unplug the TV from the power point or alternatively switch off the power point for a minute, than power it on again it will "WORK AGAIN" for a while. Like I said it is random, eventually it will return to the not being able to be switched on state at which time you will have to repeat the process. So thus, this is not really a solution. I am about to return the TV for a refund, and it's a shame because otherwise it's not too bad. and looks OK too.

LG TV KEEPS TURNING OFF


Kindly do not keep attempting to turn it on, as you are likely to spoil some other boards/parts/components of the TV. Look for any loose contacts in power out let, RC jack, cable and socket. In order to ensure, it is not caused by the input device, connect a DVD player
and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

My tv keeps switching itself off


Check all the main filter capacitors in the main power supply regulator board. Replace them all will be best.

Have to try a defferent monitor to diagonais a problem but if its showing all your booting process after switching on nothing wrong with your monitor,but if keeps on restarting itself after boot up process ,I'd say that your system error corrupted. Need to reload your sytem.

Blinking power light


The TV has developed a fault where the start up procedure cannot be carried out & therefore the TV switches itself back off. You would need to remove the back of the TV & check if there are voltages going to your backlights (24v), are there all the other voltage rails present at start up eg 15v, 5v etc. Check the power supply to see if any of the capacitors are showing signs of stress such as a bulging on the top. If you do not have a multi meter to check voltages or feel comfortable to do this, then it would be best to contact a repair service centre.

LG TV Turns itself off


Sounds like it could be a poor connection in the power plug or a ' dry joint ' on the power board, if it's the latter, it will respond to light thumping at the side of the tv. If that's the case it needs resoldering by a technician..
good luck !
