Hello The problem I have with my TV is that sometimes it switches itself into standby mode without me pressing any buttons on the remote, then when I switch it back on using the remote the screen flickers 2-3 times then it switches off again, this process is sometimed repeated upto 7-8 times before I get the TV to switch and stay on, sometimes it does it after I've switched on to begin watching telly and other times it happens after I've been watching for some time, its a really annoying problem and sometimes a hard reset (switch mains power off) is the only way to cure it, yet on other days the TV works faultlessly, is this a known fault or something new to you? I've had the TV since the beginning of the year.

To get your TV off standby mode, you can try the following steps:
Check the power source: Make sure that your TV is properly plugged into a working power outlet or surge protector.
Check the remote control: Press the power button on the remote control. Sometimes, the TV may be in standby mode due to a problem with the remote control. If the remote control is not working, try replacing the batteries or using a different remote.
Check the power button on the TV: If the TV does not turn on with the remote control, try pressing the power button on the TV itself.
Unplug and plug back in: Unplug the TV from the power source for at least 30 seconds and then plug it back in. This can reset the TV and may help to get it out of standby mode.
Check for a timer: Some TVs have a timer function that automatically puts the TV in standby mode after a certain amount of time. Check the TV settings to see if this feature is enabled.
If none of the above steps work, there may be an issue with the TV's hardware or software. In this case, it may be best to contact the manufacturer or a professional repair service for assistance.

Try pressing the small reset button on the back, it works, and you will not loose any stored information which caused the unit to go in the stand by mode.

or
Have you tried turning it off for an hour and then turning it back on. This happens to me quite often and leaving it off for a while ususally allows it to come back on. Also have you tried to press the TV/AV button on the remote as sometimes it switches to TV mode when its on standby and then standby won't work as its on TV mode and needs to go back on to AV mode. Basically just press the AV button on the digibox remote and then try standby.

or
if the batteries are removed and left for about 20 minutes before being replaced again, everything works as it should.
or
if any of the above suggestions does not work then you have to open the unit and on the main board of the tv there is a thin mini tube light like component called fuse you will have to replace that fuse .the fuse is very very cheap and you can easily get it at any electronics shop.and if still the unit does not work then there is a major fault in the power supply board and should be taken to the service center for diagnosing the fault that it is repairable or not.but i hope the above information provided will definately help you to solve your problem.

Try following the steps below.
Step 1
Press the power button once. If the TV does not turn on, observe the LED indicator, usually located on the TV's lower front panel. If the LED indicator turned off after you pressed the power button once, it is in standby mode. Press the power button once again to exit standby and turn on the TV.

Step 2
Observe the Standby light if the remote control will not work. If the Standby light stays on, the television is in Standby mode. Press the power button on the television, then try to use the remote.

Step 3
Turn the Energy Saving Switch off, then press the power button. The Energy Saving Switch is located on the rear or side panel on most Sony model TVs. Refer to your TV user manual for the exact location of the switch.

Your tv sounds fairly normal to me - there is a difference between a tv being switched off and being on standby. It is usual for a tv to need to be switched on manually and from there the remote would be able to switch it between on and standby.
Sometimes the "power" button of the remote only switches the set to standby and selecting a channel would switch it from standby...

Check its mechanism for fault.

Hello
The three digit Sky remote code for Beco TV are:

514 398 065

Four digit code is:

0125

1* Turn your TV and SkyHD box on and press tv on your remote control.

2* Hold down select and the red button together until the red light on your remote

control blinks twice (this is after about two seconds).

3* Press tv again.

4* Key in your TV's brand code. The light on your remote control blinks twice.

5* Press standby on your remote control.

If your TV switches off, press select.

The light on your remote control should blink twice.

If your TV does not switch off, press tv, then press standby.

Repeat the sequence of pressing tv then standby until the TV switches off,

then press select.

If the light blinks three times, your remote control has checked all the possible

settings for the code you used. Check you have the right code and start again

at step 1.

*6 Turn your TV back on and press the tv guide button on your remote control.

The TV Guide screen appears, meaning the remote control settings have
been reset.

I managed to find a local repair man who fixed the problem. He put in a new transformer.

have you tried changing the batteries just to elimate this problem

change them

sometimes if the batteries are low in electronic devies, they send a wek signal to its receiver (your tv),

your tv gets confused and then switches itself to standby

if you have changed the batteries and this problem still persists

it can only then be th PSU or power supply unit, take it to your local tv repair shop of mastercare somewhere like that, its going to be cheaper to get it repaired than replacing the whole tv

PSU'S generally 20 to 50 pounds depending on model

don't deo it yourself though unless you've got a capacitor discharger (or a nice 25KV will be on its way to your body)

hop this helps mate, let me know how you get on

Right i had this same problem for ages! i cannot explain why but when i uplugged my DVD player (which was flashing its light at the same time as the tv for some reason) the TV has worked fine.
