Disconnect the TV from the mains power and wait a little bit.Then connect it again and press the power button using remote control to power ON the TV. If that does not cure it then it could be a software problem - try this;1.Press menu2.Go to settings then go to other settings3.Find where it says Software upgrade Press OK4.Change automatic scanning to disabled and you should not have this problem anymore

How can I change the settings if it wont turn on? I have disconnected it how long shall I leave it unplugged?

Expert:  Plumbers_Mate replied 1 year ago.
At least 5 minutes with the plug out
Customer: replied 1 year ago.

If that doesn't work and the tv wont turn on what do I do then? I hope the first option works.

Expert:  Plumbers_Mate replied 1 year ago.
There are two ways to get your television out of standby, either cycle the power at the mains or press and hold the standby button on the television itself for 8 seconds until the red light goes out, then release and try turning on about 5 seconds or more later.According to Toshiba, the fault is due to the automatic update for the over air firmware - this is locking the televisions up and they are refusing to come out of standby.
Customer: replied 1 year ago.

Is the standby button on the front of the tv? Does Toshiba say that the tv will come out of standby?

Customer: replied 1 year ago.

I have just plugged it back in after about 10 mins and its still flashing. My standby button on the front of the tv doesn't seem to be able to push it. I am getting frustrated now.

Expert:  Plumbers_Mate replied 1 year ago.
Is that the button or the light?
Customer: replied 1 year ago.

It is where the light is flashing yes on the front. Where is the standby button on the tv?

Customer: replied 1 year ago.

I have had it unplugged for 30 minutes and put it back in and still flashing and not responding. I don't know where the standby button is?

Expert:  Plumbers_Mate replied 1 year ago.
Usually a row of buttons underneath where the lights are
Customer: replied 1 year ago.

There are no buttons underneath where the light is flashing.

OK you have already done the initial checks your problem is the mainboard is bad, it will need to be replaced now if the set is out of warranty the only options left open to you is to carry the work out yourself I will help and support you with that throughout OR call in a technician, now just so you understand the work involves replacing the mainboard you follow a procedure I will pass on to you, the mainboard is a plug in board no soldering or anything like that
Let me know if you can do this

Where do I get a new mainboard? I can try and do it myself. The tv is only 19months old. I got it as a gift for my phone contract so I don't think it has a warranty.

Expert:  info tech replied 1 year ago.
It may be an idea to pursue warranty as there is a european directive that says all electronic product should have a TWO year warranty so contact toshiba via the website and find out first before we move on Let me knowAnthony
Expert:  info tech replied 1 year ago.
If that falls flat we will move on with getting a mainboard
Customer: replied 1 year ago.

I think it could be best just to jump ahead and get the main board. How much do they cost?

Expert:  info tech replied 1 year ago.
You need to get the back off the set, locate the main-board thats the one with all the AV connectors on, unplug and unscrew the board from the chassis, remove the board ,carefully examine the board for its part number usually found on a sticky label on the board or etched on the board, (you may need to go through a few codes before you find the right number)when you get the part-number try www.flattvparts.co.uk first, if they don't have it google the part-number to locate a supplier, its the reverse to fit plug in and switch on TV (plug and play)
If you have any problems take a photo of the inside of the set and upload using the paperclip on your toolbar I will put markers on for you
Let me know if you need more info
