If its an older television then that is fairly common, it also happens on newer models. The process is literally just like you say, warming up. It takes a moment to get them to active operating temperature. Alternatively you could just leave the television on, a television of that age actually uses more power when you turn it on than if you were to just leave it on all day.
I had the exact same problem yesterday. It took me 1 hour and 45 minutes to find a solution. Here is the solution: It is not a stuck button or the television being 'posessed' that is resulting in the menu cycling. It is the fact that the television is in the DEMO mode. I was able to read the manual for this television online at the Toshiba website. On page 30 it states 'To stop the DEMO mode press 'recall', ''exit', or 'power'. Unfortunately the 'recall', and 'exit' button are on the original remote which I no longer have. The power button on my model is broken. I use the cable box to 'turn on the television'. In reality, the TV is never off, it is just showing a black screen when the cable box and DVD player is off. I suspect this defect in the power button has occured on other TV's experiencing this problem. I was able to push the broken power button to the inside and side of the television casing exposing a round circle that the power button pushes when the power button is not broken. I pushed this small circle to turn the television off. After about 5 seconds I pushed the button again and the television went on without the annoying menu popping up. Just unplugging the television and plugging the television back in does not work. You need to be able to push the power button, or one of the other 2 buttons on the remote previously mentioned. Also on page 30 it explains how to activate the DEMO mode. It's not too hard to accidentally do, especially when you have kids pushing buttons haphazardly. I hope this helps someone outthere in cyberspace! Kevin
i dont know about a code but i would check my 5 volt standby power supply voltage ,and depending on tv check all standby voltages with set pluged in only .if stand by voltages is good check for horiz drive at base of driver trans when you press the power button
that it is simple to do go in the menu and locate the timer menu and then push the buton many time till you see on the screec as your timer is off
ex first time you will see 120 min then push buton after that you will see 60 min , and then 30 min, then 15 min. then you will see off
Try this: turn on your tv.
Push and hold code search button until the led light stand.
Release him push and release the device button( Tv,Dvd,Vcr),now you got to push and release the power button until the tv turn off now you push and release the enter button and the code are now on the remote memory.Good luck
The first thing to check is the push button assembly maybe the volume down button has been pushed in too hard/far and is always making contact,sometimes when we clean the face of the tube water drips down in thru the edge of the frame in the buttonts,corrosion sets in and creates a short,if you are familiar with tv service you can chech the buttons thru the inside to make sure they are not pushed in but if you are not famliar be safe and call for assistance froma servicer.
