Same problem I am having the same problem as the parent. My television turns off immediately after turning it on. I believe it is what you described as going into protection mode. Especially since I had been playing with the convergence just a week before that (trying to fix it, as it was WAY off). I'd be interested in knowing how to reset the protection mode, and get the convergence back to normal. I do have some very basic electronic skills.

Your set is going schizo. Try unplugging it for a while and pressing some reset button (if available) and see what happens.

It seems you have answered your own question, I have noted and archived it--for future use to help others.

I have the same problem. I'm guessing mine is broken and will need to be replaced. However i did read a possible solution on a site with slightly different instructions to the ones in the box that describes how to pair the two devices together.

turn both the nursery and parent units off.
turn on the parent unit.
hold menu for 5 secs until it beeps.
turn on the nursery unit.
the parent unit waits for the signal then pairs.

if the nursery unit just waits 20 seconds then beep beep beeps and turns off i guess yours is broken too. I think its probably the nursery unit has stopped transmitting.

they will replace or repair a unit that less than 12 months from date of purchase with a supporting receipt.

It Sounds like to me that there is something with in the Optical block causing the problem.
I would recommend a professional to look at it and confirm this.
Hope this helps,

Someone has put your Close Caption on in Text mode.....Just go into your menu and turn Close Caption OFF

Could be the parental control.  See Mark Z solution for power LCD blinks, put TV will not power up. Hold remote power switch down for 6 to 8 seconds to get out of parental control mode. 

Based on what I have read AKAI has reoccurring problems with power supply and bad DVD sound. The problem you have is caused by the DVD player trying to start. Never leave a disk in when you shut it off or you will have the same symptom you are describing.

although my situation was a bit different, part of msimeomix's solution still worked. after entering the password "3308," the screen went blank. i knew this parental code had worked but it would still not allow me to access the "setup" or "menu" options. i pressed "STOP" and then ejected the disc/turned the DVD player off. upon turning it back on and entering the password "3308" i was able to immediately press "PLAY" and it worked. enjoy the movie :]
