You'll get a good idea; I'm sure.

Since this question is almost a year old, I don't know if you have fixed the problem or thrown the TV in the rubbish bin, but looks like you're still waiting for a response. If so, here is my answer. It could be that these TV's have a back-up battery that discharges if left unplugged for some time and might reactivate the system once fully charged. It could be an environmental factor too. Maybe room temperature is too high that makes the TV shut down to avoid damaging the components. Is the TV near a fireplace or heater? There are Panasonic customer support centres, you should email them and ask, but, I would recommend you make a clear and concise explanation what exactly do you mean by the words you wrote here. Sure, I understand that when you unplug the TV, and then you plug it back on and it does not cut, cut? What do you mean by cut? Are you trying to say it doesn't work and that the pilot light doesn't come on until a week later? You don't even explain how long you had the TV unplugged. did you unplug and then plugged it right away, or did you unplug it and then plugged it a few months later? whatever it is, I suspect this TV must have a back-up capacitor as a battery. Or it could be that some damage has been done during an electrical storm, but I doubt it. Best ting you can do is leave it connected and observe if it repeats the same problem. If it does after a short disconnect then reconnect of the plug, it may require an expert check-up by an authorized TV repairmen, because this is really an unusual occurrence. Hope your problem will be sorted, or has it? It's almost a year now.

CRT screens use a vacuum tubes for displaying purposes. These tubes warn off through time and use, with symptoms like colours fading out, late responce on start and even quit doing what they suppose to do.
My solution is to replace the warn tube with a new one,if you really want to keep this screen properly functional, but this could get to much trouble and cost maybe.

It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

If i remember correctly ten blinks means a high voltage error.
The only thing you could try is unplugging the power cord then plug it back in and try turning on the tv. If it still won't turn on try unplugging the power cord for five hours or longer and try again. If it still won't turn on it would be best to find a local repair shop that works on sony tv's and have them repair it for you.

Best bet would be to unplug it completely and let it sit for about five minutes, plug it back in and turn it on, if it's still flickering there's more than likely something wrong with the backlight or the power supply. All Insignia TV's carry a 2 year manufactures warranty, so if it's less than two years old just take it to a Best Buy and have it serviced. It'll be gone for a few weeks, but either issue is an expensive fix.

That sucks about your tv. Mine just turned 3 years old. Never had a problem with it. But you seriously can't expect wal-mart to take back and exchange a 3 year old tv. Come on. That would be stupid for walmart to do. Even RCA prolly dosent do more than a 1 year warranty. Unless you purchased the warranty from walmart, it will be cheaper to just get a 19 inch lcd tv now. Cheapest I see them on sale for is only $99.99

sounds like the flyback is out. Thats a common issue with that Model. You can get a replacement flyback at the following link.
