The number of times it blinks is a code as to what the problem is. Go to the Panasonic web site and enter the model number etc. and it should tell you some where what the blinks mean. Different TV Manufacture's have different code blinks. Or you might get through by phone and talk to a tech. Then you will know what to do fron there.

SOURCE: TV power light blinks 7 times but it won't turn on

Most people call this "The blinking light of death".(part went bad)
Your TV when into protection mode to prevent further damage.
The repair shop may cost over $100 for someone just to look at it.
Or if you know someone with electronic repair knowledge, they have a service manual at nodevice.com
Most replacement parts you can get a shopjimmy.com ( go there to just to get an idea of what the parts costs).
Good Luck

Acer Aspire 5633WLMi does not work at all,even if i switch it on,it does not show any sign of starting up,it does not even blinking,what can i do?

Maybe last night when you were using it you were on your battery power because the power cord is bad. Does the Power Adapter portion of the power cord show any light when you plug it in the way before you plug it into the laptop?

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Remove the Battery, then remove the cover that houses the memory on the bottom of the laptop then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
