2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.

I'd check your Panasonic user's manual, usually, there is a list of codes for "other" devices. There may also be a way to do an automatic upload of the Toshiba device's code if it is on and the right button on the Panasonic remote is pushed.

Are you using a component video connection (3 wires for the video, colored red, green, and blue)? It sounds as though you are, but correct me if you are using a different connection as the steps will be different. If so, ensure that they are all connected. You can also unplug one at a time while watching the picture. If the colors DON'T change when unplugging any individual wire, then check that wire from end to end looking for cuts/corrosion/etc... If necessary, replace the cable. Also make sure that they're plugged in to the right jacks, they should be color coded. NOTE: there is a red jack for the video AND for the audio. Check carefully that these aren't mixed up.

Normally the event that you saw is the power supply. Sometimes it can be a failure on one of the boards that caused the power supply to go in to protect, or be damaged.

You must consider that after about 40,000 to 50,000 hours most electronic devices reach their expected life. There is something called MTBF (mean time between failure). This spec for consumer products is evaluated at normal room temperature of about 72F. A warmer operating environment will reduce the expected MTBF.

As you stated your set is about 2.5 years old. This is before the average MTBF period. Your set must have maybe 25,000 hours at most. I would expect to have a few years more with it.

From my experience when a TV, or appliance, or moist any electronic device has about 5 years of age it should be at its end of life period. At this age of a device investing money to service it has risk something else can fail.

I have recently solved the same problem with my panasonic that was just 2years 2months old. I took off the back of the tv and brush off the dust as there was too much dust clogging the vents and fans at the back. The tv is now as good as new. Hope your luck is as good as mine. by the way i was having 11 blinks as well.

To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

This is usally a cause of capacitors that have lost their electrolytics. You can either replace them by desoldering them out yourself or replace the power supply board known as the smps. It stands for switch mode power supply. More than likely, you can find one rather cheap on ebay. This board has deadly voltages that can kill you. Make sure the set is unplugged for at least a few hours to allow the capacitors to fully discharge. If you are going to try to replace the caps, look for bulges in them. When a set does what yours is doing it's usally easy to find the defective filtering capacitors.
