Power on light flashing red
Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Why won't it start?
Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

H1005 error
I played with going to another HDMI outlet and then back to the original and it seems to quickly reset itself and the message dissappeared!
Blinks 7 times
7 blinks to Panasonic TVs indicates that there is some fault with its Driver SOS 2 SU / SD/ or SS boards. You must have sound knoledge in electronics to work out with this TV. I recently came across a site named electro-help, which have so many details to repair different brand of TVs. It includes Panasonic's faults too. [electronicshelponline.blogspot] is the search item to vet this site name.
My 50" panasonic only blinks 10 times but
Hello,
The main cause of this power up problem are bad capacitors on your power if the capacitor is bad. See more bad capacitor image
Now, if your LCD set is still under warranty I would suggest to use it and let the professionals handle the problem for you. But for the rest of the Samsung LCD TV owners that their warranty had expired and want to save some money, this would be the best route. Mind me, when I fixed my power supply I didn't have any previous experience on desoldering and soldering capacitors on a power supply board. It was a good experience after all is said and done.
Now lets talk about the specs, capacitors hold 3 important value:
1. The capacitance measured in uF(micro farads) (ex. 2200uF), 2. Voltage (ex. 10v), 3. Temperature (ex. 105°C)
I hope that this will help to solve the problem and do take care because it contains high voltages...
Turn on tv with remote
The power supply board is the cause,because of those parts call capacitors are dying of leakages of gases.U have tools,know basic electronic's and soldering?That the board,where the power a/c cord plug into it.Searches the power supply board for these dying leakages of gases capacitors,it alway bulges up on it tops or puff on it tops,replaced these dying capacitors,will power up ur tv normal again.Or tries websites like shopjimmy.com,Ebay,com to buy a refurbish power supply board for the replacement.
The picture is too large,
check and see if you have a zoom button on the TV remote
If your hooked to a cable box call the provider because some of the cable boxes have a setting that will cause this issue
What board should I change
Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
