This is usually known as the ss board on your tv. This board carries lethal voltages in excess of 400Volts. You should unplug your tv from the outlet and allow the capacitors to discharge completely before attempting to replace this board. More often than not this code represents this faulty board. However, it can also be the logic board which is known as the D board. This is a very simple process and you can do this on your own and save lots of money. The cheapest route is buying boards on ebay. Make sure that you purchase from somebody with outstanding feedback.

I do agree with the tech but if the green led don't come on and the 7-blink error code is still there. check the connector from the logic board that will be the board under the small signal baord. The small signal board have the AV input on it. Check the connector from the logic board to the power supply there should be one connectore btween those 2 boards. On the power supply side second pin from the left it will say Vs_On if the set has 0 volts the proble is the SSB or the logic board. how to determain that is to Use 2 Jumpers to short J8003 & J8004 on the left edge of the PSU (see figure below).
Use 1 Jumper to short CN2012 on the lower left part of the Logic PCB (this will supply a 100% White signal to the Display).
Plug in the AC to the PSU thru CN8001.
If PDP panel operates with White field screen then problem may be the SSB.
SOURCE: red blinking light
The red light blibking 6 times indicates that the power supply board has a defective or damaged area. I know this because i had the same problem...bought a damaged tv for parts and replaced the power supply board as the tv would not turn on...wokrs like a charm now.

Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.
SOURCE: tv won't turn on. blinking red light in lower left corner
unplug the television...wait 10 seconds and then plug back in....if you listen carefully after 5-10 seconds you will hear a click sound (the same sound that you hear when you turn on or off) ...once you have heard it, turn the TV on again using the remote. Do not turn on until you hear the click. If this does not work, try again but turn the TV on again before you hear the click. I dont know why it happens but it is as if the TV gets confused as to whether its supposed to be on or off. Most of the time, the solution is to turn it on after the click so I would always try that first.
