Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

I had the same problem and fixed with a great online tutorial. Just replace 3 capacitors available at Radioshack onthe the board. 2662, 2663, 2664 1 is a 1000uf the others are 100uf. Max Volts need to be over 25. It worked great, check http://dynamicorange.com/2008/06/25/fixing-a-plasma-tv/

SOURCE: PINK SCREEN ON DAEWOO PLASMA TV

Sounds like your panel might be going out or a faulty video card. This is the first time I have heard of a solid pink screen on a plasma. Usually this happens on LCDs, though they sometimes go white and stay white, which does signal a bad panel. tv needs repair

SOURCE: The screen on my 4 yr old 42 inch LG plasma keeps

I believe that you are experiencing an intermittent problem with what's called your florescent lamp ballast. The best thing is that it can be repaired/fix. There should be a LG repair shop in your area. Cheaper to bring it in than have a service tech come to your residence.
Should be between $200 to $300 for a repair.

SOURCE: THE MENU KEEPS POPPING UP ON THE SCREEN CONTINOUSLY ON MY 42 INCH

I had an LG 37" LCD that did this to me. Turned out to be bad solder joints on the side button board. Just reflowed and it starting working fine.

But now that I think about, I had another set do the same thing, only it wasn't the button board. I had to upgrade the TV's firmware via the USB service port. Just needed a USB flash drive and downloaded the firmware from the mfg's website. There were easy to follow instructions there too!
