I have a Panasonic plasma TV model# TH-42PX75U --- here is a link to Panasonic web site for this model http://www2.panasonic.com/consumer-electronics/support/Televisions/VIERA-Plasma-HDTVs/Operating-Instructions/model.TH-42PX75U.O#ts --- While I was watching TV it randomly shut off and now when I try to turn it on I have to hold the power button down for a few seconds then the TV comes of for about one second and automatically turns off again. The red light blinks in increments of 12 then pauses then blinks 12 times again and again... I have tried unplugging the TV over night and no success. Please Help.

Unfortunately your going to have to have it serviced by an Authorized Panasonic Dealer. Independent shops will not be authorized to order parts without the consent of Panasonic. They are rough to deal with.

Check the site linked below, and compare the screen shots. It has many kind of defective screen-shots to plasma displays. Compare them to that of yours, and make sure about the faulty board or others. http://electronicshelponline.blogspot.com/

well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

The tv can be fix about half of the price of a new one.This tv brand and model known to have alot of power supply board issues.The price about between $500-$550 Tech. replaced tv with a new refurbish power supply board replacement or troubleshooting and by replacing components parts on the power supply board.
This could be a reception problem of the cable transmission or the cable box if used. Are you using cable or SAT box. Tv goes to blue screen if signal is weak automatically.
