The main power supply regulator section circuit fault. Either it will be a separate board, or the part of 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. 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.

hi look for any swollen capacitors, also plasma's do suffer from poor solder joints on the power board, so check for any rings around the solder pads, test the voltages on the white connectors with a meter the voltages will be written along the connector,thanks

This is a power supply issue - found a company that has used power supplies, they sell them for $60.00. We recommend a professional install the board because the voltage needs to be adjusted after the install or you could damage something else. The high voltage in the set can KILL you soe be very careful. The web address for the PS board is plasmafix.com.

These 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 stage 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. Viewing it in "Mosaic" will make surf easy.
