Sounds like main board fault. 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.

Where can I sell a pioneer pdp 5070pu plasma tv for parts?
HI, the best way to do this is to disassemble the set and post all the individual internal parts like the power board and main PCB logic and v boards, on line on a e-bay type of sale forum. this way, you can make more money. if you post the entire plasma screen with the crack as is, you will not get many hits. is will be assumed that it is damage goods.
Breaking this set down and, posting the internal circuitry piece by piece will make you more money in this case. The power supply board will sale for at least 289.00. and the main logic(PCB) will sale for 300 to 350. i would go this route to maximizes your gain.
