BLUE POWER LIGHT

My pioneer 5020FD Kuro tv. when I plug power to the unit, a blue light blinks 8 times pause 2 sec. and blink 8 times repeating this and if i press power button it clicks red light and makes a clicking sound and goes back to the blue light blinking again, it did this once before and the picture came on fine until i turned it off and now it just blink the blue code.

It looks like your power module is on the blink. Do you get any picture?

Fuel or ignition problem? Right after it dies, check for spark at a plug. A bad coil will often work till it's warmed up, then fail. If you still have ignition spark after it dies, or if it starts right up again, then it's something else.
Check the fuel pressure to make sure it's at proper pressure. Also scan the computer for any trouble codes that are related. It's easy on your car if you understand how the flashing light translates to two-digit number codes. Use a wire or paperclip to bridge terminals A and B of the diagnostic test connector protruding out from bottom of dash. It's a 12 pin connector. A and B are the two upper right terminals on it. Now turn key on and the check engine light will begin blinking the codes. Code 12 is diagnostic mode-one blink, pause, pause,blink, pause blink. See? 22 would be blink, pause, blink, pause, pause, blink, pause, blink. See? 33 would be three blinks, short pause and then 3 rapid blinks. (I"m going blink crazy!) Well, get the codes-they are two digit codes, and will keep repeating, lower numbers first and in succession, over and over while in diagnostic mode. Maybe an idle sensor fault will show up.
Good luck.

is it blinking constantly > or is it a number of blinks then a pause...count the blinks before the pause ..this is a repair code for your tv

Please count light flashing again. Light flash time is "0.3 Sec" and there would be pause (light Off time) for "3 Sec". Start counting after pause to next pause.

how many times does it blink pause then blink again?
