What does pioneer plasma PDP-LX 2 red blink code mean?

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.

After replacing the power supply board, it is necessary and a must to adjust its Va & Vs voltages. These details will be there on its panel label. If you wish to get some details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up older posts. Without adjusting these voltages properly, might make the Plasma Display defective.

Pioneer has this to say about the issue:

"On the models listed below, Engineering has determined this to be part of the normal operation, if the unit will power on.
If the unit does not power on, service may be required on the set.
Please contact our Plasma support at 1-800-421-1625.""
Elite models:

Pioneer models:
PDP-4270HD, PDP-5070HD, and PDP-6070HD

Good Luck

That is an error code that likely means power supply issue and based on brand not likely to be a do it yourself fix. Consider having a authorized Pioneer service center look at it and get an estimate.

Visit the site named 'Electro-help' for more details. Check this link and select the site named above. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. Some times, the ads attached with each posts, both at the right and bottom, might help you to find the availability of spare parts. There are more than 730 posts to different brand TVs now.
Blinking codes to Pioneer Plasma TVs have been described in detail there.

Any luck with this? I really need this information as well.

OK Its your power supply and it can be fixd for free due to a recall.

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.

The 3 blinks ( i assume they're blinking in red) means a scan assy problem. Check the scan A & B boards and the Y drive board. Something is shorted and loading down the Vscan voltage of the power supply.
