Pdp-6010fd blue light blinks 12 times

Brand of TV?

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 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.

it could be due to a leaky capacitor not holding it's charge , check them but earth the board after removing mains plug.

Hello
The set can be set right by repair. You must have through knoledge in electronics to do work with set. especially, plasma displays will have very complicated circuits. It Sustain-Boards suld be trouble shooted.

You need a firmware upgrade that has to be done by a tech onsite. I've done many of them. 12 Blue blinks is a TVGuide download trouble and doesn't hurt the set but a firmware update should solve it. If it occurs again after that you need the Main Assy replaced but make sure the firmware is updated on that also.
Problem will go away
Hope this helps

looks like 12 blue blinks is a communication with the Digital tuner error. pioneer had a software upgrade/fix for this in some cases, others might need a new digital tuner pcb. I would unplug all power, wait 5 min, plug in (wait1 min) and try it again. If it is software, it should hopefully work. Make sure you pull your cable card if you have one. If it still won't turn on, you probably need the digital tuner board = $200-500 repair. Pioneer is usually very helpful, I'm really surprised they didn't help at all.. They'll want model #, serial # and date of purchase.
