Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems. Offhand the blue blinking light is a code used by Pioneer to tell a tech what may be wrong with the set. Can you please count the number of blinks between pauses (for example: 12 blinks, pause, 12 blinks, pause) and let me know what you get?
Thank you for the reply. The 12 blink code is a communication error between the Power Board and the Mainboard. This is preventing the set from powering up, and in many cases requires hardware replacement to fix the issue.
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 3 times, and please let me know what happens.

Thank you for the reply. The 12 blink code is a communication error between the Power Board and the Mainboard. This is preventing the set from powering up, and requires hardware repairs to the set. If you bring this to a shop, you're looking at an average cost of between $350-$450 parts and labor to repair and can use the link below to locate a shop in your area:
Alternatively, if you're a DIY type and looking to repair the set yourself, let me know what experience you have and we can proceed accordingly.
Other than that, I'm sorry for the bad news and wish there were a quick fix.
Okay, not sure what you're saying here. So you want to repair the set yourself, and have a multi-meter and the ability to test voltages?
No, not me- the site sends that offer. I don't use the phone call feature however.
