Have a pioneer PDP 5030HD w accompanying pdp r03u receiver that is no longer working. When I power it on the monitors light turns green for few seconds then starts blinking red. Blinks red 4 or 5 times then stops for few secs and then does it again repeatedly same tempo and cycle. No picture/sound or error msg ever comes up. The receiver is continuously on with green light and no flashing. Checked wiring and tried resetting to no avail. Any ideas of what it could be. Ty.
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.
