This points to the Y-SUS circuit (left-hand side PCB).

If you aren't technical then it needs to be taken for service.

Continuous blinks of standby light indicates a fault in the IIC data bus. The main board is likely to be faulty. If you wish to know more Check this link.

I have a pioneer pdp-r05XE, on the plasma, the light flashes green and red alternately whilst on the receiver it flashes green 6 times. I can't get the tv to turn on...


Unplug if you have not done so BOTH units from power for several minutes (any cable or satellite box also connected.

wait several minutes and restore power to all units which may allow them to reboot.

Cannot hurt and may help.

PDP 5030 blinking red light on monitor


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.

Plasma turened off and red light flases twice


Red flashing x2 = Panel power supply fault

It would be easier to replace the power board than attempt a repair at component level (dangerous voltages)
