SOURCE: Pioneer PDP 5030 power supply problem

Ok here's how I manage solve the problem... Having the back removed opens the contacts on the interlock switch so I guess if it powers up in this state it senses the high voltages are exposed and for safety shuts down... After this the unit will not power up and the power led flashes red continuously as described before…
After some thought it occurred to me that there may not be a problem at all, just be a simple reset function for this condition… I managed to find an easy solution to this… Just call up the hidden engineer’s service menu – On 3rd generation Pioneer Plasmas it’s as follows > Power down the screen > Hold down the “Input” and “Vol +” buttons on the front > Power the screen up and the Service menu comes up on the screen > You don't need to change anything just simply power off and from then the screen should operate as normal…It did for me so I’m well happy now!!
I hope this information will help someone else one day – Good Luck!!…Rob UK…

It sounds like to me that either a capacitor blew up or the powersupply failed. Let me know the serial # and the other model # located on the back and i can assist you more. Possibly a driver IC on the ribbon cable going to the panel might have popped, which is about the size of a postage stamp and can be repaired fortunately, but it isn't cheap. If you do it wrong, the panel is ruined for good. If you do it correctly your set is fixed. Fortunately for you i know the boys over in O.T.S in Chicago which can assist me in helping you. Let me know if i can be of anymore help for you. I am located in Louisville, Ky. Thank you Jay

Very possible,but yet,this might be the manufacturer defect power supply which they will fix it for you free;but before we jump to this conclusion,you need to test it first:
-Unplug the power cords.
-Unplug the media video cable from the box to the tv.
-Check all the pins on the video cable are in place as well as the connectors both behind the TV and the media box.
-Reconnect the media box and TV with the video cable(DVI+VGA in one) and have at least a video component hook up to it(ex. dvd player/VCR or comcast box) be sure this video player is turn on and running,at the same time,be sure it is under the right video input.
If you have tried the above steps but still doesn't work,call 1-800-pioneer Tuesday-Thursday at7amPST and address your issue to them.
Let me know if you have any additional questions!

SOURCE: pioneer pdp 502mx goes to standby no picture after power on

Contact Pioneer at 1-800-421-1404 about getting an in-home power supply replacement. This is a known issue with some plasma displays. Some of you would experience a loud pop and then the power supply fails. You get a red light below the ON button, when you press on, the red light will turn green for a second and then back to red. The plasma display will not turn on after the power supply fails. Call Pioneer at 1-800-421-1404.

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.

We have had problems switching on our Pioneer PDP-507XD plasma tv. The standby light just flashes. We were advised to change the power supply unit. We hav4e done this and it has not solved the problem ...


I've been running across a lot of plasma tvs where the power supplies are not bad, but the X & Y-sustain boards are faulty. My advice is to change those boards out as they are responcible for lighting the plasma gasses in the tv. You can attempt to replace one at a time (cost reasons), but it is recommended to changed both at once.



Hope this helps, please rate. :)
