Receiver is powered, monitor is not

It could be a relay that burnt out, they usually dont show any signs of damage, or the motherboard could be fried too with no signs of damage eather! Hope this helps!

replace the power supply on the plasma TV

Hi I also having the same model but the receiver is not working properly. So I don't no what to do.

Pioneer plasma pdp R03U shuts off and tv shows E01 or action freezes while soun dgoes on and then stops E01

Hi djn Collinswhen your DVR is not allowing you to pause or rewind live TV you will need tounplug the receiver for 10 seconds and allow the receiver to power back up and acquirethe signal. Then you will want to try the functions again and make sure theyare working fully.

power supply call pioneer

I believe that this monitor will not work unless you have the cable from the media center to the monitor hooked up, I have all the parts from one of these due to the screen being defective on one of my customer's TV like yours. I have the connection cable that I could sell for $ 20. + Priority shipping of $5.65

You should return that box to the seller. There are half of dozens senarios which you should not have to go through.
When you are not able to turn of the power of the media box,that is a sure sign of trouble(assuming you have already replace it with the good battery.)
Instead of going into details,you should get your money back,and i DO NOT recommend you to buy a media box from ebay.To me,who would want to sell the media box that works with the plasma TV monitor?That is a video/audio connection board for the tv,without it,the tv is useless.

ok sounds simple you ran the lines threw the tv instead all lines should be ran threw the sterio

see once you turn tv off this cuts the outputs out so now no sound will happen
your sterio should be equipted to take inputs of tv
you want everything to be inputed threw receiver thats why they call it a receiver the outputs on tv goto inputs on receiver
you need to redo your wireing so that this which i described is correct again

The problem is in your cable connection on the back of your monitor or Box. I had the same problem and solved it by reattaching the VGA cable that was loose.
