Question about Pioneer PureVision Pro-1120HD 50 in. HDTV Plasma Television

2 Answers

Short in speakercable

After two months of trouble free use, I turn on my Elite 1120HD plasma set, and find there is no audio. Took media receiver to store, was working fine there. So took it back home and hooked it back up. Now when I turn on the set, it flashes for two seconds, then turns itself off, while displaying an "internel protection" message, and the question: is there a short in the speaker cable? Any thoughts??

When the unit displays "overload" or "power off", something is shorting the output side of the receiver. Check the speaker wires on the back of the receiver and each speaker. You should remove each wire and neatly twist the end. Re-insert the wire, carefully watching to ensure it clamps on the bare wire and that the wire does not extend too far from the terminal. If the problem continues: a). Remove the speakers, one at a time b). Turn on the receiver. c). Increase the volume. d). If the receiver still overloads, turn off the receiver and reattach the speaker. Remove the next speaker and continue this process until you have found that when a speaker is disconnected, the receiver no longer overloads. This speaker would then need service attention. If you have removed all speakers, one at a time, and the unit still overloads or powers off, the receiver will need service. Please visit www.pioneerelectronics.com, for a service center near you.

My question is why my receiver it turns off by itself in between two or five hours why is this???


If there is a short circuited component/s at its audio output section circuit, or, the set has been overloaded by output components [speakers], this could happen. Disconnect all the speakers from the set, and check. If it behaves the same, make sure that its audio output stage circuit has the fault. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts.

I turn on my 50PF9956 get sound but no picture. For 2 weeks before it started taking longer to get the picture. I tried the menu with nothing


The plasma picture tube technology lasts only 24 months before it burns itself out, requiring a new
plasma picture tube. The LCD and LED technologies do not suffer from this short life span.
If your Philips 50PF9956 is over 2 years old, you've got all the use your plasma can give.
Fix: new plasma display - the electronics controlling the plasma display are most likely fine - just
like the electronics providing audio to the speakers. Your set's only problem is a burnt-out display.

HDMI XBOX360 Elite -"No Signal"


The connection order can be a key issue as to whether or not the HDMI signals will pass through the system. For best results the receiver should be turned on first, then the source device(s) and then the display. The reason for this has to do with getting the equipment to handshake properly for the HDCP protocol.

If HDMI video will not pass through your receiver, you may with to just connect the xbox using the component cables. Since component will pass through 720p and your TV is 1080i you should expect the same qualtiy and a more crisp picture.

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.

NO VIDEO


I have a Samsung 50" plasma, that has been blacking out over the last 6 months. A 9/2005 set. Now its practically unwatchable as it happens 3 times in an hour. Its not heat related - I have a high volume 9" fan activated on TV power on. Turning the set offf/on usually makes it come back for a now short while. Considering to go put it in the back of my pickup and park it in front of Best Buy and discourage Samsung purchases. This is the 2nd Samsung TV I've purchased (the other a 32" tube) I gave to my folks a couple years ago and its gone bad as well. Samsung product may look good, but their video engineers are not.
