Sanyo dp50842 no sound with av cables

SOURCE: ps3 hdmi-av

i currently have the exact same problem...i always play HDMI but i went home from college for thanksgiving and wanted to play on a regular AV jack TV, hooked up, and have no picture whatsoever...and i think it's because of the settings on the PS3 since it's set to send out an HD signal...Well i found this straight from Playstation3.com, on the support/troubleshooting section

"

• If the video output settings on the PLAYSTATION®3 do not match those of the cable or TV in use, there may be no picture. If the screen goes blank, turn off the system.
• Then, with only the PLAYSTATION®3 and the TV connected, touch the system's power button for more than 5 seconds to turn the system back on. The video output settings will automatically be reset to the standard resolution."

TV Connectivity
The issue of connectivity between the PS3 and the display is very complex and depends on the type of TV (Analog, Digital or HD Ready), the maker of TV (until recently, only Toshiba TVs have component AV connections as standard in Europe, most other Euro TV sets use SCART which can not carry an HD signal) and specification of TV (the very latest HD Ready TV sets have wider connectivity options than earlier HD "capable" TVs from the same manufacturer which may have lacked HDMI), and finally the configuration of the PS3 model purchased.

No, when I bought my new plazma tv, and unhooked my old DVR box, I had to go to my cable provider and inform them. they sent a signal and WHAM I was back in Biz.

SOURCE: need some sound to my home theatre system

Hey gr37_98:

1 thing to keep in mind with HT (home theater) systems is that when selecting a particular function that the input to the receiver matches the output to the TV/monitor. Example, you can play dvd's just fine because the HDMI output from the 958 matches the input to your monitor. Many consumers are under the mistaken impression that the home theater receiver can convert the HDMI to some other format, i.e. digital co-ax or optical. This is not the case. To use some other input the receiving device must have the same function & that particular input must be selected in order for the receiver to amplify it.

That being said, when you previously tried the digital co-ax connection did you specially select that input on your HT receiver? If you didn't, the receiver would be expecting to be processing audio from the HDMI input & would ignore the digital co-ax. You may also need to select that output on the monitor in order to active it, which, in most cases, would be odd. I was attempting to access the owners' manuals for these units & decided to respond with basic info hoping to get you up & running. Respond to this post if you have any additional questions.

peace-out

The fact that the screen illuminates properly and does not stay absolutely pitch black means that the backlights are working properly.

A faulty LCD Controller Board (or TCon board for short) could possibly cause the symptoms you describe. The Tcon board is usually located under its own RF shield and will have a large braided steel multiwire cable coming into the bottom of the board and several flat ribbon cables connected to the top by little plastic flip up connectors. A replacement board can be purchased on Ebay for around $70 plus shipping. See the following link for one example:

Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the item information at the website indicated.

Just don't buy any that say AS IS for their description of condition. That is EBay speak for broken.
Make sure they say TESTED FULLY WORKING in the item description.

The best way to be sure you are getting the right part is to open up your set and check the part number that is printed directly on the circuit board itself. Then look that part number up on the internet or type that number into the EBay search box.

Just typing in the model number of your TV will sometimes give you a few different part numbers so you have to confirm which part is in your particular set.

Make sure any part that you order online has exactly the same part number as the one you are replacing. Sometimes it it just the last few digits that are different and it can make a difference.
