SOURCE: philips 50" plasma ysus board troubles

Check for shorts, blown fuses on ysus, if blown replace entire board, easier than locating many of the parts installed on the board.

SOURCE: how to conect a pc to a panasonic plasma th50px75u?

Panasonic didn't make it a simple matter to connect a computer to this TV since they didn't include a VGA input connector. You can still do it, but it will require some adapters or changes to your PC.

If you're using a laptop, you have two options. If the laptop offers an s-video output, you can use a suitable cable from there to one of the set's s-video inputs. If there's no s-video output, the other option is to purchase a VGA-to-component breakout cable, available at a number of online vendors (search with Google). This cable has the VGA connector to the computer on one end, and 3 RCA plugs at the other end. You would use this cable into one of the set's component video inputs.

With a desktop PC, you can still use one of those two options. In addition, there may be a DVI video output connector available as well. This is not common on computers with integrated video, but is frequently found on many newer expansion video cards. If your computer has this connector (or you install a new video card with one), you can use a DVI-to-HDMI adapter and connect an HDMI cable to one of the set's HDMI inputs. Many video cards with DVI outputs include one of these adapters already.

So while it's not going to be simple, it's certainly possible to connect your PC to this TV.

Is it possible to change fuse on panasonic hi def plasma th50px75u tv. if so what are the fuses and where located?

They should be fuse(s) in the power board and or the Y Board.
When the fuse goes bad it means other component(s) are bad which made the fuse to go bad.
You can try but, just be very carefull use only the same fuse.

My advise is to call a repairman.

This information is for someone that knows electronic.
1000s of volts inside the TV that can kill. Even if you unplug the TV the high voltage can be stored inside the TV for days.

Best of luck.

How i do tv chanel tunig

Hello Ansarielectr, The Panasonic TH-42PWD7 is a professional grade progressive wide screen plasma display. It's not your normal HDTV. You probably already know this. This display requires a component /composite video terminal Board that mounts to slots 1 & 2, or slots 2 & 3. The item number for this component is TY-42TM6Y and can be purchased through the Panasonic support website here for about $270. Once you have this component, you can connect the TH-42PWD7 to a digital HDTV cable box to receive signals. Just make sure you're on the right input signal. Hope this helps.

When i connect my panasonic sc-ht650 to my panasonic tv the picture is in b&w? i'm running the video wire(yellow) from the component video out(above the red and blue) to the component video...

Sounds like your tv doesn't have componant video in, just composite video. Try the yellow video out on the dvd player to the same video in on the tv. The red and white on the tv is for audio left and right.

Game console and plasma displays

You did not list which console you have and what type of cables it has.

Looks like your plasma has:
1 component
1 composite
1 VGA
1 S-Video

If this is an xbox360 or PS3 then you will want to use the component connection, but this one is already used by the cable tuner. Don't worry there is a solution. The xbox360 and ps3 output a higher resolution that your plasma can handle, so use the component with those systems.

If it is an older console, predating the xbox360, then use the composite or S-video connections.

Since you are short on video inputs, you might need a video switch. A switch with both component and S-video connections for future add-ons.

You can find them all over the web, or your local video store like walmart and best buy. Here is a switch i found on ebay that should work:

here is the ebay search i used:

Make sure you buy extra cables, most of these boxes do not come with cables, so buy what you need.

I prefer video switches that don't require a power outlet, but it's your choice. Some of the powered switches, have remotes for the lazy people, but I don't need anymore remotes on my table, keep that in mind.
