Question about Panasonic TH-42PX500U 42 in. Plasma Television

Picture, No Sound from HDTV Box

I just hooked up a Scientific Atlanta Explorer 8300 HD cable box, and the only way I get sound is on the coaxial feed (but a poor picture quality) with the tuner on channel 3 of the TV. HDMI and component cables both have picture, but no sound coming through. Note: Both HDMI and component cables send both picture and sound when unplugged from the cable box, and plugged into the DVD player.

    42" LG LCD using cable box 8300( Set up) Cable from out side into box,(8300) Hdmi from box to tv.



    Problem: No sound at times, intermitting when changing stations.



    No sound when changing stations at times.Would have to turn off tv to restore sound or change channel over and over and return to channel we wanted to watch to get sound back. Also some HD stations that suppose to be in HD ( Channels in the 1000s like 1008) ( chan 8) doesn't come in HD has is should. I've replaced the cable box many times with no corrections.

    I'll try to reroute directly to my dvd player as stated in one posting on here. Get back and let you all know how I made out.

I can't turn on closed captioning on Hitachi with Comcast scientific atlanta explorer 2200 cable box. Any words of wisdom?


Both the set and the box used should have the closed caption feature.

If box is in line to rear audio/video jacks you will have to engage the CC from the box.

I doubt it will work if hooked that way from within the box---go to menu and in CC area in either set or box select CC1 which is the most common one used.

Did you call Scientific Atlanta to find out if this could be a software issue in their box, or if there is a failure occurring?
I have had cable boxes do similar things to what you are describing. It turned out to be the box was defective and had to be changed. They were not serviceable. I believe these cable boxes were made by Scientific Atlanta.

You should not lose any picture quality from the DVD player. I am currently having the similar setup with PS3 as the Blu-ray DVD player with HDMI and a Samsung DVD as regular player with component cable to a Samsung LCD TV. Remember the quality on Blu-ray is better than normal DVD so don't expect more than what it is.

Scientific Atlanta Explorer 8300 says ''EXPLORER not AUTHORIZED


The message is so cryptic...it's right. There is no way to unblock it yourself. This is the box connecting to your cable company's servers and being told that, "no, you are not allowed to access content, disable yourself." It is referred to as "bricking" as the box is now as useful as a brick.

If the box worked previously and all-of-a-sudden this happened, then it could be that there is a typo in your account, and your cable company can correct it quickly. It could also be that your bill is past due and needs to be paid. Generally if it's a past due issue, a payment will reactivate it instantly.

If you are not paying for digital service and you bought this from eBay or got it at a flea market, then you'd need to add service and add the box to your account. The problem is your cable company might not like one box reappearing on another account--it seems stolen. They may just want the box back, and give you another that would work.

Picture too big for tv


Its the signal from the cable company. There is nothing that you can do because starting next month everything is going to be like that.

How to connect new HD cable box to receiver


HI:
You are using a new HD Cable box, that are using componet video cables for HD, Unfortunetly this receiver does not have componet inputs, so you will just have to run the audio from the televison directly to the receiver by connecting the video out and audio out from the television to the receiver's video Input one. This will require a normal RCA composite cables yellow,red,white. Connect one end of each of the cables to televisions output terminals, and the other to the input one on the receiver. Note: Your TV might have a seperate term called Monitor out, Connect the yellow here, and the red and white to audio out. You can do the same for the DVD but you have to use the same cables,Also the television will not display HD picture this way as this is not a HDTV Receiver. If you just want TV sound to the receiver then do not use the video(Yellow) cable just use the audio out terminals from the tv and connect to Input one on the receiver. you can do this with the cable box also but you have to use RCA type cables . If you want the full HD experience then a new up todate receiver is necessary.

Off Air?


The Scientific Atlanta box was a cable box and recieved CATV signals. The Direct TV box is satellite only. You might check if it has a built in ATSC tuner for off air digital signals. Direct TV in most locations offers the major networks in HD format.

Changing Screen Size on Samsung HP-R4272


you must not have the correct picture settings in the cable box, as although they are not HD they will still be widescreen, so check both tv and box for picture settings.
