I turn on the Tv the sound comes on & the picture is blank Cablevision was here & said it's a problem in the set


He is probably not an expert (just kidding, of course he's not..) First, try connecting the Cablevision Box to another TV (if you don't have another HD TV, use the yellow/white/red Composite connection.) If there is still no picture, the box is no good. If there is, then try a different output from the Box or other inputs on the TV. Are you using HDMI (HD connection) out of your Box? Is the TV 720p or 1080p? Set the Box up (from the menu) according to the specs of your TV. Hope I helped.

This is typical of dried up old capacitors. The problem can be cured by keeping the TV on for days. The moisture in the air will be the cure for the dried up capacitor. It will be good as new if you use more frequently.

Try this (may not work):

1. UNPLUG power from TV at wall outlet.
2. Turn ON the TV (with no power cable plugged in).
3. Plug power cable back in (at wall outlet)
4. Turn ON TV (don't use remote this time).

Hope this works!

No picture or sound


Have you re-connected the cable connection back into the TV from the player? There should be a lead going from the player & into the rear of your TV, I expect you are using a HDMI cable which has a a small flat-like end on the cable, re-connect this & try again.

Code says check connections or power. RGBHV or YPrPb may be inval


Dunno. But if the tv has been 'reset' you will need to re-assign all devices (via NetCommand). Also complete the setup again to verify audio & video selections. If you can select "video" on the remote, you should see various video options...including brightness, etc. If OK...you need to get the right device assigned to the TV for viewing from cable box.

Philips LCD 17PF8946/37 TV not working


The good news is that the "No Input Signal" message means that your TV is not broken. If you are trying to watch cable, then you have simply turned the TV to the wrong input channel. If your cable comes into the Philips using a coaxial cable wire, use the Philips remote to change the channel to Ch.3 or 4 - whichever channel you normally watch cable on. Make sure the cable box is turned on if you have a cable box. If the cable box connects to the TV using another type of wire, use the Ch+/- on the Philips remote and go through all the AV channels until you find the right one. Good luck! Let me know if you need additional help.

No sound from plasma to home theatre


First off it's always best to start from scratch when it comes to home audio. LoL. Many times I've been in this situation.
So with everything disconnected. You should have your HDMI, COMPONENT, RCA(R,W,Y)
HDMI and COMPONENT are the exact same thing and in all preference COMPONENT is far better thand HDMI for the pure fact that each wire is in it's own casing and insualted to avoid feedback from the other wires.
Anyways, with everything disconnected we begin
From you Cable/satellite box- Run your HDMI cable from you cable box to your HDMI 1 input on your tv.(If your speakers were to work on your tv you would automaticaly get sound and picture)
That should be all that you should be running from you cable box. Now that we have one thing running we go to the next thing.
From your TV run your audio out (RCA Red/White) to your amp. Usually your preference but more than likely your TV IN on your amp.
With your amp now set on TV, you should automatically get sound from your tv. and if your running an HD cable box even though your only running RED/WHITE to your amp, you will still be receiving Digital sound.
Most new amps Should have a digital input and if your running and 1080iUp this one RCA plugin will give you dolby digital sound from your dvd player to your amp. Then running a video rca up to your tv, will give you the picture, while the digital out on your dvd player to your amp will give you dolby digital sound.

It's a basic simple step to get sound. Like a continuing current. So just as long as you have your cable to -- tv -- home theatre. Everything should work. Otherwise I would go and check your cables and make sure they are not faulty.
I hope this confusing walkthrough helps.
