Sounds like an issue with the remote. Try other functions, too. You may need new batteries.

Sounds like a bad connection or setting on one of the devices. First check that the leads are plugged all the way in, if your using the RED/YELLOW/WHITE leads you need to make sure they are pushed all the way in because they can feel ok but not be all the way in. Same with all leads but those in particular can be troublesome unless they are fitted correctly.

Of Course there is a fuse at its main power regulator board. but, you must have sound knowledge in electronics, to replace it, especially to Plasma displays. If you wish to get more details, check the site linked here. If you have confidence, follow. http://electronicshelponline.blogspot.com/

Not a button, its an option in the menu. Check your manual.

likely a coil or small transformer in the set is vibrating hard enough to make it squeel, it would have to be located with back off by listening to see where it comes from.

cure would be to replace the entire board it is on or hot glue the part that is causing this to dampen the sound.

If it is coming from the front screen unit that is a more serious issue.

if you have the right tools then you can do it, make sure unplug the tv unit first while replacing the board. then mark or put a label to the connector that you were disconnect not to interchange that can cause of damage to the other board.

It costs more to replace the screen than it does to buy a new one. It will require a complete dissassembly of the tv to replace the screen. Not worth it.

There are a lot of sets that do this and it has been attributed to bad capacitors.
One thing is for sure and that is that the power supply in your set is pulling too much current. You can see the information on bad capacitors here:
Then you can decide what action you want to take. IF you decide to have it serviced, call around and get bids and you take the set in and you dont get charged a service call.

press the "CC" or "c" button on your remote.facing the remote towards the tv and keeping the tv on. keep this button pressed for 5 seconds and closed caption option will be turned off.if keepuing the button pressed does not helps.then press the "CC" or "c" button randomly for 4-5 times then check. also if this does not helps then try this :-- turn the unit off and hit the Menu Button. you could then setup the CC directly in the DVR and it pumps the CC info over the HDMI cable along with the Video Signal in High Def. Just switch HD-DVR box MENU 4:3 Override setting to "OFF" and now CC will work on the SD channels. ---------- Eliminate the closed captioning setting if a black box appears on the screen. The box is used by viewers who are hard of hearing. You can get rid of it by pushing the "Menu" button on the remote, then selecting "Setup" on the screen, then scrolling down and pushing the "CC" option. You'll see a list of controls, the top of which reads "Mode." Highlight it and cycle through the options until you come to "Off." Select it and exit the menu with the "Exit" button. The black box should disappear. Adjust the SAP setting if the sound isn't coming in, or is coming in oddly. The SAP button should be in the top right-hand corner of the remote. Pressing it lets you move through the various options. Set it to "Stereo" or "Mono" to see if it corrects the problem. You might also check the "Mute" button to see if it is activated, or simply adjust the volume. This will help. Thanks please keep updated. please do rate the solution positively .thank you for using fixya.

This would well be worth fixing. At most your looking at $250 to replace some IC's on the circuit board. Possibly convergance board.
