Turning off and on loud noise

Tv will constantly turn off along with grainy background that says "no signal" and loud noise that occurs when the tv turns off. Then the tv turns back on and does it over again. Not sure if it is the cable or the tv itself. It does this for every channel. I tried plugging and unplugging the tv and retwisting the cable cord. I do not have a cable box

SOURCE: HDMI connectivity

I have the SA8300HDC STB from Time Warner. I get this error from my DVD recorder, not from my HDMI connection. I've read that the error is due to copy protection. The only solution I've read about has to do with a new Samsung Set-top box from TWC. Funny this copy protection error didn't ever come up with my old VCR connection to the HDTV. TWC apparently told a lot of people that the problem would be solved by a software update from TWC in October 2007 & then in December 2007. Guess TWC isn't sure what the problem is but everyone who has mentioned this Samsung cable box has reported success with their HDMI connection.

SOURCE: Vizio makes loud static noise, picture goes fuzzy.

You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.

SOURCE: 52LG70 sometimes turns off and on periodically

I had the same problem. I changed the 4-3 setting on the motorola cable box. Turn off your cable box and press menu. My 4-3 setting was set to auto. If you turn it off, you lose the 4-3 aspect on most channels. I changed mine to 480p and so far it seems to be working. Worth a shot.

SOURCE: tv turns itself off when it warms up...unplug it a

There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe

Background noise and music is so loud we can't understand the dialog


If the sound was disconnected, you would hear absolutely nothing at all. There is a problem with the sound signal itself, so connecting external speakers probably would not help at all. Electronic components have failed, which caused the sound problem issue.

Whynter Portable Air Conditioner Model: ARC-14S. Problem: It sounded as if something fell inside the unit while it was operating (cooling) then it started to vibrate horribly. The vibration is only...


Hi,Whynter Portable Air Conditioner has many moving parts, and they all make noise and cause vibrations. Some of these parts are more likely to causing shaking and loud noises, and sometimes this signals a larger problem, something to watch and scrutinize. If serious enough, it calls for a repair.

Loose Parts

Loose parts cause the majority of shaking and vibration noises in your air conditioner. A few of the most common loose parts include the air compressor, the piston rods and even the fan or blower unit itself. These noises are clunking, clanking sounds that occur along with a vibrating action. The only method of repair is a complete compressor replacement, which is a repair only a certified air conditioner technician is qualified to make. The compressor is a fully sealed component, so individual parts in the compressor cannot be repaired.

Fan Blades

Fan blades cause noise, shaking and vibrations even when properly secured. If fan blades contact the exterior structure of the air conditioner due to a bent fan blade or broken and misaligned grate, a constant, repetitive noise and vibration results, which sounds like a ticking or banging from the interior of the air conditioner. Vibration in this case is limited but still present.

Mounting Brackets

When an air conditioner shakes, there is a problem with the mounting brackets. These brackets hold the air conditioner compressor steady as it operates. Normal vibrations and shaking would otherwise occur without these brackets. A loose mounting bracket causes the air conditioner to rock back and forth and creates a clanking sound. As the compressor starts up, this rocking and clanking sound begins, resulting in a very loud and fast vibration and noise. It also occurs when the unit shuts down.

Other Sounds and Vibrations

Sometimes air conditioners squeal, hiss, hum or screech. Each noise is often accompanied by a vibration. Humming sounds along with a vibration may indicate a bad capacitor, the electrical part responsible for starting the machine. Hissing sounds tend to indicate a pressure problem while screeching and squealing sounds are fairly common in window air conditioners and in central air conditioners. This sound is also a result of the compressor motor. It usually starts when the unit turns on and continues through its normal operating cycle. Vibrations always occur in the air conditioner due to moving parts and the compressor motor's operation.


Hope it helped..

Loud static noise without warning


The audio may be randomly disconnecting or something. I know that when my TV has no signal coming in, that it makes a bunch of loud static.

RCA HD50LPW164 turned on TV made a pop


the loud pop you heard was probably a capacitor blowing its top. The grinding noise is likely high voltage arching that was occuring due to rising voltage since capacitor isn't there to smooth it out.

Grainy bdmv platyback


You have a couple of options.
1. Turn down the sharpness on your TV. Too much is overkill, anyway.
2. Whilst watching any movie, hit the triangle button for the movie settings & options. Turn up the noise reduction to +3, also the "mosquito" noise to +3.
These should give you a less grainy picture. Enjoy!

I need a bit more detail on the word "GRAINY". At the outset, your description indicates a poor signal source, but then the word grainy leaves the door too wide open. Clarify please.

KV-XJ29M50 29" TV-Loud thumping sound on startup


Symptoms are not related,what you hear is the high voltage turning on and that is normal if it only does it for less than a second,the grainy picture might be intermitant,dont turn it off,when the picture is grainy tap the side of the set to see if it racts and if it does you know you have a loose conection.This could be outside because of a loose ground on tha cable or inside in the tuner.
