Almost always this is some sort of RFI (Radio Frequency Interference) either being generated within the tuner/tuning parts of the television itself, or a nearby component... do you have anything nearby the TV that has a huge transformer coil such as a Reciver/Amplifier?

I would suspect a cheap DVD player before the playstation, but I've had multiple components in which I had to move them away from the TV.

Y Component Cable Related - Internal Static Noise


It sounds like one of those cables has a defective ground. The static noise you are experiencing is cause by the cables not inside the TV. Try using different cables to isolate the problem and get new ones.
Good Luck.

Constant buzzing noise when using dvd player, playstation etc.


If this "buzzing" sounds like a low frequency hum, then it is probably a loose or bad cable from the equipment. I am assuming you have this connected to an AV receiver or the tv. If the cables are not securely connected or is a damaged cable it causes the ground to be suceptible to "noise". That is what I would check first. Let me know if that fixes the problem, or what you did right before you noticed this issue.

Green light is on ...white noise sound but no picture


This TV finds the connected input sources
automatically for AV1, AV2 and Component 1-
2. It is presumed that RGB and HDMI/DVI
sources are connected.

Check your setup to see if the audio is turn off but if you have a clear picture you should have sound.

Time to call a TV Tech if you are not going to repair the unit.

My lcd tv makes a humming noise


Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

Humm coming from speakers - can't get cable to work


The RF input is the correct one for a cable signal. The other sources use the RCA and other ports which you can connect to other devices, like DVD or VCR players.

If the humm noise only happens when you're on the TV channel then it's likely just the station. Try changing the channel and see if that helps, and make sure the coax is screwed in all the way. Also make sure the other end, if connected to a VCR or other stuff, is tightly attached. If you share cable with many other people and the signal has snow (white spots on the TV), then you may need to buy an RF signal amplifier to reduce the noise.

Source changes the input (RCA versus coaxial versus component inputs), change the channel for different channels..

Progressive scan


Approach 1: Try unplugging the DVD player from the wall for an hour, then plug it back in. It may or may not reset to the factory default settings, which might put it back to "interlaced" output.

Approach 2: When a DVD player is switched to progressive scan, it uses outputs different from the coax cable "TV out" and the COMPOSITE outputs (often yellow, white and red RCA jacks. If you have the proper cables, you can connect them to both the DVD player and the TV, then cycle through the AKAI TV's "source" settings to switch the TV to the new cable input location.

For example, if the DVD player has "component" outputs (marked Y, Pb, and Pr) hook up RCA plug cables between those jacks and the AKAI TV's Y, Pb, and Pr jacks. Connect the Y to Y, the Pb to Pb, and the Pr to Pr, of course. The LCT3285TA has two sets of these jacks. Either will do, but note if you use YPbPr1 or YPbPr2. Once this is done, push the source button on the side of the TV (or on the TV's original remote) until it shows YPbPr1 or (...2 if that's what you connected). If the DVD player is on, you should now see the DVD menu or the picture from the DVD. Now you can use the DVD remote to switch back from progressive to interlaced video. The picture may go blank at this step.

Now push the TV's source button again until you see "3" or whatever channel you had been using in the upper left of the TV screen. You should see the DVD output picture (menu) again. Back to normal.

If your DVD player doesn't have YPbPr connections, it may have a HDMI or DVI jack.
The AKAI TV also has a HDMI input, you *could* get and HDMI cable (or DVI to HDMI cable if the DVD player doesn't have HDMI), hook it up, then cycle through the TV's source inputs until you see the HDMI in the upper left... in the manner I've just described.

Final Note: The progressive scan output of your DVD will actually give you a much better picture on your AKAI TV than its interlaced output. To take advantage of that, you'll have to hook up YPbPr or HDMI cables between player and TV and switch sources when you want to watch DVDs instead of TV programs. You may need additional cables to send the stereo audio output from the player to the TV for the progressive source hookup.
