The left speaker on our LCD tv went out 2 days ago - the tv is mounted on the wall - once in a while is comes back

Might be the power supply, try out a company named ShopJimmy.com. They have been great to me in the past and are always helpful. I included a link from your model page on their site. Hope that helps!

If this is a "new to you" TV, keep reading. If it is a brand new TV, I'd be on the phone to the store to have a replacement ready for delivery / pick up. You do not want to be repairing a TV that is 2 days old.

The first thing to do is determine if the distortion is coming from the speaker or if it is on the signal going into the speaker. Do both speakers sound distorted or only one?

You didn't include the model number of your TV, so I can't speak to specifics. Look for a terminal on the rear of the set identified as "speaker" or "external speaker". If provided, there will be one set of terminals marked for the left and one for the right external speaker.

Connect a speaker directly to the terminals marked for either the left or right speaker (connect to the one that sounds distorted if only one of the built in speakers works correctly - other wise pick either speaker terminal pair.). Speakers that have RCA plugs on them, have built in amplifiers, require batteries or or to be plugged in to an outlet should not be connected here.

Alternatively, you could connect a pair of stereo headphones or earplugs if your TV offers a jack for them. It would have a headphone icon or say "phones" above the jack if one is provided.

Once connected, turn the TV on, lower the volume and set the TV to enable the external speakers / disable the internal speakers. This may be done via menu item selection or a small switch near the speaker terminals. Slowly increase the volume to listen to the quality or clarity of the sound coming from the speakers you connected. If they sound distorted, the problem lies with the audio amplifier in the TV. If they sound OK, then there is a problem with the speakers in the TV.

If you can't return the TV, you may have to see about using the left and right audio line out or HDMI jacks to send the audio to an external amplifier and speakers to hear the program.

I hope this was helpful and good luck! Please rate my reply. Thank you.

Hello,

Mounting an LCD (Liquid Crystal Display) TV on the wall may seem a bit overwhelming at first; but it's not that difficult. With a few simple tools, a proper mounting kit and a helper, the job will be a breeze. With a little bit of patience and an hour or two, your LCD TV will look great. Follow these steps to learn how to mount an LCD TV on the wall.

Things You'll Need:
LCD TV
Mounting kit
Tools
Step 1
Find the best spot on the wall to mount the LCD screen. Think about how much room you may want on that wall, especially if you plan on mounting speakers, too. You could hang a poster or picture relative to the size of the television on the wall to see if you like the placement.

Step 2
Pick a mounting kit. You can purchase mounting kits online (see Resources below) along with many other sites. Look to make sure the kit and TV are VESA compatible so that you have standard measurements and quick, easy attachment during the mounting process.

Step 3
You may already have tools needed to mount the TV. You'll need a set of screwdrivers, a socket set, a saw capable of cutting into drywall, a drill and a measuring tape. Having a stud finder with a built-in level is also great to pinpoint the exact location of the stud. The stud finder will be useful if you'll be running wires through the wall.

Step 4
Get the location for the TV picked out. Check near the bottom of the wall to see if the area you plan on using to run the wires is free of obstructions. Using the stud finder for this will make it easy.

Step 5
Find the studs. You should use at least one stud when mounting the LCD screen to make sure that the mounting bolts are driven into something solid that will support the weight of the TV and the mounting bracket. Using two studs is ideal for mounting larger TV's, those with screens larger than 37 inches. Use a pencil to mark the drill holes for the anchors and stud location.

Step 6
Secure the mounting rails to the back of the LCD screen. Double check them for proper fit. Make sure that they're hidden behind the body of the television for a finished look.

Step 7
Cut the hole for the wires to come through by using a drywall saw. The easiest way is to pull them out at the electrical box. This avoids having to go into the basement, closet or otherwise. You can purchase a wall box at your local home improvement store to place in the exit hole of the wires.

Step 8
Drill the holes for the bolt anchors in the locations that you measured and marked previously. Place the bolt anchors into the holes and tap them in with a hammer.

Step 9
Secure the wall mount to the wall. You'll need a socket wrench to ensure that the mounting bolts get snugged down tightly to the anchors. Use a level to make sure you've done an even job.

Step 10
Grab a friend or family member to help you lift the LCD screen onto the mount. Make sure it's locked down tightly and the screen is set to go.

Hope this helps and Good luck

There should be at least 4 mounting holes (VESA mount), and they should be used.

To Display your LCD TV using a Wall Bracket:

If you decide to wall mount your LCD TV, always use a ULlisted wall bracket appropriate for the size and weight of the LCD TV: 32HL37/32HL37U/32HL17/32HL17U: 38.6 lbs (17.5 kg)

37HL17: 46.3 lbs (21.0 kg)

42HL17: 59.5 lbs (27.0 kg)
1) CAUTION: Two people are required for installation.

2) Unplug and remove any cables and/or other component connectors from the rear of the TV.

3) Follow the instructions provided with your wall bracket. Before proceeding, make sure the appropriate bracket(s) are attached to the wall and the back of the TV as described in the instructions provided with the wall bracket.

4) After attaching the appropriate bracket(s) to the wall and the back of the TV, remove the pedestal stand from the TV as described below.


Removing the Pedestal Stand

1) Carefully lay the front of the unit face down on a flat, cushioned surface such as a quilt or blanket. Leave the stand protruding over the edge of the surface. Note: Extreme care should always be used when removing the pedestal stand to avoid damage to the LCD panel.

2) Remove the jack pack cover on the back of the TV to expose the pedestal stand screws. The jack pack cover can be removed without tools.

3) Remove the five screws. This will allow removal of the pedestal stand.

4) Once you have removed all five screws holding the pedestal stand in place, remove the pedestal stand from the TV by sliding the pedestal stand away from the TV.

It is not you tv its the plug on theb wall. It is probably loose, and causing the intermittent problem you are having. You may notice looseness as you plug it into the wall. Your TV is fine.

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.

If this is a new set, return it for an exchange. This one sounds like an LCD set which uses a "back light". This back light is not working. This is a warranty repair or exchange.

check the relay

If you have external speakers near the TV they may cause this problem. Moving the speakers away from the TV and demagnitizing the set will fix the problem.
