Question about LG LHT854 Theater System

Open Question

Lg lht874 Surround sound system. Just moved and reconnected everything. The wireless reciever and transmitter just blink their blue lights at each other and the blue light will not become steady- so the audio coming out of the rear speakers only comes on intermittently. Called tech support, where they had me turn it off and on a million times, only to finally say that I was going to have to send it in....ICK. I jsut want to get it to work again, when it works, it sounds great!

SOURCE: center speaker and wireless rear speakers have no sound

I had the same issue, but apparently...it's not an issue. What I discovered is that the system was fine, but the station I was watching didn't broadcast in 5.1 surround sound. Therefore, only the front speakers will have sound. Try putting a dvd in, or listening to a gameing system through it. If you don't have sound after listening to something that puts out full surround sound, then you know you have an issue.

SOURCE: LG wireless dvd reciever system

Hi, I had the same problem, it seems to be a design error of LG or a typical problem with some component in the wireless transmitter. It is basically caused by the transmitter heating up, leading to a clock drift with the result of the receiver losing the signal. I tried to cool the transmitter in the fridge before using so it will run for about half an hour before producing this error (depends on the room temperature as well). My solution is to remove the plastic case of the transmitter unit and place it in a cool place where it does not catch heat from other devices. Without the case it does not overheat and also takes less space, just be careful if you have children. I placed the naked Tx unit behind the TV so it does not matter. Hope this works for you as well.

Acoustic Research Model AW871 wireless sterio speakers


Your connection between the AR transmitter and the ONKYO receiver sounds solid. I'd guess it's the wireless speakers that are the wrong point, or at least that's what I'd look at first. Doing a bit of research, I noticed a couple minor points. First, these seem prone to RF interference from other RF devices. Have to tried switching channels on them? Second, someone reported theirs would not work properly unless the speakers were turned on just before the transmitter, and turned off shortly after the transmitter. Apparently you have to hold the button on the front in for 5 seconds to turn the speakers on or off. I know that's rather basic, but it's been a few days and no one else has responded, so I figured we should start somewhere.

No sound on lg lht874


Disconnect all speakers and check all sound channels with one speaker. If no sound again it can be only main board. Contact directly by mail to our technician support, click "about us" avsystemparts, probably we can help resolve the player troubleshooting.

My LG LHT874 sound system stopped working. It has power and displays everything but when I turn the unit on it only stays on for about 5-10 seconds then it turns off. I took the shell off and determined...


Try labeling and disconnecting everything. See if the power stays on then. If it does, you're probably hitting some kind of protect. If not, you probably have a bad power supply. Try heating the circuit board where the power cable goes to with a blow dryer to see if any parts are bad. Sometimes the system will stay on if certain weak parts heat up.

No sound from rear speakers on the lifestyle 18


The SL2 works in such a way that the speaker satellite out put from the bass modules is fed to the input of the SL2 transmitter (remember, transmitter) then the sattellitespeakers are connected at the other end of the room to the receiver. An initial blinking green light should be seen and once the system is turned on this turns into steady green. Both the SL2 transmitter and receiver operates via WIFI.

Glad to be of service...
