Lg lth854 not reading dvd's or cd's

Hi,
I have an lg lht854 dvd surround sound system hooked up to an LG 42" lcd tv. Everything has been working fine, until tonight when I was watching a rented movie, it froze up. I removed the dvd, cleaned it and put it back in. It wouldn't read the disc. I tried powering down the unit, unplugging it, other dvds and cds and its still not reading any disc. It will try to and say no disc. I've only had it for 2 1/2 months and never had any problems. Please let me know if you have any ideas on how to fix the problem. Thanks,
Chris

    I have the exact same problem. Did you solve your problem?

    Exact same problem, It happened as soon as the 90 day warrenty went up.

    Same situation in a 7 week ownership. Insert a disc one day and I get a display of "No Disc" or something similar on the display. Cleaning disks are not recognized, no CD or DVD is either.

    Same problem.....

    The same thing happened to me almost exactly 90 days after purchasing my DVD player; seems suspect to me that other people have had the same problem around the same time. When I try to fix the problem with a cleaning disc it will not read that either. I Should not even have to worry about this thing so soon in it's life.

    I AM SURE WE DID NOT ALL PURCHASE THIS SYSTEM ON THE SAME DAY. WHY IS LG NOT FIXING THIS PROBLEM FOR US? IT IS A MANUFACTURERS DEFECT AND SHOULD BE FIXED.

    The disc player on my machine simply stops reading discs. I had Best Buy and the Geek Squad switch one machine for another, and the same thing happened again. Very frustrating.

SOURCE: my dvd combo does not read dvd

There are separate lasers for CD reading, and for DVD reading. This is why it is possible to have a drive that reads only CDs but not DVDs, or the other way around. And your particular combo unit seems to have a lot of these problems. Since the drive doesn't work it's almost definitely a problem with the drive itself (I'm assuming that there is nothing wrong with the discs you tried to read). If that drive is still covered by a warranty period, send it back for repairs. Otherwise, I can't see the harm in trying to tinker with it yourself as the DVD portion of it is dead anyways. Ummm, on a side note...CompUSA is going out of business and they are selling things cheap. I got a DVD lightscribe burner for $40...booyah!

SOURCE: Various LG DVD Player

Some models of PIONEER cd players had radio frequency problems that caused them to work on and off. Are you near any radio or braodcast towers? Poorly shielded power supplies cause this as well. A weak laser diode in the pick-up assembly in model runs could be the problem. You might want to Google the model number and see if this is common for these units.

SOURCE: high-pitched sound when using surround sound

THANK YOU Guest (4/10/08)!!!
That was exactly what I needed! We have had our system for 4.5 years and suddenly, the FM feedback on everything, but DVD and Radio! Your fix helped. Once I set all my presets (at least the current one) to a clear station, the feedback stopped. Hallelujah!! We can enjoy this piece of junk once again! ;)

SOURCE: LG 5010 42" + Xbox360 + DVD RECIEVER/ Surround Sound SET UP HELP!

soulshaun:

I need some clarification before we can proceed. Which audio/video cable did you use to connect the 360 & your home theater receiver & TV/monitor? It makes a difference which you use. The HDMI cable would be the preferred one to use. The fact that the receiver only has 1 HDMI connection limits your options for other digital connections. Respond to this post & I can provide additional info. I have found that when responding to someone's question, I have a tendency to provide too much info on the 1st response.

peace-out

CD will not play in surround. How do I set to have music play in surround?


Unless your CD's are DTS-encoded, you can only SIMULATE surround or employ Digital Sound Processing from stereo sources to create virtual sound spaces and effects. The manual describes it on page 13.

Like any spice, using sound modes is a matter of personal taste.

I need severe help. LG cant even help me. I have an LHT854 home theater system. The only time I can use surround sound, is if I watch a dvd player on it. My Tv's only "Out" is an Optical out....


Is the digital TV-related sound actually originating in the unidentified TV or would it be better to get it at, say, the Cable Box, which IS a hi-fi component, whereas TV's are amost always NOT so?

I'm pretty sure the TV manual may explain the use of its optical output.

How can i hook up surround sound to cable box and ps3


Hi,

The easiest way will be to connect your PS3 and cable box to the TV by HDMI and then run an optical cable from your TV to the surround sound system.

I have an almost exact set-up and you will only get sound out of your rear speakers when the TV channel is broadcasting in 5.1 Ch Stereo. Otherwise the sound is limited to your front, center, and woofer speakers.

Is the Unit suppose to come with Audio Jacks or the progressive scan output jacks? Mine just came with one video Jack?


You need to go out and purchace a audio optical cable for your unit, it does not come with it because the device will give you sound with a DVD just not with your TV. the optical cable hooks up to the back of your TV and then to the back of your LG LHT854 player. You might have to adjust some of the options in your sound menu but once you have the cable you will be on your way to surround sound with all of your devices.
