LG LH-CX640W Home Theatre - Broken (1 Viewer)

[hugomax]

HiWe have a LG LH-CX640W Home Theatre with 6 surround sound speakers. The DVD/VCR unit has become faulty and no longer plays DVD's.

We want to get a replacement DVD/Home theatre system which works with the speakers. We have been told that this is not possible and the whole unit, speakers included, needs to be replaced.

Is this true? It seems a real waste. What options do we have? It would be too expensive to get the home theatre system fixed.

Any advice would be gratefully received.

Many thanks

Many all-in-one home theater systems like the LG use proprietary speaker connections and very low impedance speakers that are not compatible with anything else. Using low impedance speakers with receivers not designed to work with them can cause severe damage to the receiver. This is one of the compromises these systems make in order to simplify and consolidate the components into a single unit.

Looking at the manual for your unit, however, it seems as though the speakers connect using regular speaker wire in spring-loaded connectors. Also, according to the specs, the speakers have an impedance of 6 ohms - that's not as low an impedance as many all-in-one speakers, and could conceivably work with many standalone receivers.

The subwoofer, however, is a passive model with an impedance of 4 ohms. This is less likely to work with a new system.

Normally, I would agree that you should not try using the speakers with another system, but in this case, it's possible to use these, but it will depend greatly on what equipment you opt to get.

What is your budget for getting this system back up and running?
How important is having the DVD and VCR back in the mix?
Do you have any other sources hooked up to the system now (cable/satellite, high-def)?
Any chance of wanting to expand the system in the future (Blu-Ray)?

I see a couple of options available to you, depending on your budget.
- Try and find an all-in-one that will work with your speakers. This is probably the least likely to happen. Most all-in-ones will come with their own speakers, anyway. Also, while the LG used close to "normal" speakers, that's a rarity.
- Get an inexpensive 5.1 receiver that will drive the speakers, and add a DVD player (or DVD/VHS combo if you can find one) and probably a subwoofer, too.

If you can answer the questions above, hopefully we can provide more specific options for you.

you can still use it if you want to keep it all you have to do is buy new dvd player and connect the wiring from the new dvd to the home theater thats exactly what iv done and its working perfectly iknow it looks a bit ugly but who care it works hope this will help you
