Lpe200 ericsson radio has no sound

Hi,
Might just be the internal speaker. If it's got provision for an earphone or a headset, give it a try. If likewise no sound on the earpiece or headset, then a couple of possible problems:
1. audio amp;
2. volume control;
3. squelch circuitry; or
4. RX circuitry
All involves opening the set and diagnosis. An on site or in service repair is required.
Hope this give you an idea or two. Good luck and kind regards.
