Short answer: HDMI between a Sony HT-DDW7500 and an LG 42PJ350R should work — the HT‑DDW7500 provides HDMI switching (multiple HDMI inputs and one HDMI monitor/output) and the LG plasma has standard HDMI inputs for an external receiver. There is no protocol-level incompatibility, so a “no signal” usually means a wiring, cable, input-selection, or handshake problem rather than the units being inherently incompatible. (sony-asia.com)

Correct wiring and quick checklist (common mistake is plugging the wrong ends): connect your video source (Blu‑ray, set‑top, etc.) to one of the HT‑DDW7500 HDMI IN jacks (BD IN / DVD IN), then connect the HT‑DDW7500 HDMI OUT (often labeled MONITOR/TV OUT) to an HDMI IN on the LG. Turn the TV on to that HDMI input, then select the matching source on the Sony. If you plan to use BRAVIA Sync or HDMI control, check the receiver HDMI menu; temporarily disable HDMI control/CEC if the handshake fails. (manualslib.com)

If you still see no signal (as described by ), follow a simple isolation flow: 1) try a known-good, short HDMI cable (quality and length matter), 2) plug the source directly into the TV to confirm the source and TV accept the signal, 3) power‑cycle all devices (unplug ~30–60s) and then power on TV first, receiver second, source last, 4) try different HDMI ports on both devices and try lowering the source output (force 1080p/720p). HDMI handshake/HDCP and EDID mismatches are frequent causes and are fixed by these steps in most cases. ’s cable-quality tip is often the fastest fix. (orei.com)

Fallbacks: if HDMI still fails, use component video for picture (if available) and optical/coaxial or analog audio for sound until you can resolve HDMI. Also check for firmware updates on both units and, if needed, contact Sony or LG support with the exact setup and steps you tried. (manualslib.com)

which connection are you referring to? i believe HDMI would be the best way to go here.

Thanks. Yes i was referring to the HDMI connection. I could not get the signal when connected with HDMI. Any other ways.

Thanks again

are you sure you have a good quality cable? how long is it? there is no reason HDMI shouldn't work if both units have one. another way could be component i suppose, but i don't see why the sony hdmi should not work with the LG hdmi
