Sorry posted this in LG TV forum by mistake.

M-in-law was recently gifted a new LG TV. I connected her old Panasonic DVD recorder DMR-EX 89EB to it. There seemed to be only one way to connect it. Seemed to be working OK. Checked it recorded from TV. Couldn't get her Magic remote to control it but she wasn't too worried about that. We now find the sound on playback of her TV recordings is either muffled, sounds like bad static or just plain distorted. I have changed the dmi cable but made no difference. Is it possible there are some settings not configured correctly or is it just a coincidental death of the Panasonic. It is around10 years old.

Is it receiving the correct audio signal via HDMI on the tv?

Bad news I'm afraid.

This is a classic symptom of failure of IC3001 (LV7107)

Specialist repair only. 100 pin chip.


Sometimes (but not always) it is possible to find another sound output still working OK ( Scart or Phono) if it is possible to contrive that.

Will try SCART. Thanks. Do you think it just an unlucky coincidence that this has happened when connecting new TV?

Every single input and output on the unit is connected directly to this chip.

There is some anecdotal evidence that electrostatic discharges from making and breaking connections may be the cause of this problem... but it seems to be much more prone to do so when the machine has aged, so it may be that problem in combination with aging power supplies.
