After some advice if possible.

Bought a HT-MT500 soundbar. Connected to an LG tv, LG43UH620V.

At the start it worked fine, sounds sync’d with tv etc. Am now having a few issues:

a. Soundbar no longer turns on automatically with tv

b. Takes an absolute age to turn on - message “Please Wait” keeps appearing for up to 5 minutes then soundbar turns itself off with message “Auto Standby” showing

c. If soundbar does finally turn itself on the sound does not match with tv

Appreciate any advice someone might be able to give.

Thanks
