Projector image dim, yellowish or blurry

Blur is usually focus, placement, keystone or condensation; dimness is usually lamp age, an eco/low light setting, or a dirty filter forcing reduced output. Internal optics are not field-serviceable.

Soundbar won't turn on with the TV, or TV remote won't control its volume (HDMI-CEC)

One-remote control depends on HDMI-CEC over the ARC/eARC cable. Disabled CEC, the wrong HDMI port, an optical connection, a poor cable or a TV update that switched settings off cause nearly all of these calls.

Soundbar audio cuts out, pops or drops with movies/Atmos (ARC/eARC)

Dropouts usually come from an unstable ARC/eARC handshake or a format the chain doesn't handle well. Work through cable, firmware, CEC conflicts and the TV's digital audio format; optical is a stable fallback without Atmos.

Projector won't turn on or shuts off (reading the indicator lights)

Projectors protect themselves: overheating, lamp at end of life, and lamp-cover interlocks all stop the light source. Read the indicators against the model's table, then fix airflow, lamp seating or lamp life.
