Do you have the model number available? It should be on the back or bottom of the unit. Before adjusting, clean the heads and verify that the tape is running at the proper height past each head. There are three head assemblies to inspect: the rotating video head, the stationary sync head, and the stationary audio head. The sync signal is on the top edge of the tape and the audio signal is on the bottom edge. If the sync head or an adjacent guide pin has come loose, that could cause tracking problems. Caution: the video heads are very delicate. They're located in the slots at the bottom edge of the rotating drum. Use a foam-tipped swab with straight isopropyl alcohol, and gently wipe the heads in the same direction as the tape goes (do not wipe perpendicular to the tape direction; you could snap the head off if it snags on the swab).

Could be you need to set the output volume on your receiver for the soundbar. Most receivers allow volume output for each speaker

Do you see a small fan close to it? Is it gunked up with dust? It could be the bulb but it sounds like it isn’t getting cooled.
