Use of silicon or superglue on a coil next to the flyback that solved the problem in a similar model RPTV. Easy fixes first

Subwoofer makes noise like an untuned TV regardless of volume knob

I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

Darker picture and high pitched sound from back of tv. Also flickers.

Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.
