Question about Standard (CRT) Televisions
HUMMING/CHATTERING NOISE WHEN TV TURNED ON. SOUND SUBSIDES WHEN PRESSURE APPLIED TO TOP OF COMPONENT. IS THIS A RELAY ISSUE.
TROUBLESHOOT TO COMPONENT:
MODEL: SANYO AVM-1903
YOUR ASSISTANCE IS APPRECIATE.
I got a 13" Sanyo AVM-1304 with the same problem today. Found The picture and sound were okay, but the relay chatter was very loud. Found a couple of notes on other forums saying that changing the filter capacitor would fix it. (On that model it was C022, a 470MF 25VDC electrolytic cap). I changed it about an hour ago and so far so good.

Confirmation: Lee2fixit's solution also worked on a Sanyo 19" TV Model DS19580with 'buzzing relay'. Chassis carriessimilar relay (Type DG1U 12VDC II TV-5 8A 250V~ also by DEC) at location RL601and a 25VDC 470uF electrolytic cap at C622. After confirming the relay was sound and finding no obviously faultedcomponents tied to it, replaced the cap. Bingo, normal operation and a quiet relay. Will post a follow-up ONLY if the fix failsbefore the rest of the TV .. it's almost10 years old after all. Thank youLee2fixit and FixIt.com.
