Question about Standard (CRT) Televisions
Transformer do not output voltages, d1710 and other components are ok, 4.8k ohm (10watts) is hot, no shorts on the B+ and other circuits.
SOURCE: Sanyo ST-21G1 dead set
There should be a small valued cap in the primary side (22ufd?) at 250V. Check that. Also, look for other small caps int he range of 2.2ufd with 200V ratings in the same general area.

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.
