Subject: [TechAssist] Zenith TV SJ2779BG Relay Clicks
> Hi Everyone
>
> I have this Zinith TV Model # SJ2779BG , Service # SJ2779BG1 . When power
pushed relay clicks but does not turn on. One side of relay changed color
as a result of heat . I changed relay and C3526 , but did not help. All
fuses, voltage regulator and Horizontal Output Transistor looks ok. I
resoldered all the points on power board for possible loose connection no
luck. Any suggestion would be appreciated.
