Subject: [TechAssist] A couple of slightly wierd fixes today
ctc203J10 and others like it I'm sure, had squealing from the smps
transformer and area. I siliconed the beads on the legs of the diodes
right next to it. I thought that took care of it. Next day--similar
symptom---no where near as loud (beads were definetly ringing) Had to
pull the HDT and take off the black plastic. I put some varnish in the
cap of a spray can. Turned the HDT upside down and put it in the
varnish for a while. (tried momentary varnishing and it didn't work)
Let dry and reinstalled---no problem now. I've varnished a lot of yokes
over the years--and a few smps transformers---but never a HDT.
Next-- Toshiba cn32h95 tac9810 pic was going dark. I made assumption
of bad tuner based on that I've replaced a few before (ela12lx5 $12.41
tritron) and resolder the can directly behind it. Still had same
symptom. Found pin on micro ta12-- (uhh forgot--and all ready put it
together) I think ta1295? Whatever---found a pin that was never
soldered from the factory---how it worked at all was amazing. This is
something most people would find (that is people on this list) I just
thought I'd point it out.
