Thanks Randy,
I saw that in WinStips also for the model SRT2027 and didn't think it would
apply. The
first band of both resistors R574 & R575 is red so I found it a little
difficult to get to
1.5k or 470ohms so I assumed the chassis was different. This unit also uses a
2sd2578 for
the HOT, unlike the SRT2027 which uses a 2sd2634 or apparently a 2sd1888 for a
sub.
Have you personally used these resistor values in the 6427TA chassis? Whatever
the resistor
value was before got quite hot and maybe that was the problem, incorrect
resistance.
Anyone with a print for this one, or any other input out there would be most
appreciated.

Hi Bill:
D571 is ERB44-02 or NTE552
Make sure that you replace R574 with a 470 Ohm @ 2W

From WinSTIPS......this should be the same chassis

Dead. Q571 Horiz Out Xstr Shorted Plus Resistors Burned
Replaced The Parts Listed Below. What Really Dogged Us Was The Fact That
Sears Had The Wrong Value For R574. They Listed It As A 1.5 Ohm But It Was
In Fact A 470 Ohm. So We Had This Thing Fixed The Whole Time! With The
Wrong Resistor The Unit Would Start But The Pix Was Skewed Way Off To The
Right.

All I can find is 6427TE
I checked that and 6427TD and R574 was not listed...so I don't think they will
be close
enough.

Have a 27" 2000 year set here that has a problem in the area of the HOT Q571
(2sd2578) which
is short E-B.
R574 and R575 are burned beyond recognition, other than to guess that they are
2w flame
proof resistors
with a red beginning band.
Also D571 burned in two and the board area just below these parts badly
charred. Need the
values of these
parts and appreciate any help from anyone with experience on this particular
chassis.
TIA
