Solution
* With a voltmeter, measure Y3.
Proper resistance should be between
5 - 60 ohms. Replace Y3 if resistance
is outside of those values.
* Verify wiring for C37STL (BL/BK,
TCON J4-11) and check for open or
short circuits.
* With a voltmeter, measure Y4.
Proper resistance should be between
5 - 60 ohms. Replace Y4 if resistance
is outside of those values.
* Verify wiring for C36STR (BL,
TCON J4-12) and check for open or
short circuits.
* Using a voltmeter and with the
system turned OFF, check the
resistance between TCON J5 pins
9 and 10. Replace TCON if
resistance is more than 5 ohms.
* Check P79PWR (BK, TCON J5-9)
and P23PWR (RD, TCON J5-10) for
open or short circuits.
* Inspect PCON J15 pins 11 and
12 for open or short circuits. Using a
voltmeter, set to diode test mode and
make sure the diode tests ok with the
anode at pin 12 and cathode at pin
11. If test fails, replace the PCON.
* Inspect TCON J5 pins 11 and 12 for
open or short circuits. Using a
voltmeter, set to diode test mode and
make sure the diode tests ok with the
anode at pin 12 and cathode at pin
11. If test fails, replace the PCON.
* Check P23RET (BK) for shorts to
ground or power.
* Check J1, Bank Power, on TCON is
making a good connection.
* Verify pin 1 is grounded
* Verify pins 2, 3, 4 are 12V
* Replace TCON
* Check J11, Bank Power, on PCON
is making a good connection.
* Verify pin 1 is grounded
* Verify pins 3, 4 are 12V
* Replace PCON
