Power Supply Trouble Shooting Notes:

2010/2011 models

Will not be run with the “X” or “Y” main disconnected. The SMPS will

shut down immediately. However if a meter is first connected to the
test point when power is applied it will read the correct voltage briefly
before shut- ting down.(You have enough time to check key
voltages)

CAUTION: Do not reconnect any connectors to SMPS or Y/X Boards

until power has been turned off long enough for Vs to drop below 10V
or damage will occur to X or Y Boards.

SMPS Over Current Protection

If a short circuit occurs on either the VS or VA voltage lines, the SMPS
stops operating, but should not fail. When the short circuit is removed
from the source line, the Power Supply will operate normally again.

Many SMPS Supplies are replaced needlessly!

Sample

“VITAL SIGNS”

When troubleshooting, It’s very important to first check Vs, Va, Vsc & Ve

If Vs is missing (0V), disconnect power and check for short. Use ohm
meter to measure resistance while disconnecting Y-Board & X-Board
supply feeds one at a time.
Turn Power On and Test SMPS with shorted connector removed for
correct Vs voltage verification. (It may only come up briefly but to full
level). Be careful not to reconnect power connectors until Vs falls below

10V.

If Va is low or missing, disconnect power connectors to Address Boards
and Check to see if SMPS Supply is restored. (Note Va feed normally
passes through the Y-Drive to the Address Boards (Logic Buffer Boards).

If Vsc is low or missing and Vs is OK, the failure is with the Y-Board

.

since the Y-Board generates the Vsc voltage from the supplied Vs.
If Ve is low or missing and Vs is OK, the failure is with the X-Board since the

Ve is generated by the X-Board from the supplied Vs. (Please note: In some

rare cases the Ve is generated by the Y-Board fed to the X-Board.)

Other SMPS Voltages:

Check Low Voltage feeds to the Main Board and other supplied Assemblies.

TROUBLESHOOTING VIDEO PROBLEMS

1. Verify Video Operation

a) Customer Picture Test (if available)
b) “Display” (If display is OK source is suspected)
c) Substitute with known good Source
(external DVD or Signal Generator)

3. Determine cause

a) If Logic pattern is NG; Logic

board, Logic buffers or

Panel are suspect.

b) If FBE patterns is NG and

Logic is OK; Main or LVDS
cable are suspect.

c) If both are OK it is likely a

source issue.

2. Using Test Patterns in Service Mode

Fast Track Troubleshooting Manual

ALIGNMENTS & OPTION BYTES :

1. Check/Adj. VS, VA, VE, & VSC according to Panel Label
and Diffusion test. (see bulletins for any special notes
before making changes)

2. Check/Set Option Bytes:

- ENTER SERVICE MODE -

a) Customer Remote: Power off; Mute, 182, Power On

b) Service Remote: Power On; Info, Factory

DIFFUSION TEST/ADJ. (cell miss-firing, older
units)

- Allow the unit to warm up 15 to 20 minutes

- Access the Burn Protect Sig. Pattern in Cust.
Menu.

-Adjust the Vs volts until screen errors are gone
in
both dark and bright areas.

- Adjust the Vs volts within +/- 10V on the panel
label.

SPECIAL NOTES:

See bulletin “Red Dots” for correction/

adjustments for this model.
