X-Main Y-Main SMPS
Power Supply Trouble Shooting Notes:
2010/2011/2012 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. .
Over Current Protection
For the SMPS Power Supply... 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!
Vs & Va Vsc
SAMPLE VIEW & READINGS
Ve
. VITAL SIGNS check Vs, Va, Vsc & Ve
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 short connector removed for correct Vs voltage verification. (It may only come up briefly but to full level). Again be careful not to reconnect Power Connectors until Vs falls below 10V.
If Va is low or missing, disconnect Supply Feed 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 was OK, the failure is with the Y-Board
.
since the Y-Board generate the Vsc voltage from the Vs supplied by the SMPS. 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 Vs supplied by the SMPS. Please note in some rare cases the Ve may be generated by the Y-Board feed to the X­Board.) 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 B. “Display” C. If display & Customer Picture Test are OK source is suspected D. Substitute with known good source and cabling.
2. Using Test Patterns in Service Mode:
Customer Remote
A. Power off B. Mute, 182, Power
Factory Remote:
A. Power On B. Info, Test
3. Verify Echo-P Patterns
4. Verify Logic Patterns
If Logic Patterns are OK and Echo-
P are noisy, replace the defective LVDS Cable or Main Board.
If Echo-P and Logic Patterns are
both noisy check for specific on screen noise error to determine failure. (next slide)

Fast Track Troubleshooting Manual
ALIGNMENTS:
1. Check/Adj. VS, VA, VE, & VSC according to Panel Label
and Diffusion test. (see bulletins for any special notes before making changes)
DIFFUSION TEST/ADJ. (cell miss-firing)
- 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.
-
NOTE: Diffusion may appear with aging panels. New panels problem
2. Check/Set Option Bytes:
.
NOTE: Verify correct settings with latest tips!
with Diffusion consult bulletins and/or report
