If there is no video on a 2010 Plasma TV
or the video is so distorted that you can’t
see the menus, you can “force on” the
SMPS and get the test patterns that reside
on the Logic PCB to display using this
method:
1. Make sure the AC cord is disconnected.
2. Disconnect the wire harness going
from the SMPS to the Main PCB, and
then short the PS_ON and GND pins
together.
3. On the Logic board, carefully short the
two pins with the highest numerical
value (3 and 4 in a four pin connector
or 5 and 6 in a six pin connector).
4. Connect the AC cord.
When you power the panel on, the PDP
will automatically “play” the internal test
patterns stored on the Logic board that
you could normally access only through
the service menu.

Netflix Blu-ray Bug Fix with 1020.1 Firmware
Michael Vigliotti
Product Support
We've released Firmware Version 1020.1 for models BD-C5500 and BD-C6500. This Firmware Version fixed the
'Stretched Video' issues customers were encountering when streaming 4:3 movie titles from Netflix. The video would
stretch to wide screen and this would distort the movie stream.
We've noticed the following after installing firmware version 1020.1:

After you install the firmware, the player will power off. When powered back on, the player displays the Home Menu.
Customers no longer have to go through the initial screens or setup their network.

The default 'TV Aspect' is set to 4:3 Pan-Scan. If this is not changed to '16:9 Normal', customers will still see
stretched 4:3 Netflix streams with some titles. YOU MUST ADVISE CUSTOMERS TO CHANGE THE 'TV ASPECT' RATIO FROM 4:3 TO 16:9 NORMAL to view 4:3 Netflix titles.
If customers leave the TV Aspect set to 4:3 Pan-Scan, all 16:9 content will have the extreme left and right portions cut off.
To change the TV Aspect Ratio, follow these steps:
1. Using the directional pad on your Blu-ray remote, move to Settings on the Home Menu, and then press Enter.
2. 'Display' is automatically highlighted. Press Enter. 'TV Aspect' is automatically highlighted. Press Enter.
3. Using the directional pad on your Blu-ray remote, move to 16:9 Normal, and then press Enter.
4. Now the customer can select any 4:3 Netflix stream and it will stream correctly.

Checking Plasma TV Y Buffer (Scan) Boards
Bob Shoemaker
Assistant Manager, Regional Technical Trainer
The supply for the scan board is called OUT H and OUT L. They are the scan pulses developed on the Y drive and have
a DC difference of about 150 V that is determined by the Vscan adjustment. There is no ground reference on the scan
board. There is also a 5 V supply for data processing. It too is referenced to OUT L. Everything on the scan board is
riding on the pulses.
You can check the scan boards for shorts using a DVM on diode check setting. Measure from OUT L to OUT H and 5 V
to OUT L using both polarities. There will usually be a dead short if defective.
OUT H
OUT L
5V
The boards on some models may not be marked. Using the PN42C450 as an example, if you see many traces of the
connectors tied together; you are looking at the OUT L. The OUT H will have 2 or 3 pins connected. The 5 V has a large
trace with 1 or 2 pins.
OUT L. All but the outer
two pins are connected
together.

OUT H. 2 pins with a
large trace.
5V. Single large trace.
