OK, with the info above being CORRECT -- here are your Test points for ALL TESTS that we may run.
SET your voltmeter to the DC Volts setting --Thats the V with the two FLAT lines above the V. Or the Vdc setting....
This picture shows the 5 Volt Standby test pad, it shows the POWER ON Test PIN (4th from bottom of the plug)
And....Never trust the picture over your OWN EYES. If you see the Power on Pin elsewhere, they may have modified the board. Same with the 5Vsby or standby 5 Volts.
The key is the board IS MARKED with the INFO. How do you think we field techs pull the back cover off, pull out our meters, test a few points....and then tell you what the problem is ?
Because the GOOD manufacturers MARK the test points and they mark them LOGICALLY.
5vsb....P-on ....short, and sweet.
Now, the BLACK test probe can simply be touched to the metal backside of the Plasma Panel because that's 0 Volts or Ground /GND.
All voltages are measured with the black test probe connected to that.
The RED test probe is the one you use to measure the 5 Volt standby FIRST.
Gotta have that at 5 Volts DC when the TV is plugged in. All the time.
The P-on line -- If the micro is WORKING, that P-On line should measure 0 Volts when OFF, and 5 Volts when ON.
Picture too small? Look at the lower right corner of IE 8 -- That + 100 box will let you magnify the Picture for a better closeup of the picture.
Sorry, the picture isn't from my Sony 14MP camera. It's probably from a 2MP camera.
