Re: Panasonic dp42d23

Hi Dick I will do that and get back to you but does anybody know where I can get a schematic for the led dp42d23 tv .It would appear that whatever is supposed to generate 12 vdc to appear at these test points on the power supply is defective .There is 0 voltage
at these test points so I came come to the conclusion my first issue is in the power supply board .

Hello superbob8,
This is not necessarily the case. Any number of non related power supply faults could instruct the mainboard to keep the power supply in standby mode by not issuing a Power On signal. Knowing what the voltages are on the pins tends to guide you to where the fault actually is.

Hello superbob8
In order to help you and without the TV in front of us and having now previous knowledge of the TV you need to provide as much information as possible.
The connector I highlighted, can you list the names of the pins and what voltages are on each of them in turn. The name of the pins are written above the connector but I cannot make them out from you picture.

If you have 5v but not 12v then we need to know what voltages are on those pins. Please can you list all the pin names and what voltage you read alongside the name so as to give us a clue if it is a mainboard or power supply fault.

on every pin that is supposed to have 12 v there is 0 voltage every pin that shows 5 v has 5 volts
