RCA LED32B30RQ only standby voltage

[pop70458]

Hi, I have a RCA LED32B30RQ and the only voltage I am getting is 5v sb. The 5v, 12v and 24v are dead.

Thanks in advance for the help.

use a 1K resistor from PS_ON to 5V Standby and see if the 12v and 24v are there

Measure PSON pin after you push the powet button.

I jumped it with a resistor and all of the voltages came up. The tv has no 24v, I read the board wrong they are 5v also.

Do as mmartell suggested and check PS_ON pin

"I jumped it with a resistor and all of the voltages came up. The tv has no 24v,"
So ALL the voltages come up but not the 24VDC? How about the 12V?
All the Voltages on this always on power supply is generated by the same power transformer, but the sub Voltages are fed through the electronics switches that are turned on by the PS-ON signal.
The main SMPS is fine.

The board doesn't have a 24v section, I made a mistake reading the board.

Geez am I the only one who is confused ? I think you are saying now that you have all the voltages so what exactly is the problem here ?

When i jumped it with a 1k resistor the voltages came up but it wouldn't power on. When i press the the power button i get no voltage on ps on.

Defective Main Board is my suggestion

I concur with Andrew.
