Vizio VX42L HDTV10A no ps on voltage
I have a Vizio VX42LHDTV10A with power supply #0500-0507-0330 and main board #3642-0252-0150. The problem with the TV is an Amber LED. I have trouble shot the power supply and unplugged J1 from the main board and used a resistor to turn the power supply on PSON to 5V. All voltages check good from the power supply. When connected and turning the TV on I get no 3.3v to the PSON pin to start the power supply. On the main board I have 5v standby and 3.3v on U8 output. Fuse 1 and 2 ohm out as good and have 5v on F2 but no voltage on F1. I checked some of the other voltage regulatorS and they seem to...Last edited by neatpathfinder; 02-16-2016, 10:03 AM.
