I'm looking for some assistance with troubleshooting a Vizio SV420M. It has the same symptoms as some of the other post here, Light operates normally, but no picture or sound..
All voltages except the 12V are working fine. The 12V pins read 1.9V. in my attempts to troubleshoot the fault i found that the Power supply is in fact producing the 12V at D908, but once it gets to the pins it's at 1.9V
Ive traced the 12V to pins 1 & 3 of Q910 but the pin 2 is showing 1.9V and that leads directly to the Connector pins.. any help would be great, I'm stuck. The images are stock images from shop jimmy Picture 1 shows the voltage points i have so far. My actual board will be posted when i get in. Thank YOu!!
