Bad/Faulty Cap? On the main board or power supply board? Happen to know which cap it is?

Re: Vizio service manuals

John CT. Do you have the service manual for a Vizio E390-A1?

Re: Vizio E390 A1 issue.

Anyone happen to know who makes U409? And what the pin out is as well as which leg does what (which one has voltage so on and so forth).

E390-A1. When plugged in, gets the white power light. No backlight, no audio, no picture. Have already replaced power supply board, issue remains the same. FOr the heck of it, tested all the video inputs using a Sencore Video Tester - still no video. Have heard that U409 goes bad. Also heard that EEPROM gets corrupted and that reflashing solves this issue. Main Board part number is: 756TXCCB02K042.
