Re: Directed Audio 2400D powers on into protect.
Yea,I agree about the top cap,but it looks like it was probably installed that way.I agree that I should probably change it,but like i said,I have no idea how to unsolder it lol....

Re: Directed Audio 2400D powers on into protect.
Pulled it out of the heatsink and it has 67.2 volts on the large 4 caps.And of course now it isnt going into protect.So it appears this is going to be one of THOSE problems.I cant even replace the damaged cap because of the mountain of solder on the underside of the board.All I have is a 40/20 watt solder station.And yes,it is a ClassD amp.Last edited by ktulu909; 03-30-2012, 09:54 AM.

Re: Vizio VS420LF1A No picture/backlight
See my thread.The main board sends the signal to the PS to tell it to turn on the 12 and inverter lines.
You have a different board than I do,but I would look very closely at the regulators as it turned out to be a single regulator on mine that was keeping it from turning on.

Re: Vizio VX42LHDTV10A stuck in standby after going haywire.
That was it everyone.Thank you so much for all of your help.Repairing this TV has been a very rewarding experience as all I have done in the past is simple board replacement stuff before.
My mom thanks you guys very much for your help,as do I.Its a 5 year old 720P vizio,but to my mom its her main source of entertainment.

Re: Vizio VX42LHDTV10A stuck in standby after going haywire.
Heres the best I can get. For that matter,it looks as if U8 is the only one that has a trace that leaves the output.Now Im really lost....Last edited by ktulu909; 03-20-2012, 06:24 PM.
