Bad Power board LM004 rev.3 for DLC9A
this board does not have any name . But thru search found to to be a Sceptre product. The monitor will turn on then go off. No back light or with flashlight in back ground, but the green light on the front keeps blinking. Can find NO paper work on this board from Sceptre or internet. Need help to repair or replace.

Re: Bad Power board LM004 rev.3 for DLC9A
Clearing out the contents of my camera card and found pictures I took of this very same board. I can't find the specs for the two capacitors that have popped though. I am trying to figure out which product also uses this board. I'm confident I didn't have a Sceptre Komodo.Attached FilesComment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

I then got online and found this great site! ....read many troubleshooting tips and this... -

I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
