Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
I performed this test on the new inverter board, it was evenly lit up all across, so the inverters are good....

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
Ordered a new inverter board since it was relatively cheap, the issue still persisted. I went ahead and dug deeper and opened the panel up to the CCFL's, and all appear to be fine. I'm not sure if they can appear to be fine and not be, but I will attach a picture of them all lit.
Not sure what to do from here

Re: Olevia 232-S13
Super old thread, so I apologize. Kevin, were you ever able to locate a service manual for this model? I have looked to no avail, and I found a manual on Tom's site, but it's for a 232-S12, not S13.Leave a comment:

Andrew, I will research the EEPROM and Flash IC for this TV, as I'm not certain right off hand where those are located. Thank you again for your help and suggestions.

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
I will look into that. I have a 42" TV with good bulbs just a literal hole through the screen from a toy, if I read correctly on troubleshooting two seconds to black I can use that bulb to do a swap and see if they're all lighting. I think the inverter board for this TV is only $22, if it doesn't fix your TV are you allowed to return? I was leaning towards Ebay, but Shopjimmy.com has one as well. Thank you

I will check into that bud, thank you for all of your help and patience. I may also try to price a CCFL and see if it's within reasonable price range as well before proceeding since that may be what I"m looking at. Thank you again so much....Leave a comment:

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
I'm going to upload a photo of the logo when it pops up without the cord connected, I'm not sure if this is any count either of how it actually appears, or just because of the cord, but maybe it will shed some light.
The images look garbled/discolored to me.. that could have something to do with the connector not being connected, I'm not sure how it all works.. just thought it might add insight or it may be nothing....Leave a comment:

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
They all equally flashed the same brightness, I was also able to see the Spectre logo in doing it as well. What was so shocking with unplugging connectors was when this 2 seconds to black is happening, it doesn't even seem as if it is Literally 2 seconds it just flashes and it's gone, but when I unplugged the connector the logo was fully there. I'm thinking it isn't the CCFL's, through reading the 2 seconds to black troubleshooting guide I read a spare bulb doesn't have to be the exact size so if all...Last edited by juicedlime; 10-01-2014, 09:36 PM.Leave a comment:

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
Ok, so I figured I had nothing to lose, since it's already out of whack anyhow, so I just started taking a plug off, powering on seeing what happened and plugged it back in then unplugged another and so on, just seeing what would happen.
Well, here's what happened, I pulled a connector that ran from the Inverter Board to the Main Board and it says CN4 on the main board, I am pretty sure I tested these points in CN4 with bud and it checked out, so I thinking the problem lies within the Inverter Board (the one...Leave a comment:

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
Jumping them over and powering up only did the same thing it's been doing, flashing the logo then going black. So if the bulbs are bad, then my test didn't work and I need to get a spare bulb, or it's something else.

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
The inverters tested alright, I will go back to the Troubleshooting 2 Seconds to Black and attempt to test the CCFL's. I have a tv with a busted screen, that still came on, could I use a bulb out of it to do this?
I'm going to try to jump the bulbs over, if I hit one and the screen stays on that should tell me which one is bad, if one is bad, or so I'm hoping. Will report back....Last edited by juicedlime; 10-01-2014, 07:49 PM.Leave a comment:

Any other ideas? I am more than willing to do more troubleshooting steps to get it up and running.
Thank you for your time

Re: Vizio VA370M looking for firmware bin file
Use the LiveChat option, through my lurking I have read many have had success with letting LiveChat know the issue, and even out of warranty, Vizio offered to mail them the firmware to fix the issue, or offer to send a repair technician to their house free of charge with 90 day warranty on that repair. Goodluck...

Thank you again budm, and john. Sorry for my lack of knowledge, am grateful I am learning though.
I disconnected the cable, tried to turn the TV on and nothing. No Sceptre logo or backlights glowing through the holes of the chassis. The blue LED light is on on the front of the TV, but no backlights....Leave a comment:

Is there anyway you can circle the T-Con on one of my pictures? Or is it the same thing as the main power board (the green one)?...Leave a comment:

Re: Sceptre X405BV-FHD3 Powers on, logo appears, then shuts off
Thank you, john. There is no sound, however when I am doing this it isn't hooked up to cable or anything at the moment (not that it would be an issue at all to hook up and check). From testing last night with it plugged up, when it powers on you can see the blacklights light up quickly, then go out, and the front blue LED remains on. I am attempting to find Service Manuals or datasheets (no luck) and try to keep reading over How To Guides and figure some of it out on my own as I hate to feel bothersome...Leave a comment:

My apologies, budm.
I didn't realize they were that badly out of focus, I hope these are more sufficient, I took them outside to try to get a better visual. I appreciate your taking the time to help me and for your patience. I am very grateful....
