Transistor for TV problems

Re: Transistor for TV problems

No pic and probably no backlight but will have the 5v STBY as set "attempts" to power.... So will be missing the 12v and 24v.

Can you give me a close up pic of the connector that goes from the PSU to main (Top left of your image) so I can see the labels for voltages please.

Need to confirm voltages at this connector to confirm the missing voltages and see what's going on.

backlight on at all?

I get 2 pages on E470VL

Re: Transistor for TV problems

It's a Vizio E470VL, picture on the TV doesn't come on but the orange standby light changes from orange to white when I press power on the TV.

Dare I even try to get involved as my LCD knowledge is slim but if the front led changes colour have you then checked what DC voltages are present on the PSU at the connectors?

Does it remain white? If you get a flashlight and try to put some light on the TV can you make out an image?

there maybe other posts on Vizio E470VL. tried a search on model yet?

I had the negative lead in the middle, I put the positive lead on the left side It tested OL and on the right side it tested .259

maybe explain to every one the fault + Tv model photos of boards etc

Chances are that FET is ok

Re: Transistor for TV problems

How is it tested out? Shorted? What circuit section is it in?

I'm a noob when it comes to these types of things, I have a transistor that i tested, it seems to be a bad one. I'm trying to order a new one from Amazon but i don't know which one I should get, can someone please post a link from Amazon on which type of transistor I should get,here's a pic of the bad transistor.
