Vizio VA370M

[nlbailey]

I have received a Visio VA370M that is in partially working condition. Its symptoms were that it would take a long time to load past the logo and then it would work for awhile before glitching/freezing up and have to be unplugged. Then you would have to wait awhile before it could turn on again. Also audio worked through external speakers but not internal.

The previous owner tracked down two bad caps and removed them, but never got around to replacing them. Then the bad caps got lost along with what model/specs they were. So my question is does anyone know what caps I can use to replace the missing caps? I pulled an image of a board from ebay that had them to show which ones it is, so please take a look at the image. Thanks for the help!

Additional Information:

The board this comes from is a CBPF9D1KZ5 main board.

This board is also know to be used in Visio E370VA

Re: Vizio VA370M

Ok, so I was able to get some capacitors and get them soldered in place. Now I am able to get the TV to turn on and display the Vizio logo, but it just sits on the logo. I can turn it on or off using the remote or the panel at anytime, but that is it. I see no more bad caps anywhere. What should I check or what pictures should I upload.

1) Post clear focused top down pictures of all your boards following my sig file below exactly. We want the picture compositions like so

2) Many Vizios have failing or failed voltage regulators on the main board. I would test them all to verify they are okay.

What caps did you use? The top right corner one(in your pic) is a 680uf. and I believe the other one is 35v. I think that are both the same judging by the size.

Re: Vizio VA370M

Okay, so I was finally able to get images of the boards. They are below. As for the capacitors I was able to track down that they are 1000uf 35v. As for the exact specs I was unable to get a clear answer, so if anyone has an exact board please feel free to tell me manufacturer, model, etc.

Re: Vizio VA370M

Forgot to mention in image 1279, the back of the main board, to the right of the image there is the backside of one of the header connectors. The top left pin has solder on it that connects it to the pin located below it. Is this normal? It didnt seem normal to me but didn't want to make any changes without asking first.

Re: Vizio VA370M

As I said the cap in the corner is 680 on other boards I have seen (1000 should be ok though)
Solder Blob - I dont think it will make a difference whether it there or not. Pictures are not quite clear enough but looks like both pins are for 24v?
Does the on screen menu come on? is there any volume? Have you got a source
perhaps try with a dvd player. It may be stuck looking for whatever source it last had
so try as many as you can. Some Tvs will reset if you hold in the power button whilst plugging it in?.
Have you started looking at the voltage regulators as retiredcaps suggested
Check any fuses you can find and post results in ohms.
Try for clearer pictures

This is the connector between the main board and T-con. Don't see it labeled at all. Have to find my meter to see what it is.

The Television turns on, but only shows the Vizio logo, nothing else. No on-screen menu. I have tried connecting multiple sources. Composite, VGA, Cable. Still nothing.

Tried to no avail.

I am going to go look for my meter right now. May need help checking these correctly.

Think I have the wrong connector better post a close up pic of the area you mean

Re: Vizio VA370M

Here are some more images of the board layout and the specific connector in question. I found my meter, but unfortunately after moving recently it appears to have not made the trip successfully, so I will be picking up a new one.

Re: Vizio VA370M

Ok when you have a meter check the pins - cant really tell from the pics if it bridges or not. If it looks like a splash remove it - if it looks like its always been there leave it
or remove it and try it and if no difference re solder it.

Re: Vizio VA370M

Did you ever find the problem. I have one with the same issue.
