Vizio VX37LHDTV10A

Re: Vizio VX37LHDTV10A

The picture will have to wait until morning.
The problem is that it shuts down to fast to be able to take a couple of measurements.
I will have to start it up a couple of times until I can measure all the regulators.
What is weird that I'm measuring the outputs from the PS and I'm not getting anything while the led is white.

Use min/max on your new Fluke 87V.

Re: Vizio VX37LHDTV10A

It's not that fast, I can still take like three measurements if I'm fast, but thank you for the suggestion. I knew that one day these extra features will come handy. By the way I have got a nice C550 bag as a promotion item from Fluke and I'm selling it, asking $55 for it, so if I can sell it for $50, my meter will be only $200.

Re: Vizio VX37LHDTV10A

I'm not feeling good, so I couldn't do any measurements, I have just took a couple of shots with the phone.

Re: Vizio VX37LHDTV10A

I had a breakthrough with mine, though not sure what I did that "fixed" it to a point.
I guess I have tried using budm's suggestion to use the min/max on my meter, but course I didn't know what I was doing because it was maxing out with OL, but after this the TV stayed on with white logo.
My primaries were 1.6xxKOHM and the secondaries were 6.1KOHM except T1's which was 158KOHM.
So I guess this is my problem.
Now where can I find this transformer?

Re: Vizio VX37LHDTV10A

Can you post the pictures of both Inverter boards? I want to see if they are the same as what I have at home. you are talking about the inverter transformer right?

[tibimakai]

Re: Vizio VX37LHDTV10A

I have only one board on the left side.
Now that I have put back the board in it's place, I'm getting even higher value.

Re: Vizio VX37LHDTV10A

Ah, Darfon inverters - these fail like nothing else - and it's usually the transformers. Enter the part# into eBay to find replacements.

Re: Vizio VX37LHDTV10A

Now I remember that Bill said the same thing. By the way what's up with him?

From the auction ...

"If you have a failed 4H.V1448.481 inverter board then there is a good chance one of these is bad. If you have an ohmmeter you can find out which one is the problem, simply measure the resistance between the two terminals at each bulb connector and they should all read very close to the same value, about 6k, one will have a higher or lower value indicating a failure. I can not guarantee that this transformer is the only problem, but on the boards I have seen it was always T2 or the second one from the top and replacing it fixed the board."

Re: Vizio VX37LHDTV10A

Wow, thanks for that. I guess only the first number/letter combination matters(6010B), right?
The meter it's awesome. I'm trying to sell a C550 bag(which was free with purchase) for $50 to drop the price of the meter even more.
Next on my list will be a Weller WESD51 station

Re: Vizio VX37LHDTV10A

The two VX37L I have uses two Inverter boards, the main board and my power supply (the connectors are the same as your) are not the same as you either.
Darfon is rally known for using bad transformers.

Re: Vizio VX37LHDTV10A

I have purchased that transformer that retiredcaps posted(thank you again) and I will see if it fixes this TV(finally). I'm fixing way to many Vizios, but they are easy money.

[budm]

Re: Vizio VX37LHDTV10A

How about the other two power supplies that you bought and they tested out bad when you use the lamps for testing?

[tibimakai]

Re: Vizio VX37LHDTV10A

I'm thinking about fixing them, but if I remember well I wasn't getting 12/24V from those. Most likely it's a primary side issue or again could be just some capacitors blown like in this one.
Do you want to help me fix those?

[tibimakai]

Re: Vizio VX37LHDTV10A

Finally I fixed it!!
I have replaced that T1 transformer and all it's OK.
Thank you all for helping me, specially budm.
Fixed 19 TVs since February(2 plasmas and 17 LCDs).
Tomorrow I'm getting a Weller WESD51 soldering station, sweet.

Next, a workbench. 72"x36" adjustable height shop top workbench.

Re: Vizio VX37LHDTV10A

Great news finally! So where did you get the transformer from?

[tibimakai]

Re: Vizio VX37LHDTV10A

I have purchased the one retiredcaps posted above.

[budm]

Re: Vizio VX37LHDTV10A

I hope it will last since it is used, not new transformer.

Re: Vizio VX37LHDTV10A

The original ones are used too. The next owner will find that out.
