Delta DPS-199ap a Rev:2 cap value for C913 location(For a Vizio L32 HDTV10A)

[209ITek]

Ok, I got this Vizio L32 HDTV10A for dirt cheap($10) and the problem is a blown cap on the Power Supply (Delta DPS-199ap a Revison:S2). If I knew the exact ratings for the blown cap, I would repair it instantly. Please someone direct me to a schematic drawing of the Power Supply and/or if you know the value of hand. Thanks in advance.....

Hopefully these are better images of the location on the power supply....I circled the area of the location of the cap....The cap was so blown that I couldn't get no specs from it, it's a disc type....

Hope these are better pictures.....I inspected the whole power supply board and the other components of the TV and they seem fine....Wish there was a more complete service manual of the Vizio L32 HDTV10A.....

That looks more like someone cut it off... because ceramic caps do not just disappear like that with two little stubs of wire left.

If it really did explode, there should at least be fragments of it lying around.

I agree with b700029, unless you trimmed off the lead and there were more parts of it lying around, it looks like this was cut out deliberately.

It looks like this is part of the gate drive circuitry for the main SMPS. With the part numbers of the SMPS controller and the power FET we may be able to make an educated guess for the proper value.

Schematics for Vizios are hard to find. Many TV manufacturers turn to a subcontractor to design and provide the power supplies, schematics for those supplies are very hard to find.

I trimmed it off to clean up the area. The cap was so blown, only a fourth of it was left.

Do you mean the Voltage Regulators(ie. Mosfet) on the heatsinks and the IC chips on the board? The ones in close proximity to the blown Ceramic cap.

I might have to buy it to have a reference board. I would glady buy a schematic drawing of the Power Supply Diagram for $10, if it was available..

Don't know if this will help out, but here's the back side of the PCB....

I got the TV non functioning. It did look like it blew up, only a quarter part of the cap was left and I couldn't find the rest of it, with at least a label on it.

You might try sending the e-Bay seller a message. Explain to him your issue and ask him if he could either take a close up picture of the part and e-mail it to you or if he would read the information on the component in question. Hopefully you can get a response.

I was thinking about that. I give it a try. Otherwise, I'll probably buy it if the seller isn't willing to do that.

Don't buy a non working board for $18, wait a week for it, and still have the problem. If you just spend exactly $40 more ($50 Price $8.50 Shipping), you can get a working board. Just slap it in and go with it.

Your time at home is worth more than $40.

I've seen working one's for $40 to $70, but most of them are out of stock, if not all. There's ones that are $100 to $110, which is not what I want to spend. I would like to get the TV working asap, but I might just have to play the waiting game for it....

I forgot to mention that it was on ebay. I just did a search for DPS-199ap and found a board that was $50 with $8.50 shipping.

That's for a "DPS-199ap b" model, the one I'm looking for is "DPS-199ap a"...Thanks for looking for me, really appreciate it....The power supply I have has a part # of 0500-0507-0180. I post the Revision wrong, it's S2, not just 2.....
