Coppell TV Repair LLC is offering a repair kit for a failure we have seen and resolved a number of times in power supply board 0500-0407-0680 / DPS-280LP shown on the picture  and used in Vizio VO47LFHDTV30A and possibly other models.

Note this kit targets particular failure we have seen and it is limited to the hot side of the standby circuit alone.

Other vendors (like SJ) may offer repair kits that contain a broader range of components, but (at least of the time of creating this listing) they did not have all the components neeed to resolve the particular failure we've seen.

FAILURE SYMPTOMS

TV totally dead, no +5V standby output from PSU even without main board connected to it (no load).

Capacitor C901 may have signs of burning (see image), Q901 may test out of range, R901 (under heat sink) may be open.

If any of those are on your board then you need this repair kit.

Kit contents

Brand new replacement components for Q901, C901, R901, R902, R906, IC900, ZD725 (rarely bad), R908 (rarely bad) and possibly others (if we find out more is needed).

If you receive components that you do not recognize please contact us.

Difficulty level

Medium to hard. Replacing all buth IC900 is relatively easy, IC900 is an SMD component and requires more skill and attention.

Patience and attention are always recommended.

Improper handling may cause additional damage. If you are not certain you can undertake the service consider using our repair services instead.

SHIPPING AND HANDING

Products will usually ship on the next business day after purchase is placed and paid. Unexpected delays may occur. If you do not receive a tracking number or message from us within 3 business days after purchasing please contact us.

When shipping method is specified during payment it is our first choice to utilize that method for shipping.
Yet sometimes it is not possible or may result in delays, e.g. a late Friday FedEx shipping of inexpensive and durable product may have a chance of being shipped in Friday than the following Monday; in such cases we reserve the right to substitute FedEx Ground with USPS Priority and, in some very rare cases, USPS First Class service. If shipping costs differ significantly you are in your right to contact and request price adjustment.

When shipping option for the order is "Free shipping" we will usually utilize cheapest available method.
See below for important disclaimer regarding the USPS First Class Mail packages.

    We do not advertise delivery time and do not take responsibility for delays to packages as long as tracking information proves they have been shipped in a timely manner by us.

    Be advised that USPS does not take responsibility for neither shipping costs nor monetary value of packages sent with USPS First Class deliveries - both domestic and international.

    When choosing "USPS First Class" or "Free shipping" delivery options you agree to hold us free of claims against loss of value should your package gets lost in the carrier system as long as the tracking information shows the package was delivered to and accepted by the carrier in a timely fashion.

    WARRANTY CONDITIONS

    Coppell TV Repair LLC does not guarantee that this product is all that is needed to resolve the problems with your TV.

    Most of the repair kits we offer are based on first hand experience servicing boards at our repair facility. 

    Over time they may get expanded with our own experience or information from manufacturer service bulletins, customer feedback etc.

    Yet failure can be unique and there can not be guarantee that what has worked one, ten or even hundred times will also work the next one.

    Just as important, every repair involves about equal portion of quality of parts and quality of worksmanship and as we have no control over the worksmanship quality unless we are the ones performing it we would be unwise to provide warranty of the products utilized by that worksmanship.

    As such, no warranty is offered on this product once the components in it are soldered on a board.

    If you would like warranty please see if a REPAIR SERVICE is offered instead of a kit. Unless otherwise noted all our repair services do come with a standard warranty.
