If your OLEVIA 537-B11 LCD TV does not want to power on or powers on only to power right back off you may need this power supply repair kit

Coppell TV Repair LLC offers you a set of replacement electrolytic capcitors commonly failing on power supply board of OLEVIA 537-B11.

As with many other power supply boards those are the output filter capacitors for the main board and inverter boards.

When going bad, electrolytic capacitors often tend to bulge their tops or bottoms - and are an easy catch even with a naked eye.

On the other hand, they do not necessarily go bad at once and it is possible for them to be bulging and still be operational for quite some time - depends on the particular capacitor and circuit it is in.

Which is to say that bulging capacitors, while a clear indication of a need for change, are not necessarily the source of malfunctioning of a TV.

For a troubleshooting experience on this particular power board due to bulged capacitors please see


The kit comes in two versions - standard and plus.

The standard version contains the capacitors that we have seen going bad as per the above article and a few more that MAY go bad based on past experience - pretty much the major electrolytic filter caps on the board except the mains.

Specifically. the capacitors included are: C26,C27,C42,C43,C62,C65,C66.

The plus version also includes the mains filter capacitor C10.

We strongly encourage you to look at the capacitors on your board before ordering.

If a capacitor on your board needs to be replaced and it's not in either of our offerings please do not hesitate to contact us prior to ordering!

    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.
