Coppell TV Repair LLC is offering a repair kit for a common failure we have seen in LG power supply board EAY58316301 / PSPU-J806A.

The power supply board is used in LG 50PQ20-UA, LG 50PQ30-UA, Sanyo DP50749 P50749-01 and possibly others.

Note this repair kit requires soldering skills and equipment (not provided).



External failure symptom of the failure that this repair kit addresses is the TV clicking once upon attempt to turn it on and them almost immediately clicking right back off and never actually coming up.

The same failure symptom can be shown for a numeber of other reasons, though, and is not reliable indication you need this kit.

If you can check fuse F801 on the board and find it open that is a definite indication that you need this repair kit, just as if you find either of the two power transistors Q801 and Q802 shorted between any two of their legs.


At time of creating this repair kit the contents were as follows: F801, Q801, Q802, IC801.


Easy to medium. Generic soldering equipment should allow doing the job.

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.

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 the following delivery services are NOT insured per USPS policy:

    • Domestic: USPS First Class;
    • International: First-Class Package International™, Priority Mail International® Flat Rate Envelopes and Priority Mail International® Small Flat Rate Boxes; services to some countries may also not be covered, for details read the USPS article on the subject.

    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.
