EAY58316301 PSPU-J806A power supply repair kit for clicking on and off, failing to start LG 50PQ20-UA, LG 50PQ30-UA, Sanyo DP50749 P50749-01 and others

A DIY repair kit for a common failure in LG power supply board EAY58316301 / PSPU-J806A causing it to click right back off upon trying to power on.

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.


Normally ships within 1 business day. Unexpected delays may occur, but if we can't ship within 3 business days we will contact you or/and cancel the order.

We try to ship every business day M-F and, for USPS shipments, Saturday as well.

Items under 14 oz are normally shipped with USPS First Class mail unless other option was available and chosen during checkout.

Packages of 1 lb. and above are shipped USPS Priority, FedEx Ground/Home, subject to our decision.

ATTENTION INTERNATIONAL CUSTOMERS: If your order is accepted by our store and your address is outside United States you may not be able to track package delivery progress once it leaves the country. The United States Postal Service (USPS) does not provide tracking information to some countries unless the shipment is the most expensive Express type, which is usually too expensive to justify using. You can accept that condition and strip Coppell TV Repair LLC of responsibility to the delivery status of your package provided we show it was shipped and processed by a courier in a timely manner. Or you can contact us prior to ordering and inquiry for delivery confirmation shipping method, which, again, usually costs an arm and a leg compared to the simple USPS First Class shipping.


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.
