Coppell TV Repair LLC offers you a repair kit for sustain board TNPA5335AJ used in Panasonic TC-P50GT30 and possibly others.
The repair kit contains parts for at least TWO different failures we have seen on that board. We recommend replacing all components at the same time anyway to avoid the risk of repeat failure if some component tests out fine, but fails in real life conditons; we ourselves replace all components when servicing the board.
In our experience you do NOT need to replace the screws for the board, but you DO need to make sure you reflow the solder on the back and top of the board where screws go as it may have gotten damaged and corrupt over time.
If a DIY service for the board looks too difficult you are welcome to send it to us for service and testing - see repair service listing below.
Lastly, bear in mind that if your SC board is bad then so can be the SU and SD boards; we offer test and repair service for those too.
Brand new replacements for (Q401, Q402, Q403, Q621, Q622, Q623), (Q421,Q422,Q423), Q600, Q660 and Q661.
More components may be added over time if experience reveals necessity of including them.
If you believe you have a component failed which is not on this list feel free to contact us. Note diodes and other parts connected in parallel to above listed transistors will measure shorted as long as the transistors are still on the board!
Medium. We recommend using hot air gun for desoldering of the old components and either the same and/or at least 50 watt soldering iron for soldering replacements in. No soldering aids or additional instructions are included in the kit.
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 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.
What this means is that if you choose any of the above services as your delivery method you agree to hold us free of claims against loss of value should your package gets damaged or lost in the carrier system as long as the tracking information by the carrier shows the package was accepted by them and processed into their system.
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.
