Coppell TV Repair LLC is offering a repair kit for a failure we've seen develop in Samsung power supply board BN44-00268A / I55F2_9HS shown on the picture .
The board is used in a number of 55'' LCD TVs such as LN55B650T1FXZA, LN55B640R3FUZA in USA and others in Europe and Russia.
Kit SKU: CTVRL-NO-PB-0144
Failure symptoms
The typical manifestation of a problem addressed by this kit is the loss of backlight after the TV powers on; the screen would just remain dark. In some rare cases it can flicker intermittently before ultimately setling on black.
Manually illuminating the LCD panel with a strong source of light such as a flashligh would reveal weak picture.
Please pay attention that many different failures may cause this outside symptom; for example a defective CCFL lamp would do the same, a defective transformer would do the same, even a corroded/bad contact in a connetor could do the same; we present this repair kit based on first hand experience with particular actual failure we've seen more than once and which is logical to affect more boards.
Kit contents
Brand new replacement component(s) for the parts we have seen cause the failure.
Difficulty level
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.
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.

- 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.
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.
