Coppell TV Repair offers you a repair kit for Samsung buffer board LJ41-05121A / LJ92-01491A as shown on the picture.
There are several very important things you need to know about this kit, so please read this listing carefully:
Bear in mind that when either of those buffers fail it usually kills the YSUS board.
This kit contains the four ICs that are used to dispatch the sustain impulses sent by the YSUS to the individual display lines.
You are not getting the board on the picture, only the 4 ICs below it!
Replacing an IC like one of these is a fairly delicate procedure! Do it at your own risk!
We recommend using new buffers whenever possible and only relying on IC replacement when you have no other choice and you have the experience.
Although most commonly only one IC fails on the board , for reasons disscussed at our blog we strongly recommend that all 4 ICs get replaced at the same time.
For the same reason we strongly recommend that you replace or service both buffers at the same time.
Otherwise you'd end up having the same problem.
We have definitely done ourselves what we advertise here.
Alas, we can't describe the techniques we use at our own repair facility - first because we do not want to give know-how to potential competitors and second because it is a delicate task that usually takes investment of time and money before it starts producing return...meaning the first few attempts are usually unsuccessful.
We do not take responsibility for your failure or success when using this kit. All sales are final, no return for any reason whatsoever!
If you have any questions please do not hesitate to ask after reading the listing and especially BEFORE soldering the ICs!
WORKING CONDITION AND WARRANTY
For our own sake, we are very careful to test a few ICs from every new shipment we receive before we put them on the shelf with the rest. And by testing we mean fixing a buffer and letting it run for an hour or two.
Unfortunately, we are not aware of a quick and easy way to tell if an idividual IC is good or not. It means that the IC that you will receive will not be tested by us.
If you are aware of a way to test an IC for you please let us know!
Alas, due to the high sensitivity of the ICs and the inability to know how do you handle them we simply have no way of offerring warranty.
But we WILL NOT TAKE MALFUNCTIONING ICs BACK!
PLEASE DO NOT BUY FROM US IF YOU DO NOT LIKE OUR TERMS AND CONDITIONS!
