This listing is for a used buffer board Samsung LJ92-01203A / LJ41-02761A as shown on the picture (revision may vary, but most commonly is A5) and as used in a great number of 42'' plasma TVs utilizing Samsung 42'' plasma display and Y-Main sustain board LJ92-01200A.
The board may be just a pull-out from a liquidated set or may be a serviced one (one or more ICs on it replaced).
It would be definitely tested by Coppell TV Repair in a live functional TV set prior to being slated for sale (and we do mean that, it is not just a marketing statement!).
However, since each such buffer comes from a TV that has been in use for some time (quite possibly long time) the life expectancy of that board is going to be limited.
On top of that, a damaged Y-Main board LJ92-01200A can easily kill newly installed buffers we are in no position to offer what would be considered a standard DOA either: if your Y-Main is bad in a particular (and not uncommon) way then the buffer will be killed the first time you put it to work on that Y-Main.
Because of that
THE BUFFER BOARD IS OFFERRED "AS-IS", WITHOUT ANY KIND OF WARRANTY!
THIS MEANS THE BOARDS CAN NOT BE RETURNED FOR ANY REASON.
You can test the buffers as explained at our blog and that would allow you to detect apparent shortages, which are luckily the most common type of failure they develop. Still, sometimes a board can fail in a way that would result in perfect testing results with a DMM and would allow TV to power up with picture, but there will be defective horizontal lines making it useless.
Note: because of the high risks associated with improper repair and handling of the Y-Main board LJ92-01200A we only offer new buffer boards (the 4 ICs version) as part of a whole package or to customers who send us their Y-Main LJ92-01200A for evaluation and (if needed) repair.
