Coppell TV Repair LLC offers a REPAIR SERVICE for T-CON board  A1557397B / A1556899B / 1-857-253-11 shown on the picture and used in a number 46'' LCD TVs including, but not limited to Sony KDL-46V5100 , Sony KDL-46XBR6 , Sony KDL-46VL160 and Sony KDL-46Z4100.

REPAIR SERVICE means you have to send us your board, which we will test, service (if necessary) and return back to you.

Please note: some of the above models (Sony KDL-46Z4100 for sure) come in different versions depending on the LCD panel used; if you came to this listing while searching by TV model number DO NOT assume that your TV has this board inside as it may have a very different (and not compatible) one! Open up the TV and use the numbers printed on the board's labels when searching for repair services.

How does it work

Shortly after placing an order you will receive an email with shipping instructions telling you how to mark, package and send your board to us.

The cost of shipping the board to us is not included in this listing and it is customer's responsibility to deliver the board as per our shipping instructions.

Please do not call to ask us if we've received the board. Instead, follow your tracking number and when it says the board was delivered then it 99.99% certainty was.

It takes 2 to 5 business days for a package that was delivered to us to move from the back to the front of the queue and be processed. The time can be longer after long holidays, weather delays etc.

Upon opening your package we first evaluate the board's physical condition for meeting our requirements (see below).

Then we put the board in a TV and verify that it is malfunctioning.

If we determine it functional we get back to you. If no repair service is performed and the board is to be returned we retain a minimum diagnostic fee in amount of $20 plus eBay/PayPal sales fees plus the return shipping costs and issue refund for the rest.

If the board is nonfunctional we proceed to repairing it.

Most of the time we are ready - successful or not - within 1 hour of opening the package. In some rare cases we leave the board for another try on the next day.

If we are not successful with the repair once we have undertaken it we issue you full refund and cancel the transaction. We do not make money in this case, however we still invoice you for the return shipping of the malfunctioning board.

If board is repaired and tested properly we directly send it back and do not communicate the success. You are notified of the return by an eBay package shipment notification.

Board failure symptoms

There are several different failure symptoms manifested by a failing or failed T-CON board and unfortunately most of them can easily be confused with other failures.

The most common ones we have seen develop for this particular board are:

• TV failing to start with 14, 13 or, in some cases, 2 blinks at the front LED indicator
  
• "Whitening" of a portion of the display - a white blob slowly growing and taking over normal image - that one may not always be repairable
  
• Display may show normal image for a while and then start deteriorating after warming up with any or a combination of the listed symptoms
• Lack of display (but presence of back light ruling out the possibility of bad back light inverters)

The board we receive must be in good physical condition and must not have been tampered with, i.e. no apparent traces of previous repairs should show.

We will reject service to boards that someone has attempted repairing and you will still be charged for the return shipping and the eBay/PayPal fees.

Please do not buy if you do not agree with this condition.

If you have any questions or doubts please ask us prior to buying.

If you have less than 10 positive feedbacks on eBay please contact us PRIOR to placing an order! Failure to do so will indicate you have probably never read this text and you may as well be expecting that you are buying BOARDS, not SERVICE. As such, we reserve the right to cancel orders from buyers with less than 10 positive feedbacks.
