Please note: some Sony models from this generation (Sony KDL-46Z4100 for sure) come in different internals 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.

Failure symptoms

Like most other boards the BT2 T-CON in  SONY KDL-46Z4100 can fail in many different ways and cause different symptoms of the TV.

The most common issue addressed by this repair is the TV refusing to start with either 2, 13 or 14 blinks error code at the front;  good check for whether the T-CON is at fault is to see if the unit would start with backlight , even if for a short while. when the T-CON is disconnected from the main board.

Another popular failure is the TV starting (with backlight) with nothing on the screen, for a short while, and then shutting down with the 13 or 14 blinks error code.

Starting up with corrupt image, green lines etc. may also be treatable, though with less success (statistically).

Typical turnaround time is 2-3 business days.

This is the time it takes for a package that was received to move up the queue and get opened.

Once we open the package we usually have about 1 hour to get the case resolved or we will likely end up losing money on it.

Sometimes, depending on situation, we may leave opened box and make another try on the next day.

Note that it is not guaranteed that the queue will take exactly 2 or 3 days to process. Sometimes - especially after long holodays - it can be larger and take longer.

We do our best, but we have no efficient means of managing the work load on demand.


The board(s) we receive must be physically intact and must have not been tampered with or serviced before.

The advertised flat rate for repair service is only valid when the above conditions are met.

Exceptions are possible and often applied for minor repair attempts, but we reserve the sole right to judge if and when we would consider a repair minor.

If we receive board(s) that fails the above conditions we will contact the sender and usually offer two options: 1) returning the board(s) for the sole cost of the return shipping; or 2) continuing the repair service at a higher cost in case of success.

It is also possible, depending on the condition of the board, to eliminate the second possibility and just flat our reject having to service the board.

Subject to situation and availability we may also recommend replacement of the board, again at the higher than advertised price for repair.

In all cases you will have the option to receive your own board(s) back for the sole cost of the return shipping.
