Samsung LN-S4051D slow to turn on.


You are likely to have a module bad....part number BN94-00864A and if you take it out (unpluggs) you should inspect it for capacitors that may be domed or pooched up at the top. If so they should be replaced first before getting the module as the capacitors are about $1.00 each. Do a search for Samsung parts online if you need the module and call them toll free

It taske up to 15 minutes for the television to


1. Lay the TV Face down on a padded Table and removed all the screws. The tback just Pops off.
2. There is a protective cover over the circuit board. unscrew and pull off.
3. Unhook all of the wire attachments that connect the board to the rest of the TV and unscrew the 6 screws that hold the board down and pull it out.
4. There may be bulging capacitors on the top right or somewhere on the board. You can take the whole board into a repair shop and they can tell you what replacements to buy. (Upgrad to 35v to prevent future problems)
5. De-solder the backs of the bulging capacitors and clipd the leads.
6. Put the new capacitors in their place (watch for the polarity. bend the leads to the side to hold them tight and solder them down.
7. Replace the board.

****WORKING INSIDE A TV IS DANGEROUS DUE TO HIGH VOLTAGE***IF UNSURE, LEAVE IT TO A PROFESSIONAL.

When I try to turn on my Samsung LN-T4042H LCD HDTV it is now constantly clicking in a continuous loop and will not immediately turn on. It started out small- a few clicks yesterday morning. Today it...


There is a problem with the power supply in your TV. The regulator switch is causing teh clicking sound you hear. In order to fix it, you will need to replace the power supply. This is done by taking off the back cover of the TV, locating the power supply which is usually a yellow board that will have many high voltage capicators on it and replacing it with a new one.
