All other input works fine e.g. dvd, TV went pink screen.


If other inputs show no problems and you are not using a cable box or satellite receiver, etc. just off air antenna, something on the main board is failing. please double check other inputs again.

Pink screen on sumsung LCD


Likely to be a bad main board that processes all signal and controls the display panel for tuner and all inputs---other possible boards not likely as they do not know when a DVD etc is being played or not.

Not out of the realm of being possible is a bad connection or loose plug to or from the main board---especially look for any that are secured or held down with tape where they plug into that board.

Self- reboots at start-up, then shows picture but with pink dots.


Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM811, CM812, CM817 & CS806; 1000ufd 25volts. It is the board to the left and you notice that the four cap tops are swollen.
It is easy to replace get a stanard solder pencil and you are in business.

Thanks for using FIXA, BIG IRISH.

Pink and green lines while watching a movie


if this is only happening on your dvd player, then change the type of cable used to link the tv with the dvd player, if that does not fix it then try another dvd player to make sure it's not the player itself

No blue colors projected on screen


Only a few causes for this problem. "Splotches" are usually caused by dust in the light engine which can sometimes be blown out using compressed air. Pink picture is caused by either data or burnt lcd card. Procedure for data is: put tv to ch. 3 and turn power off. simultaneously press input and power on set for three seconds to access service menu. Be very careful not to change settings other than what needs changed. These adjustments are changed using directional arrows. Navigate to "memory init" then hold (r) arrow button for 5 seconds. You will know if it worked. Then exit and/or turn set off. Please let me know if this is successful as I have additional info you may need. Good luck, Russmann.
