Hello: Your problem is in the power supply, there are two 2200UF 10volt capacitors in the upper right corner of the power supply that are leaky. The Capacitors supply power to the System Control board and other various parts to the television. You can replaced these your self if you have a mind to and is some what electricaly inclined. These should be replaced with 16v caps instead. If you decide to repair it yourself, after taking the back off, the power supply is generally in the middle of the unit, you will have to remove a metal sheilding paned from over it and look in the upper right side of the board the capacitors should be obvious as they are bulgeing on the top they are right next to each other, They carry 5v to video brd and other parts...

Samsung LN-T4661F will not display PC; displays 'mode not supported'. Using a VGA cable to connect laptop to tv


Look in the manual for the TV and determine which platform is supported. VGA, XVGA, SVGA etc. Set your computer output to the proper mode and the unit should work. Let me know how you make out.
