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. The board on left, you will see the cap tops are swollen.

Thanks for using FIXYA, BIG IRISH.

Will not power on..have to unplug wait till red power light goes off then plug back in ..then will power on fine


Power cycle your TV by unplugging it and leaving it for a few minutes. Plug it back in and turn it on. Restore settings back to factory defaults. If everything else fails, then I would recommend pursuing repairs.

My Samsung model HLR4667WX/XXA is making the same buzzing noise I've read about by googling the model + buzzing noise. I need someone in Phoenix that can replace the color wheel or so it seems. Please...


It is easy; just look for a video on you tube and with a screwdriver and some care you can fix replace the color wheel yourself.
I replaced mine in fifteen minutes. Note, I had to replace my ballast prior to this so I had a little experience.
Good luck.

46" LCD Samsung TV Model# LN-S4692D I have no picture


The back light inverter board may have gone out or it is not getting the 24vdc from the power supply module. Start checking for voltage feeding the inverter board.

Samsung lnt4042hx/xaa 40in lcd tv wont turn on


I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!
