You have a bad Power supply. Have a trained Samsung tech replace the Power Supply.

    I fixed it. It had a bad LCD inverter. I took the back off the LCD TV and there where four LCD power inverters. I put my ear up to the buzzing noise that was coming from the right side of the TV (Looking at it from the back) and it was coming from the inverter that was located at the top right. I replaced that inverter and the problem was solved. I found the two right side inverters on eBay for $50.00.

    Also if you open up the TVs power supply and check out the capasitors and they are popped, puckered or have brown stuff coming out of them then you are going to have to replace your power supply. I checked mine and they were fine. I fix laptops and heard buzzing from bad inverters before but every post I read online said bad power supply to most problems like I was having. Then I saw this one post and the guy said it sounded like a bad inverter and he was right.

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

LN-T5265F Samsung takes couple min to power on (clicking while).


Take the back off and look at the power supply. Top right on the board, see if a capacitor has gone bad. I've seen up to 4 caps go bad in the little area. replace with a higher voltage and you'll be good to go.

Picture goes blank after a few seconds of turning on power


check if the back lamps are still on when you lose image, all you have to do is get close to the screen and make is totally black and if is not that means you have a back light working, but if the back light is gone you may have a defective panel.

talked to samsung TA about the same problem I had and the recommend to replace the power supply first to confirm a defective panel because a panel is quite expensive
