Samsung LN-T4665F 46" HDTV Screen is BLACK - NO PICTURE

I bought a Samsung LN-T4665F 46" LCD HDTV in June, 2007 from Best Buy. Within 9 months I started having problems with it. The screen would remain black when I turned it on. The blue light on the bottom of the set would come on, so I know it was getting power.

After reviewing several forums on the internet for similar problems, I found one temporary solution was to turn the set on and off about a dozen or so times and the picture "might" stay on..........Well, I tried this. Sometimes it worked and sometimes it didn't.

Fortunately, I purchased the 4-year warranty for $349.99 when I bought the TV in 2007. (I don't normally do this. However, the cost of the TV then was over $2,800, before taxes.) So, I called Best Buy to request service. It was like pulling teeth!

However, to make a long story short, it's taken almost a year and no less than three (3) service calls to my home by a service technician. His last visit was on 8/1/2009, when he finally replaced the LCD panel/screen, the main power supply board, and the main circuit board in the TV. The cost of the labor and parts was well over $3,000. No kidding! The technician sent me an email showing the cost breakdown. Fortunately it didn't cost me a dime because of the warranty. The TV worked OK for several weeks, but then the same old symptoms started occurring again a couple of weeks ago.

I then called Best Buy Service (The Geek Squad) on 9/22/2009 again and demanded a new HDTV. They told me they would seek management approval for me to acquire a new TV and would get a confirmation number to me within 3-5 business days. I'm supposed to be able to take this issue back to the Best Buy store, give them the confirmation number and get a new, comparable TV.

I'm now waiting for that confirmation number from The Geek Squad. If I don't hear from them by mid next week, I'll call them back..........

It's been a long two (2) frustrating years with this Samsung TV, Best Buy, and their Geek Squad!

I'll follow up with more info in the days ahead...............

Samsung LN-T4665F when powered on picture is ok for 4 secs or less then screen goes black. Sound ok. I think the video is there just no back-light. Following some online advice I replaced the power-supply...

You more likely to need to backlight inverter boards, thpower supply should have 24vdc for the backlight inverter board, the 24vdc power supply get the trun on command from the controller board, that is what should have been checked first. So look for 24v or measure it directly on the inverter board connector pin. The invereter board also has a couple surface mounted fusesYou can get the inverter board here but make sure to match the number:

Need a remote fix for no picture but still have sound for samsung

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

LN-T4665F 46 in. LCD- Black Line across screen

The set is under a year old and is under warranty. The LVDS cable inside these sets have a history of coming loose. The problem could be the panel. Either way, the set is the problem and needs to be looked at. This set is worked on in the home and does not need to be taken to a shop, so, you can still use it. Contact Samsung at: 1-800-SAMSUNG Hope this helps.
