Question about Samsung Televison & Video

3 Answers

Samsung LCDTB T4665F. Comes on with no picture but with sound only 90% of the time you turn on the set. The other 10% of the time it comes on with good video and sound and will stay on as long as it is not turned off. When the unit does not have picture and sound only and you play a DVD, there is also sound but no picture. The same is true with the VHS and PC connections. Nothing you do will get the picture on. If you turn the set on and off a number of times, occassionally you will get a very momentary picture. At last you will turn it on about 1 out of 10 times and all works well. Any help you can give would be very much appreciated. Thanks, Tom

Perhaps the capacitors are bad on this or maybe something with the power supply is causing this. Your board may also be going. Unplug the tv and take off the back panel and take a look inside. See if the capacitors (cylinder looking things) are looking like the top is about to explode which would mean they are going bad. Also see if you smell anything burnt or see a loose connection anywhere. You should also test the connections from the board to the screen but if you don't feel comfortable doing this, then don't.

Please let me know if you have any questions or concerns with this and I would be glad to help you out.

    Also, if this set is still under warranty, then don't even attempt to open it, check into the warranty and see what they will do for you.



    good luck

There are a number of things in these sets that can cause this type of fault. It is very common that the power supply may be failing, or the backplane power supply and or the backplane lamps. I have also seen faults in the video processor areas that caused a black screen.

The service rep will do board swaps to find the defective board(s). He will leave in the new boards to make the repair. These sets are not supported to service at the component level.

If the case where the backplane lamps are defective, in some screens these are not replaceable. This means a new screen unit to fix it, and that would be too expensive.

Well..these all have one thing in common. The video board is on it's terminal velocity curve..which means, that either you or someone else, has some work to do...

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
