Samsung LCD 40 inch LNT4061

I bought Samsung LCD 40 inch LNT4061FX/XAA about 1 year ago. So I don't have any warrently left. It was working fine until one day two white lines came up and TV stopped working. I disconnected everything and reconnect all the plugs but nothing on screen or any sound. After few seconds it try to turn it off itself and after 10 seconds or so it try to restart itself and it keep trying to start. Only thing I see is blanking LCD light. Any idea how I can fix this. Any help would be appreciated.

    I have the same problem PLUS more... My TV had the on off issues that grew into dots on the screen and then just a black screen and now all I have are vertical lines all across the screen. My TV is only 1yr7mo and guess what, no warrenty. I did get a nice message: I am sorry that you are having difficulties with your television. That is frustrating when you can?t use your product.

    I was able to find a purchase of a 40? Samsung TV purchased on 8/20/07. This television has a 1 year manufacturer?s warranty, so it would be expired at this time.

    If you do need repairs, you can still get them, but there is not a warranty or service plan we could charge it to. You would be required to pay for any repair services. I do apologize.

    I do hope that you have a good day. If you do want to get repairs, please call 888-237-8289, select option 1 for English, then option 3 and ask our operator for the TV repair department.

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 CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.

I have a samsung LN-T4061f. It will begin flashing like a strobe light after a short time then the scren goes blank. I still have sound. I have done the turning it off using a power strip and that worked...

This set may have a separate back light inverter or it may be incorporated into the power supply. Here is the parts list:
If you note, the power supply is out of stock. That is an indication that it is a common failure item.

My my samsung LNT4061FX/XAA turn on but no pictures only sound whats wrong with it

If you shine a flashlight onto the screen, can you see a very faint picture. If yes, then your lcd panel is not lighting up. Replace the inverters or the panel.

first I would check the power supply for faulty caps, replace if neccessary.

I have a Samsung LNT4061FX/XAA Serial no. AHBA3CSPA03617J. The TV will not turn on. It just continues to Click and the Red light in the front goes on and off. Is there a part available to fix this problem?

Regarding the problem with LNT406FX/XAA models not powering up - I contacted Samsung @ 1-800Samsung and they issued a repair tag and put me in touch with a repair company that came out the next day and replaced the capacitors on the power supply. Apparently Samsung got a batch of bad capacitors from a supplier and they know which TVs by the serial numbers. My TV was 28 months old and there was no charge. TV works fine now. Good for Samsung for acknowledging they had bad parts for and getting the tv fixed at no charge.
