Intermitant snow means your tv is not getting signal continuously. Please check the input signal connection and source to your tv.

SOURCE: Have Model Code LNT4061FX/XAA

Three capacitors on the motherboard are bad. They cost about 2 dollars each. If you are handy, you can take the tv apart and replace them. It took me about 30 minutes. Unplug the tv. Lay it on a large table so the stand can hang off without tilting the tv with the back of the tv facing up. take all the Phillips screws off the back cover. Take the back cover off. There is a grey cover about the size of 8x11 inches on the left middle area held on by about 6 to 8 phillips screws. Take it off. Unplug the motherboard, there are about 5 different plugs. Unscrew it and take it out. There are 3 somewhat swelled 1000mf 10v capacitors in the upper area of the motherboard. Replace them with 1000mf 16v capacitors, soldering required. Make sure you install them with the ground in the proper hole. Put it all back together and you are fixed for less than ten dollars. Samsung should be doing this for free. It really makes me mad that they can put out such an expensive product and not accept responsibility for a potential fire hazard. I will make sure anyone who wants my opinion about an electrical product knows how bad samsung is. Good luck.

What ever you get make sure they are 105c rating, AND LOW ESR which is must for switching power supply, if they do not know what ESR is, do not even buy the parts from them, also high ripple current rating and life rating in hour at 105c.
I use PANASONIC FM/FC series from DIGIKEY.

SOURCE: My my samsung LNT4061FX/XAA turn on but no

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.

What parts do I need to fix a Samsung LNT4061FX/XAA with a picture issue.


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

If you have not tried it: unplug the set and if using a cable or sat box unplug that as well---wait for a while and plug both back to see if a reboot of either cures the problem or not.

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.

Intermitting blue screen whilst watching my dvd


I'll need more information, but it sounds like an encoded (for copy protection) dvd being played through another device before going to the TV. That intermittent blue screen is usually that. How are you hooking up to your TV?
