IF it is making a clicking noise it is the SUB PSU , the one that powers the embedded PC, there are 2 CAPACITORS on the PCB that will be domed at the top a 1000uf and 1500uf, they are on the secondary side , this is a common problem with this and the 460PXN (same psu) replace caps with higher voltage rating is my advice,!!! I did everything OK!!

Samsumg 42pspf301501a no power main input ok


Could be an internal fuse that has blown in the power supply, if that's ok, it could be the switched mode transistor that has failed.

Also check for dry solder joints that could be causing an intermittent connection

I have Att Uverse and a Samsung LCD. We have


If your using the IR remote, the actual colors of the tv are what is causing your problem. What I have found to solve this is go to your local ATT corp. store and order the RF remote this will solve your problem. The techs don't carry these on their truck.

Att uverse remote won't work with other devices


Yes you have to use the recommended Uverse codes, and follow the directions to enter the code. Hold the tv button down, on the Uverse remote, then with it stil held down add the OK button, let go of both, then you will see the lights at the top of Uverse remote light up, it is then ready to accept the code, it will be a four digit code, Go to helpme@att.net, and look under TV, then programming the remote is there. Put remote Code in the att search box if you can't find it.
