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!!

Vr357 no power

If you take the top off of the unit there should be a glass fuse right behind the power chord. If you have a multimeter you can check and see if the fuse is ok by setting the meter on 120 ground the black wire to the chassis and put the red probe on the fuse out side to check for power. If the fuse is bad you can replace it, but you may have to unsolder it.

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.

Generac NP 50G wont crank

Measure voltage drop across the far ends of the fuse wiring (should measure zero), as one of the wires or it's connection to either end of the fuse may be open. Check the battery negative grounding connection at the frame. If all ok, you may need to find a wiring diagram for the machine. Does this unit have a low-oil-level switch which will kill the engine if set?

Microwave is plugged in, but getting no power, circuit ok, cannot find a fuse on the microwave.

Normally if no power is indicated, it is due to a blown fuse but if fuse has blown be careful, it because there is something wrong. Mostly its due to a problem in the power circuit.Can either be the magnatron or the diode capacitor combination.Normally the capacitor goes faulty causing the HV diode to blow. Replace the two components(diode and cap.). If it happens again replace the magnatron. Microwave truely dangerous and needs proffesional att. email me if you want to go ahead yourself

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 [email protected], and look under TV, then programming the remote is there. Put remote Code in the att search box if you can't find it.
