    Power button clicks as if turning on and off but there is no juice. It was manufactured in 1994. Everything looks good the boards are not burnt all capacitors look good. We just pulled it apart and put it back together. Lamps seem to be alright also. Could it be a weak transformer?

Yes, tv should be Power On to find any video source and if tv is Off for some reason, it is not possible to switch any source.
How old is your tv and does it show any display on its screen or Menu pop up when you press menu button on remote?

    The power button clicks as if its coming on and off. But there is no juice. No picture sound nothing at all. Pulled tv apart to look at everything it all looks ok. The boards are not burnt the capacitors are not shrunk. The bulbs look fine. Could it possibly be a weak transformer? And as far as remote goes do not know where it is at the moment. Just want to get the tv to come on. The tv is about 16 years old.

    yes, most likely H-out transistor or flyback transformer could be faulty, high voltage block could get shorted out as tv is 16 years old and things gone bad after such long run.
    Ask local tv repair guy for visual check to rectify problem.

I have a 1 horsepower variable speed blower motor for a Ruud furnace with plug-in power source and plug-in low voltage signal input plugs. I can't find the capacitor and want to know if I can direct-wire...


No you cant. You have a module motor so there is no capacitor. If the motor is new it may not be programmed. If it is a old motor replace it.

Lost original power source. tried to use 12 v input + polarity and got a picture but pic flickers. is it the monitor failing or power source not right?


Power source probably incorrect, Sounds like it too little and cant keep the screen lit. There should be a label on the back that will tell you the input Amps and Voltage or look at the connection and see if it has the voltage inscribed somewhere on it. Best of luck.

Caller ID Screen not working


Sorry it took so long to reply to your problem.You must try to reset the Clock/Radio's microprocessor. To do this you must disconnect the Clock/Radio from the A/C power source and remove the internal battery. Let the Clock/Radio set without any power source for about 3 hours. This should completely drain all the power from the microprocessor. After this is done, reinsert the internal battery and plug the Clock/Radio into the A/C power source. The Clock/Radio's functions should return to normal. If they do not return to normal. Unplug the Clock/Radio from the A/C power source and remove the internal battery. Replace the internal Battery (CR2430). Let the Clock/Radio again drain all the power from the microprocessor. Insert the new battery and Plug the Clock/Radio into the A/C power source. The Clock/Radio's functions should return to normal.If you should still be having problem with the functions of the Clock/Radio, you will need to call Emerson Customer Support. The telephone number for Emerson Customer Support is 1-800-909-1240. Call them between the hours of 8am-4:30pm CT. Give them the make and model number of the Clock/Radio and ask them for assistance with your problem. I hope this information help you with your problem. Thank you for using FixYa and have a nice day!
