SOURCE: Power On + red LED turns on + but final relay (click) don't come so no sound

Your audio output transistors are shorted and your unit is staying in "protect " mode to protect your speakers from 40 to 60 volts that is being sent at them from the shorted outputs. If you can use a meter you won't need the schematic MOST likely because the outputs are USUALLY the only parts that short out. The output transistors( or chip ) are mounted to the large, finned heatsink. The #'s on the transistors start with "2SA-" and "2SC-" followed by numbers. There are two output transistors per channel. If your unit uses an IC for audio output then the # on the IC will be "STK-" followed by numbers. These parts are available from tritronicsinc.com. Good Luck!

SOURCE: axu heat and outside blower fan run all the time

I can tell you exaclty whats wrong . and it sounds like multipart problems. you have an old RUUD heat pump and its reversing vavle is stuck. without that valve opening it will contantly try to run in refrigerant mode to make heat. and here its 26 degrees, het pumps are only made to be effiient in over 34 degrees and that why your electric heaters in the blower section in an in a closit of unit
continously running up you eectric bill big time. cuses for the reversing valve to stick are sitting along time when it was low on refrigernt. or ust plain shut depending on its age. that cicking is the relay trying to open or close the reversing valve swict to make pressure again. any local guy an fix that one. theyre are kits called hard start kits that they hook up to them that shoot an extra zap of jiuse in it to try to free it up if its not totally lockd up being though that you still hear the relays pulling in and out thats good you may have just caught it in time.

now here is a quick test and possible cure but only if you what your doing turn both units off take off the top cover of the old rudd and get a small hammer not a sledgehammer and rap and tap all around the reversing valve. it will be a cylindrical tube black usually have sets of copper or brass tubings going in the 2 sides of this so dont hit itthat hard it gets dents it and is ruined. look for oil spots which uually means the refrigerant leaked out , and its seized up for good. they try spinning around the big out door fan door fan some. you may have to rock it back and forth Till it braks lose but dont put super human efort int it,

than put it all bak together making sure you connected wires back up right. go in and have you wife eithe watch it or you do it and switch the breker on and off about 8 times to trying to get the cnnectors switches to stay in and if your brave take a well insulated screw driver and hold them in for 2-4 miuntes to force it to work. if that doesnt do it call your local repairman and tell him you need a hard startkit only much safer, the cost about 40$ but you labor will be high if he is sent alone so may you can help im out and lessen your bill if the valve cant be made to work again. you may want start looking for prices with that model and serial number and d shut that electric heater off some one to replace it . I hope I helped you out some no charge ( I dont have my Pay Pal acct. set up yet ) good luck tom.

SOURCE: When the unit is turned on the unit makes a

Your unit is going into the protect mode. If this still happen after you unplug "all" the speakers, your output amp/trans are shorted/grounded... send it to Sony their price to repair is with in reason. Don't want to spend that, get a new unit. "And" check your speakers that they are the right ohms speaker and not shorted out and/or have bad wires feeding them.

Many of the MTH Protosounds 1 and 2 and Trainmaster will not work with the Lionel CW-80 electronic power source. The output waveform is so non-like sinusoidal. The electronic sound systems will not usually respond to this waveform and when they do, the sound will be garbled. Use another power source.

Sounds like your power transformer is going bad inside the unit. Time for a repair man to visit you. Be warned, it's not going to be cheap. If you have a battery backup on your computer, try plugging the TV into that and see if it continues to shut down. If so, it's definately time for a repair man.
