Question about Sony CFD-S300 Radio/Cassette/CD Boombox

1 Answer

No power to unit. All functions dead.

I have used this unit very little and when I turned it on the other day nothing happened. I checked my 120 Volt source and the power cord and I had power to unit. I dismanteled covers to see if there was a fuse but could not find any. The unit had not been used for approx. 4 months prior to turning it on and it had always functioned properly before.
The product is out of warranty and Sony has a program of replacement with a refurbished unit which actually cost more then I can by a new unit for.
I would appreciate any help in troubleshooting the problem.

    Thank-you Jee for your help. I will check it out this weekend. I forgot to mention that it does'nt work on batteries either. Do you think it could still be the power transformer.

My oven is dead - no display, no nothing. Circuit breakers are fine. Turned them off overnight, still nothing on oven this morning. This happened about a year ago but oven came on again ten minutes...


What you need to check is for power at the clock.TURN OFF BREAKER gain access to clock and use volt meter. One the clock will be wires maked L1 & N on those 2 wires when breaker is turned back on their should be 120 vac. IF 120 vac at those 2 wires,replace the clock, if not 120 vac into clock check for burnt/broken wires

You say the unit is 220 volt, but the plug you installed has a white wire which is normally on a 120 volt outlet. A 220 volt outlet would have 2 black wires and ground. If you do have 220 there, and the reset does no good, I've seen those resets(they are basically built in GFI) blow out and had to bypass/put different chord on. there are fuses on the control board but I would check that last

Our son bought a ARC-125 Whyniter Portable Air Conditioner the summer of 2009 - he accidentally plugged it into a 220V outlet and evidentally fried the components. I would imagine it's not fixable but...


Hi Karen, and yes more then likely a lot of the controls were cooked. It doesn't take long with that high of voltage to take out motors, burn the insulation off of wiring and so on. Depending on how long it was plugged in and how long that much voltage had run through it, try plugging it into a 120 volt receptacle and see what happens. I would do this before any thing else. I have seen this happen on other units and just melt the 120 volt power cord. So, plug it in to see what happens, and if it seems to run good, you may have turned it off in time. If nothing happens, and this unit cost you a lot off $$$, it may not hurt to take it in to a appliance repair shop and get an estimate. If you smelled a lot of electrical burning, I would look at where the power cord comes and ties in, that may be as far as it got and check it if you have someone that is able to do this. But, my guess it is probably dead. I am sorry this happened to you. Please don't forget to rate my post as I know you will be kind.

all atx powersupplies are generic-it dous not really matter what computer it comes from unless its a high end pc requiring loads of power-if your machine is intel you may need a supply with an extra twelve volt lead(two yellow and two black leads in a little block)-but for that pc i would just harvest a powerpack out of a dead machine

Mr. Heater Natural Gas Garage Heater - 45,000 BTU. Power 120 volt and 24 volt good. Thermostat calling for heat, but nothing happening??


Check for a fuse either in-line or on the circuit board. There should be 24 volts going to the thermostat. If not, you have either a bad transformer or a bad thermostat wire. Jump out the terminals that the thermostat wires are connected to. This should force the unit to fire. If not, bad circuit board.

Might your switch be non-functioning? Can you check that independently?

Otherwise, sounds to me like you did eveything.

Audiovox AVT2540 won't turn on


Hi,

The only possible check that could be done without removing/opening the Audiovox TV would be to check for the presence/absence of supply power/voltage depending on how the TV is powered (12VDC or 120 VAC). Normally, there would be an fuse and/or circuit breakers.for the RV's entertainment system including the TV.
The 120-volt circuit breakers and 12-volt fuses are located in the same compartment. These devices interrupt the power if the circuit is overloaded.The 120-volt circuit breakers include a 30 amp main breaker and several smaller breakers for individual circuits. If a circuit breaker is tripped, look for an overload on the circuit, then reset it by turning the breaker OFF and then turning it ON. Do not try to reset a breaker the second time without locating the overload problem. The 12-volt fuses protect individual circuits. If the circuit is overloaded, it will blow the fuse and the fuse must be replaced. Check the circuit for an overload and replace the fuse with the same type or amperage rating.

If the above checks out, then problem is internal to the unit and would require removal from its current position.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Are you certain the polarity of the connections to the TV are correct? If you connected them in reverse you may have damaged the TV. If there's a fuse in line check that too. BMW
