Ge spacemaker radio model 7-5402 problem

I have this radio, 1 year old at x-mas 08, the power went out the other day now the tuner will not pick up any of the 3 local FM radio stations, or any station at all. I get nothing but static when I set tuner to channels. Auto search comes up empty as well.

I cannot find this product anywhere on your site either to get help that way.

    same proplem, one day everything was fine and the next day no fm stations. about 2 days later i lost all my am as well. i puchased mine for my wife christmas 2007.

    The tuner in my GE Spacemaker went on the fritz also. The antenna is in the power cord which is much like most of the clock radios sold these days and therefore is subject to interferences from other devices which may be installed close by. I was about to take mine apart and check to see if I could install a separate antenna to improve the reception. Before I did that though I decided to try a little experiment by tuning into a station that I know is strong and just leaving the radio on for several hours with the volume turned down. Much to my surprise when I came back the radio was working fine and could tune all local FM stations. Possibly the electronic tuner needs to "warm up" a bit before it will work properly. As a solution I am just going to leave the radio on all the time and turn the volume down low when not using it rather then turn the power button off.

    I have same problem as the others I've read. Static on A.M. and F.M. A while back if I left the radio on all the time and it would work but now I have nothing but static all the time whether I leave it on or turn it off and put it back on,nothing... This radio is only two years old. I would like a solution to this problem.

    I am having a similar problem with my GE 7-5402. Have had it for a number of years no problems. REcently started getting nothing by static. Had been bunching cord so straighten it. If I leave it on for a longtime might get stations back might not. Have there been any updates on this problem before I just go buy another one?

OK, I found out what the problem is.
ON my GE 7-5402 Spacemaker under-cabinet radio, the FM was only static. I've opened it up and there is a component which is failing. When I used a heat gun on the circuit for about 5-10 seconds, it started working and it stopped again when it cooled off. After some time I isolated which component it was that needed the heat in order to work. Here's where to find it:

  1. Remove the top (25 screws of various length)
  2. With the LCD facing you, look to the right of the CD-drive close to the large aluminum cooling fin.
  3. There is a single transistor with markings of: "D2012" and "6:R".

This transistor is the problem and I believe if it is replaced, the FM radio should work. I'm going to try it and see what happens. I think I found the right one online for less than $1.
Hope that helps you guys!

    I think the part number is transistor D2012 and it also seems to be listed as 2sd2012.

  • mevoilarc Mar 18, 2011

    Hi Sweethands,

    Would like to know the result of your transistor replacement.

    Thx

  • David Wiebe Mar 19, 2011

    I've got the part now - I just haven't had time to put it in... I will soon, my wife keeps bugging me to do it

  • David Wiebe Aug 30, 2011

    Well, apparently I'm extremely busy (You really have no idea!). So I finally got to replace the transistor, and it STILL DOESN'T WORK! :(

    Brand new transistor, soldered it in and checked my work. Actually a very nice solder job if I do say so. Anyway, after assembling it again, it still doesn't work. Took it apart AGAIN and found that it still has the same problem. If I isolate the transistor and heat it up with a heat gun, it works for a while until it cools off. Then I can heat it for 1 second and it turns on again. I suspect that heating the transistor must somehow change the signal (Boost it?) to a different part of the radio which then causes it to work. However, it seems that a new transistor does not fix the problem.
    This is major sucking. Now I think after all this effort, I'm just going to throw it out.

A fix that worked for me with the static on the radio. turn on radio to fav stationthen turn on your light under the unit wait about 15 min. the fm station slowlycame in. you have to leave the light on. seems that the light warms up something inside the unit and the reception gets better. soon as i turn the light out i getstatic again on am and fm. did not want to part with the radio cuz i really likethe weather station. worth a try. feb 19/12

@Sweethands

That's great troubleshooting. I have taken it a step further however, and using a can of freeze spray which allows narrowing the problem further, I have found that it is the power amplifier IC under the large heat sink that is the problem (aluminum cooling fin). By carefully cooling off JUST THIS ONE component with the freeze spray I can get the radio to fail again as soon as the spray hits it. Because of the large ground pins on the side of this IC it is very difficult to remove. However, after removing it I found that it is a CD8227GP audio amplifier IC, and can be substituted with an NTE7157 which is available in New Jersy. You should be able to order it from a local electronics parts supplier.

  • David Wiebe Aug 30, 2011

    Well, I can't argue with your results, the freeze spray is a nice way to test... but I have put a thick paper barrier around the transistor that I pointed out and if I heat it, it works and if I use the barrier to keep heat away from it, and instead heat the part you mention, it doesn't go on. For me, that's how it works. However, just because I can make it work by heating up the transistor, doesn't mean that that's the part to replace... I just replaced that transistor and it still has the exact same symptoms as before. If I heat only the new transistor, the FM radio will work again. It's possible that by using freeze spray you cool off the amplifier so much that even under normal conditions it would stop working. The way you describe what you did, doesn't definitively prove anything. So I don't know what to do now. For me the work-bench symptoms are not the same as you, but replacing the transistor didn't solve the problem. Have you replaced the amplifier IC? Did that fix your problem?

  • Mergatroid Aug 30, 2011

    Yes, replacing the IC solved the problem.

    Heating the transistor can change it's AC or DC beta value which could change its bias level. This could compensate for the IC not working properly by making it easier for the IC to bias the transistor or even allow conduction while hot that did not take place while it was cool (or vise versa).

    In any case, I installed the new IC and it solved the problem.

The probleme come from bad antenna from the power cord just add a extention cord and the reception will be fantastic its what i did.

could not get anything from the radio then read about a sony radio on the same probleme and you just have to add a extention cord and it should fix the reception probleme

    Imagine that! Our GE 7-5402 spacemaker radio did the exact same thing. One day the FM radio just stopped working. We put it away for a few months and decided to try using it again, but FM still is not working... it only has static/snow/white noise. I've opened it up and the antenna is actually wrapped around the power cord about 10 times, so I guess that's supposed to pick up the signal from the cord. Well it was working fine one day and not working the next so I see no reason to modify the antenna. Right now I still have AM, and I've looked at the circuit board that has the tuner and it looks fine. I see no obvious points of failure. (No burnt spots or bloated capacitors etc...)

    I believe I remember that if I leave it on for a long time, then the FM comes back, although I think this was taking longer and longer by the time we stopped using it.
    Does anyone with electronics knowledge know what part on a radio tuner circuit is failing if leaving it on to "warm up" makes it work?

    I'd gladly make a little How-to with pictures if someone can tell me what part to replace. It's only a little difficult to get the tuner circuit board into a position where you could replace a component. There's many of us that would love to know what this "weak link" is!!

How do i tune Mazda Demio (2004 model) radio to Southern African frequencies?


fm frequencies are just that fm frequencies ( not japanese, chinese ,english or anything else
it is a range of frequencies in the fm band that local stations broadcast on
so all you have to do is to turn the tuner knob until you get 107 fm
so as you turn the knob you will loose 89 and it will go probably 90.5 , 100.20, 102.7 etc and if there is a station broadcasting that your radio will pick up it will come in and then fade out as you keep moving the knob
you may have to change the mode as there are fm 1 ,fm 2,fm 3 bands to get your fm 107 as it will depend on what megahertz 107 is operating on

DEH-P7900 BT US model. Isthere any way I could change the tuner frequency to european one. Thanks.


The DEH-P7900BT is almost identical to the DEH-P85BT sold in Europe.

This is a US model and will tune most AM/FM stations in the UK/Europe. The FM broadcast band is 87.8 to 108.0 MHz. so it will not pick up any FM stations outside this range. Also, the tuning is in odd increments (such as 96.1, 96.3, 96.5, etc.) so some stations with even frequencies will be slightly distorted, depending on the power of the signal the station generates.


I found this bit of info for you but ill keep looking and let you know what i find out.
Also have you tried it in europe to see if it does work or not let me know ok

How do I manually set my radio stations to my rcart2770 reciever


1. Connect the FM antenna and the AM loopantenna at the back of the unit. Rotate the AM loop for better reception.
2. Press AM/FM.
3. Tune a station by pressing TUNER+/-repeatedly until the desired station is found.Alternatively, you can press and hold thesame buttons down for about one second toactivate the automatic search function. Inthis mode the unit will automatically tunefrequencies until it finds a station.
4. Repeat step 3 to tune to another radio station.
5. Press AM/FMto select between FM and AM.Storing Radio Stations

The unit can store up to 40 radio stations (30 preset stations for FM and 10 preset stations for AM) in its memory. You can enter every single radio station yourself or the unit can store all available radio stations automatically in ascending order

Automatic Preset Programming
1. Press AM/FM to enter the AM/FM mode.
2. Press and hold AM/FM for two seconds to start automatic preset programming.
3. Radio frequencies will be browsed and radiostations stored automatically. When all the available radio stations are stored or all 40(30 preset stations for FM and 10 preset stations for AM) memory locations are full,the auto preset programming function will stop.

Manual Preset
1. Tune to a radio station (see "Manual tuning"for details).
2. Press MEMORY. While the Program Preset number is still flashing, input your desired preset number using the numeric buttons or press CH+/-, then press MEMORY to store it.

Retrieving Preset Stations
1. Press AM/FM to enter the Tuner mode.
2. Press CH +/- to search up or down for thepreset stations or directly press the numeric buttons.

2013 Santa Fe Sport radio on am 670 cuts out and back in with varied times off. If I toggle to the next station and back it is there right away. The station does not have a problem on my other car. This is...


cuts out ?
well, all FM radios cut out for.:
1: weak station.
2: stereo can not be held in properly( can be bypassed on most RAD , pick mono)
3: AGC drop out, same as #1

on better radios (RTM) you can defeat these default features.
set the FM to mono channel mode, and now you hear all stations.
also kill the AGC mode. this allows you to hear
the station. and static or both. like a Marconi radio of days of old.
modern radios are programmed to blank weak stations.
tis a fact. im a tech and tuned these features, for 50 years.

ok the fix,
1: move closer to station
2: get a better antenna (vast choices)
3: go to station and turn the gain knob up and get arrested by FCC.

How good is fm tuner reception? We live approx 50 miles from transmitters and have trouble getting clear signals. Is Bose just good sound quality, or does tuner provide superior reception?


I live in Vail Az about 110-120 miles from Phoenix Az I can pick up 60% of the stations decent. The power cord acts as a fm antenna. Plus this Bose Wave CD/MP3/FM

USA - EUrope FM band stations frequency differences


I have a car stereo purchased from the US and I can’t pick up all radio stations in Europe/UK, what can I do?
If you have purchased a car stereo from the US you will find that it will not pick up many European radio stations. This is due to the fact that US radio frequency steps are different to here in Europe.
You may be able to set the tuner to European stations by following this procedure.
Press and hold down the SRC button to power down the unit completely.
While the unit is off press button 1 & 5 together, while momentarily pressing the SRC button.
If this does not work try the following proceedure;
Press and hold buttons 1 and 5 together, while momentarily pressing the reset button.
If this does not work then the unit is not designed to pick up European frequency steps.
