Question about RCA RT2280 System

1 Answer

Presets stopped working

Preset function doesn't set the presets, and the tuner doesn't stop on powerful stations. It remains set on various, seemingly random FM and Am stations.

When you click the stations manually to a good station, it sounds great. All other functions seem ok, though I haven't gone through very many functions.

    Thanks Tech48.



    I happen to have been in elecronics a long time too, and I understand what you're saying.

    When I get a chance, I'll see if cold solder joints are the problem.



    The unit had been unplugged for a couple of days, so that isn't the likely problem, but I might try again just to make sure.



    I appreciate the thoughtful explanation.

I have repaired a few of these receivers in the past few years and have found several with microprocessor issues and some with a lot of heat stressed solder connections on the main amplifiers board around the voltage regulators.

The problem you are having is similar to problems the others I have repaired were having.

There is nothing you can, as an end user, do beyond a hard reset of the microprocessor by unplugging the unit from the wall and wait about an hour or 2 before you plug it back in.

By resetting the microprocessor you can at least see if the problem is a minor one or not. most likely it is an electronic problem that will take some good troubleshooting skills.

The bigger problem you face with this particular unit is that RCA no longer supplies parts for the audio equipment they sell.

Once the supply of what they have in stock is gone, thats it, no more parts at all for RCA audio. That supply has not been replenished in around a year.

All of the RCA audio equipment sold now is exchange only if it is under warranty.

I know this because I work at an authorized RCA repair center and I am the audio tech. I have not repaired an RCA audio unit under warranty in about a year because of that.

I have fixed 3 or 4 of the same unit you have, but not under warranty.

If you or somebody you know has very good soldering skills you can try reflowing the solder connections on the main board and even reflowing the microprocessor. It could solve your problem, but not advisable unless you are very good with a soldering iron and have done this sort of thing before.

I am sorry for this rather bad news, but it is true. I have been repairing audio equipment for over 17 years and am very familiar with RCA products.

If I can be of any further help please let me know.

Cannot format or reload factory presets after it stopped working


The card that you used to transfer the files HAS to be (1) FORMATTED by the ESX-1 unit FIRST, (2) then put the card into your computer's card reader and download the files. (3) Put the card BACK into the ESX-1 and try reloading the factory presets. Good luck!

Advice on how to set tuner presets on AlpineCDM 7838R in car stereo CD . Unit has both permanent and switched power supplies, will search stations and hold them when switched off but cannot work out how to...


some of the alpines had an odd way of setting the presets manually. you need to press any of the 1 thru 6 buttons for a few seconds. when the display starts blinking just pick which preset button (1 thru 6) you want to set the station at and press it once.

LG LX-M240 operating instructions: I cannot set the presets


Owner's Manual is PN 3834RH0020U
On pg13
1. Press TUNER/BAND to select AM or FM
(Leftmost rectangular button on left of volume knob)
2. Select station by using TUNING +/-
3. Press PROGRAM/MEMO on the remote
A preset number will appear.
4. Press PRESET +/- (or PRESET ^/v on remote) to
select the preset number you want.
5. Press PROGRAM/MEMO again. The statio is stored.
6. Repeat above for more stations.

Believe you can store up to 30 stations.
Stations on presets 1, 2 and 3 take longer to 'kick in' when listening to the radio
as they are the 'tens' prefix for the preset numbers. 4 - 9 'kick in' immediately.

Set Radio Station Presets


Try just holding the button of choice down. In my Audi, when I had a factory head unit, to set for example, preset 2, I'd just tune to the station I wanted to program, and then hold down the number 2 preset button until the display stopped blinking. It was then preset.

Most times it goes like this:

find your station by manually searching the frequency. When found, press the memory button and in your display the word memory will flash. than press the number you want it stored under and hold it pressed untill the flashing stops.

Other option:
once station is selected, press the preset number and hold it untill you hear a beep or, if the number flashes on your display, it stops flashing.
often you have the possibility to store aprx 10 presets on 1 band, by seleting the band you get new presets for each band, geeting in total 40 preset possibilities.

Let me know if this solved your problem.

Need an owners manual


to set the 5 main presets:
with radio on, use the manual tuner to find station you want on a preset. push and release mem/clock adj button (mem will flash on display), push preset number and while holding it in push the mem/clock adj button again (mem on display will go away). station is now preset to that number.

to set the 5 additional presets:
with radio on, use the manual tuner to find station you want on a preset. push and release the +5 button (+5 will flash on display), push and release mem/clock adj button (mem will also flash on display), push preset number and while holding it in push the mem/clock adj button again (mem on display will go away). station is now preset to that +5 number.

to set the digital clock display:
with radio off, push and release the mem/clock adj button (clock display will now flash), use the tun up / hr part of manual tuning button to adjust hour and the tun dn / min part to adjust minutes.

How do you delete the presets in my unit?


Hello,

I was looking for a solution of my problem but found your problem. I have a manual but it is not aesy to find a way to erase all presets. Read this selection till the end and you know a way!

It is possible to change the MW tuning interval. You can do this by pressing the POWER button while pressing the BAND button during power is on. To reset the interval, repeat this procedure.

NOTE

- When the MW tuning interval is changed, all preset stations are cleared. The preset stations have to be set.

Good luck!
