Open Question

CD's load but "no disk" comes up on dislplay

The tuner and tape work fine. The "roulette wheel" open and turns just as it should. But when it goes to play any of the three CD's, the message "no disk" comes up on the LCD panel for all three positions, after a 5 second interval. I took the unit apart but didn't find anything besides the piece of tape that held the rear ribbon cable had come loose. My gut feeling is that there is an optical component (LED?) that is supposed to be blocked by the disk and is not responding, but I don't want to start poking around without a little more guidance. There is a light inside the top that is working, but I don't know if that is decorative or part of the detection circuit. I don't, of course, have a service manual or even a schematic. The unit was given to me, so I don't want to invest $25 for a service manual, only to discover that it is a board level problem that can't be fixed. Thanks, Mike

SOURCE: Intermittent Power Problem when playing CDs

Hello db1964,

I have a cdf-e75 that had a similar problem, although the red power light was dim for all functions. (the radio, tape and cd)
After opening up the unit and inspecting, I found one of the pins on the printed circuit board for the power had broken away from the solder. (it is a tiny board where the AC connector is soldered to) Seems in my unit there is nothing securing the molded AC connecter to the plastic case except the the printed circuit board it is soldered to-It is a poor design; perhaps your is the same? I suspect over time pushing the AC cord into the back of the player may have broke the connection? Anyway, I soldered the connection and I have never had any additional problems as the unit has worked fine since.
Don't know if this helps, but my suggestion would be to open the unit and inspect the pin connections on the AC printed circuit board to see if any have a loose/broken connection. ( Mine was not noticible with the naked eye as I had to use a magnifying lens and a bright light. Hope this might help.

SOURCE: Cleaning Optical Block

Sorry to be teh bearer of bad news, but the optical block (light engine) can not be dis-asembled outside of a cleanroom. You can remove the rear cover of the set and clean the mirrors and glass. That may help, but usually these typesd of symptoms are an indication that the light engine is starting to fail. The light engine can be replaced by you if you feel comfortable. The part is still available.

Keep us posted.

I have a Samsung SCM-7450 Hi-Fi System. The CD player has stopped recognizing that there are CDs ready to play. Any suggestions?

There is nothing you can do and I doubt leaving the CDs in the unit would have made any difference with the problem you have now.
The CD player is an integrated unit with tape player, turntable etc so there are presumably no connections on the back of the unit that would allow you to connect a new CD player and run it through the unit. However, if it does have compatible connections then that is what I would do.

VHS Stuck; Cover is off; nothing moves...wheels, tape...nothing...help

Unplug the unit, then plug it back in WHILE holding down the EJECT button ... The tape should come out unless there is a belt broken, missing, or loose.

I have used old, inoperable VCR's for tuners only as well. What happens if you leave the tape in all the time? Does the tuner work like that?

1983 Cadillac Sedan deVille radio cassette player problem. The cassette player gets stuck in forward position and makes a clicking sound but no music. The tape does not turn. Belt seems to be fine. It will...

If the belt is fine then the pinch roller must work to pull the tape with the capstan working.
so please open set and get glimpse to see if the pinch roller is engaging. If not the loading mechanism is not working. you will need to see if the reel drive is also working. So unless the mechansim is checked there is no question of the sound coming out.
So see that the loading engages the pinch roller to pull tape and the reel drive to gather the winding, if not reset loadding mechanism .
However if the tape moves and there is no sound then the head preamp, the tone amp or the output amp can be faulty. You can use a signal test to confirm the section.
credit if this helps

ADX5355 clock

you just have to turn the power on, push the display button so the time is showing on the display. (The only buttons involved are the "BAND" button, the number 4 roulette button which is the top right station preset button and the "DISPLAY" button.) I think you push and hold the BAND button and while holding it push the number 4 roulette button. (you don't have to hold it for any specific time you just have to push BAND in when you push the number 4 roulette button.) the time will flash and you use the vol/seek knob to adjust the time. When done push the BAND button again.
=> This really work, thanks!

Unit will not start or load disc

Try opening up unit and using canned air and blow it out - sometimes simple dirt causes things like this While inside glance and see if you don't have some old tape or bits of labels that have come off and are anywhere inside that might be hanging the various working areas. Try using cd cleaning disk and vhs cleaning tape Without seeing this not sure what is causing it but may be something simple like the dust or pieces of label causing problems or the little rubber "tires" and other rubber components having gotten stretched out and slipping.
