Question about Sony CFD-E75 Cassette/CD Boombox

No power to unit

When I attempt to play cd or radio, it starts then fades away and the lcd display goes blank. If I hold the end of the ac power cord at an angle where it enters the unit, sometimes it will play. I know that the cord is good (I used one from another Sony unit), so I'm guessing it must be the ac inlet inside of the unit. Would this be correct and if so, where could I find a replacement. I've opened the unit and looked at the inlet plug, but did not observe anything. Thanks!

Remove the power plug and reopen the unit. Usually the socket will be soldered directly to a Printed Circuit Board. Look in the underside (where the solder joints are and you'll see the joints associated with the power socket. One of these is either a bad connection or the solder pad has lifted and broken the track on the PC board. If it's the solder pads give them a workout with a soldering iron if it still plays up scrape the protective lacquer of the PCboard Tracks and resolder them to the socket's solder joints. This should solve your problem. The best way to spot a bad connection is to reinsert your plug (making sure the other end isn't plugged into the wall socket) and lever the plug up, down, left and right. If there's anything faulty you'll see it. The solder joints will move very slightly and if the track is fractured you should spot that too. One other tip is that there is a switch built into the socket which will disable the battery power when you plug the unit into power. I have seen a few of these switches go bad but the chance of that is extremely small. I'd put my money on the socket's solder joints. BMW

SOURCE: My Sony CFD SO1 keeps skipping/display light keeps flashing

That is an electronic problem. Probably a just-about-to-break cable in the motor of the CD drive, that sometimes causes a short and turns off the unit, or sometimes makes it to comport erratically and produce the buzzy sound. If you have electronics knowledge, then you may open and check the wiring harnesses. If don't, take it to your local electronics repair.

Testimonial: "Thanks! In terms of price though? Would it cost as much to get it repaired as the CD Player itself? Or is it a reasonable price?"

How do i enter code on model mod8691mb1

Turn radio on, 1 will appear in the display. Via the 6 preset buttons enter the 6 digit security code. As each number is entered the number will be displayed in the lcd. If the correct number was entered the unit will operate after a few seconds. You get 3 goes then you have to wait an hour to try again.
For the cd- A small No1 & a large No1 will appear on the screen. the small 1 shows the No of code entry attempts
, the large 1 is the first No of the code. Use the track up/down button to change the 1 to the first No of the code. press the play button to store the No. The entered No will move to the left & the No 1 will appear next to it, repeat for all 4 numbers. If the correct No was entered the lcd will go blank & a cd can be inserted.
Hope this gets u going cheers

Hi, I have a 2006 650i The display unit intermittenly goes blank shutting off the radio etc just leaving the BMW logo showing, then after about 10 minuets returns to normal

Short to power. Could be as easy as just pulling a fuse and reinsert it. Sometimes you have to access the plug and do they same thing. Sometimes you have to fix or replace the plug. If your display is the radio, It could be internal radio problems..

LCD display is fading

Run self test and LCD test:
Power unit on while holding MENU/ESC-
press down arrow to TEST then right arrow to start.
When self test is complete use down arrow to go to LCD TEST, then right arrow to start. Press MENU/ESC for a while screen the MENU/ESC again for vertical gray bars. Press MENU/ESC 3 times to exit. The LCD unit is pn 000-145-512, $175. I strongly suggest you not attempt replacing the LCD yourself unless you are a qualified Furuno tech.

When starting computer in the morning, the monitor display flashes analog then digital then back to analog and goes blank. Power to the monitor is on. Multiple on/off of power brings display back.

Hi, 12fixlouie here. LCD monitor may have intermittant solder joint on power supply board inside unit. May only need you to resolder it to fix. Locating it is a whole other problem in itself!!! If not into monitor "teardown" and all the other stuff that you will need to attempt a repair, then let me know right away. 12fixlouie

CD not working propely

"No disk" is about as fatal a CD read error as ther is. Before we assume the player is at fault let's look at our media. A CD should be handled and cared for like any opitical device. Dirt, fingerprints and scratches are tolerated somewhat but the CD standard isn't impervious to problems.

Do you get any constant results with any CD, say one that always works vs one that never works? Compare them visually for problems on the one that doesn't. I use a clean soft cloth with glass cleaner to clean my media.

This is the entire troubleshooting section for the unit.

Care of CDs
When a CD becomes dirty, wipe it from the center out with a
cleaning cloth. After playing a CD, store it in its case. Do
not keep it in hot or humid places.

Troubleshooting
If your unit fails to perform properly, check the following guide
and the relevant sections of the Operating Instructions.
There is no sound.
•Are the speakers and AC power cord connected properly?
The unit shut off suddenly.
•Possibly a short circuit in the speaker terminals.
Disconnect the AC power cord from the AC power outlet
and re-connect the speaker cords correctly.
The unit blacks out when the unit is turned off.
•Is ECO mode set to on?
Erroneous display.
•Reset the unit.
Poor radio reception.
•Check antenna connection. Adjust the antenna to find the
best reception.
•Move unit and antenna away from other electric appliances
and cords.
The tape does not run.
•Is the deck in pause?
Poor tape sound.
•Check for dirty heads. Clean them if needed.
•Use type I (normal) tapes.
Cannot record.
•Is the erasure prevention tab of the tape broken off? If so,
cover the detection slot with adhesive tape.
The CD player works poorly.
•Is the disc correctly loaded?
•Is the disc dirty?
•Is the lens affected by condensation? If so, wait
approximately one hour and try again.
Resetting the unit
If an unusual condition occurs in the display window or the
cassette deck, reset the unit as follows:
1 Press POWER to turn off the power.
If the power cannot be turned off, disconnect the AC power
cord, then plug it in again.
2 Hold down s and press POWER.
Everything stored in memory after purchase is cleared.
Condensation
Moisture may form on the CD pickup lens when:
•The unit is moved from a cold spot to a warm spot
•The heating system has just been turned on
•The unit is used in a very humid room
•The unit is cooled by an air conditioner
When this unit has condensation inside, it may not function
normally. Should this occur, leave the unit for a few hours,
then try to operate again.
