1. I have a sherwood cartridge style changer from the 80's like to cdc-1000c. I'thou not 100% sure on the module correct now but I'll certainly get that. Information technology won't read discs, doesn't matter what disc. I know nothing most cd players. I have repaired vintage tv'south a niggling and then I take electronics knowledge. To start with are there some common universal things I should look for?

2. Start by cleaning the dust off the laser head.
   I utilize alcohol solution and tissues used for cleaning eye glasses.

   My cd play took a crap shortly after I was standing drywall chemical compound. They don't like grit.

3. It may be a lost cause. Definitely cleaning grit out is the first try, but it may also have had the lubrication dry upwardly and the guide rail sled is worn, or the plastic warped, or broke, or the motor isn't at speed or wobbling due to shot bushings, or if in a (vehicle) loftier humidity environment, electrical oxidation became excessive.

   Frankly I would abandon it, convert the CDs to MP3 or FLAC and get an inexpensive SD or mSD carte reading playback module off eBay if not an entire head unit of measurement that can take memory cards, or bluetooth from a phone/tablet/computer/whatsoever as the source.

   Gotta luv tech, today you tin fit hundreds of CDs worth of music on a card the size of your fingernail

4. Except that dont love tech. Unless its old tech. Vast majority of my stuff is on vinyl. Im still fixing it if at all possible.

5. The CD actor wasn't vinyl and has no audible difference to flash retention stored data. It'southward now just a more failure decumbent, far more infinite, cost, weight, and less power efficient mode to store and read data. If you'd rather a record player, practice so.

6. Take a conscientious expect at the lens (as stated above) and see what happens when it tries to read a disc. Many times, but leaving the comprehend off will allow you lot run across all yous need.

   If cleaning the lens doesn't work, you may see the disc speeding upward and slowing downwardly, and the head moving back and forth.

   Report what you see (and the lodge in which it happens) and that may give us more information. For example, if the disc doesn't spin at all, that's definitely worth noting!

7. Sir Gstutz44 . . . .
   
   Should information technology be that you lot haven't touched the unit still . . . do find these precautionary CAVEATS.
   Get skillful lighting for initial observations and note the convex lens.
   It is being electromechanically and magnetically controlled such that it tin make MICRO, and that is HEAVEEEEE on the micro movements, such that information technology can slightly motion in both the X and Y planes, in addition to moving the lens up and downwardly / in -out for FOCUS.
   The X plane motility relates to a dual symbiotic working relationship between the use of a pb screw drive , that is always playing " take hold of upwardly " to the express electromechanical movement range that can be made to the lens positioning by its electromagnetic mechanical positioning .
   Working in tandem, they combine to make a smooth reading / tracking of the units lens to the disc surface.

   If the meridian of the lens has eventually accumulated debris resting upon its top, it'southward just like having a muddied pair of reading glasses. . . . relating to the adverse effect of the CLOSE proximity of that deteris to the lens of the eye.
   A pencil held at an arm'southward length is no not bad impediment to your optics panoramic view, merely i held at olfactory organ length is creating 1 hell of a blockage of vision.
   Plus, the condition can be farther aggravated past airborne drifting of cooking greases, cigar or cigarette smoke and their accompanying balance depositing upon the lens superlative within the unit.
   Wood burning fireplaces say . . . me also . . . ME As well !
   Plus . . . . every one . . .particularly as a child . . . has seen Strong direct sunlight flooding into a room and the resultant micro crud fibers that are aimlessly floating most in the air, after a person has moved thru their path.

   LENS CLEANING . . .

   I use a Q tip that is wetted in either denatured alcohol or ***** isopropyl alcohol *****, and I prefer the Q-tip that is a bit loose in its wound fluff, every bit compared to the REAL BONEY-FRIED Q-tip which seems to be quite tightly wound. In that case, I pollex-finger massage information technology a bit . . . . through an isolating paper towel . . . to loosen up its fluff.

   Remainder the side of the hand to be used, on the unit of measurement such that your grasping thumb and fingers tin can merely attain to the lens and hen make uber controlled 1/8 inch ( seeing that you are . . . Amerikanski . . no metrics involved ) circles with its tip.
   Put no more pressure upon the top of the lens, than is being needed, to see the very-very short 10-Y limits of motion / swing of the lens.
   This AIN'T being no Bull in the Cathay shop category of work. Rotate the tip in quadrants so that 4 clean surfaces
   get to make clean the lens surface, which should be totally clean by that time.
   Set aside the unit of measurement for drying time, then test out.

   ILLUSTRATION . . . . .
   Lens + its Magazine drive coils + some lateral gristly deteris, off to the side., now being non obstructive . . .

   

   AT NO EXTRA Charge . . . . .

   TIMELESS TECHNICAL TIP. . . . . or . . . . . . . a secondary apply for that dormant power supply just otherwise . . . . . setting on the lab shelf
   
   ***** 100% isopropyl alcohol *****

   You buy . . . velly-velly Cheeeeeeeeeeply . . . .on sale . . . .lxx% Drugstore isopropyl booze + brand dual strip, close spaced long, flat plate stainless steel electrodes, with 2 connected leads and assistant plugs on the leads ends + 12VDC or more than ability supply then leave bottles cap off and plug up the bottle tops hole and resultant 2 compressed wires at its sides with a flexible micro cellular sponge flake plug --------> Yields ---------> electrolysis decomposes, all of the water content and is making 100% isopropyl alcohol, with time.( Lookout the decline in current consumption )

8. Aye sir I do realize theres no existent difference in audio quality. I promise no offense was taken past my previous comment as I meant none and so I apologize. I just adopt equipment I tin can get my hands on. Though I exercise have some new stuff. I just plain prefer vintage. But yes you completely right in what yous said. I wont contest that.

9. I had a similar problem with my old Pioneer PD 9700, the disc wont play at all. The first thing I did was to check the lens on the pickup associates and to my surprise it had fallen off it's sitting base. I carefully glue information technology back using a fine drop of KRAZY glue afterward blowing off any grit inside where the optical prisma reflector is allocated. The Infra red axle comes from the diode which is a double setting diode, one for the PD (photo diode) and the other for the LD (laser diode). The latter is the one which detects and reads the CD get-go at a wavelength of some 780 nm or and then and a 1mA output. If the CD is non properly sat on the disc tray then the beam volition not activate the second diode (PD) which in fact is the 1 reading the disc chip stream content. Some CD players have a examination way setting to right any bug concerning alignment, focusing and so on (check the service transmission of your device), essentially used when you lot are replacing the whole pick upwardly assembly or when you are certain at that place is an alignment problem (i.eastward. the disc wont play correctly or in that location is no information almost the disc on the front displayed panel. Notwithstanding, it is extremely rare a diode fails unless you use your CD thespian 24 hours a day!, therefore it is worth checking outset, both alignment and any marks or grit on the lens. You could also bank check the carmine light coming out of the lens using your smartphone photographic camera, therefore fugitive eye naked exposure. The way you should practice it is turning on the device with your camera pointing to the lens. Press play and the LD will send the first beam light through the lens for about a second or two. If you come across light through your camera then the LD section of the diode is ok. Information technology is worth noting that the infrared beam could be diverted if the lens are scratched or muddy, rendering the IR light becoming out of focus. If the lens is opaque, and then y'all should just clean it up using ordinary windscreen liquid and a piece of cotton wrapped on a tooth stick. Avoid whatever unnecessary pressure on the lens as this is sabbatum on a balancing housing, but rub it up gently with the cotton wrap tooth stick dampened with windscreen liquid . About of the times, dust or finger marks on the lens causes CD players not reading discs properly or playing it at all. The second matter to check upwardly is the CD tray compartment, especially if your CD Player is old. The parts to look at first are the screws, washers and most importantly lubrication on the conveying section. Retrieve, if the disc tray is not properly saturday or lubricated then the IR axle may be out of focus or unable to read the disc. In my case, my Pioneer was manufactured in 1991, so it is quite old. Upon checking the washers which are rubber kind, I noted there was one showing habiliment and cracks on information technology so I replaced information technology straightway. After conscientious aligning of the set up of screws property the CD in-tray section, the former Pioneer came to life again!
