SL5 refers to the linear tracking Turntable. There is a service manual for the CD Player https://www.google.com/search?safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk01Ht7MAibqzcVp6tdmCktF5JA1flA%3A1610575721168&ei=aW__X4_ICdyg5NoP24CEqAs&q=technics+sl5+mc+50+cd+player+manual ..

hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops

Be sure that the EQ settings aren't accidentally putting you over the top as far as demand is concerned. Bass-heavy material? Same conditions apply...accordianman

Go down to Walmart and get CD Cleaning Disc. They have little brushes that clean the optics. Or it is a counterfeit copied disc and has become corrupt! Try the discs on another unit.

If it does not power up you need to check the power supply and/or associated fuses.

Display or control board failure

its cd lens weak or defective solution replace lens

I know it's late but i happen to have received the same unit for free, and it had the same problem. The reason for the message is that the laser weakens over time and cannot reach the CD anymore. If you try holding a disc directly above the lens, to the back of the spindle, you will see the motor starting to spin. That means the laser is still working but too weak to reach to the height of the spindle. The solution is simple. Take the drive unit out and remove the three screws on the board at the back of the drive. Carefully lift that board, there is a flex cable connected to it you don't want to break. You will see a little variable resistor with three pins. Measure the single pin against both of the other two. One should read 3.something kOhms, the other 1.something. Mine read 1.35. Using a small screwdriver turn the resistor to the right until the side that read 1.35 reads something around 700 ohms. I left mine at 740 and it works fine. Put the drive back together and load a disc. It should now work again. Don't set it any lower than 400 or you will damage the laser. If it doesn't work with 800-400, the laser is probably damaged and the drive needs to be replaced entirely, which is not worth it.

Save yourself $$$. Go to Ace hardware and get an O ring for 50 cents nstead of the $10 plus $3 shipping some websites want. 1 and 1/16 size. Have replaced these on a couple of technics SL MC models and works like a charm. No more error codes.

The player has failed. The new belt can't revive it.

The disk drive is defective.

Probably drive failure so no, there isn't any hope

The direction is changed when the motor driving the tape spool senses resistance such as when the tape reaches the end! If the tape you are testing it with is ok then it could be the motor needs cleaning or replacing!

nahosa is a spammer on FIXYA that needs to be removed. Troubleshooting guide for that model only suggests moving volume control if two dashes appear = https://www.manualslib.com/manual/169267/Technics-Sc-Ch900.html?page=75#manual

Hi Robert, probably the cd tray belt (a tiny black rubber belt that connect the tray rack with motor gear) is broken, check this by opening the player, if torn you need to buy a new spare and replace it.

I called panasonic and they told me to do a hard reset on the system it seems to have worked on mine. Hold the power button continually while you unplug and replug the unit.
