Question about Sharp Audio & Video Receivers

1 Answer

I have a Sharp VZ 2500. The drive belt lies in pieces at the bottom of the player, so I can assume it needs replacing. I've bought the belt, but have no idea where it goes. Can you help?

    Oh my word! It's working! Damn, this thing's loud. Thanks so much for the instructions, they were bang on.

    It skips a fair bit, and feeling the needles, I'm guessing they need replacing. Any pointers, again, would be much appreciated.

You have to remove the front cover first. then detach the two wire connectors attached to the turntable circutry. Also detach the pushbutton pannel. remove the two screws that fix the top plastic cover inside the turtable housing. then the two big screws that fix the turntable to the main body will be visible. remove them and you can detach the turtable unit out. then remove the circuit board behind the turntable. you can then put the belt between the big disc and the motor pulley on the corner. Good luck

The issue is, that I purchased a set of 2 belts via eBay for my deck. I fixed the problem with the belt to move the cassette. But there is a second set in the pack and I cannot install this. Perhaps it is...


The belts you have replaced are used to operate the loading/unloading mechanism I assume. On the bottom of the cassette mechanism you will find the other belts...one from motor to idler wheel assy. or actual reel hub. Older cassette decks also used a belt to drive the tape counter mechanism.

On my thomas pacconi classic player, the c d drawer or tray won't slide out when I press the open button. It tries, but won't open.


The belt has either stretched or broke. It's quite any easy repair depending on your technical ability.

Open the case and remove the cover from the CD Player (if it has one). Towards the front you'll see a drive motor with a belt to a drive wheel. If the belt is in one piece just remove it and get one a bit smaller in diameter with the same cross section (probably 1.2mm Square). If its broke then measure the length and divide by 3.142 and round down.

e.g 74mm / 3.142 = 23.55 so you'd get a 23mm belt.

They're only cheap so may be worth getting a 22mm also just in case it has stretched a lot.

I have an old SHARP HK-9000 Multi-purpose Music syatem...we cant find speaker connectors on the rear. The speakers are detachable and dont have input jacks, just bare wires. Where do they connect??


The speaker wire is supposed to be connected to a mono right angle 1/8" male plug. It resembles the same plugs at the end of headphones used for all sorts of walkmans, cd players, mp3 players... But the plug on your speakers is mono so instead of there being two bands on the plug for stereo, you need the mono variety, the one with one band. They plug into two small female holes located on the bottom rear of the boombox. You might see some small black plastic clips along the bottom of the boombox held in place by one screw. These things are meant to keep the speaker wire from hanging out from the bottom of the boombox.

Record player not working


Hi Allan,

Unfortunately it sounds like the belt either broke or is slipping. If you're up to it, you can order a replacement belt from a few different places online. As I haven't messed with a turntable in years, I can't make any personal recommendations. A quick google search returned this company, though... http://www.turntableneedles.com/

You'll need the current belt measurements before you order a replacement. And, disassembling the unit will confirm if the belt is broken or just slipping. (Or, better yet, slipped off the pulleys!)

Keep in mind that replacing the belt can be a daunting task.

Good luck!

Sharp cd-ba1600 door won't open err 0201 displayed on screen


The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit. If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them. If you have the proper tools and equipment, the first thing to look at is the RF pattern of the unit while its playing. It should be a sharp and clear pattern. If it's dull and smeared, then the laser could be weak.
Also, in these units are very critical alignments called the focus/tracking gains and offsets. When these alignments are off, it can often cause intermittent troubles. As the unit ages and parts change value, so do these alignments, and will need to be checked. In my time as service technician repairing DVD/CD players, 65% of the laser pick-up assembles I have tested were good and only needed a small adjustment. Today's technology makes it unfeasible for a shop to hook up a DVD/CD player, and even some recorders, to their equipment and make these adjustments because of the cost involved.

Hope this may help;

I have a Sharp CD-ES900 CD Shelf System and when I turn it on it the lights flash and it powers on, but then it turns off about 3 seconds later. How do i get it to stay on?


To clean the lens you must use very little pressure. Take a cotton swab and barely moisten it with plain, non-scented, or oily type alcohol. In a swirling motion, very gently rub the lens until you’ve covered it entirely. Then repeat using the dry end.
Now, if no cables are disconnected, and if you can verify nothing is touching the TV or DVD chassis, you can plug in the unit and check if this helped the player to "see" again. Most of the time you can check as is, though on the combo units you're going to have to slide the chassis assembly all the way back into the cabinet to get it to work because the cables are often too short. If this didn’t fix the problem, please read on.
Other things to check
If the cleaning didn’t help, don’t despair just yet. You can see if there’s a problem elsewhere in the unit by using a few simple tricks and tips.
First thing you want to see if the unit’s laser is in good working order. This method isn’t foolproof, but most of the time works admirably. When you insert a disc, see if you can look up underneath where the disc sits on the turntable. Observe the laser lens going up and down. If the lens is trying to focus, that’s good! After a few seconds of the lens trying to focus, the platter should start to spin. On almost every CD/DVD unit I've encountered, the unit won't spin unless the laser has properly focused on the surface of the disc.
f the unit spins up and and then shuts down, you should check and make sure the laser pick-up assembly slider mechanism is working without any obstructions and that the small chrome rail that it slides on is slightly greased. Don’t go overboard with the grease though, as too much can cause all sorts of problems.
The slider mechanism, depending on the age of the unit and the manufacturer, consists of the small chrome rail, a drive motor, a small gear assembly, and (in some units) a small belt that drives the slider unit via the motor. This small belt causes all sorts of problems. If the belt is broken or slipping, it can cause skipping, dropouts, or simply no start up at all. Also, if the belt breaks in the middle of the disc, the drive mechanism gets hair or dirt wrapped up into the gears, or the pick-up assembly doesn’t return to the start position (called home), the unit will (99% of the time) refuse to release the disc, causing it to become stuck inside the unit. There’s a little micro or leaf type switch located at home position that sometimes gets dirty or breaks and, causing this problem also.
If the disc starts to spin slowly and doesn’t come up to speed, the spindle motor that’s attached to the turntable platter is a common problem. There could also be a problem with the spindle motor driver controller IC or the power supply regulator that supplies voltage to the driver IC. If the disc starts to spin and then spins really fast, or stops and starts to spin backwards, your problem is the laser pick-up assembly or the servo control circuit.
Also, in a DVD/CD player there are many complaints where the disc gets stuck inside of the unit. This could be as described earlier, but there’s also what’s called a drawer/disc tray opener and closer mechanism to contend with. On many models, old and new alike, there’s a small belt that goes bad and wont let the tray open. You can usually put your ear very close to the front of the unit and, if this is happening, hear the motor spinning when you press the eject button. Another cause is the nylon gears, which can get jammed up with dirt and dust. Also, in other cases, you could have a motor problem, or the driver IC could be at fault. If you suspect that the motor is at fault, simply measure the voltage on the tray motor while pressing on the eject button. If the voltage comes up between 6 to 12 volts, depending on the manufacturer, then the motor needs to be replaced.
Alignments
If you continue to have problems after cleaning and checking the other things listed above, you may have a problem with the player's alignment. Of course, one of the problems you'll face checking alignments on a DVD/CD player is that you’re going to need to use an oscilloscope on most of them.

Faulty turntable


Hi Roger It will need a new turn table belt. They are an odd size, but can generally be bought from a good spares part supplier. Let me know where you are and i will be able to steer you to a parts agent that can organise one for you. Thanks for using FixYa. A "fixya" rating will help my profile and create an incentive to get the parts source organised for you;)
