the problem is in the front buttons of your tv set ,program buttons may be up or down got stucked.unplug it and clean the sorrounding of the buttons if some sticky dirt found.it usually happens when while you are eating and changing a program,your finger tips have some sticky substance that adhesed to these buttons while you are pressing or maybe the kids...
The tar like sticky substance is the suspension of the speaker cone and there is nothing wrong with that. Its doping compound applied by the speaker company to damp the speaker ( Was it not always there? ) If the suspension has come off the bass notes will flutter, if not its some other problem. Play some music and put your ears near the tweeters flared horn to see if they working. Nearly 30% of your sound comes from the upper part and if you have damaged it there will be a volume drop. These speakers are quite complicated on the inside. It has two amplifiers, one for the woofer and one for the tweeter. It also has a digital sound processor. Any thing could be at fault, even a simple wrong setting.
I'm not familiar with this specific turntable but there are some general tests that you can try. As with any problem try to identify the source of the problem by working through an elimination process.
Does the problem occur at all speeds or just one, which would indicate an issue with the belt drive system.
Does it squeak continuously or only at certain points as the turntable rotates? Put a marker (a lump of blue-tac would work well) towards the edge of the turntable and note the point(s) where it squeaks.
Rotate the turntable by hand with the power switched off, vary the speed you rotate it at. Can you feel the squeak as well as hear it?
Is the turntable on a level surface and is the turntable itself level (parallel) with the base - if it is not this might suggest that one of the suspension mounts has failed. Peer under the edge of the turntable all round to make sure it is not rubbing against the frame / base.
The turntable is driven by a belt system off a separate electric motor. Usually these motors are hung from the frame on a sort of elastic band arrangement. These bands become perished and can break or just stretch unevenly, which causes the motor to hang at a funny angle. Sometimes this can result in either the pulleys rubbing against the side of the frame (would normally be a fairly continuous squeak). At lower speed settings (e.g. 33 rpm) this may also cause the edge of the drive belt to rub against the bottom of the larger (45 rpm) pulley above it. If you can't find a supplier of the correct replacement motor suspension band you may be able to fix it with ordinary rubber bands but it may take a bit of fiddling to get the motor perfectly level at exactly the right height.
With the motor running and the turntable rotating gently press on the rim of the turntable with your finger as a brake to slow the turntable down slightly. Does the squeak increase or decrease in volume or pitch? If it gets louder or higher pitched that probably means that the drive belt is slipping slightly (in which case some records may sound a bit slow when you play them). You can either replace the belt or purchase a can of 'belt dressing' spray (obtainable from most good tool shops) and apply a light coating to the inside surface of the drive belt - don't over do it. The best way to do this is by rotating the turntable by hand whilst gently squirting a little of the spray onto the belt close to the point where it goes on to the pulley on the turntable drive spindle. Take care not to get the spray on any other moving parts or the electrical components as it is sticky and hard to clean off. If this is the problem you may need to re-treat periodically.
The motor and belt drive system may be accessible either by lifting off the turntable deck (platter) itself or by turning the whole thing upside down (make sure you secure the pick-up arm before you turn it over!) and unscrewing the bottom of the case. Some turntable platters have viewing holes in them which are revealed by lifting off the rubber mat.
Gently slip the belt off the pulley wheels on the motor and on the bottom of the turntable spindle. Check the pulleys for any lumps of dirt or fluff that may be causing problems. Also check that the drive belt is clean with no lumps or flat shiny spots. If the belt is worn replace it.
If appropriate turn the turntable up the right way again.
Rotate the turntable by hand. If it still squeaks the problem is in the turntable bearing and may easily be solved with a bit of lubrication. Some manufacturers will supply a little tube of special grease. If you don't have this a bit of Vaseline /petroleum jelly will do quite nicely. Don't use a silicon based lubricant like WD40 as this will dry out again over time.
Try rotating the motor spindle by hand - if it squeaks there may be a problem with the motor bearing. These are not usually serviceable and will need replacing.
With some turntables the belt runs through some little guide wheels between the pulleys on the motor and the turntable drive spindle. These may need lubricating with a little VERY light oil. Sewing machine oil is perfect for this. Only use a tiny drop applied to the axle of the guide wheels with a very fine paint brush. Don't use to much or use anything in a spray can as it might get on the surface of the pulley wheels where it will contaminate the drive belt and cause it to slip.
You will need to lift felt on the platter section exposing the platter. Next you will need to pull upwards on the platter itself. The rubber band goes around the inside of the platter and onto the spindle motor. To replace, simply lift platter section of the unit, place the belt around the inside of the platter and replace the platter. Move the platter around till you see the motor and use some tweesers to pull the belt over the motor. Hope this helps
Normally the belt does not go through any special tensioners or anything of that nature,The belt should go directly from the spindle motor onto the inside of the platter. Hook the belt on the motor section and lay the belt open wide inside the turntable. Next, replace the platter and manouvre the belt onto the platter inside, through the two large holes
if it is black and fairly long it's probably the drive belt and it has likely become stretched (or sticky).The belt fits on the inner circumference of the platter- to re-install - remove the rubber platter cover and platter
-stretch the belt around the inner (botom side inner) lip of the platter
- you should see the motor facing up with a brass capstan or drive bobbin
-from the top side of the platter stretch the belt slightly off the platter through the openings provided and while re-installing the platter loop the belt over the motor bobbin.
If the belt flops off the inner platter it's to stretched and a replacement would have to be ordered
clean the spindle with alcohol and put a single drop of thin oil at the bottom of it
the sticky stuff is the rubber corroding
if the belt is not too stretched , boil it in water with some vinegar for a couple of minutes , if its too bad then replace it
