Can mp3,ipod connect to philips FW-R7 with cd

All you need to get them to play is a "dock" and a 3.5mm Jack to two RCA phono plugs lead.
The Jack goes into the headphone output and the RCA's go into any spare socket on the back of the unit IE tape/cd.
Infact you just need the lead, plug it into the headphone output of the Ipod or MP3 player. But the dock will keep the battery charged and you get a remote with the dock, so you don't need to get out of your chair, to operate the player.

I have a rca rs2640 stereo system. The display, cd player, tape player, radio, and headphone jack all work. But when a cd, tape, or radio is playing, the speakers do not make any sounds. I know it is...

It sounds like maybe you have speaker wires touching somewhere. If they are touching it will blow fuses, especially if you turn the volume up to try to hear anything. DO NOT put bigger fuses in to replace the old ones, you will actually do more damage to your system because a higher volt fuse will allow a higher voltage to "spike" in your stereo and might just start frying internal parts.

Loud buzzing when I insert a tape in my car's stereo

Hiya, first try a normal cassette, see if that plays OK. If so the deck is probably fine, if not then the deck is faulty (probably not serious though and just a loose wire on the head).
If the connection between the tape and MP3 is a cable, the fault is quite likely there (if bluetooth then not). I strongly suspect the cable from the previous issues also.

Best of luck

My Compact Disc Stereo System NSX-AJ50 is tripping off every time I turn it on. Henry Thanks.

One or more of the output transistors has failed or you have a bad speaker. Try disconnecting both speakers and turning on the unit. If it still shuts down, then the transistors are likely to be defective. These can be replaced for about $15-$25 plus labor at any service shop that handles audio gear.

Tape player not working

i have had this problem with mine what you can try is when it does the clicking sound you can take your fingers reach under the black part w/ the head and gently push up when it clicks if you hear more clicks and the part moves then try pushing and holding the tape switch located at the left or right top corners of the player then press play if the head goes up but the clicks 3 times fallowed by 6 clicks the repeat the process. what is going on is if they r not use it tends to lock up

No sound

Have you checked if this is only when you play CDs or also if you play Tapes or Radio? If sound is not present even if you use radio and tape, then the sound output IC is blown, and needs replacement. You need to see a professional technician for this. Also, see if your speakers are connected properly. Then try to connect another set of speakers (borow from a friend) and see if sound is audible. If yes, thn your speakers are faulty.

Motor speed needs to be regulated by PWM. Reducing the current (with a resistor) actually lowers the torque - which, with a given load, does result in reduced speed - however, different length tapes (60min vs 90min), as well as different quality, and even current position in the tape, will change the load and hence the speed. You need to regulate the speed via PWM. It's sometimes done on a small board built into the motor, in which case you'd have a round hole into which you could insert an INSULATED screwdriver (tiny flathead wrapped most of the way in electrical tape works). It may be done on the main board, in which case you could find a pot conveniently labeled "motor speed", or perhaps "pulse width" or "pwm" or something to that effect. Find it, mark its current position just in case, and turn it to see if it gets the effect you're after. And there are some tape decks in the world with no speed adjust - they are designed with a specific speed motor and the sizes of the wheels and gears are calculated for that speed. Also there may be a mechanical fault/malfunction causing the speed problem. An initial check and thorough cleaning of the capstan and pinch roller should be done. If there is a buildup of tape oxide or a piece of a broken tape wrapped around the capstan, the tape travel will be too fast (do to the effective increase in capstan shaft diameter). If the pinch roller isn't fully engaging, the tape can be getting pulled onto the takeup spool at a speed faster than the capstan control. A different source of trouble might be a slip clutch (possibly an idler/clutch assembly)which is binding, or otherwise not functioning the way it should. Another type of motor doesn't have it's speed controlled by an internal or external voltage.. instead, the motor has an internal centrifugal speed controller. This type of motor can be found on older tape decks, and might not have been utilized more recently. Good luck
