I have a single cassette deck Philips DC 900 when you hit the play button,it plays for about 5 seconds then stops and head retracts. Belts have been replaced

Belts, and the pinch roller are common wear parts that should be changed. This could most likely be your problem with this device.

It is problem in Take-up Reel section and its not sending signal to processor. How old is this unit?

It sounds like the belt is slipping or broken which monitors the speed of the tape movement. When you play or rewind the tape, it thinks the tape has reached the end of play and shuts off. You can try a different tape to make sure the tape does not have too much tension on it. If the second tape has the same result you will need to remove the top cover of the deck to inspect the tape drive mechanism. Make sure the belts and pulleys are clean and replace any belts which have glazing or cracks. If the belt is broken you will need to replace it with a compatible belt of the same length and width.

get some q-tips, peroxide. power off and a cassette tape you been playing...open compartment door... poor a cap full of peroxide in cap.. take one q-tip dip in peroxide.. now take q-tip and wipe the recording head, erase head and play head (do not saturate) each tip should be black or dark brown now take another q-tip to dry the same heads and the roller... let the air hit it for about 5 min... power on insert tape press play ... how do it sound...

Needs two new 8" drive belts. They install in 5 mins and cost just a few bucks. [email protected] if you need more help.

Take it to a Panasonic authorized service center. They'll fix it.

Suggest having a good clean and replace belts. If it stops around halfway on a C90 or near the end then there's a load problem on the take up reel, before halfway the supply reel.

Belts have become too slack to allow mechanism drive. Have replaced

Some dual decks use a common drive belt. It may have become too slack (due to age) to drive mechanism. I am sure its time to change all belts in both decks. This will solve the problem

Sounds like the tape tension sensor is stuck. The sensor is always telling the mechanism that the tape has reached the end.
