These old Quasars (matshushita made) have underdesigned power supplies. The electrolytic caps on the output voltages need high voltage ratings. Does it make a high pitch sing? Your unit is running out of power when it gets to the most difficult part of its loading sequence. Try replacing all those caps. Some guy at Matsushita (Panasonic, Magnavox, Quasar) designed many many VCR's and it took him about 10 years to learn that electrolytic caps don't work too good at the high frequencies that switching power supplies have gone to.
Hope Ya Fix It.

Why does the tape get caught in my toshiba rd-xv45kb recorder when i try to eject the cassette and the tape snaps


Not sure about the Toshiba but generally when inserting a cassette it is lowered onto the tape drive. There is a device that will register the presence of a tape which used to commonly be a phototransistor or similar mounted on a short post that is covered by the cassette.

Once the machine knows a tape has been inserted, when play is pressed two vertical rods move towards the heads dragging the tape with them enough for it to make contact with the sound head and wrap part of the way around the video head to make playback possible.

When stop, forward or reverse winding or eject is pressed those two rods move back to the starting position and the surplus tape is wound back into the cassette.

If a cassette ejects leaving a loop of tape that can mostly be pulled out little damaged the reeling in mechanism isn't working. If the tape is jammed and comes free only after breaking the rods aren't returning to the start position.

Engineers use an empty cassette case suitably modified so once the vcr cover has been removed the operation can be observed. The problem might be a worn belt or rubber drive wheel or a problem with the hidden linkages - or it might be an electronic problem.

Start to pay and shuts down


Someone is going to have to look inside, the mechanism that moves the tape has a problem which will cause shutdown, possible belt or mechanical issue.

With cover off and a tape inserted look down at top of cassette and engage in FAST FORWARD----do reels in the cassette move quickly or not-----Sometimes if a worn belt or drive idler running the tape back and forth with fast forward and rewind will cure the issue for a short time----no movement equals no motion and unit should shut down.

My Sony TC WR 535 wont open doors, one cassette in deck B,lights blinked in display panel then unit shut down, not been able to turn it on since


Remove the cover after unplugging AC. Look for a plastic stop that keeps the eject button from going in farther. Move the plastic stop peice downward and the buttom will then move in all the way and tape will eject. On mine the plastic piece is white and rotates down.

I have a Brother label maker, model number pt65. How do I install the tape. I cant get it to feed through. Thank You


1) Remove the back cover by pressing in on the rough
area at the top end of the machine and pulling off the
back cover.

2) If a tape cassette is already installed, pull it straight out
and remove the paper tab from the new tape cassette.
Make sure that the end of the tape in the new cassette
feeds under the tape guides.

3) Insert the tape cassette, making sure that it clicks into place.
Check that the cassette fits properly around the two
metal guides in the cassette compartment.

4) Attach the back cover by inserting the two hooks on the
bottom end of the back cover into the slots on the bottom
end of the machine, then pushing down firmly on
the cover until it snaps into place.
5) Feed the tape by holding down and pressing ,
then cut the tape by pressing in on the tape cutter button.
The amount of tape remaining is visible through the
window in the back of the P-Touch.
When the usable tape is finished, green ribbon appears

Hope this helps

Denon Dual Cassette Deck DRW-660 will not eject either tape. I put a tape in right side, played a bit, stopped, will not eject. I put another tape in left side, closed, cannot eject. Cannot eject either....


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

Can't insert tape into deck


Remove the cover again and move the tape carriage all the way towards the front (the carriage is not fully in the locked position). Once that is done you should be able to load a cassette again.

The unit will fast forward and rewind, but won't play


This is a problem with the process called 'tape loading' - pulling the tape loop out of the cassette and wrapping it around the spinning video drum, engaging the capstan and pinch roller and reel rotation. Check all the belts above and below the deck. Belts can appear to be firm but if they do not return immediately to their relaxed length when you stretch them 25%, they will need to be replaced. With the cover off, observe the behavior when you hit play. (You may need to put a piece of cardboard over the cassette to block external light from interfering with the start/end tape sensors). Assuming this is a basic VCR (no instant start features), you should see: 1. The video head drum begins to spin. 2. the roller guides move smoothly on the tracks, wind the tape around the drum, and stop snuggly pressed against the 'V-stopper' at the end of the tracks. 3. The pinch roller moves into position and presses the tape against the capstan. 4. The tape begins to move and is wound up by the takeup reel. 5. The picture and sound appear on the TV. With a 'rapid or quick start' (or it may be called something else) transport, the tape moves to a half-loaded position when the cassette is inserted. This is at an intermediate position partially pulled out of the cassette but not wrapped around the drum. On VCRs with a real-time counter and/or index search capabilities, the tape will be in contact with the control head. With an 'instant start' transport, the tape will fully load around the spinning drum when the cassette is inserted but the capstan will not engage and no tension will be applied to the tape until you press PLAY or REC. (After about 5 minutes, the drum will stop and it may unload to the half loaded or unloaded position.) Note that for VCRs with a real-time counter and/or index search capabilities, the tape must be in contact with the control head (but not the video heads) for all relevant modes. These VCRs (which include many modern units) must therefore pull the tape at least partly out of the cassette. In all cases, the completion of the sequence results in approximately the same mechanical configuration during PLAY. Several likely possibilities when it shuts down: 1. Everything occurs as above, picture and sound appear for a few seconds, but then the VCR unloads the tape, ejects the cassette, goes into REW mode, stops, or shuts off. Two common causes: The takeup reel does not turn and tape spills into the machine. This is sensed by the microcontroller which aborts record or play and attempts to save your valuable cassette. Most likely cause: old/dirty idler tire. As a test, turn the idler tire inside-out. The fresh surface will now work well enough to confirm this diagnosis and will continue working long enough for your replacement idler tire to arrive. See the section: "General guide to VCR cleaning and rubber parts replacement". The takeup reel is turning properly but
