Remove 7 screws from back cover(4 are same size, 1 is larger: goes into flyback transformer, 2 are small: by the AC cord and A/V jacks. Take the back cover off (pull AC cord thru slot). Remove 2 speaker connectors at front left and right. Remove Degausing coil connector (2 wire, white I think). Remove black wire (Dag. ground) from CRT circuit board (on picture tube).Pull off CRT C.B. from end of pic. tube. Remove 7 screws that secure Cassette Unit to C.B.( 4 in front, 2 high, 2 lower) ( 3 in rear, middle very close to head cylinder). Release 2 locking tabs on bottom of TV while pulling chassis back.Turn chassis on it's side and remove last 2 screws from bottom of circuit board holding Cassette Unit to C.B.(chrome one to right: both are ground screws, but connect to plastic: go figure. Lift unit up slightly (2 cables soldered to main C.B. prevent much free play). Look at the front right (under cass. unit) side and you will see a black round plastic piece (mode select switch) that solders to board and tells MCU what position ( Stop, Play, etc.) cass. unit is in. There's a tip on switch that aligns to a gear on bottom of cass. assy. There's a small circle on C.B. that marks Eject position ( at high noon looking from front or top of TV). Turn loading motor belt to turn gear to turn tip of switch to that position. Hard to be precise from the angle of sight, but easier than you'd think. Set cass. unit down, and make sure tip of mode switch goes into round hole in gear and doesn't move out of Eject position (to prevent it from turning freely). Install a few screws back into cass.unit to hold in place for testing. Remove loading motor belt, holding front pulley so mode switch doesn't move. Slide chassis back in place temporarily and connect CRT circuit board, Dag ground wire, Degauss. coil connector, speaker connectors not needed, but I connect anyway. In order for this to work your cassette housing unit (loads and ejects tape) has to be in eject, or at least out of the way so both end sensors (stop tape at beginning and end) receive infrared light. Also the plastic clear thing ( in center of unit, top, that an LED on C.B. shines infrared light thru has to be in place, so both end sensors send correct logic ( 0 or 5 volts) to MCU. If plastic optic clear thing is broke, you can short end sensor leads together (both sides).They are located on small vertical C.B.'s at left and right, and have only 2 leads that solder to board. Usually these are fine unless major abuse has been done to VCR. Slide chassis to lock tabs, connect cable or input to TV, make sure connectors are in place and keeping a finger on loading motor pulley, plug AC in. If Eject pos. correct, motor should not spin. Push Power button, and TV should come on and not shut down. If OK, unplug AC, and slide chassis back, re-install all screws. Don't reinstall loading motor belt. If motor spins, probably not in Eject pos. Try again, it's not that hard, just avoid high voltage with back off.

A vcr carriage has at least one or maybe two little plugs going to it from the main circuit board, unplug whatever lines that are going to it. don't cut any wires.

My magnavox ZV457MG9 A loads a vcr tape crooked after a tape was stuck in there and we had to pull it out. any resolution to this?

Sounds like a mechanical issue which wasn't helped by forcing part of the carriage downward (I have seen this a million times and worse) You may also have a timing error in your machine which is causing the shutoff when rewind is selected. The carriage is in the wrong position in relation to the mode switch (for eject/load) and is possibly damaged in some way.

Assuming the damage to the carriage loading assembly is minimal to zero, the whole VCR mechanism will have to be re-timed (carriage re-aligned to the position of the guides and take up arm, etc. so that the entire mech is fully ejected and can load correctly) this can only be done in a service workshop by a qualified technician as it is very time consuming and may involve replacing some broken gears on the carriage (which was probably the reason tapes loaded crookedly in the first place), along with clean up and lubrication of other parts.

The good news is that it is a common thing for these to break (flimsy VHS decks with fragile gears) so it isn't too expensive to correct this but you may be without a unit for a few days while they fix the problem. If the cost of repair is reasonable, roll with it.

Everything works fine, replaced RF tuner, fixed carriage elevator, but whenever the VCR is powered on, it tries to eject whether a cassette is in the device or not. Any thoughts?

Try cleaning the mode switch with Servisol Video 40. When you fixed the carriage also, you did get put it back right, in the correct position, otherwise the VCR will think it's in the wrong mode, even if the mode switch is fine!

My vcr does not play the tape

Take the cover off & have a look at the cassette carriage, it may have came out of alignment, ie it is taking the tape at an angle or there maybe a fault with the carriage motor switch. when you put the tape in so far the carraige activates a switch which starts the loading motor to draw the tape in. It could be there is no supply voltage to this switch or the loading motor might be faulty, this is why the VCR says there is no tape as the tape has not been able to load into the machine. A repair centre should be able to fix this fault quite easily.

Vcr tape does not complete loading cycle-stops about 2/3 complete

Your load motor belt is worn or your load gear lubricant had hardened and needs to be cleaned and relubricated.

How to disable the vcr on emerson dvd vcr combo?

Hello sjz4923,
I understand your frustration, however you are not going to want to hear this so what I'll do is just come out and explain why what you are asking is almost impossible, and I'll offer a solution that will help you possibly repair this problem.

The term tv/dvd/vcr combo is a misnomer. The term implies that there are three components in this TV set (TV, VCR, DVD) when in reality there are 1 and 1/2 components in this unit. The TV section of this set is actually the VCR section (RF tuner, IF processor, Video and audio, sync section) what is added to make the TV part of this is the deflection, and High voltage section to power and control the signal to the CRT. As far as the DVD section this basically is a DVD player without the video output, but rather the analog video plugs into the VCR video out. You do have aux ports for DVD video out but these may or may not be amplified video. In a nut shell The TV and the VCR are the same electronics except for the deflection and HV circuits, and the DVD and VCR are separate except for the audio and video main inputs.

So what you are asking is almost impossible since the TV and VCR are the circuit.

Now to repair your problem. What is happening is that the signal that the circuit uses to tell that the VCR carriage is connected properly is not being sensed, what this could mean is the the signal processor is bad or the position control is malfunctioning. The first thing I would do is to make sure that the position control (a wheel on the circuit board which the carriage sets on top of and a peg from the carriage sets into a hole on the wheel) is in sync with the carriage wheel.

Also if you have the equipment you can check the sync signal created by the control and compare it with the signal on the schematic of the TV.

Now having said all of this, if you don't have a background in electronics I would suggest that you get a TV repair technician to work on this problem.

I hope this helps,

Thank you,

TV wont stay on

The vcr carriage was probably damaged ( broken gear or carriage gear, etc ), As for repairing it, it may not be worth it and chances are, you won't find a new carriage for the unit. I have, in the past, disarmed the VCR unit and at least the customer could watch the TV. Thats not possible in every set, but it seems to work in the majority of them. Good Luck

Tape stuck in VCR

First locate the load and unload motor, it is the one with the rubber drive band. release the drive band and rotate the gear to raise and pull the carriage back into position.
This should remove your cassette, and put the carriage back into position.
