How to disable the vcr on emerson dvd vcr combo?
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,
