Question about JVC HR-S9400 S-VHS VCR
When turning on the VCR it will go into standby. When the power is turned on it goes through its routine of checks and then goes back into standby. I took this VCR to a friend of mine who used to repair VCRs and he tells me its the main processor in the VCR that has broken and I need a new one. This processor is apparently a silver square thing (bit bigger than a postage stamp) on the ICB that is apparently held in by some 30 pins and you need a special piece of kit to remove it? Anyway, what I could do with knowing is what this is called, both the actual name and the id number I need to order from JVC. Incidentally, my friend did all the checks on belts, motors and all that good stuff, and they were all working fine. Really appreciate any help as it's a nice VCR and has seen little use, especially since this problem occurred! ;-)
Hi
problem:-
When turning on the VCR it will go into standby. When the power is turned on it goes through its routine of checks and then goes back into standby.
solution :- there is a cluster of IC protection fuses on the main
power board underneath. These fuses look like transistors ie black semicircular body. These components are linked to the
direct drive motor. The component in question is the IC protection fuse named CP801. It is a 2 legged component
classified as an N20. This means it is an 800mA semiconductor fuse. Calculated 20 x 40mA = 800ma.
The problem is this component becomes open circuit (blown fuse).
Suppliers class this as an IC protector fuse ICP-N20.
These components have been used on JVC boards for years.
Possible reasons for fuse blowing could be as loading tape the tension on tape my require a higher load being pulled from the motor, so knocking it over the threshold of the fuse.
Mine blows once every 5 years. I think a common problem.
hope this helps

That square thing called processor is a IC the number is written on the top of the case just write down the number and order it by the same number.good luck
