VCR goes into standby after powering up and going through its initial checks
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! ;-)

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.

Hi, try powering up the unit with out any speaker connected if it still goes to PROTECT try factory reset if possible.
To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter standby mode.
If this does not fix your problem you should take your unit to service . :)
Alright, so wait, explain that again, It stops working when your using it, or when it goes into standby?
It starts working again after what? When you come out of standby?
When going into standby, the system goes on low power may cut the power to your speakers.
Check your Power settings.
RIGHT CLICK on DESKTOP> Select properties, Go to screen saver Tab and click on the Power button, then check all the power options such as when it goes into standby, how long till it does and adjust them to your preferences, also make sure Hibernation is turned off as well, when it goes into Hubernation, it cuts almost everything.
If this unit shuts down after you turn it on, it is going into stanby because the microprocessor is not seeing the proper pulses from the mode switch. this could be due to an out of time mechanism because of a broken gear, bad mode switch, the loading basket is out of time or broken, or the capstain motor or the cylinlinder motor is not sending the PG and FG pulses to the microprocessor. These can also be due to a power supply voltage missing. You can check the voltages with a service manual and make sure they are not low. You will also need to get the mechanism manual and check the timing of the mechanism. Then check the mode switch you can get a manual from here http://www.servicemanuals.net/results.aspx?brand=15&model=HRS&type=SM&pos=281 Good Luck
