Service Manual / Schematic for VCR Philips VR948
Hi, I am looking for a Service Manual / Schematic for a VCR from
Philips VR948. It has some very strange behaviour. After power on it accepts commands and than it starts to ignore all commands, whether they come from the remote or the internal operating panel. I have been given the advice to check the mode switch, but I can not locate a typical mode switch. There are a couple of optical sensors and one switch with just one contact. This VCR has a Philips Turbo Drive. Thanks a lot Kevin |

Find and disable the IR sensor for the remote control (not the remote, the receiver part in the unit), if lucky it'll have a connector you can temporarily disconnect. I've had just about everything under the sun with this problem. Usually bad caps (electrolytic) in the sensor group, starts to oscillate and floods the data line with noise. -bruce |
