Question about Samsung SV5000W VHS VCR
Just completed my Diploma in Electronics and want to do a lot of practicals. My samsung SV5000W VCR power only in stanby mode. I do not have a full power. I removed the mechanical part and see if I can have a full power but it still the same. I have try all the troubleshooting technics I know but can't get the power back in full mode. Can I get any assistance please?.
VCRs are both mechanical and electrical. Mechanical things usualy fail in these first because of wear and heat. They use this thing inside called a mode switch. What it does is makes contacts to different sections of the unit depending on what mode its in. These are common to fail because they control motors and motors can draw more current as they get old. They also use gears that are timmed. If the timming gets off they can be tricky to reset. It sounds like the mod switch has a bad spot in it and when its in a certin mode its not making contact to the section with no power. Once the mode switch gets to a different point the contact is good and power is fine. The mode switch is usualy under the mechanical section near the capstan and the drive gears. Some times its in the back near a motor with a worm gear. You can clean them with a pencil eraser
