Another way to clean Philips bald head [Copy link]

The article on cleaning Philips VCD laser heads published in the Electronics Newspaper is very practical. I have repaired many Philips laser heads according to its method. However, the method in the newspaper is more troublesome to disassemble and assemble the laser head. If there is a slight deviation during assembly, the laser head will not work. After experiments, I have summarized another simple and practical method, which I now recommend to my colleagues for reference.　　

The specific steps are: (1) Remove the laser head from the core and short-circuit the cable with an electrostatic protection clip. (2) Use a small "-" screwdriver to gently pry the laser tube off the laser head from the narrow gap on both sides of the laser tube. (3) Mix laundry detergent with clean water to make a 10% to 15% solution, and soak the laser head in the solution for about fifteen minutes. (4) Take out the laser head and rinse it repeatedly under the tap, especially the hole where the laser tube is installed. You can block the tap with your fingers to make the water flow into a thin beam to increase the water pressure and thoroughly rinse the hole. Then rinse the laser head twice in pure drinking water. (5) Shake off the moisture on the laser head, place the laser head in the sun for 30 minutes, check that the laser head is completely dry and has no water droplets, reset the laser tube and reinforce it with a small amount of AB glue, then install it for use. If you need to use a hair dryer to dry the moisture on a cloudy day, be careful not to deform the plastic part of the laser head, otherwise it will be scrapped.　　

This method is also suitable for cleaning laser heads such as Sony and Samsung. Note that there should not be any deviation when assembling the laser tube of Sony, Samsung and other laser heads. Please be careful when operating.
