CD-R playback probably only works when the lens is perfectly aligned. I recently had to refit a laser lens on a 1988 Pioneer CD player with the PWY1010 mechanism and the remaining original glue compromised the vertical alignment of the lens so much that it was unable to playback any CD-R and even many CDs. I had to remove the residue of the original "Pioneer" glue to attach the lens precisely. I had to readjust some of the laser focus offset and tracking settings as well but now the player can playback any CD or CD-R. The required laser power is only slightly different on my player. I can recommend Pritt glue for the laser lens. It's some kind of paper glue mostly made of natural components and can be cleaned with water.
Hello, nice job for this 3rd one! These high end Pioneer were built to last, except for the falling lens problem that is quite common on these reverse chassis. The best is also when no one has tried to fix it with cyano acrylate glue or highly solvanted glues. I have also tried T8000 glue, wich is commonly used to glue smartphone glasses, it's handy with the needle tube! Cyano acrylate glue are largely used when searching evidences in criminal expertise, as their fumes are made of thin particles adhering to any surfaces. It's toxic for lungs, and optics! On these Japanese Pioneer CD players, you normally have wood sides panels. I've also noticed the 4 missing screws on the top: have they been removed with their long specific screws to be replaced by these 4 shorter ones?
As i see and trying to understand the driving mechanism of the laser head is not based on gears and a motor but driven directly electromagnetic through two side coils and fixed magnet plates.Just another high end crazy design.The equipment looks like ultra high priced $$$ in it's epoch,but superseeded after a few years even from the cheapest dvd player.Once i replaced a Pioneer laser head of an upside type around 1998 that costed only as a spare part about 100$.
It's called a linear motor and it is relatively simple in design. The original Philips swing arm used one, the heads on your hard drive use one. Panasonic also used it on their cd players. Simpler, and faster then a mechanical sled, but plastic gears win out on cost.
Hi. Really enjoyed this vid. I own a vintage Pioneer stable platter CD player. Love it! It struggles on occasion locating tracks when I ask it to fast forward or rewind. Any chance that could be because of a stretched belt? Otherwise it works fine. This one is very old, complete with additional copper shielding. Made in Japan, the way gear SHOULD be made. Thanks! :)
HI..What model CD deck is that one you own. This is my CD deck. On this model player the motor shaft engages directly into the center of the turntable, and rotates the platter. The only belts in it, is to load and unload the CD tray and transport mechanism..
Got a pioneer pd 91 that's 30yrs old still going only prob was lens falling off with glue ditirating luckily I didn't use super glue because I put the lens up side down at first with the curve side showing and the flat side glued to me that was the right way but not in this pioneer it wasn't. some of the old players you can no longer get the lasers anymore like my pioneer
Hi sir I have an amplifier aiwa nsx-800 that is not working it gose in some kind of protection when press power button only CD player section has lights. has no sound no function key lights
Have you thought of using something like the Sennheiser binaural headset microphone? Don't know how practical that would be, but it would solve the panning of your voice, and it is still stereo. Really not a major annoyance, because your content is always interesting, but you mentioned it, and now I can't help noticing it. I used a gaming headset boom mic for my last video, which sucks for fidelity, but it really punches the vocal spectrum through. Downside is being connected to a wire, and it picks up nasal air noise.
@@12voltvids I can see that, boundary layer microphone might be another option. They are expensive though, I remember Radio Shack used to sell one at a reasonable price.
@@12voltvids Kind of silly. I was just thinking that I don't own any Pioneer stuff at all but the I realized I have 3 Pioneer laserdisc players. That was one thing Pioneer was best at.
Hello ! mine , a pioneer PD -t05 , I reattached the lens ,after it fell. but it seems can't focus. it seems reading but it won't read the cd contents. it doesn't play.. where can you find the laser focus on this type of player/ > I hope you can help me. thank you.
The disc is upside down so it rests flatly against the platter. Once the disc is clamped down, the platter is supposed to provide the disc with support that helps ensure its stability in rotation. As you may note, the laser pickup is over the disc rather than underneath it to accommodate this design. The two transformers are for two separate power supplies, one for CD player operation and the other for the audio circuits. This is supposed to provide for electrical isolation between these two sections to keep noise in the signal output down to as much of a minimum as possible.
Hey could u help me really quick I got an vcr which only lights up the display but does nothing else no motors spin when Plugin it in. It also does nothing when I stick a cassette in it it doesn't even try to load. What could be wrong? I was thinking missing voltages?
